Squeezing preparation method for high-purity mountain tea-seed oil and prepared tea-seed oil capsules

Abstract

The invention relates to a squeezing preparation method for high-purity mountain tea-seed oil and prepared tea-seed oil capsules. The preparation method comprises the steps: carrying out seed selecting and stack retting till natural cracking; stripping oil tea seeds, and carrying out kernel-shell separation; crushing tea seed kernels into granules, and carrying out low-temperature freezing and vacuum drying; carrying out primary squeezing, so as to squeeze out 30% to 40% of crude oil and prepare tea seed cakes; carrying out secondary squeezing, so as to squeeze out remaining crude oil; carrying out standing oil clarifying, so as to settle impurities in the crude oil and achieve oil-water separation; and carrying out filtering, selecting crude oil of a middle-upper section of an oil clarifying tank, carrying out centrifugal filtering-standing cycling for 2 to 3 times, and carrying out refining, thereby preparing the high-purity mountain tea-seed oil. According to the method, the retention rate of effective ingredients is high, the oil extraction rate is high, the oil quality is high, and the tea-seed oil and the tea-seed oil capsules, which are suitable for being directly eaten, canbe prepared without decolorization and deodorization; and an entire process is free of any chemical assistant, pure physical methods are adopted, and thus, natural flavors and fruity flavors of mountain tea-seed oil are effectively reserved.

Description

technical field

[0001] The invention relates to the technical field of edible oil production technology, in particular to a method for preparing high-purity camellia seed oil by pressing and the prepared tea seed oil capsule. Background technique

[0002] The physical and chemical properties of tea seed oil are similar to those of olive oil, in which the unsaturated fatty acid content exceeds 80%, especially the linoleic acid content is as high as 20.6%. The main component of camellia oil is glycerol trioleate, which contains sterols, triterpenoids, tocopherols, etc., which is beneficial to the prevention and treatment of cardiovascular and cerebrovascular diseases, obesity and many other affluent diseases, improves human immunity and the function of the gastrointestinal tract, and is beneficial to intellectual development , for almost everyone. The fatty acid composition of camellia oil is similar to that of olive oil. It is called "Oriental olive oil" and is a natural, sa...
