Embodiment 1

[0032] A processing method of "one-step method" refined tea seed oil is characterized in that comprising the following steps:

[0033] (1) Pump 1.9t machine-pressed fresh tea seed crude oil into the alkali refining tank, and add metered Na at a speed of 70 rpm 2 co 3 6.70kg and 0.2% activated carbon;

[0034] (2) Low temperature treatment: heating at 35°C for 30 minutes;

[0035] (3) Medium and low temperature treatment: heating at 80°C for 120 minutes;

[0036] (4) Pump into the dehydration tank, vacuum dehydrate until the water content is 0.2%, the dehydration conditions are: 90℃, 10kpa;

[0037] (5) Stop heating, stand still, separate and precipitate, and press filter to obtain refined product oil.

[0038] In this embodiment, the acid value of the crude oil to be processed is measured to be 3.75, and the calculated Na 2 co 3 The dosage is 6.70kg.

Abstract

The invention relates to a processing method for refining tea seed oil by a one-step process. The method comprises the following steps: by using a food additive mixture composed of a food additive and a food processing aid instead of a sodium hydroxide (NaOH) water solution and argil, processing for 2-2.5 hours at low temperature and medium low temperature to complete deacidification, debitterizing, decolorization and peroxide value (POV) reduction by one step, and carrying out vacuum dehydration, precipitation separation and filtration to obtain the refined product oil. The method does not need to add water, does not use NaOH, argil or enzyme preparation, does not need vacuum deodorization treatment, has the advantages of less processing equipment, simple technique, short processing cycle and no discharge of argil and sewage, can not generate trans fatty acid, and well maintains the nutritional ingredients and physiologically active substances in the crude oil; the oil product has obviously better color, aroma, flavor and mouthfeel than the refined oil processed by the salad oil technique; and the 1.9t trial production on a production line proves that the quality of the refined oil reaches or exceeds Grade 1 in National Standard for Edible Oil-Tea Seed Oil.

Description

technical field [0001] The invention mainly relates to the field of oil processing, in particular to a "one-step" processing method for refining tea seed oil. Background technique [0002] Tea seed oil is a general term for extracting oil from the seeds of Camellia family plants such as tea, camellia oleifera, camellia and camellia. It has a history of more than 2,300 years to extract oil from the seeds of Camellia plants for consumption in my country. Therefore, tea seed oil is the national oil of our country. Its nutritional value and health care function are better than olive oil, a healthy nutritional oil recommended by the World Health Organization, but tea Crude seed oil contains a bitter and pungent compound, tea saponin or tea saponin, which is a pentacyclic triterpenoid compound. It is difficult to directly import it because of its bitter taste, and because the folks have misrepresented that tea seed oil is poisonous for a long time, which seriously hinders the cons...
