Embodiment 1

[0036] This example provides an enzymatic hydrolysis mung bean product, which is a cereal pulp product with the following raw material composition (based on one ton product):

[0037] Enzymatic mung bean milk (mass ratio of mung bean powder to water is 35:65) 998.7 kg

[0038] Gellan gum 1.3 kg.

[0039] This product is produced through the following steps:

[0040] 1. Ingredients: Heat the ingredient water accounting for 50% of the ingredient amount (this ingredient amount refers to the ingredient amount in the process of enzymatically hydrolyzing the grain alone, that is, the water used to prepare the enzymatic mung bean milk) to 85°C, add the grain powder, and stir to make the grain The powder is evenly dissolved and dispersed to obtain a grain slurry.

[0041] 2. Keep the temperature of the grain slurry at 80°C, control the stirring speed at 100 rpm, add the high-temperature α-amylase to 0.9% of the total weight of the grain flour, keep it at a constant temperature, and ...

Embodiment 2

[0049] This embodiment provides an enzymatic hydrolysis oat milk product, which is a cereal pulp product, and has the following raw material composition (based on one ton of product):

[0050]

[0051] This product is produced through the following steps:

[0052] 1. Ingredients: Heat the ingredient water accounting for 50% of the ingredient amount (this ingredient amount refers to the ingredient amount in the process of enzymatically hydrolyzing the grain alone, that is, the water used to prepare the enzymatic oat pulp) to 83°C, add oat flour, and stir to make the oatmeal The powder is evenly dissolved and dispersed to obtain a thick oatmeal slurry.

[0053]2. Keep the temperature of the thick oat slurry at 83°C, control the stirring speed at 800 rpm, add high-temperature α-amylase, the amount of high-temperature α-amylase accounts for 1.5% of the total weight of the grain flour, and maintain a constant temperature. The viscosity of the product was detected every 10 minut...

Abstract

The invention relates to a grain pulp using high-temperature alpha-amylase and a preparation method thereof. The preparation method of the grain pulp using high-temperature alpha-amylase comprises the following steps: adding high-temperature alpha-amylase, and performing enzymatic hydrolysis. The invention provides a grain pulp product by using the above method. The provided preparation method comprises the following advantages that 1) material feeding time during a normal production can be saved, energy utilization efficiency is increased; and 2)starch enables full enzymatic hydrolysis under 80-85 DEG C by employing the high-temperature alpha-amylase, inactivation can be carried out under disinfection condition of 137 DEG / 4s, enzyme residue can not be generated, so that food safety can not be influenced.

Description

technical field [0001] The invention relates to a grain pulp product using high-temperature α-amylase and a preparation method thereof, belonging to the technical field of liquid food preparation. Background technique [0002] Grain is the main source of human energy, protein, B vitamins and minerals. Grain provides about 2 / 3 of human energy and protein, especially in developing countries. The current annual per capita grain consumption in developing countries is about 166kg. Major grains in the world include wheat, rice, and corn, while barley, sorghum, millet, oats, and rye are minor grains. During the development of human society, people’s understanding of the nutrition and health of grains has also gone through a long process of development. Grains are the most basic and main source of food for human beings. With the development of social economy, people’s consumption of grains has begun to increase. The pursuit of taste, flavor and appearance. [0003] my country is t...
