Selenium-enriched leisure instant bean product and preparation method thereof

Abstract

The invention discloses a selenium-enriched leisure instant bean product, which is prepared through the following steps of (1) stir-frying; (2) crushing; (3) steaming and boiling; (4) filtering; (5) curdling; (6) uncongealed tofu formation; (7) shaping; (8) primary marinating; (9) baking; (10) secondary marinating; (11) seasoning and packaging. Through the cooperated action of each steps, the selenium content of the bean product can be flexibly controlled to be in a range of 60 to 300mu g / kg; the intake quantity of the selenium element required by the human body in each day is met; the preparation method is simple; the raw materials can be easily obtained; the taste is unique; the market popularization is facilitated.

Description

technical field

[0001] The invention relates to an instant soybean product, in particular to a selenium-enriched leisure instant soybean product and a preparation method thereof. Background technique

[0002] According to "Historical Records", soybeans have been cultivated and eaten in China for more than a thousand years. And in today's society, soybeans are considered to be the main provider of high-quality vegetable protein. The protein content of soybean is as high as 40%, and it is also one of the oil crops. The oil content is about 20%. At the same time, soybean is rich in nutrients such as vitamins and minerals. In addition, soybeans also contain many biologically active substances, such as trypsin, phytic acid, soybean isoflavones and oligosaccharides, etc. Although the content of these substances is relatively low, they play a significant role in inhibiting cancer and other diseases. There are a variety of snack foods made from soybeans, but the current research h...
