Description
Technical field
The invention belongs to the treated starch production technical field, be specifically related to a kind of lotus seed starch ultra-high voltage physical modification method.
Background technology
Starch affects outward appearance, mouthfeel, processing characteristics and the nutritive health-care quality of food as the staple in the food.In the food-processing, will experience process procedures such as heat, vigorous stirring or freezing usually in modern times, this will cause the ative starch viscosity to reduce, and destroy its colloidal property.Along with science and technology development, the continuing to bring out of product innovation, more and more harsher to the requirement of starch property, the character of native starch can not satisfy the demand of industrial development.Therefore, starch structure and physico-chemical property are carried out modification and handle the big focus that the requirement that makes it to meet industrial applications has become current starch research field.
Lotus seeds are precious good merchantable brands of important special product economic resources of China and medicine-food two-purpose, and at home and abroad city's field depth receives human consumer's favor.Lotus seeds are high starchiness agricultural-food; Starch accounts for the lotus seeds solids content more than 50%, and wherein amylose content belongs to the high specificity starch of amylose content up to 42%; This special construction has caused lotus seed starch to be easy to return life, has influenced the quality of starchy food product.The relevant study on the modification of carrying out the lotus seed starch quality characteristic has great importance, and helps to improve structure, physicochemical property and the eating quality of lotus seed starch, the range of application of expansion lotus seed starch.
According to the changing conditions after starch conversion technological method and the modification, starch conversion can be divided into chemical modification, physically modified, enzyme-modified and composite modified four types.Consider food safety, chemical modification technique more and more is restricted, and physically modified and enzyme-modified then can overcome the deficiency of chemical modification.Physical modification method mainly contains preparatory gelatinization, extrusion process, thermal treatment, radiotreatment, uhp treatment, ultrasonication, microwave treatment and radiation modification etc.
Superhighpressure technology is a modern food processing new and high technology.This patent adopts superhighpressure technology that lotus seed starch is carried out modification; The food superhighpressure technology is meant being sealed in (Chang Yishui or wet goods fluid medium are as the vehicle of transmitting pressure) in the ultrahigh pressure vessel after the food raw material packing; Make food high pressure (100～1000MPa) with certain temperature under handle appropriate time; Cause biopolymer material inactivation, gelatinization, sex change such as enzyme in the food, starch, protein; And kill the mikrobes such as bacterium in the food, thus reach sterilization, material modification and produce new weave construction, improve the purpose of Food Quality.
Summary of the invention
The object of the present invention is to provide a kind of lotus seed starch ultra-high voltage method of modifying, lotus seed starch has improved starch structure, physicochemical property and eating quality after uhp treatment, expanded the range of application of lotus seed starch.Uhp treatment is a kind of novel method of physically modified starch, for a new way has been opened up in the production of treated starch.This method of modifying technology simply, more traditional starch conversion method weak point consuming time, little, simple to operate, the safety non-pollution of energy consumption.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
A kind of lotus seed starch ultra-high voltage method of modifying is to be raw material with the lotus seed starch, in lotus seed starch, adds water and is mixed with the lotus seed starch breast, carries out uhp treatment after the vacuum packaging, obtains finished product behind dry, the crushing screening.
The concrete steps of said method are following:
(1) preparation of raw material: take by weighing lotus seed starch, add entry, mixing, being mixed with mass and size concentration is the lotus seed starch breast of 15-20%;
(2) vacuum packaging: the lotus seed starch breast for preparing is carried out vacuum packaging, and the lotus seed starch breast that is about to prepare is packed in the polypropylene film bag, adopts Vacuum Packaging Machine to carry out seal package;
(3) uhp treatment: the lotus seed starch breast that vacuum packet is installed places hyperbaric chamber to carry out uhp treatment, and the condition of uhp treatment is pressure 450-500MPa, and temperature 25-30 ℃, dwell time 20-30 minute;
(4) drying: with the lotus seed starch after uhp treatment breast suction filtration be placed on dry in 45 ℃ of loft drier to moisture content be 5-10%;
(5) crushing screening: the lotus seed starch after will drying grinds the back and crosses 80 mesh sieves.
Remarkable advantage of the present invention is:
(1) superhighpressure technology and traditional starch conversion technology compares, and advantage is: uhp treatment is a physical process, only acts on non covalent bond (hydrogen bond, ionic linkage and hydrophobic bond etc.), and covalent linkage is not destroyed basically.Uhp treatment can not make physical property such as food color change, and can not produce peculiar smell, and pressurization back food still keeps original fresh local flavor and nutritive ingredient.After the uhp treatment, the gelatinization state and the heat treated of starch are different, thereby obtain novel rerum natura food.
(2) grain pattern and the molecular characterization of the lotus seed starch after the ultra-high voltage modification change, and have improved structure, physicochemical property and the eating quality of lotus seed starch, have expanded the range of application of lotus seed starch, for a new way has been opened up in the production of treated starch.
(3) production technique of the present invention is scientific and reasonable, is easy to control, and is workable, and power consumption is few, environment friendly and pollution-free, is convenient to realize cleaner production continuous, robotization.
