Abstract

The invention provides wild tea seed oil and a production process thereof. The process is characterized by comprising the following sequential steps: (A) husking with a husking machine so as to obtain wild tea seed kernels; (B) drying the wild tea seed kernels in the air, and controlling the moisture content to be 4%; (C) pressing the sun-dried wild tea seed kernels with a hydraulic press so as to produce raw oil; (D) precipitating the raw oil for 36-48 hours, and then, filtrating, so as to obtain finished oil. The wild tea seed oil provided by the invention is strong and fragrant in smell and unique in flavor, can be extensively applied to the cooking of various kinds of foods and dishes, and has relatively high nutritive values and health protecting and health preserving functions, and high-oxidation-resistance active ingredients are ensured, so that the wild tea seed oil is particularly suitable for being popularized to the technical field of small-lot special oil production.

Description

Wild tea oil and production technique thereof

Technical field

The present invention relates to a kind of method of producing wild tea oil, art: two, biological and new medical technology, (seven) modern agricultural technology, 4, agricultural-food intensive processing and modern accumulating: agriculture and forestry product and extraordinary enhance productivity are processed.

Background technology

Producing of China's tea oil generally adopts milling process and lixiviation process.The sixties 20th century of oil extraction by pressing adopts hydropress later, generally adopts 95 types and 200 type expellers after the seventies, and rural oil pressing factory (mill) the hydropress oil expression in current vast producing region still accounts for very large proportion.After 20 century 70s, oil tea also adopts leaching-out technique, but large absolutely number carries oil for oil cake, but the tea oil produced lacks fragrant, color is dark.

Chinese patent discloses the making method of CN 1827754 physical low-temperature cold-squeezing process for tea-seed oil and publication number 101899360B aromatous camellia seed oil, but, these 2 kinds of working method techniques are loaded down with trivial details, employ high temperature and chemical reagent, lose very large to the nutrition and health care composition of wild tea seed.Prepare a kind of edible fat production working method with wild tea seed for raw material also not study.

Summary of the invention

The object of the present invention is to provide a kind of wild tea seed edible fat production method of easy, nutritive value and health care, rational technology.

Technical scheme of the present invention is achieved in that and comprises the steps:

A, to peel off with decorticator, obtain wild tea benevolence;

B, airing is carried out to wild tea benevolence, control water ratio 3%-5%;

C, the wild tea benevolence hydropress dried is added extrusion crude oil;

Wild tea benevolence is made cake and puts into hydropress, often squeeze and throw cake 20-25 block, every block is about 4-6kg, equably pressurized hydraulic low pressure, when making pressure be pressed onto 110-120MPa, low pressure is transferred to high pressure, and uniform pressurization is to during 280-300MPa, during squeezing, can not be too fast, in order to avoid cake slag oozes out.

Filter after D, crude oil precipitation 36 ~ 48h, obtain processed oil.

After crude oil precipitation 36 ~ 48h, oil is evenly crossed through flame filter press and filters impurity, obtain processed oil.

Advantage of the present invention is:

Production technique of the present invention get oil product colour shallow, have the special odor of wild tea seed and remain nutritive ingredient; Oven dry in traditional technology, steaming are fried and decoloration process needs to add gac or atlapulgite, oven dry is got oil and is made the increase of benzopyrene content need to add charcoal absorption, steam fry get oil color more deeply need to add activated decoloration, although can remove unfavorable factor, complicated operation, interpolation chemical substance can remove the special odor of nutritive ingredient and wild tea seed.

The invention provides the wild tea seed oil producing method of a kind of easy, nutritive value and health care, rational technology, can produce for short run special oil and technical support is provided, be suitable for promoting in edible fat production technical field.

Embodiment

Wild tea seed edible fat production technique:

A, to peel off with decorticator, obtain wild tea seed kernel;

B, airing is carried out to wild tea seed kernel, control water ratio 4%;

C, the wild tea seed kernel hydropress dried is added extrusion crude oil;

Wild tea seed kernel is made cake and puts into hydropress, often squeeze and throw cake 23 pieces, every block is about 5kg, equably pressurized hydraulic low pressure, when making pressure to 115MPa, low pressure is transferred to high pressure, uniform pressurization to during 285MPa, during squeezing, can not too soon, in order to avoid cake slag oozes out.

Filter after D, crude oil precipitation 36h, obtain processed oil.

After crude oil is precipitated 36h, oil is evenly crossed through flame filter press and filters impurity, obtain processed oil

The present invention can be used for special oil and produces, and is applicable to nutritive value and health care's edible fat production, accomplishes pollution-free, less energy-consumption.

Claims

1. a working method for wild tea oil, is characterized in that comprising the steps:

A, to peel off with decorticator, obtain wild tea benevolence;

B, airing is carried out to wild tea benevolence, control water ratio 3%-5%;

C, the wild tea benevolence hydropress dried is added extrusion crude oil;

Wild tea benevolence is made cake and puts into hydropress, often squeeze and throw cake 20-25 block, every block is about 4-6kg, equably pressurized hydraulic low pressure, when making pressure to 110-120MPa, low pressure is transferred to high pressure, and uniform pressurization is to during 280-300MPa, during squeezing, can not be too fast, in order to avoid cake slag oozes out.

Filter after D, crude oil precipitation 36 ~ 48h, obtain processed oil.
