Problems solved by technology

[0003] The traditional peanut oil adopts physical extrusion method, which is to extrude the oil from the peanut kernel. It is divided into two types: hot pressing and cold pressing. The general hot pressing will seriously damage the rapeseed cells, and the nutrients in the oil will be destroyed after high temperature components, reducing the nutritional value and quality of peanut oil, while the cold pressing method has a low oil yield and high residual oil in the cake

Abstract

The invention discloses a processing method for increasing a cold pressing oil yield of aromatic peanut kernels. The processing method comprises the following steps: decocting lavender, chamomile, mint, violet, sweet-scented osmanthus, jasmine and trigonella foenum-graecum with water, filtering to form batching liquid, selecting the high-quality peanut kernels for baking and peeling, cooling to the room temperature, breaking the peanut kernels into particles, adding ground salt after steam heating for a period of time, performing uniform mixing and centrifugation, adding the centrifuged peanut kernel particles into the batching liquid for soaking, adjusting the moisture content of the peanut kernel particles after filtration, performing microwave treatment, performing cold pressing after cooling to form press oil and press cakes, and performing water washing and decoloration on the press oil to form the peanut oil. The processing method for increasing the cold pressing oil yield of the aromatic peanut kernels is high in oil yield, green and nutritional, guarantees pure nature of the peanut oil and meets requirements for green food, and the fragrance is strong.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a processing method for improving the oil yield by cold pressing of Luzhou-flavored peanut kernels. Background technique [0002] Peanut oil is light yellow and transparent, with clear color, fragrant smell and delicious taste. It is a kind of edible oil that is relatively easy to digest. Peanut oil contains more than 80% unsaturated fatty acids (including 41.2% oleic acid and 37.6% linoleic acid). In addition, it also contains 19.9% ​​of saturated fatty acids such as palmitic acid, stearic acid and arachidic acid. The fatty acid composition of peanut oil is relatively good, which is easy for human body to digest and absorb. According to foreign data introduction, use peanut oil, can make cholesterol in human body be decomposed into bile acid and excrete, thereby reduce the content of cholesterol in blood plasma. In addition, peanut oil also contains the materials usef...
