Abstract

The invention discloses a method for preparing purple perilla seed oil microcapsules by adding corn oligopeptides, and relates to the technical field of preparing purple perilla seed oil microcapsules. The purple perilla seed oil microcapsules comprise core materials and wall materials. The core materials are prepared from purple perilla seed oil, and the wall materials are mixtures of mixed components of one or more than one of Arabic gum, soluble soybean polysaccharide, modified starch, sodium caseinate and soy protein isolatee and corn oligopeptides; the mass ratio of the core materials tothe wall materials is 1:(1-5); and the mass ratio of corn oligopeptides to the wall materials is 1:(4-50). The surface oil content of the perilla seed oil microcapsules is reduced by adding corn oligopeptides to the wall materials to enhance the wall materials and the emulsification of the core materials, the embedding of the purple perilla seed oil by the wall materials is improved, and the oxidization of the purple perilla seed oil is avoided; and the method can be used in the development of nutritionally fortified foods and special dietary foods.

Description

technical field [0001] The invention belongs to the technical field of preparation of perilla seed oil microcapsules, in particular to a method for preparing perilla seed oil microcapsules by adding corn oligopeptides. Background technique [0002] Studies have shown that ω-3 polyunsaturated fatty acids (Polyunsaturated Fatty Acids, PUFAs) have important nutritional value and functional effects, such as preventing and treating cardiovascular diseases. Perilla seed oil has a high degree of unsaturation and contains about 60% α-linolenic acid, so it can be used as an important source of linolenic acid in the development of functional foods. However, due to the poor oxidation stability, water solubility and dispersibility of perilla seed oil, it cannot be widely added to food. At present, how to protect its biological activity to the greatest extent and improve its stability in functional foods has become an urgent problem to be solved in the development of perilla seed oil in...
