Camellia oil and processing process thereof

Abstract

The invention discloses camellia oil and a processing process thereof. The processing process comprises the following steps: a, firstly, performing camellia seed collection and storage treatment on araw material; b, after the step a is completed, pretreating the raw material; c, after the step b is completed, treating with a cold pressing machine; d, after the step c is completed, performing oil-residue separation through plate frame filtration; e, after the step d is completed, performing secondary extraction on oil cakes; f, after the step e is completed, processing pressed crude camellia oil through alkali refining. On the basis of cold pressing, food additives are added, so that the stability, the anti-oxidation effect and the thermal stability of oil can be improved; secondly, a leaching method is implemented, since oil cells are not completely damaged in a pretreatment process, and albuminous degeneration is not very thoroughly achieved, barrel pressure is not very large, and the oil residue rate of pressed cakes is relatively high, an effect of extracting oil from oil cakes twice can be achieved together with the leaching method, the oil residue rate is reduced, the oil extraction effect is improved, and convenience can be brought to popularization and application.

Description

technical field [0001] The invention relates to the technical field of camellia oil processing technology, in particular to camellia oil and its processing technology. Background technique [0002] Camellia oil (also known as wild camellia oil, camellia seed oil, camellia oleifera seed oil) is obtained from the seeds of the Camellia oleifera tree. The production process of camellia oil can be divided into: shelling, drying, crushing, steaming, oil pressing, filtering, the whole process is physical method, so it is a real pure natural green edible oil, tea oil does not contain erucic acid, Cholesterol, aflatoxin and other additives. After testing: the unsaturated fatty acid in camellia oil is as high as 90%, oleic acid reaches 80-83%, linoleic acid reaches 7-13%, and it is rich in protein and vitamins A, B, D, E, etc., especially its The rich linolenic acid is necessary for the human body but cannot be synthesized. Camellia oil is rich in nutrition and contains fatty acids ...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing camellia oil generally adopts cold pressing and leaching methods in the processing process, but in actual use, the separate cold pressing treatment, on the basis of ensuring the oiliness of the camellia oil, because the oil quality contacts with air, produces The oxidation effect will gradually consume the oil. Secondly, the nominal cold pressing will have local high temperature when the cold pressing machine is running, which will affect the oil quality and cause the color to become darker. Then the oil cake after cold pressing , because when the oil is produced by pressing, the pretreatment process cannot completely destroy the oil plant cells, and the protein denaturation cannot be completely complete; the temperature of the pressing chamber cannot be very high, and the pressure of the pressing chamber cannot be very high
