Abstract (sommario):

Sweet corn has a very short period of optimum harvest maturity, and its quality changes rapidly close to and following the peak. The aim of this study was to determine the sweet corn quality on the ground of some physicochemical properties of intact kernels (moisture content, compression, shear and puncture force, bulk density, sugar and starch contents) and cut kernels (processing recovery, cut corn yield) at four subsequent harvest dates. The moisture content, sugars level, and ear yield decreased. The starch level, bulk density (intact and cut kernels), compression force, shear force and puncture force, processing recovery and cut corn yield increased. The first harvest date showed a greater advantage in the higher sweet corn quality for processing than the following harvest date. The moisture decreased from 77.41% to 69.83% with delayed harvest date. A decline was observed of sweet corn quality (increase of force in compression, shear and puncture tests, raise in the starch level). However, the following harvest date had an advantage in a higher processing recovery and cut corn yield.

Abstract (sommario):

Plant-to-plant variation for corn (Zea mays L.) forage-quality traits has not been adequately described. A field study was conducted for 2 yr, using hybrids with a range in maturation, each grown at two sites. Precipitation and temperature deviated considerably from normal in both growing seasons. Ten consecutive plants were harvested from each plot and separately analyzed for forage-quality traits. Differences among the forage-quality variables were consistent for the hybrid maturity groups, and data were pooled for analysis. When the product of variance × total cost was minimized, sample size was not greatly different for any of the measured variables when the cost ratio was low. If the cost per plot is 10 times that of the cost per plant, the product of variance × total cost is minimized at 9 plants plot−1 for whole-plant digestibility. When detection limits were considered but not costs, whole-plant digestibility was the least variable trait and grain proportion was the most variable trait among the traits measured. If a detectable difference of 20 g kg−1 in whole-plant digestibility between hybrids is desired, it would require sampling 4 plants plot−1, while a difference of 20 g kg−1 in stover digestibility could not be detected with an infinite number of plants per plot. Grain proportion explained a relatively small portion of the variation in whole-plant digestibility and was better related to stover-quality traits. Key words: Corn, maize, forage quality, variation, stover, grain

Abstract (sommario):

Introduction. Producing new maize cultivars in areas with limited water resources is the main task of plant breeders. However, there is little information regarding their technological characteristics and industrial potential. Besides, snacks have gained worldwide acceptability and become part of modern food culture, especially among young people and children. Thus, our study aimed to produce corn snacks from new yellow corn hybrids planted under water stress in Delta region, Egypt. Study objects and methods. We investigated healthy processing techniques and used nixtamalization and baking instead of frying. We also evaluated the chemical composition and starch crystallinity of flour, the rheological properties of dough, as well as color attributes and sensory characteristics of baked snacks. Results and discussion. Significant differences (P ˂ 0.05) were found between all corn genotypes in their fat, protein, ash, crude fiber, and carbohydrate contents. The experimental drought conditions caused higher protein and fat contents compared to normal conditions. X-ray diffraction indicated that nixtamalization decreased starch crystallinity. Also, X-ray and rapid visco analysis showed that Y2 genotype exhibited the highest crystallinity and the lowest pasting properties, while Y3 and Y5 had the lowest crystallinity and the highest pasting properties. Baked snacks made from nixtamalized corn flour of genotypes planted under drought conditions had comparable quality characteristics in terms of color and sensory properties to the control snacks made from SC178 genotype planted under normal conditions. Conclusion. The new corn hybrids grown in limited water conditions and the developed snacks represent a healthy alternative to cornbased fried snacks.

Abstract (sommario):

The rapid growth of corn-based dry grind ethanol plants over the past decade in the US has resulted in a great increase in production of the coproduct DDGS (distillers dried grains with solubles). Since some physical properties like low bulk density and poor flowability can impact the market potential of DDGS, pelleting of DDGS can be one of the easiest ways to improve this situation. Pellet quality is the focus of this project. The pelleting process was conducted with three initial DDGS moisture contents and two different dies; a total of six runs were completed to produce DDGS pellets. The physical qualities of pelleted DDGS were determined by measuring durability, bulk density, angle of repose, and color of the pellets. The results showed that the durability ranged from 42% to 89%, the highest pellet durability occurred when the moisture content was 20% db and the die diameter was 1/8 in. The bulk density increased when the DDGS moisture content decreased, and the highest bulk density was observed when the moisture content was 10% db and the die diameter was 1/8 in.

Abstract (sommario):

Supersweet corn with the shrunken-2 gene (sh2) has shown good quality after frozen storage. A study was undertaken to further evaluate the quality of supersweet corn (cv Florida Staysweet) unblanched or blanched then frozen. Samples were evaluated every 4 months for 12 months for peroxidase activity. sugar composition, water soluble polysaccharides and organoleptic qualities. Peroxidese activity changed in unblanched corn at each sampling date, which was consistently higher than in blanched corn. Sucrose and total sugars declined during storage. Sucrose was highest in blenched samples and reducing sugars were highest in unblanched samples. WSP content was low in all samples, but lower in blenched compared to unblanched samples. Taste panelists discerned differences between blanched and unblanched corn at 8 months when blanched samples were rated as more yellow than unblanched. However, no differences were found for taste between blanched and unblanched samples for taste at 12 months. These results indicate that sh2 sweetcorn maintained good eating quality for 12 months of frozen storage with or without blanching.

Abstract (sommario):

Rainwater harvesting can provide an alternative water source, which may demand little treatment, depending on the end use. Some starches have been used in water treatment as coagulant/flocculant/filtration aid, and might be applied as primary coagulant. Here, we show direct filtration with hydraulic rapid mixing, using 2–6 mg L−1 cationic corn starch as primary coagulant, considerably improves roof-harvested rainwater quality, achieving removal efficiencies of up to 71.7% of apparent colour, 78% of turbidity, 1.1 log-unit of total coliform, and 1.6 log-unit of Escherichia coli, meeting guidelines for turbidity, even for potable purposes. Cationic corn starch has proved to be a suitable primary coagulant when filtration is performed in a single-layer sand filter (coefficient of uniformity: 1.8, effective particle size: 0.52 mm), at hydraulic loading rate of 450 m day−1. However, a disinfection unit is required to meet an absence of faecal coliform.

Abstract (sommario):

ABSTRACT Harvesting time is one of the main factors that influences grain quality, largely due to their exposure to biotic and abiotic factors during pre-harvest. As such, this study aimed to assess corn grain quality in response to different harvesting times in the municipality of Campo Novo do Parecis, Mato Grosso state, Brazil. A randomized block design was used with a strip-plot scheme, consisting of three corn hybrids (NS90 PRO, NS92 PRO 2 and BG7439), five harvesting times (0, 7, 14, 21 and 28 days after physiological maturity - DAPM), with three repetitions. The variables grain yield, 1000 grain weight, bulk density, electrical conductivity and proximate composition were analyzed at each of the proposed harvesting times and lipid composition was assessed only at 0 and 28 DAPM. Data were submitted to ANOVA, regression analysis and Tukey’s test (p ≤ 0.05). Delayed harvesting influenced all the variables studied, except ash concentration. The longer the grains remain on the plant after physiological maturity, the worse the grain yield and their physical, chemical and nutritional quality.

Abstract (sommario):

Root or stalk lodging can be a serious problem in sweet corn (Zea mays L.) production. Four dent corn inbreds, crossed to five sweet corn inbreds in a design II mating system, and a half diallel with five sweet corn inbreds were used to 1) determine the effect and potential contribution of dent corn germplasm on stalk and root quality traits in sweet corn, 2) examine the variation for stalk and root quality traits in some sweet corn germplasm, and 3) evaluate the utility of traits used in improving dent corn root and stalk quality in sweet corn improvement. The dent corn germplasm used in this study had a favorable affect on stalk and root quality in the dent × sweet hybrids. Compared to the sweet × sweet hybrids, the dent × sweet hybrids had significantly higher stalk crushing strength and stalk soluble carbohydrates, while having significantly less stalk lodging. The mean stalk lodging for the dent × sweet hybrids was 4.4%, while the sweet × sweet hybrids averaged 18.7%. Within the diallel, effects due to hybrids were highly significant for stalk section weight, rind thickness, and stalk diameter. Percent stalk lodging was negatively correlated with stalk section weight [r = (-0.63), P ≤ 0.05] and crushing strength [r = (-0.64), P ≤ 0.05]. No traits were significantly correlated with root lodging within the sweet corn crosses. Dent corn has potential as a source of improved stalk and root quality in sweet corn.

Abstract (sommario):

ABSTRACT: Corn and sorghum are standard silage crops because of their fermentative characteristics. While corn and sorghum silages have lower crude protein (CP) contents than other crops, intercropping with legumes can increase CP content. Furthermore, one way to increase CP content is the addition of legumes to silage. Consequently, the research objective was to evaluate the fermentative and bromatological characteristics of corn (Zea mays) and sorghum (Sorghum bicolor) silages added with forage peanuts (Arachis pintoi). The experimental design was completely randomized with four replicates. The treatments consisted of corn silage, sorghum silage, forage peanut silage, corn silage with 30% forage peanut, and sorghum silage with 30% forage peanut. The results showed that the corn and sorghum added with peanut helped to improve the silage fermentative and bromatological characteristics, proving to be an efficient technique for silage quality. The forage peanut silage had lower fermentative characteristics than the corn and sorghum silages. However, the forage peanut silage had a greater CP content, which increased the protein contents of the corn and sorghum silages when intercropped with forage peanuts.

Abstract (sommario):

Land continuously planted with corn will decrease land quality. Good land quality is needed to support soil function as a growing medium and keep a sustainable environment. This research was aimed to identify the soil quality index at land unit planted with corn in Mungka, ,Lima Puluh Kota Regency. This research used an explorative descriptive method through land survey and soil analyses in the laboratory. The samples were taken based on purposive random sampling at each land unit under the same slope (8%). There were three land units being sampled, and those were corn-corn, corn-eggplant, and corn-cassava cropping pattern. Corn-corn ropping pattern had the best soil quality index (0.89), followed by corn-cassava (0.86), and corn-eggplant (0.85) on the top 20 cm soil depth. On the 20-40 cm soil depth, the soil quality indices 0.82, 0.82, 0.83, for corn-eggplant, corn-corn, and corn-cassava cropping pattern, respectively. The quality index of the land under the corn cropping pattern was considered good either on the top 0-20 cm or 20-40 cm soil depth. This was due to the addition of organic matter from poultry manure to the land regularly. Based on this research, it is recommended to apply OM regularly to corn cropping pattern to keep a good soil quality index.

Abstract (sommario):

The management of the inoculation of a plant’s roots, by means of biofertilizers (BF) containing arbuscular mycorrhizal (AM) fungi, is aimed at inducing modifications of the quality of the seeds. It is here shown that a seed-soil treatment can be elicited in the fingerprints of a symbiotic treatment using Near Infra Red (NIR)-SCiO NIR-SCiO spectra collections of single kernels: overall, a sensitivity of 73% and a specificity of 73% have been achieved, thus suggesting that it may be possible to assign the symbiotic origin of corn from just twenty kernels, provided that the dataset is adequately representative of the cultivar and AM. A global correlation study has shown a positive general trend (R2 0.45) of quality vs. quantity, in the sense that an increase in yield corresponded to an increase in the spectral differences between the symbiotic spectra and the control ones, but the inverse was also true, as a result of the parasitic behaviour of the BF treatments. The efficacy of the symbiosis can be back predicted from the NIR spectra; in fact, around 90% of the positive yield outcome results were discriminated from the negative ones. A reduction in the foliar pH (R2 0.37) and an increase in the foliar protein (R2 0.43) were observed as immediate phenotypic signs of a productive symbiosis. The commercial raw composition of the kernels appeared to only be affected slightly by the BF treatments; thus, till now uncharted secondary compounds of the maize kernels are involved, as supported by animal performances.

Abstract (sommario):

Effects of partial replacement of wheat flour with corn flour (2.93–17.07%) blended with xanthan gum (0.1172–0.6828%) on physical properties, textural and sensory characteristics of sponge cakes were evaluated by response surface methodology (RSM). The significant regression models (P ≤ 0.05) were established to explain the influence of corn flour and xanthan (Xan) on the dependent variables and optimize the formulation. Xanthan significantly increased moisture content, hardness and chewiness, but it decreased specific volume and springiness (P ≤ 0.001). Corn flour had significant positive effects on specific volume, hardness, springiness, colour and overall acceptability (P ≤ 0.05). Hence corn flour and xanthan significantly improved the baking quality of sponge cakes (P ≤ 0.05) and thereby augmented the potential for using wheat-corn blend flours in cake baking. Based on RSM optimisation, a balance between amounts of corn flour (12.7%) and xanthan (0.416%) led to products with desired physical properties and acceptable sensory quality.

Abstract (sommario):

Pea (Pisum sativum L.) are grown for canning and freezing on over 40 000 ha (1979–1982 average) in Wisconsin and substantial acreages are also seeded to other canning crops. The majority of this land remains idle after harvest in late June or early July. Crops could be seeded on this land to be used as forage for livestock or for energy conversion. The objective of this study was to evaluate the yield and forage quality of several summer annual crops seeded after pea harvest. Field experiments were conducted during 1980 and 1981 on a Piano silt loam soil (Typic Argiudoll) at Arlington, Wisconsin. ’Alaska’ pea were planted in late April and harvested in late June. After pea harvest, plots were cultivated to prepare a seedbed for the second crops, which were planted in late June. The second crops included three sorghum (Sorghum bicolor (L.) Moench) cultivars, soybean (Glycine max L.), normal and male-sterile early maturity (RM 95) corn (Zea mays L.), and two mixed cropping systems. Mixed crops were male-sterile corn grown with either soybean or field bean (Phaseolus vulgaris L.). Second crops were harvested late in September. Male-sterile corn had the highest 2-yr average yield of DM at 9.8 Mg∙ha−1 and sweet sorghum had the second highest yield even though it was reseeded 13 days later in 1981 due to poor germination. The normal corn average yield was only 0.5 Mg∙ha−1 less than that of sweet sorghum and should be considered a viable option as a second crop after canning pea harvest. Soybean would not be recommended for this use because its yield was considerably below that of any other crop in both years. Soybean forage was highest in N and lowest in NDF. Of the grass crops the highest IVDMD values were for normal corn (64.2%), male-sterile corn (63.7%), and sweet sorghum (64.9%). Sorghum-sudangrass was lowest in IVDMD in 1980 (53.0%) and in 1981 (60.1%). Sweet sorghum and the two corn types were lower in neutral detergent fiber, acid detergent fiber and acid detergent lignin than sorghum-sudangrass. Considering both yield of DM and the quality of the forage produced, male-sterile corn, sweet sorghum and normal corn can be identified as the superior crops for planting after pea harvest. Mixed cropping male-sterile corn with soybean or field bean gave no advantage in yield or quality.Key words: Corn, sorghum, pea, IVDMD, NDF, N

Abstract (sommario):

Abstract: The objective of this work was to evaluate methods of intercropping corn and Panicum spp. forages and their effects on corn yield and forage development. Two experiments with Panicum spp. were conducted, one with 'Tanzania' and other with 'Massai' in the municipality of Piracicaba, in the state of São Paulo, Brazil, in the 2012/2013 growing season. In both experiments, the treatments were: broadcast seeding of Panicum spp. at the same time of corn sowing; corn with Panicum spp. between rows; Panicum spp. sown with fertilizer; Panicum spp. sown between corn rows after corn establishment; broadcast seeding of Panicum spp. after corn establishment; and sole corn sowing. For corn, leaf nitrogen content, ear height, and grain yield were evaluated. For Panicum spp. cultivars, height, dry mass, tiller density, and leaf:stem ratio were evaluated. The intercropping establishment methods used do not affect corn growth, grain yield, and N leaf content. The seeding of both cultivars of Panicum spp. when corn plants had four expanded leaves reduces forage dry mass production and increases the leaf:stem ratio. The Panicum spp. broadcast method, performed after corn was established, does not allow appropriate establishment, with few plants in the area.

Abstract (sommario):

Two experiments (exp. 1 and exp. 2, respectively) were conducted to compare performance, pork quality, and excretion characteristics of pigs fed diets containing Bt 11 (Bt) or control corn (C: non-transgenic inbred lines for exp. 1, and a non-transgenic isoline for exp. 2). Experiment 1 involved barrows and gilts (total n = 64; initial BW = 64 kg and 60 kg), while in exp. 2, 120 barrows were used (initial BW = 17 kg). Pigs were allocated to pens, blocked by sex and BW. Isocaloric, isolysinic diets contained an indigestible marker in exp. 1. Feed disappearance and weight gain data, and excreta samples were collected weekly in exp. 1. Feed disappearance and weight gain data were collected weekly in exp. 2. No difference in ADG was observed, however, feed efficiency was greater for pigs fed the C diet. No corn effects were observed for hot carcass weight, loin eye area, or backfat depth. Hunter color ‘b’ values and values for chroma were significantly greater for pigs fed C diets (P = 0.02, < 0.01, respectively) in exp. 1. In contrast, Hunter color ‘b’ values were significantly lower for pigs fed C diets (P = 0.05) in exp. 2. No corn effects were observed for proximate analyses of meat samples, N or P content of fecal and urine samples, nor N digestibility. Pigs fed C diets had greater apparent P digestibility (57.8% vs. 40.2%; P < 0.0001). Key words: Bt corn, animal performance, excretion

Abstract (sommario):

To identify the microwave drying characteristics of corn, microwave drying tests were conducted on corn. By taking the moisture content, drying rate, and drying temperature as indices, this research revealed the effects of different microwave powers and loads on the microwave drying characteristics of corn. Moreover, energy consumption and quality of dried corn were analysed under different drying conditions. The results demonstrate that microwave drying has significant energy-saving effects. The energy consumption by microwave drying is less than 0.3 times that used by electrothermal drying under the same load. Both microwave power and load exert significant influences on drying characteristics. Higher microwave power results in a greater average drying rate, wherein shorter periods of time are required to reach the maximum drying rate and higher temperatures of the corn. However, the load shows the opposite tendency. The smaller the load, the higher the temperature of the corn in the early stage of drying. However, as drying continues, the temperature curve changes significantly, and the temperature rises with the increase in load in the later stage of drying. In consideration of energy consumption and dried quality, the load of corn should be increased as appropriate, and the microwave intensity should be limited to no higher than 0.7 W/g in the experiment.
