Optimization using response surface methodology of the soaking and germination time of two rice varieties (Nerica 3 and Nerica L56) grown in the locality of Dschang (West-Cameroon)

Effect of variety and malting conditions on proteolytic activity, free amino nitrogen, and soluble protein contents of two maize varieties (Atp-Y and Coca-sr): amylolytic activity and physico-chemical and functional properties of optimal sample

“…Temperature plays a role in the activation and formation of binding energies. In the context of this study, it favors the lifting of the dormant state of the grains by facilitating the absorption of water in particular ( 43 ). The responses gradually evolve with the soaking temperature to maxima before lowering.…”

“…On the other hand, a positive effect of the soaking time, the quadratic effect of the ripening time, the interactions between input concentration and germination time, soaking temperature and germination time, and finally germination time and ripening time are observed. The observed difference in the action of the factors as well as their direction of variation on the two varieties would be the effect of the pectocellulosic and nutritional composition of the two varieties ( 43 ). It follows that a 2-fold increase in germination and maturation times for the Coca-sr variety would result in the use of free amino acids from catabolism for the production of energy needed for anabolism.…”

“…Some parameters such as determination coefficient ( R 2 ), the adjusted coefficient of determination ( R 2 adj), the absolute average deviation analysis (AADM), and the bias factor (bf) are used to check the robustness of the model, the adequacy between the predicted and experimental models, and the degree of concordance between the selected variables and the evaluated responses ( 43 , 53 ). The R 2 and adj R 2 ranged from 82.99 to 90.53% and 72.69 to 84.79%, respectively.…”

“…These parameters increase with time to an optimal value around 25 h of soaking followed by a non-significant effect on the different responses before a decrease in these. Klang et al (43) also reported that the amylolytic activity of the paddy rice varieties Nerica 3 and Nerica L56 was highest between 20 and 25 h soaking. They attributed this to an activation of the reserve enzymes and the facilitation of their mobility following the absorption of water by the grains.…”

Nutritional and Rheological Characterization of an Infant Flour Based on Parboiled Rice (Oryza sativa), Spirulina (Spirulina platensis), and Cashew Nut (Anacardium occidentale)

“…It appears that the R 2 of the different responses is greater than 75%, the AADM is equal to 0, and the Bf is between 0.75 and 1.25. Indeed, when these three coefficients respected standard values, we consider that there is an adequacy between the experimental responses and the predicted responses given by the model [16].…”
