Abstract:
Background: High cyanide varieties of cassava must be detoxified before consumption. Several studies showed detoxification of cassava by slicing, submerged fermentation (soaking), solid state fermentation, and drying. One of traditional detoxification is combination of submerged and solid state fermentation and the effect of this processing on cyanide reduction and food properties has not been evaluation yet. Objective: This research studied the effect of solid state fermentation time on physicochemical, starch granule morphology, and in vitro starch digestibility of cassava flour from high cyanide varieties of Malang 4, Malang 6, and Sembung. Methods: Three varieties of high cyanide grated cassavas were soaked for 3 days in ratio of water to cassava 1:1. After draining for 1 hour, grated cassava was placed in a bamboo container and put in a humid place for 3-day solid state fermentation. Fermented grated cassavas were then dried, milled, and analyzed. Results: Solid state fermentation similarly affected cyanide reduction and characteristics of cassava flour for three high cyanide varieties. The detoxification process reduced cyanide to 89.70-93.42% and produced flour with a total cyanide of 8.25-10.89 mg HCN eq/kg dry matters, which is safe to consume. Fermentation decreased cyanide, starch content, titratable acidity, swelling power, and solubility; meanwhile pH, amylose content, water absorption, oil absorption, and in vitro starch digestibility increased in all three varieties studied. Submerged fermentation reduced the pH thus inhibiting the degradation of linamarin and cyanohydrin into free HCN. pH value was increased by solid state fermentation, from 4.43 to 6.90 that optimum for linamarin and cyanohydrin degradation into free HCN. The submerged and solid-state fermentation indeuce spontaneous microbial growth that affected chemical composition of cassava flour. The changes of structure and morphology of starch granules affected pasting properties, and Increased in vitro starch digestibility due to damaged granules. Conclusion: Solid-state fermentation reduced cyanide content of all three cassava varieties into the safe level for consumption, and aiso changed chemical, physical, and functional characteristics and starch digestibility of cassava flour.

Abstract:
Starch nutritional fractions as well as thermal properties and other analysis are essential for food and industrial application. Cassava bagasse is an important agro-industrial residue and its starch content was evaluated using two alternative methods. Thermal characterization and microscopy analyses helped to understand how hydrolysis digests starchy fraction of cassava bagasse. The melting point of cassava starch occurred at 169.2ºC. Regarding TG analyses, after moisture content, there were observed two main mass losses for all samples. Results suggest hydrolysis carried out using enzyme is less effective in order to convert total starch content in cassava bagasse. However, using sulfuric acid, fibers are affected by analyses conditions.

Abstract:
This work aimed to determine the physicochemical and functional properties of starch cassava grown in two different locations in Sabah, namely Tawau and Semporna. In this study, the starch of the cassava was extracted using a wet method and analysed for its physicochemical and functional properties. The total starch content of cassava grown in Semporna showed a higher value (61.21 g/100 g) compared to the sample from Tawau (51.77 g/100 g). No significant difference (p>0.05) observed for starch yield extracted from these two locations. However, there was a significant difference (p<0.05) showed for total starch, resistant starch and amylose content. The amylose content of starch isolated from Semporna (23.16%) was higher than from Tawau (13.87%). Scanning electron microscope revealed that starch isolated from both locations had smooth surfaces with some granules spherical, elongated and irregular in shape. Cassava starch from Semporna exhibited a high value of swelling power (6.85%) compared to Tawau (4.07%), and they were significantly different (p<0.05). The solubility values of the starch samples from Tawau and Semporna were 28.48% and 24.34%, respectively. The pH was observed to be lower for cassava starch isolated from Tawau (4.80) than for starch obtained from Semporna (5.49). The water absorption capacity of starch from Semporna absorbed slightly more water than starch from Tawau, with values of 76.51% and 63.64%, respectively. Pasting properties results showed no significance for all profiles measured except for setback viscosity. No significant differences (p>0.05) were observed for all gelatinisation and retrogradation properties. This study suggests that location influenced the physical, chemical and functional properties of cassava’s starch.

Abstract:
Fermented cassava starch is one of modified cassava starch products and used in many countries in several food products. The fresh extracted cassava starch is modified by a process of fermentation and sun drying by means the traditional methods. Several works have shown that fermentative process alters the starch granule, giving fermented starch its characteristics are different from those of the native cassava starch. The main difference between fermented cassava starch[A1] and native cassava starch reside in the expansion property. Understanding the transformation of physico-chemical properties of cassava starch during fermentation is important for controlling the production processes. This discourse refers to the several works that intend to chemically show the expansion property of fermented cassava starch, considered a chemically and enzymatically modified product, with acidic characteristics, perforated granules and high expansion capacity. Expansion is a natural characteristic of fermented cassava starch, defined as the growth rate of the dough during oven cooking, also referred to as expansion rate. The main aim of this discourse is to get a better understanding how to manage the production processes in order to achieve greater consistency in the quality of sour cassava starch.Â

Abstract:
The kinetics and inhibitory effects of cyanide on the granular starch hydrolyzing enzyme (GSHE) activity during hydrolysis of cassava (Manihot esculenta Crantz) starch at low temperature were studied. The substrates included native cassava starch at various concentrations (100-400 g/L) and native cassava starches with added cyanide at various concentrations (50-150 mg/kg), while the concentration of enzyme was 1.5% (w/w). A decrease in reducing sugar concentration during hydrolysis of cassava starch indicated that the cyanide reduced the enzyme activity. Lineweaver-Burk plot of Michaelis-Menten equation was used to study the inhibition kinetics. The maximum velocity (Vmax) value was higher for native cassava starch than that of native cassava starch with added cyanides. The presence of cyanide was found to reduce the Vmax values. No significant different of the saturation constant (Km) value between native cassava starch and native cassava starch with added cyanides was observed. Based on the inhibition type analysis, the effect of cyanide in the cassava starch can be classified as a noncompetitive inhibition, with the Ki value of 0.33 mg/L.

Abstract:
Cassava is a high potential feedstock for bioethanol production in Asian countries, primarily due to high yield of carbohydrate per unit land, and its ability to grow on marginal lands with minimal agrochemical requirements. The objective of this study was to compare the bioethanol production from cassava starch with corn starch using a conventional and a raw/granular starch hydrolyzing process (GSH). The fermentation performance of cassava starch was compared with three corn starch types with different amylose: Amylopectin ratios. The final ethanol concentration with cassava starch was similar to that of two corn starch types, dent corn and waxy corn for both processes. For the cassava starch, the ethanol concentration achieved with GSH process was 2.8% higher than that in the conventional process. Cassava starch yielded the highest fermentation rates of the four starches investigated, during the conventional process. Ethanol production and fermentation profiles comparable with corn, a widely used feedstock, makes cassava starch an attractive substrate for bioethanol production.

Abstract:
In Ghana, cassava is a marginalized crop in food policies due to low research attention given it. However, high starch in cassava root is an important characteristic that makes the crop a potential industrial cash crop. In light of this, the Government of Ghana in 2001 introduced the Presidential Special Initiative (PSI) on Cassava, which aimed at industrializing the cassava sector for job creation and livelihood improvement through starch extraction. One of the import industrial products from cassava starch is ethanol. Ethanol is reported as the largest opportunity for cassava industrialization in Ghana followed by food-grade starch. However, the local ethanol consuming industry, Kasapreko, operates by importing over 25 million litres of ethanol every year due to inadequate supply of ethanol from local starch factories. This situation exists because of lack of cassava varieties that can yield more starch (75% or more) per total dry weight to feed the starch factories for sustainable production. Therefore, this review explores the relevance of developing high starch yielding cassava to the industrialization of the cassava sector in Ghana and lessons to learn from the success story of Thailand, the country with the world’s most industrialized cassava sector.

Abstract:
Calcium can affect in vitro cassava storage roots formation and starch accumulation. Low concentration of calcium stimulates to induce in vitro cassava storage roots formation and the accumulation of starches. With the addition of calcium concentration, the diameter of the in vitro cassava storage roots was increased, but the induction rate and starch content was decreased. The scanning electron microscope observations SC124 in vitro cassava storage roots starch and field cultivation of cassava root starch, starch grains formed by these two different ways is very similar in size and shape. Our findings show that, apply tissue culture techniques to study the cassava starch synthesis mechanism is feasible.
