Abstract

The invention discloses a method for preparing fructus cannabis protein with high oil holding capacity and emulsifying activity, and belongs to the technical field of foods. The method comprises the following steps of firstly, pretreating fructus cannabis by ultrasonic combined acid leaching; then crushing the pretreated fructus cannabis, and carrying out extracting and separating by a water substitution method so as to obtain clear oil, emulsion, water phase and residue phase; and finally, performing acid precipitation on the obtained water phase so as to obtain the fructus cannabis protein. The prepared fructus cannabis protein has the advantages that the oil holding capacity, emulsifying activity and in-vitro digestibility are better; and by utilizing the properties, the fructus cannabis protein can be well applied to the fields of foods, such as infant complementary foods, body building foods, special medical foods and cooking oil, the comprehensive utilization rate of fructus cannabis resources is improved, and the application field of the fructus cannabis protein is widened.

Description

technical field [0001] The invention relates to a method for preparing hemp seed protein with high oil retention and emulsifying activity, belonging to the technical field of food. Background technique [0002] About 90% of the world's edible vegetable oils come from palm, soybean, rapeseed and sunflower, compared with hemp oil which occupies only a small part of the edible oil market. However, hemp has a very high utilization value. Hemp oil, hemp protein, and cannabidiol have attracted more and more attention from researchers because of their excellent physiological functions and nutritional value, which has promoted the growth of the global industrial hemp market. Currently, the utilization efficiency of hemp resources is very low, especially the utilization of hemp seeds. In most production areas of my country, hemp oil is extracted by pressing, and the remaining hemp meal is discarded or used as feed and fertilizer, which leads to a serious waste of hemp seed resources...
