Abstract A new process for the preparation of soybean protein concentrate (SPC) by directly extracting full-fat soy flour with a mixture of hexane and aqueous ethanol was established. Compared with conventional methods, it has some advantages, such as saving energy and reducing protein denaturation caused by heat action during solvent recovery, because this process saves one step of solvent recovery. The effects of aqueous ethanol concentration and the mixure ratio (hexane to ethanol) on the degree of protein denaturation and product quality were investigated, on the basis of which the orthogonal tests were performed. The optimum technical parameters were obtained by analyzing the results of the orthogonal tests with statistical methods. We found that SPC can be obtained by extracting full-fat soy flour under the following conditions: mixture ratio hexane: 90% ethanol, 9:1, v/v; extraction temperature, 45°C; ratio of solid to solvents, (1:2 w/v); and 5 repeated extractions (15 min each time). The results of quality analysis showed that solubility of the product was improved significantly [nitrogen solubility index (NSI) 46.6%] compared with that for ethanol washing of protein concentrate (NSI 8.7%).

Soybean Protein Concentrate

Textured soybean protein (TSP) is a product made from cooking and extrusion of soybean protein, which has been widely used in food, feed and other industries. This text made soybean protein isolated (SPI) and soybean protein concentrate (SPC) as the raw materials to produce filamentous protein production. By experiment, the influence of puffing temperature, screw speed and feed rate on the quality of the protein products was studied. Finally it was concluded that when the temperature of the barrel was 152 °C, the screw rotation speed was 119 rpm, the feed rate was 0.426 kg/min, the TSP product had the biggest expansion degree.

Milk Replacers

Two experiments were carried out with Holstein heifer calves to determine the effect of supplying a major portion of the protein in milk replacers by isopropanol-extracted protein concentrate from whole herring (FPC) or a mixture of FPC and soybean protein concentrate (SPC). Milk replacers were compared with whole milk in experiment 1. All calves were abruptly weaned when consuming 0.5 kg starter/day, or by 5 weeks of age. Calf performance was similar when the pre-weaning liquid diet was whole milk, or milk replacers containing either milk protein or 50% of the protein from FPC. Average daily gains to weaning and to 26 weeks of age for all calves were 377 and 692 g/day, respectively. Calves in experiment 2 were fed either an all-milk protein milk replacer or one containing 98% of the protein equally from FPC and SPC. Both milk replacers were fed once daily either six or seven times per week. Calf growth to weaning was lower on the FPC–SPC formula (283 vs. 364 g/day, P < 0.01), but was not significantly different (P < 0.05) to 15 weeks of age (618 vs. 643 g/day). Feeding milk replacer six vs. seven times per week had no significant effect on calf growth. Digestibility coefficients of dry matter, nitrogen, and energy were similar in bull calves fed the all-milk or FPC–SPC protein milk replacers, but retention of absorbed nitrogen was less on the latter diet (54 vs. 45%, P < 0.10).
