“…Para WSI, sólo MC en su término cuadrático tuvo un efecto significativo negativo (p<0.05); menor MC podría haber incrementado la fuerza de arrastre en el dado de salida, resultando en un almidón más gelatinizado. Para H, ambos términos cuadráticos de T y MC mostraron efectos significativos negativos (p<0.05); el decremento en H con un incremento de T podría deberse a mayores expansiones a temperaturas elevadas (12). Además, un incremento en MC disminuye la expansión lateral debido a la plastificación de la masa fundida (19).…”

Objective: To evaluate the physicochemical properties of an extruded feed using bean (Phaseolus vulgaris L.) as a soymeal substitute and to perform pig growth trials, evaluating nitrogen digestibility. Materials and methods: This research was divided into two stages, the first one consisted on the standardization of the extruded feed, where two formulations of bean flour (Pinto Saltillo variety), cornflour (Cafime variety), and soybean meal were evaluated: 20/67/13% and 30/60/10%, respectively. Samples were processed in a single screw extruder at 120-150°C and moisture content of 18-22%. Evaluated physicochemical properties were: expansion index, bulk density, water absorption index, water solubility index, hardness, water activity and color parameters: L*(clarity), a*(red-green chromaticity) and b* (yellow/blue chromaticity). In the second stage, the in vitro dry matter digestibility and fecal apparent digestibility were evaluated using the optimal treatment obtained from stage 1. Results: Optimal conditions for the 20% of bean flour formulation were: Temperature of 124.4°C and moisture content of 18.59%. Extrusion temperature decreased bulk density, hardness, and water activity, but increased L* and expansion index. Moisture content decreased bulk density, water activity, hardness, and a*. In vitro dry matter digestibility was higher for the extruded bean diet in comparison to the control diet (92.33% vs. 85.33%). Conclusions: Results indicated that bean flour is a viable option for animal consumption in terms of nutritional value and good digestibility.

“…Several authors have recently investigated the effect of CSP, CSF, CSC and CSPI on feed diets in aquacultural species (Anderson et al, 2016;Wang et al, 2020;Ye et al, 2020;Yin et al, 2018), pigs , and lambs (Moretti et al, 2019). Delgado et al, (2021) studied the functional properties of the extruded shrimp feed containing CSM with ultra-low gossypol content. It was concluded that use of ultra-low gossypol CSM as fishmeal substitute is a feasible alternative to reduce the costs of the shrimp feed while showing a balanced content of minerals, amino acids, protein, and essential fatty acids.…”

“…Reyes-Jáquez et al [ 24 , 25 ] formulated and evaluated Gl-meal/corn flour snacks by extrusion cooking. Shrimp feed with Gl cottonseed meal as a protein source was made by extrusion and its structural, rheological and calorimetric properties evaluated, showing the Gl meal-based shrimp feed is a reasonable option to decrease feeding costs [ 26 , 27 ]. Specifically, Gl cottonseed protein could replace up to 75% fishmeal protein in the diet of southern flounder without compromising its growth potential [ 28 ].…”

Common “glanded” (Gd) cottonseeds contain the toxic compound gossypol that restricts human consumption of the derived products. The “glandless” (Gl) cottonseeds of a new cotton variety, in contrast, show a trace gossypol content, indicating the great potential of cottonseed for agro-food applications. This work comparatively evaluated the chemical composition and thermogravimetric behaviors of the two types of cottonseed kernels. In contrast to the high gossypol content (3.75 g kg−1) observed in Gd kernels, the gossypol level detected in Gl kernels was only 0.06 g kg−1, meeting the FDA’s criteria as human food. While the gossypol gland dots in Gd kernels were visually observed, scanning electron microcopy was not able to distinguish the microstructural difference between ground Gd and Gl samples. Chemical analysis and Fourier transform infrared (FTIR) spectroscopy showed that Gl kernels and Gd kernels had similar chemical components and mineral contents, but the former was slightly higher in protein, starch, and phosphorus contents. Thermogravimetric (TG) processes of both kernels and their residues after hexane and ethanol extraction were based on three stages of drying, de-volatilization, and char formation. TG-FTIR analysis revealed apparent spectral differences between Gd and Gl samples, as well as between raw and extracted cottonseed kernel samples, indicating that some components in Gd kernels were more susceptible to thermal decomposition than Gl kernels. The TG and TG-FTIR observations suggested that the Gl kernels could be heat treated (e.g., frying and roasting) at an optimal temperature of 140–150 °C for food applications. On the other hand, optimal pyrolysis temperatures would be much higher (350–500 °C) for Gd cottonseed and its defatted residues for non-food bio-oil and biochar production. The findings from this research enhance the potential utilization of Gd and Gl cottonseed kernels for food applications.
