Extruded grain granules in liquid granule mixed sterilization product and preparation method thereof

Abstract

The invention discloses extruded cereal particles in a liquid particle mixed sterilization product and a preparation method of the extruded cereal particles. The extruded cereal particles are prepared by extruding the following raw materials in parts by weight through a screw rod extruder: 100 parts of cereals, 1.6-50 parts of hydrophilic colloid and 0-25 parts of a food ingredient, wherein the hydrophilic colloid comprises 0.4-1.4 parts of xanthan gum, 1-2.5 parts of sodium carboxymethylcellulose, 0.2-1.2 parts of gellan gum and 0-44.9 parts of selective hydrophilic colloid; and the selective hydrophilic colloid is one or any match of more of artamisia sphaerocephala krasch gum, sodium alginate, curdlan gum, fenugreek gum, locust bean gum, guar gum, gelatin, carrageenan, Arabic gum, konjac glucomannan, sodium polyacrylate, propylene glycol alginate, modified starch and plant protein powder. The extruded cereal particles can bear sterilization, and are not scattered and excessively gelatinized after being immersed for a long time; and the production period is short and the production cost is low, and the food ingredient can be added in a relatively wide range.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to extruded grain particles in a liquid particle mixed sterilization product, and also relates to a preparation method of the extruded grain particle in the liquid particle mixed sterilization product. Background technique [0002] In recent years, liquid granule products have become the main development direction of the dairy and beverage industries. There are already a variety of granule-containing liquid products in the Chinese domestic market, such as Yili's "Grains" and so on. new growth point. [0003] Cereals, including cereals, beans and potatoes, are the main and most economical source of heat for the human body. Grains are rich in complex carbohydrates, which can provide "prime energy", which is conducive to balanced nutrition and high digestibility. Grains are rich in cellulose, which is beneficial to improve intestinal function, lower blood choleste...

AI Technical Summary

Problems solved by technology

[0009] Secondly, the UHT sterilizer has strict requirements on the particle size, which usually needs to be controlled within 4-6 mm, which directly leads to the unusability of most natural grains, and the types of raw materials are limited

If the natural grains are crushed to an appropriate size and directly added to the liquid feed liquid for sterilization, although the requirements of the sterilization process are met, the excessive gelatinization will be exacerbated due to the destruction of the natural structure of the grains

[0010] Again, even natural grains from the same source and in the same batch have differences in size, shape, integrity, intrinsic quality, etc., making it difficult to ensure uniformity, resulting in product uneven quality

In addition, adding natural grain particles to UHT milk makes it impossible to freely add other food ingredients, and it is difficult to carry out nutritional compounding and fortification, which limits the expansion of product categories
