Soybean proteins are added in a predetermined amount to the ground fish meat (surimi), and the mixture is kneaded, compressed, heated, and is molded into a sheet by a twin-screw extruder. The sheet-like mixture is then cut into flakes, followed by frying, to efficiently produce fish-containing snack that exhibits crunch feeling like that of potato chips, that is rich in proteins, and that tastes good.

Process for preparing fish-containing snack food

A product obtained by subjecting an isolated soybean protein and corn starch used as the raw materials to pressing and heating treatments in a twin-screw extruder exhibits its fibrous properties when it is immersed in warm water to dissolve out a part of the corn starch and a little amount of the soybean protein. This product is relatively tough. The corn starch is dissolved out in only a small amount upon the immersion in warm water and, therefore, the yield is high.

Process for producing vegetable protein foods

Two kinds of hydrolyzed protein having different characteristics respectively are obtained by hydrolyzing soy protein with protease and separating the mixture of hydrolyzed products using their solubilities in a 5% trichloro acetic acid aqueous solution as the guidance of the separation. The hydrolyzed protein of the low solubility possesses excellent emulsifying properties, and the one of the high solubility possesses excellent foaming properties.

Process for preparing hydrolyzed products of soy protein

A process for producing a bean cake which comprises feeding whole or hulled grains of beans to a twin-screw extruder, extruding the beans through the twin-screw extruder at a temperature in the range of 90.degree. to 250.degree. C. to form a cake, and while extruding, adjusting the moisture content of the beans to be treated to the range of 8 to 50 weight percent and swelling the starch component while texturizing the protein component of the beans.

Disclosure is made of a process for the production of soya protein flakes having similar structure and taste to fish flakes of tuna and the like, comprising soya protein-water mixture to an extrusion process under heat and pressure by using an extruder having at least first and second dies each having at least one opening, the distance between the dies being 2-6 mm, the gap between rims of nearest openings of the dies being greater than or equal to the cross-sectional diameter of the opening of the first die.

Retort salad having improved emulsification heat stability can be produced by using mayonnaise-like food containing a partial hydrolyzate of an alcohol-denatured soybean protein with protease as an emulsifier.
