preparation example Construction

[0026] A method for preparing blended oil with a balanced ratio of fatty acids, the method comprising the following steps: (1) After cleaning soybeans, rapeseed, perilla, hempseed and evening primrose seeds, they are pulverized with a cyclone mill, and after pulverization, they are proportionally The mixed oil is obtained by mixing, and the percentage of each component by weight of the mixed oil is as follows: 1.1% soybean addition, 32.5% rapeseed addition, 2.3% perilla addition, 40.5% hemp seed addition, monthly see The amount of grass seeds added is 23.6%; (2) The mixed oil obtained in step (1) is added with water to form a mixed solution, the ratio of the mixed solution to liquid is 1:5, and the mixed solution is subjected to ultrasonic pretreatment. The ultrasonic time is 20-60min, the ultrasonic temperature is 30-70°C, and the ultrasonic intensity is 100-500W; (3) Adjust the pH of the mixture after ultrasonic pretreatment in step (2) to 5.5, and then add compound The enzy...

Abstract

The invention relates to a preparation method for a blend oil with a balanced fatty acid ratio, and belongs to the plant oil extraction processing technology. The method comprises: (1) carrying out cleaning and crushing on soybean, rapeseed, perilla frutescens, hemp fruit and evening primrose seeds, and mixing according to a certain ratio to obtain a mixing oil material; (2) adding water to the mixing oil material to prepare a mixing solution, and carrying out an ultrasonic pre-treatment on the mixing solution; (3) adding a compound enzyme to the ultrasonic pre-treated mixing solution to carry out enzyme digestion wall breaking; and (4) adding protease to the digested mixing solution to carry out enzyme digestion, carrying out centrifugal separation to obtain free oil, a hydrolysis solution, an emulsion and residue, carrying out freezing-thawing emulsion breaking on the emulsion to obtain the free oil, and mixing the two free oils to obtain the blend oil with the balanced fatty acid ratio. According to the present invention, the five oil materials are mixed according to a certain ratio, and the ultrasound combined enzyme digestion is adopted to prepare the blend oil with the balanced fatty acid ratio, wherein the fatty acid ratio is close to the ratio of SFA to MUFA to PUFA of 0.27:1:1 and the ratio of Omega6 to Omega3 of 1-5:1, and nutritional needs of different groups can be met.

Description

technical field [0001] The invention belongs to the technical field of vegetable oil extraction and processing, and mainly relates to a method for preparing blended oil with balanced fatty acid ratio. Background technique [0002] At present, the health awareness of the whole people has been significantly improved, and the intake of fat is an essential part of daily life. In recent years, due to the increasing number of diseases such as hyperlipidemia, arteriosclerosis, and coronary heart disease, it has attracted people's attention. The cause of these diseases is closely related to the unbalanced fatty acid consumption of people. Excessive intake of saturated fatty acids with more than twelve carbons (excluding stearic acid) will not only lead to elevated cholesterol in the human body, but also cause serious damage to human health. Arteriosclerosis and Coronary heart disease; intake of polyunsaturated fatty acids rich in n-6 series (linoleic acid, gamma-linolenic acid, ar...
