Embodiment Construction

[0017] Take 1000kg of tea seeds, crush them into 100-120 mesh powder, steam and fry them, and press them to get 250kg of crude oil. Because part of the water evaporates after steaming and frying, you can get 700kg of tea seed meal. Dry the tea seed meal for 20 minutes and take it out. Put it into the leaching tank for use; the crude oil obtained by pressing method has less impurities, which is beneficial to improve the quality of oil products;

[0018] The first process: use 200-mesh stainless steel gauze to filter the crude oil to remove solid impurities such as sediment and cake residue, and obtain 240kg of crude oil and put it in the refining kettle;

[0019] The second process: use the hydration method to degumming the crude oil; add 36kg of water to the refining kettle, heat up to make the colloidal impurities expand and condense, remove the colloidal particles to obtain 220kg of crude oil, and place it in the decolorization pot;

[0020] The third process: take a sample ...

Abstract

The invention provides a tea seed processing method which comprises the following steps of: firstly, pulverizing tea seeds into powder with particles of 100-120 meshes; carrying out rough processing to obtain crude oil; primarily filtering and de-gumming; and then detecting the content of benzo (alpha) pyrene of the crude oil; placing active carbon into a decoloring pan according to the weight ratio of the crude oil to the active carbon of 1,000:1 when the content of the benzo (alpha) pyrene is in the range of 10-2ug/kg; heating and stirring to decolor; deodorizing, filtering and polishing to produce product oil; leaching tea seed dregs with ethanol to obtain a tea saponin leaching solution; carrying out triple-effect concentration to obtain a crude tea saponin product; and refining and sub-packaging obtained refined tea saponin to obtain a finished product of the tea saponin. By the tea seed processing method, because tea oil is extracted from the tea seeds, the transparency of the product oil can be enhanced, the nutrient loss of the obtained product oil is less, and the product oil has higher nutritive value; and because the tea saponin is prepared from the tea seed dregs, the utilization efficiency of the raw material is fully improved.

Description

(1) Technical field: [0001] The invention belongs to edible oil processing, and in particular relates to a method for processing camellia oleifera seeds. (two), background technology: [0002] Camellia oleifera is an evergreen small tree belonging to the family Theaceae, and its seeds are called camellia oleifera seeds, which can be used to produce edible camellia oil. Camellia oil is a high-quality edible oil with clear taste and fragrance, rich nutrition and storage resistance. The processing of camellia oil generally uses pressing method or leaching method. Firstly, crude oil is processed, and then refined oil is obtained through degreasing, degumming, dehydration, decolorization, deodorization, deacidification and other processes. Conventional crude oil decolorization uses activated clay for decolorization, but the effect of removing benzo(α)pyrene is not good, which seriously affects the quality of refined oil. The remaining tea seed meal is generally used as fertiliz...
