Technical Field
The invention relates to the field of food coloring agents, in particular to a preparation method of a food-grade white pigment with high safety.
Background
Food-grade titanium dioxide (also called white pigment) is mainly used as a coloring agent, a whitening agent and a filling agent of food, has high safety and no toxic or side effect through toxicological evaluation, but titanium dioxide with the grain diameter less than 100nm has the risk of carcinogenesis, and is listed as two types of carcinogenic substances internationally, so that the titanium dioxide is rarely used or not used in food factories; at present, various countries around the world are working on the substitute of titanium dioxide.
Disclosure of Invention
The invention aims to provide a method for preparing food-grade white pigment with high safety.
The innovation point of the invention is that calcium carbonate is used for replacing titanium dioxide, but the calcium carbonate has the following problems: firstly, the calcium carbonate has poor dispersibility in food, secondly, the calcium carbonate can react in gastric acid, so that the calcium supplement of organisms is excessive, and the gastric juice is consumed too much, so that in order to increase the dispersibility and prevent the calcium carbonate from being decomposed in stomach, the calcium carbonate is wrapped by vegetable protein and cellulose, the calcium carbonate particles are wrapped by the vegetable protein, the vegetable protein and the food are easier to mix in the processing according to the similar compatibility principle, and the dispersibility of the calcium carbonate in the food is greatly improved; wrapping calcium carbonate particles with cellulose to ensure that the calcium carbonate does not react with gastric acid in the stomach to achieve the same property of titanium dioxide; meanwhile, because the vegetable protein can be partially digested in the stomach, the calcium carbonate is mixed with the vegetable protein and then mixed with the cellulose, so that the cellulose is wrapped on the outermost layer, namely the vegetable protein is wrapped on the outer surface of the calcium carbonate, and the contact surface between the calcium carbonate and external substances is reduced; the two-layer wrapping of the cellulose is the combination of the cellulose and the outer surface of calcium carbonate and the outer surface of vegetable protein, so that the contact surface between the calcium carbonate and external substances and the contact surface between the vegetable protein and the outer surface are reduced.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a food-grade white pigment with high safety comprises calcium carbonate, plant protein and cellulose, wherein the calcium carbonate is used as a substrate, the plant protein is used as a first wrapping layer, and the cellulose is used as a second wrapping layer.
Furthermore, the weight ratio of the vegetable protein to the cellulose to the calcium carbonate is (5-25): 1-10): 100.
Further, the calcium carbonate is light calcium carbonate, and the particle size of the calcium carbonate is 1-3 mu m. The light calcium carbonate has small grain size and more uniform dispersion.
Further, the cellulose is one or more of methyl cellulose ether, hydroxyethyl ether cellulose, ethyl cellulose, hydroxyethyl cellulose, carboxymethyl cellulose and hydroxypropyl cellulose.
Further, the vegetable protein is one or two mixtures of rice protein or wheat protein.
A preparation method of food-grade white pigment with high safety comprises the following steps:
(1) taking plant protein, cellulose and calcium carbonate, wherein the weight ratio of the plant protein to the cellulose to the calcium carbonate is (5-25): 1-10): 100;
(2) adding water into plant protein and cellulose respectively, boiling until swelling, respectively obtaining a plant protein solution and a cellulose solution, adding calcium carbonate into the plant protein solution, fully and uniformly stirring to obtain a premixed solution, drying the premixed solution, and crushing to obtain a premix;
(3) and adding the premix into the cellulose solution, uniformly stirring again to obtain a mixed solution, drying the mixed solution, and crushing to obtain a finished product.
Further, the drying in the steps (2) and (3) is drying under reduced pressure. The temperature during drying can be reduced, and organic matters in the finished product are prevented from being carbonized.
Further, the pulverization method in the steps (2) and (3) is mechanical pulverization and then airflow pulverization. The particle size is smaller and the dispersibility is better after the jet milling.
The invention has the beneficial effects that:
1. calcium carbonate is used in the present invention instead of titanium dioxide, but calcium carbonate has the following problems: firstly, the calcium carbonate has poor dispersibility in food, and secondly, the calcium carbonate can react in gastric acid, so that the calcium supplement of organisms is excessive, the gastric juice consumption is excessive, and dyspepsia is caused; wrapping calcium carbonate particles with cellulose to ensure that the calcium carbonate does not react with gastric acid in the stomach to achieve the same property of titanium dioxide; meanwhile, because the vegetable protein can be partially digested in the stomach, the calcium carbonate is mixed with the vegetable protein and then mixed with the cellulose, so that the cellulose is wrapped on the outermost layer, namely the vegetable protein is wrapped on the outer surface of the calcium carbonate, and the contact surface between the calcium carbonate and external substances is reduced; the two-layer wrapping of the cellulose is the combination of the cellulose and the outer surface of calcium carbonate and the outer surface of vegetable protein, so that the contact surface between the calcium carbonate and external substances and the contact surface between the vegetable protein and the outer surface are reduced.
