Abstract

The present invention relates to preparation of one fat substitute. Microcrystal cellulose colloid (MCC) is viscous, smooth, thixotropic and like cream; and when used to replace fat in milk product, it can reduce the calorific value of milk product and increase the cellulose content. The MCC preparing method of the present invention includes first hydrolysis of cellulose into microcrystal cellulose and then colloidizing powdered microcrystal cellulose in one specific colloidizing equipment to obtain colloid. The colloidizing equipment consists of two discs, one fixed and one rotated, with flutes. When the rotating disc rotates at high speed, the microcrystal cellulose material through flutes between two discs is thrown to edge while is subjected to shearing force so as to be split into fine crystal particles as colloid.

Description

A kind of method for making of microcrystal cellulose colloid
The present invention relates to a kind of manufacture method of fat-replacer.
Along with the progress of society, the raising of people's living standard, the consumption of milk preparation is more and more higher, but the consequent is the fat of people's Excessive Intake and cause getting fat, adipopexis also can cause cardiovascular disorder simultaneously.As far back as the seventies, abroad just begin to attempt drink skim milk or seek fat-replacer.Shortcomings such as but the milk of sloughing fat has viscosity low, and mouthfeel is bad.Thereby never find suitable substitute.U.S. scientist is used for milk preparation with Microcrystalline Cellulose glue and can partly or entirely replaces fat wherein and keep original local flavor until the beginning of the nineties later stage eighties.This microcrystal cellulose colloid is that Mierocrystalline cellulose forms through hydrolysis and mechanical external force effect.Invent by U.S. scientist Battista (hundred for this tower) the sixties at first, progressively apply to the beginning of the nineties at the end of the eighties.The English full name of this colloidal is that MicrocrystallineCellulose Gel is called for short MCC glue, and its outward appearance resembles cream, is typical thixotropic fluid, to the insensitive suitable food-processing of temperature variation.The more important thing is according to modern medical theory, Mierocrystalline cellulose is the indispensable non-nutrient substance of human body, and it can prevent the disease such as the constipation of Digestive tract, intestinal obstruction etc., disease to cardiovascular systems also has regulating effect in addition, so it more and more is subjected to attention abroad.United States Patent (USP) (U.SPat., No.5,011,701) reported a kind of method of the MCC of manufacturing glue, the gel process of this method is to make fiber be cleaved into many tiny crystal grain to form colloid at last, its gel process be make Mierocrystalline cellulose aqueous systems (7.5%) under pressure at a high speed repeatedly by a device with slit, material has expanded effect in ejection makes Mierocrystalline cellulose tear into many tiny crystal grain to form colloid at last.Xiang Guan United States Patent (USP) also has U.SPat.NO.023 therewith, and 104; 011,701; 108,773 etc.
The invention provides a kind of method for preparing MCC glue by refined cotton linter, be characterized in realizing the gel process by collodier, the disk that collodier is close to mutually by two discs is formed, one of them disk is a fixed, another disk is rotary, disk is provided with opening for feed and discharge port, the contact surface of two disks is provided with groove, opening for feed is located at the top of fixed disc, discharge port is located at the below of rotary disk, groove between two disks on the contact surface is the radial distribution along disk, rotary disk connects the adjustable speed motor, when revolution, drive the disk high speed rotating, material enters fixed disc from the opening for feed above the disk and is full of two gaps between the disk, material outwards moves along groove from disk central authorities, the feed back that flows out from the disk gap circulates repeatedly to opening for feed, material is subjected to the effect of powerful shearing force during this period, cellulose grain is split into countless tiny crystal grain, these crystal grain have very big surface-area glassware for drinking water are had very big avidity, so viscosity of materials increases sharply and forms colloid, after viscosity of materials reaches certain requirement, draw from discharge port.Above-mentioned raw cellulose can be a refined cotton linter, also can be wood pulp or careless plasmoid.Hydrolysis can be with hydrochloric acid or sulfuric acid, and the concentration of acid is 0.2~4mol, and hydrolysis temperature can be 70~150 ℃, and the colloidal solid content is between 1~10%.
To be the viscosity that can make skimmed milk under the situation of 3% (amount of solid) in add-on bring up to 90cp from 10cp has improved mouthfeel and also increased cellulosic content simultaneously and be good for one's health for gel process of the present invention, the colloid MCC glue that obtains.
Embodiment one: refining linter pulp 100g, tear the 2000ml flask of packing into, and add 0.5mol hydrochloric acid 1000ml, be heated to 100 ℃ 3 hours, take out the acid of desalting of inclining, wash neutrality with water, concentration with 2% is sent into collodier, and obtaining viscosity is the creamy white colloid of 3000cp.Embodiment two: refining linter pulp 100g tears the 2000ml flask of packing into, adds 1.5mol hydrochloric acid 1000ml, be heated to 100 ℃ 1 hour, the taking-up acid of desalting of inclining, wash with water to neutrality, send into collodier, obtain the colloid that viscosity is the creamy white of 8000CP with 5% concentration.Embodiment three: bagasse pulp 100g tears the 2000ml flask of packing into, adds 2.5mol hydrochloric acid, be heated to 80 ℃ 1 hour, take out the acid of desalting of inclining, wash with water to neutrality, send into collodier with 10% concentration and obtain the creamy white colloid that viscosity is 32000cp.

Claims (6)

1, a kind of method for making of microcrystal cellulose colloid, this method be with linters 70-150 ℃ of hydrolysis after the gel process, it is characterized in that realizing the gel process by collodier, the disk that collodier is close to mutually by two discs is formed, and a disk of its top is a fixed, and another disk is rotating, disk is provided with opening for feed and discharge port, and the contact surface of two disks is provided with groove.
2, according to the method for making described in the claim 1, the hydrolysis that it is characterized in that linters is with hydrochloric acid or sulfuric acid, and the concentration of acid is 0.2~4mol.
