Résumé :

The present research on efficacy of botanicals against pulse beetle in stored chickpea was conducted under laboratory conditions at Department of Entomology, SHUATS, Prayagraj, India during 2020-2021. The experiment was carried in the Completely Randomized Design with twelve treatments (Neem oil, Castor oil, Pungam oil and plant powders neem leaf powder, neem seed kernel powder, Vasambu rhizome powder, Turmeric powder, Custard apple leaf powder, Eucalyptus leaf powder, Lantana camara leaf powder, Notchi leaf powder, insecticide (Rynaxypyr) and untreated control. The results were evaluated on the basis of adult mortality, weight loss and Feeding Detterent Index. Vasambu rhizome powder, Neem oil, Castor oil, and Pungam oil were discovered to be the most successful treatments, demonstrating 100% adult mortality, negligible weight loss, and 100% Feeding Detterent Index.The effectiveness of the plant oils is due to their repellency and ovipositional detterent effects on stored products and the effeciency of vasambu rhizome powder was due to the presence of active principle, keta osarone which induces premature death of insects.

Résumé :

The study was conducted in the Laboratory of Plant Science and Biotechnology Department, Federal University of Lafia, Nasarawa State to investigate the insecticidal potency of three spices powder namely black pepper (Piper nigrum L.), ginger (Zingiber officinale L.), and true green (Ellectaria cardamom L.), against wheat weevil (Tribolium castaneum) on stored wheat grain. Spices powder was added separately to 20g of wheat grain in plastic containers at four dosages 0.15, 0.27, 0.37, and 0.5% (w/w) while control had no spices powder. Twenty insect pests (Tribolium castaneum) were introduced into each container. Mortality counted in each treatment was recorded after 7, 14, 21, 28 and 35 days. All treatments were replicated three times. Variations were significantly observed in the overall effect of different plant powders on the mortality of weevils extracted from wheat kernel. Weevils treated with Piper nigrum powder exhibited the highest mean mortality (16.37), followed by Ellectaria cardamom (16.05) and lastly Zingiber officinale (13.82). from the result obtained, it is evident that the spice powders possessed insecticidal properties which if fully extracted could be used in post harvest treatment of wheat grain on storage

Résumé :

Specific activities of phenolic compounds produced from the fruiting bodies of the fungi PO and AB (the locally produced strain in Iraq) obtained from the Department of Plant Protection - Department of Organic Agriculture - Baghdad - Iraq were studied. Then, the phenolic compounds were determined after cleaning, drying and grinding the fruiting bodies. The alcoholic extract of the two fungi was prepared by adding 0.2 g of fruiting bodies powder per (1) ml of 98% ethyl alcohol, where the mixture was filtered, concentrated and kept in the refrigerator until use. The aqueous extract was prepared by adding 25 g of fruiting bodies powder per 500 ml of boiled distilled water. Similarly, the mixture was mixed, filtered and stored in the refrigerator until use. The study findings confirmed the existence of significant differences at the probability level (P ˂ 0.05) for the alcoholic and aqueous extracts and for the fungi in the content of phenolic compounds. Conversely, the reducing power was increased by increasing the concentrations prepared for the extracts prepared from the two fungi under study. The free radical scavenging method DPPH was used to estimate the antioxidant activity of alcoholic and aqueous extracts and of the fungi PO and AB. Thus, the results showed the superiority of ethyl acetate extract compared to the other used solvents. Keywords: Edible fungi, phenolic compounds, reducing power, free radical scavenging.

Résumé :

The aim of the study is to determine the possibility of using kelp and black chokeberry powders in bake¬ry product recipes. Objectives: to study the effect of powders on dough quality in various dosages and determine their optimal content; evaluate the quality indicators of finished products. The study was conducted at the Food Technology Department of the Northern Trans-Urals State Agricultural University. The objects of the study were semi-finished wheat bread products with the addition of kelp powder in the amount of 0.5; 1.0; 1.5 and 2 % to the flour weight; semi-finished bakery products with the addition of black chokeberry powder in the amount of 1; 3; 5; 7 % to the flour weight. The addition of kelp powder when kneading the dough increases the water absorption capacity of the dough compared to the control, which has a strengthening effect on the dough structure. The addition of black chokeberry powder to the dough redu¬ces the mass fraction of raw gluten, but also has a strengthening effect. The optimal dosage of kelp powder for adding to the recipe for wheat bread made from premium flour has been established – 2 %, and black chokeberry powder for buns – 3 % of the flour weight. The addition of kelp powder to finished pro¬ducts had the most noticeable effect on the shape and condition of the surface, the size and uniformity of the pore distribution, which can be associated with a greater water absorption capacity of the dough. The addition of black chokeberry powder to the recipe for bakery products had a positive effect on the organoleptic indicators, giving the finished products a pleasant berry taste and aroma. Bakery products were characterized by greater dimensional stability, uniform thin-walled porosity.

Résumé :

Moringa (Moringa oleifera), indigenous to India and Africa, is esteemed for its dual utility as a minor timber source and, more importantly, as a vegetable crop. The leaves of the moringa tree are exceptionally nutrient-dense, containing essential elements such as iron, calcium, proteins, vitamins A, C, and E, dietary fiber, phosphorus, and potassium, all vital for human health. Furthermore, these leaves are rich in antioxidants, including flavonoids and phenolics, which endow them with significant medicinal properties. Despite its sporadic cultivation hindering global availability, the production of moringa leaf powder presents a viable strategy to bolster its international export potential. This study aims to assess the efficacy of various drying techniques in producing moringa leaf powder while preserving its nutritional integrity. Conducted at the Post-Harvest Technology Laboratory within the Department of Horticulture, Rajasthan College of Agriculture, and the Department of Processing and Food Engineering, College of Technology and Agricultural Engineering at Maharana Pratap University of Agriculture and Technology, Udaipur, Rajasthan, India, this research evaluates the nutritional quality of moringa leaf powder produced via different drying methods and from leaves of varying ages. Our findings indicate that the fluidized bed dryer excels in preserving the nutritional quality of the powder compared to tray and heat pump dryers. Additionally, the study concludes that heat pump dryers are unsuitable for producing high-quality moringa leaf powder.

Résumé :

AbstractCemented carbide tools suffer from many issues due to the use of tungsten and cobalt as raw materials. Indeed, those are listed by the European Commission as “critical raw materials” since 2011 and by the US Department of Interior as “critical minerals” in 2018. To remain competitive with the conventional high-speed steels, less performant but cheaper, WC–Co tools can be recycled. In the present paper, a WC–7.5Co powder, recycled by the “Coldstream” process, has been sintered with vacuum sintering. As preliminary experiments have shown that the sinterability of the powder is low, the sintering temperature was set at 1500 °C to achieve full density. In parallel, the influence of ball milling conditions (rotation speed and milling medium) on the reactivity of the recycled powder has been studied in terms of grain size distribution, hardness, and fracture toughness. The optimized milling conditions were found to be 6 h wet milling, leading to a hardness of about 1870 HV30 and a toughness of about 10.5 MPa√m after densification. The recycled powder can thus totally compete with conventional powders, opening avenues for the recycling of cemented carbide tools. Graphical Abstract

Résumé :

Grain storage plays a pivotal role in ensuring food security and sustaining agriculture for future generations. However, a wide array of insect pests, including the rice weevil (Sitophilus oryzae), pose a significant threat to stored grains. This study was conducted at the Laboratory of the Department of Seed Science and Technology, Bangladesh Agricultural University, Mymensingh, from October 2019 to March 2020, to evaluate the efficacy of plant-based powders for managing rice weevils. The experiment was designed using a Completely Randomized Design (CRD) with three replications and seven treatments. These treatments included five botanical powders—Ocimum tenuiflorum (Tulsi), Azadirachta indica (Neem), Polygonum hydropiper (Biskatali), Nicotiana tabacum (Tobacco), and Lantana camara (Lantana)—applied at three dosage levels: 1 g, 3 g, and 5 g per 100 g of grain. Additionally, a chemical insecticide (Sevin 85 SP @ 0.25%) and an untreated control were included for comparison. Results revealed that neem leaf powder was the most effective, achieving the highest adult insect mortality and the lowest adult emergence. In contrast, Lantana powder exhibited the least efficacy, allowing 94.38% more adult insects to emerge compared to neem powder. Untreated grains experienced a 20% weight loss due to rice weevil infestation after one month of storage, whereas treatment with 5% neem leaf powder reduced weight loss to a mere 0.14%. This reduction was statistically significant compared to all other treatments. These findings suggest that neem leaf powder at 5% is a highly effective, eco-friendly, and safe alternative to chemical insecticides for controlling rice weevils in stored grains.

Tasks: development of a recipe for a bakery product with blackcurrant powder for shock freezing; development of technology for the production of a bakery product with blackcurrant powder; assessment of organoleptic and physico-chemical indicators of the quality of the finished product. The objects of study are bakery products, blackcurrant, semi-finished products and finished bakery products with the addition of blackcurrant powder, subjected to shock freezing. The research of bakery products was carried out in laboratory conditions of the department "Technologies of bakery, confectionery and pasta production" of FSBEI HE "Krasnoyarsk State Agrarian University" at the Institute of Food Production. In the laboratories of the department, 2 types of bakery products were prepared with the addition of blackcurrant powder and a control sample for comparative evaluation in triplicate. Further studies were carried out on products after the application of shock freezing technology. Black currant powder was used obtained by convection drying, packaged in a sterile container under aseptic conditions. A recipe and technology were developed using shock freezing of a bakery product with blackcurrant powder in order to extend the shelf life of the semi-finished product and facilitate its transportation to the places of preparation of products with an incomplete production cycle without loss of product quality. The quality of the bun was assessed by organoleptic and physico-chemical parameters. In the course of the study, the variant with the addition of 2 % blackcurrant powder was chosen as the best sample, since this sample has the best organoleptic characteristics and corresponds to the physicochemical parameters according to the regulatory documentation. The mass fraction of moisture in the developed product was 39 %, acidity – 2.6 degrees, porosity – 73 %. These indicators are included in the allowable range according to GOST 6649-53.

The experiment was carried out in the Teaching and Research Farm of the Department of Animal Science, Faculty of Agriculture Usmanu Danfodiyo University, Sokoto, Nigeria, to determine the effects of dietary oregano leaf powder on meat quality of broiler meat. The diets were supplemented with oregano leaf powder at 15g/kg, 20g/kg, 25g/kg and 0g/kg (control group), represented as TI, T2, T3 and T4, respectively, dietary oregano leaf powder did not affect muscle pH a* values of broiler meat (P>0.05). However, oregano leaf powder significantly affected b* value, water holding capacity, drip and cooking losses. Higher inclusion level (25g) of oregano leaf powder improves meat quality parameters while supplementation of up to 15g did not affect most of the meat quality parameters. The study recommended 25g inclusion levels of oregano leaf powder due to the positive effects on meat quality parameters of broiler chicken meat. Further studies on the mode of action of oregano leaf powder using different species of poultry on meat quality may be commercially interesting.

The energy level of the three diets, respectively, was 3015, 3081, 3210 kcol / kg, and the protein level was 23.11, 21.51. 19.58 The one-day old chicks were randomly divided into 6 treatments with 4 replications 15 chicks each. The treatments were T1 the control (standard diet), T2 ration with okra seed powder 5 g/Kg feed, T3 was okra seed powder by 10 g/Kg feed, T4 was with okra fruit powder by 5 g/Kg feed, T5 was okra fruit powder at 10 g/Kg of feed, and T6 ration with 5 g seed powder + 5 g of fruit powder. Findings showed that the okra seeds and fruit powder effectively increased chicks’ body weight, especially when using 10 g/Kg of the seeds powder with the diet, or when using 10 gm of the equal proportion of the fruit powder with the seed powder in the diet. Okra fruit powder was better in weight gain than okra seed powder. On the other hand, the use of a diet fortified with powdered okra fruits and seeds was effective in improving the rate of feed consumption in chicks during the experimental period.

Résumé :

Laboratory studies were conducted to investigate the repellency effect of six plant species (Azadirachta indica, Caralluma fimbriata, Allium sativum, Curcuma longa, Citrullus colocynthis and Calotropis procera) against Sitophilus zeamais reared on maize grains (Cv. Azam White) in the Laboratory of Entomology Department, Gomal University, Dera Ismail Khan, Pakistan. Six concentrations viz. 5000, 10000, 15000, 20000, 25000 and 30000 ppm of each plant powder were applied to 20 g of sterilized maize grains under constant conditions of 27 ± 1°C and 65 ± 5% relative humidity. Twenty newly emerged adult maize weevil were introduced into glass petri dishes and percent repellency of plant powders was determined. A. indica seed powder at 30,000 concentration showed 100% repellency against maize weevil followed by C. longa (76%) after 72 h exposure period whereas C. procera was found least effective showing only 39% repellency of the test insects compared to control. The powders of A. sativum, C. fimbriata were found moderately repellent against the test insects. During the observations, it was also noted that repellency of the tested plant powders was dose dependent, the higher the concentration of the tested powders, the higher was the repellency and vice versa. The findings of this study indicated that the selected plant products could be used for a safer control of maize weevil.

Résumé :

This study aims to evaluate the effect of Moringa leaf powder (Moringa oleifera L) in the diet on the performance of quail egg production. This research was conducted for 8 weeks at the Commercial Zone Animal Laboratory, Department of Animal Science, Faculty of Agriculture, Bengkulu University. The experimental design used in this study was a completely randomized design with 5 treatments with 5 replications and each replication consisted of 5 quails. The treatment given was P0 as a control; P1 ration contained 0.5% commercial feed supplement; P2 ration contained 0.5% Moringa leaf powder; P3 ration contained 1.5% Moringa leaf powder; P4 ration contained 2.5% Moringa leaf powder. The results showed that the Moringa leaf powder in rations up to a level of 2.5% had no significant effect (P0.05) on feed intake, egg weight, egg production, egg mass production, and feed conversion ratio. Based on the results of the study, it was concluded that the administration of 0.5% Moringa leaf powder could replace commercial feed supplements. The higher levels of Moringa leaf powder administration did not improve egg production performance. The addition of commercial feed supplement in quail rations was not necessary.

Résumé :

The short description of the new approach to the pneumatic powder injection process analysis was presented in the article. The experiments with the high speed camera recording of the two-phase jet in pneumatic powder injection process were carried out in the Department of Foundry, Silesian University of Technology, Poland. The results were briefly analyzed and some interesting conclusions appeared, especially that the real velocity of the injected particles is far less than it is normally calculated with use of the well-known formulas. They were compared with existing literature data as well as with some experimentspreviously made by authors. Powder particles velocity and two-phase jet mass concentration were analyzed as the most important parameters for powder injection process. The results described are part of the complex experimental plan and the next step is computer modeling (just launched) of the jet introducing liquid.

The paper presents the results of model experiments with new lance design. The lance was invented in Silesian University of Technology, Department of Foundry. It is dedicated for the pneumatic powder injection into liquid metal bath without lance submersion. The situation like that is common for small molten alloy volume when the problem of temperature decrease is significant. In such case the carrier gas introduction into metal as well as cooling with gas blowing onto metal bath surface should be avoided. The new lance was equipped with four parallel slots made on its outlet and a flange. This design causes the carrier gas evacuation before it reaches the molten metal surface. The article presents the model experiments made with use of the device for the diphase gas-powder jet forces recording. The comparison of two lances: normal steel pipe and this of new design was presented in the article, too.

Résumé :

The almond moth Cadra cautella (Walker) is a notable stored product pest which can cause detrimental loss on stored cocoa. Cocoa can be stored in bean and powder forms. The information about survival and development of C. cautella on stored cocoa is limited. This research aimed to determine the effect of cocoa powder and cocoa bean in the storage against the survival and development of C. cautella. This research was conducted in Plant Pests Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, Universitas Brawijaya. This research consisted of two treatments namely cocoa bean and cocoa powder with no choice method and repeated six times. The observed variables were number of larvae, pupae, male and female almond moth of F1 progeny, and developmental time of this insect. The t-test analysis was applied to determine the treatment effect. Results showed that the number of larvae, pupae, adult males and females of F1 progeny cultured on cocoa powder were significantly higher than on cocoa bean. The total developmental time and life cycle of almond moth were shorter on cocoa powder than on cocoa bean. Therefore, to store cocoa in powder form is riskier to the almond moth infestation rather than in bean form. Hence, it is suggested to take more concern on the cocoa powder storage better in order to minimize the almond moth infestation.

Résumé :

We evaluated the efficacy and safety of stir-fried white pepper in the treatment of infant and children diarrhea. This was a randomized trial conducted in the pediatric emergency department of the hospital affiliated to Jining Medical College. One hundred seventy four patients were selected from outpatients from 2011 to 2012. Participants were randomly assigned to treatment with stir-fried white pepper (n = 88) or montmorillonite powder (n = 86). The proportions of chronic diarrhea patients (n = 52) showing success of treatment were similar for both groups. There were great differences between the two groups in acute diarrhea (n = 62) and persistent diarrhea (n = 60), and the cure rate of stir-fried white pepper was higher than montmorillonite powder in both groups. The prescription of stir-fried white pepper significantly decreased the frequency of diarrhea in infants and children under 2.5 years with diarrhea compared to treatment with montmorillonite powder, especially for the patients with acute diarrhea or persistent diarrhea.
