Abstract

The invention belongs to the technical field of food and mainly relates to a method of utilizing soybean aqueous enzymatic method hydrolysate and residue to prepare Qianye tofu. The method includes following steps: adopting an aqueous enzymatic method to extract soybean to obtain free oil, emulsion, hydrolysate and residue; spray-drying the hydrolysate to obtain aqueous enzymatic method soybean protein; homogenizing ice water, the aqueous enzymatic method soybean protein and the aqueous enzymatic method residue, adding soybean oil, glutamine transaminase, tapioca modified starch, edible salt, gourmet powder and white sugar, mixing, and pulping to obtain paste; scraping the surface of the paste to be flat; putting in a disc, freezing at high pressure to obtain a formed product, dicing, and freeze-storing at normal pressure to obtain Qianye tofu. High-pressure freezing technology is utilized, so that compared with Qianye tofu produced by conventional processing modes, ice crystals formed by freezing are small in size and uniform in distribution in the Qianye tofu, water loss is small, and quality and taste of the Qianye tofu are improved effectively.

Description

technical field

[0001] The invention discloses a method for preparing thousand-sheet bean curd by utilizing soybean water enzymatic hydrolyzate and residue, and belongs to the technical field of soybean product processing. Background technique

[0002] Aqueous enzymatic method is a new way of extracting oil from oil plants by using the water phase containing biological enzymes as the extraction medium. Aqueous enzymatic method, as a green and environment-friendly oil extraction method, has received extensive attention. In the process of extracting oil by aqueous enzymatic method, four parts will be produced: free oil, emulsion, hydrolyzate and residue. Hydrolyzate and residue are the by-products of the water enzymatic method, which are rich in protein, sugar and dietary fiber, but there are few studies on it at this stage, and the degree of commercialization is also low.
