preparation example Construction

[0024] The first aspect of the present disclosure provides a method for preparing additive-free whole cotyledon soymilk, the method comprising the following steps:

[0025] S1. Cleaning and removing impurities from the bean raw materials to obtain pure beans, soaking the pure beans in demineralized water to obtain soaked beans;

[0026] S2, subjecting the soaked beans to inactivation treatment and peeling treatment to obtain watercress;

[0027] S3. Roughly grinding the bean paste to obtain a first bean paste, and finely grinding the first bean paste to obtain a second bean paste; the particle size D90 of the first bean paste is below 1000 μm, and the second bean paste is The particle size D90 of the two bean paste is below 150 μm;

[0028] S4. Degassing and first homogenizing the second soybean paste to obtain soybean milk puree; the particle size of D90 in the soybean milk puree is 30-80 μm;

[0029] S5. The soybean milk puree is adjusted to a constant volume and then ster...

Embodiment 1

[0044] This embodiment provides a kind of whole cotyledons soybean milk, and this soybean milk is prepared by the following steps:

[0045] (1) Wash and remove impurities from the bean raw materials to obtain pure beans. The specific operation steps are: 14 parts of soybeans are removed by a cleaning machine to remove surface dust, stones, metals and bad bean residues to obtain clean soybeans.

[0046] (2) Soaking: Put the soybeans into a soaking bean tank, the ratio of soybeans to water is 1:3, the water temperature is 20°C, and soak for 12 hours.

[0047](3) The soaked beans are subjected to enzyme-inactivating treatment and peeling treatment to obtain watercress. The conditions for enzyme-inactivating treatment are: 95° C., blanching with 3 times of water for 15 minutes.

[0048] (4) The first bean paste is obtained by coarsely grinding the watercress. The conditions for coarse grinding are as follows: using a ceramic mill, grinding at a soybean-to-water ratio of 1:4 and ho...

Embodiment 2

[0056] This embodiment provides a kind of whole cotyledons soybean milk, and this soybean milk is prepared by the following steps:

[0057] (1) Wash and remove impurities from the bean raw materials to obtain pure beans. The specific operation steps are: 7 parts of soybeans are removed by a cleaning machine to remove surface dust, stones, metals and bad bean residues to obtain clean soybeans.

[0058] (2) Soaking: Put the soybeans into the soaking bean tank, the ratio of soybeans to water is 1:3, the water temperature is 15°C, the relative vacuum is -0.03MPa, and soak for 10 hours.

[0059] (3) The soaked beans are subjected to enzyme-inactivating treatment and peeling treatment to obtain watercress. The conditions for enzyme-inactivating treatment are: 95° C., blanching with 3 times of water for 15 minutes.

[0060] (4) The first bean paste is obtained by coarsely grinding the watercress. The conditions for coarse grinding are as follows: using a ceramic mill, grinding at a s...

Abstract

The invention relates to a preparation method of additive-free whole cotyledon soymilk. The method comprises the following steps: S1, cleaning bean raw materials, removing impurities to obtain pure beans, and soaking the pure beans with softened water to obtain soaked beans; s2, performing enzyme deactivation treatment and peeling treatment on the soaked beans to obtain bean halves; s3, performing coarse grinding treatment on the bean halves to obtain first bean paste, and performing fine grinding treatment on the first bean paste to obtain second bean paste, wherein the particle size D90 of the first bean paste is 1000 [mu] m or less, and the particle size D90 of the second bean paste is 150 [mu] m or less; s4, performing degassing treatment and first homogenization treatment on the second bean paste to obtain soymilk primary pulp, wherein the particle size of D90 in the soymilk primary pulp is 30-80 [mu] m; and S5, blending the soymilk raw stock to a constant volume, and then performing sterilization treatment. The soymilk prepared by the method is good in flavor and smooth in mouth feel, and all nutritional ingredients of the soybean cotyledons are reserved.

Description

technical field [0001] The present application relates to the field of food science, in particular to an additive-free whole cotyledon soybean milk and a preparation method thereof. Background technique [0002] Soymilk is a product of traditional Chinese soymilk industrialization. Its main processes include ① raw pulping process: soaking soybeans and refining, separating pulp and residue, boiling, blending, homogenizing, and sterilizing filling; ② cooked pulping process: soaking soybeans and then refining , pulp cooking, separation of pulp and residue, blending, homogenization, sterilization and filling. There are differences between the two processes in boiling pulp and separating pulp and dregs, but they both need to separate bean dregs. According to the existing data, the wet okara produced after 1 kg of soybean defibrination is 0.8-1.2 kg, and the water content is 75-85%. With the increasing pressure of environmental protection, the treatment of these bean dregs is a ...
