Embodiment Construction

[0018] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0019] In the embodiment of the present invention, a kind of subcritical extraction process of tea oil with peach pit and tonifying brain, the specific steps are as follows:

[0020] (1) Raw material pretreatment: choose camellia seed, walnut, black sesame, sunflower seed, pumpkin, corn germ, peanut, and millet as raw materials, and dry in an oven at 40°C for 47 hours to obtain a dried peach mixture with a moisture content of 5%. , and then put the dried mixture into a pulverizer to pulverize and pass through a 55-mesh sieve to obtain the mixture powder for subsequent use;

[0021] (2) Loading: Weigh 500.3g of the above mixture powder, put it into a 200-mesh mesh silk and put it into the subcritical extraction kettle, and use a vacuum pump to make the vacuum degree in the subcritical extraction kettle and the separation kettle be -0.05MPa;

Abstract

The invention discloses walnut brain nourishing tea oil and a subcritical extraction technology thereof. The technology specifically comprises the following steps: selecting camellia seed, walnut, black sesame, sunflower seed, pumpkin, corn germ, peanut and millet; grinding, sieving and mixing for later use; with subcritical fluid as an extraction solvent, repeatedly extracting walnut brain nourishing tea powder by using a subcritical fluid extraction device; after the extraction, separating the extraction solvent from target product in a way of compressor desolvation and vacuum pump-compressor linked desolvation to obtain crude oil; and performing refined filtration on the crude oil to obtain high-quality walnut brain nourishing tea oil. The method has the characteristics of easiness in operation, low energy consumption, little pollution, short extraction time and high oil extraction rate and facilitates industrial production. The subcritical fluid extraction technology is finished in a low-temperature condition, and the physicochemical properties and nutritional ingredients of the target product can be protected from damage; and moreover, the refining processes are reduced, the industrial cost is lowered, and the technology is of great significance to the industrial production of new-resource functional grease.

Description

technical field [0001] The invention relates to the field of functional vegetable oil extraction, in particular to a subcritical extraction process of high-quality peach-pit brain-invigorating tea oil. Background technique [0002] At present, the methods used to extract vegetable oils at home and abroad mainly include pressing method, leaching method and supercritical extraction method. Due to the high temperature of the pressing method, the oil is easy to oxidize and deteriorate; the leaching method has solvent residues and the post-treatment process is complicated; the production scale of supercritical fluid is small, which limits industrial production. Sub-critical fluid extraction (Sub-critical fluid extraction technology) is to use sub-critical fluid as the extraction agent, in a closed, anaerobic, low-pressure pressure vessel, according to the principle of similar solubility of organic matter, through the extraction material and extraction agent in the soaking process...
