Problems solved by technology

However, plasticizers such as bis(2-ethylhexyl) phthalate, urea, formamide and acetamide have certain toxicity, and are harmful to human body after excessive intake, and can cause gastrointestinal dysfunction, cancer, etc.
However, starch-based materials obtained by using glycerin and polyethylene glycol as plasticizers are easy to absorb water and are sensitive to environmental humidity, resulting in large changes in mechanical properties and lack of stability during use.

Abstract

The invention relates to the technical field of edible oil, in particular to a method for preparing a camellia oleosa seed oil plasticizer and the application thereof. The method is characterized by comprising the steps of 1, oxidizing modification; 2, distillation dehydration; 3, centrifugal decontamination. The plasticizer prepared with the method can replace bis(2-ethylhexyl) phthalate, high-boiling-point polyol, amide micromolecule and other common plasticizer, and is widely applied to plastification of a starch-base material. Compared with the prior art, the plasticizer has the advantages of being safe, free of toxin and environment-friendly; a starch film obtained through plastification with the plasticizer has high transparency, mechanical property, retrogradation resistance and degradability, can be widely applied to fields including food, and is an ideal edible food packaging material.

Description

【Technical field】 [0001] The invention relates to the technical field of food oil processing, in particular to a preparation method and application of a camellia oleifera seed oil plasticizer. 【Background technique】 [0002] With the increasing attention of human beings to environmental protection and energy, the development of renewable degradable polymer materials has become a research hotspot at home and abroad. Starch has been an abundant, renewable and inexpensive natural macromolecular material for two hundred years. Compared with most synthetic polyolefins, starch-based materials can be completely degraded after use and will not pollute the environment. However, starch molecules contain a large number of hydroxyl groups, and the inter-molecular and intra-molecular oxygen bonds are very strong. When it is directly heated, the starch will start to decompose before it reaches the theoretical melting temperature, and the processing performance is poor. In order to make ...
