Technical field

The present invention relates to technical field of agricultural product process, in particular to a kind of tea-seed oil processing method.

Background technique

Tea-seed oil is using tea seed by oil ingredient in the tea seed extracted of method of squeezing or chemical extraction, with oil The fruit tea seed tied on tea tree is raw material；In tea seed be free of erucic acid, cholesterol, aflatoxins and other additives, according to the study Show: tea-seed oil unsaturated fatty acid content is up to 90% or more, and oleic acid reaches 80-83%, and linoleic acid reaches 7-13%, and is rich in Protein and the nutritional ingredients such as vitamin A, B, D, E, the especially linolenic acid contained by it are needed by human and cannot synthesize Ingredient；Tea-seed oil has remarkable efficacy to cardiovascula arteriosclerosis, lowering blood pressure and blood fat etc., and occupy the special efficacy of cancer-resisting, Its high nutritive value and health care valence are increasingly favored by people.

Tradition squeezes tea-seed oil technique are as follows: picking fruit is returned, and air dry fruit opens shell, dries ribes, smashes milling, Steam by water bath It is ripe, then squeezed；Or tea seed is cleaned up and is dried, then remove tea seed episperm tea seed remove one layer of outside it is hard Shell, it is raw to squeeze, filter.The tea-seed oil purity that tradition squeezes the preparation of tea-seed oil technique is low, have bitter taste, while the utilization of tea seed meat benevolence more Rate is low, causes the waste of raw material.

Summary of the invention

In order to overcome the disadvantages mentioned above and deficiency of the prior art, the purpose of the present invention is to provide a kind of tea-seed oil processing sides Method, the tea-seed oil purity is high being prepared, without bitter taste, while the utilization rate of tea seed meat benevolence is high, reduces waste.

The purpose of the present invention is achieved through the following technical solutions:

A kind of tea-seed oil processing method, comprising the following steps:

(1) to tea seed fruit decladding, full kernel is obtained；

(2) it is 7 ~ 9% that Quan Guoren, which is fried to moisture at 118 ~ 122 DEG C,；

(3) the good full kernel of frying is cooled to 58 ~ 62 DEG C and is squeezed, controlled at 98 ~ 102 DEG C in expressing process；

(4) the obtained tea-seed oil of squeezing filtered, precipitate after be sealed.

Preferably, described in step (1) to tea seed fruit decladding, specifically: the fresh full fruit of tea seed fruit is dried in the shade until tea seed Shell falls off, and obtained tea seed is dried under the sun, then removes the black inner casing outside tea seed meat benevolence by hulling machine.

Preferably, step (2) is described in 118 ~ 122 DEG C of fryings, specifically: 118 ~ 122 DEG C frying 28 ~ 35 minutes.

Preferably, step (3) squeezing, specifically: it is squeezed using pressafiner.

Preferably, step (4) filtering, specifically:

Oil is separated with disintegrating slag with suction net, then is filtered by oils filter-press.

Preferably, step (4) precipitating, specifically: precipitating 15 ~ 18 days.

Preferably, step (4) is described is sealed, specifically: tea-seed oil is packed into room temperature storage in closed container.

Compared with prior art, the present invention has the following advantages and beneficial effects: preparation method of the invention, by frying The full kernel of tea seed cools to 58 ~ 62 DEG C and is squeezed, and controlled at 98 ~ 102 DEG C in expressing process, both ensure that in tea seed has Imitating active constituent can be unlikely to destroy the molecular structure of tea seed kernel sufficiently with grease separate out, using method of the invention The tea-seed oil of preparation has a fruit flavor, and mellowness, purity is higher, without bitter taste, and nutritive value is higher, while the utilization of tea seed meat benevolence Rate is high, reduces waste.

Specific embodiment

Below with reference to embodiment, the present invention is described in further detail, embodiments of the present invention are not limited thereto.
