Soybean oil powder grease and preparation method thereof

Abstract

The invention relates to soybean oil powder grease and a preparation method thereof. Concretely, soybean first-grade oil is used as a raw material to be used as core materials, a microencapsulation embedding technology is adopted, and a novel series soybean oil powder grease product with excellent processing characteristics and rich and mass nutrients is developed through the selection of an embedding agent, a filling agent and an emulsifying agent and the optimization of process conditions. The improvement is carried out on the trial test study, an industrialized production and test recipe is obtained. During the proportioning, the soybean oil powder grease comprises the following ingredients in percentage by weight: 9.25 percent to 27.25 percent of core material, 1.35 percent to 2.7 percent of embedding agent, 13.925 percent to 33.8375 percent of filling agent, 0.5625 percent to 1.125 percent of emulsifying agent and 55 percent of water. Compared with ordinary liquid-stage grease products, the product has various advantages that the quality guarantee period of the product is prolonged, the product functionality is improved, the product water solubility is improved, and the product application range is enlarged.

Description

technical field [0001] The invention relates to a soybean oil powder grease and a preparation method thereof, belonging to the field of food processing. Background technique [0002] Most foods belong to a multi-component colloidal mixture with a complex structure, which is composed of various nutrients and are also highly susceptible to external adverse environmental factors (light, temperature, pH, oxygen, water, etc.) Deterioration and loss occur due to the influence, especially for liquid fats such as soybean oil. Soybean oil contains 80% unsaturated fatty acids, which is extremely nutritious, but has the problem of easy oxidation. Microencapsulation technology has the following functions: it can protect the embedded core material and avoid adverse reactions with other components; it can isolate it from external adverse environmental factors, and while maintaining the original color, aroma and taste of the core material, it reduces the Deterioration and loss or prolong...

AI Technical Summary

Problems solved by technology

[0005] At present, most of the raw materials of microencapsulated powder oil products produced in China are solid fats. For example, most of the raw materials for making milk tea, formula milk powder, and ice cream powder are coconut oil, palm oil, etc., and the technical difficulty is relatively low. There are few researches on the microencapsulation products of soybean primary oil. Since the content of short-chain unsaturated fatty acids in soybean primary oil is high, it is liquid at room temperature, so the embedding effect and embedding strength of soybean oil are relatively high. requirements

In this regard, Fu Xiaoyi of the National Soybean Engineering Technology Research Center and others have studied the conditions of microencapsulated powdered soybean oil wall materials and emulsifiers ("Research on microencapsulated powdered soybean oil wall materials and emulsifiers", Soybean Bulletin, No. 2, 2005), but so far, the industrialization and market application of soybean powder oil products are still blank, and the research is still in the laboratory stage
