Abstract

The invention discloses a degumming method for camellia oil, which comprises the following steps: heating primary camellia oil to between 40 and 70 DEG C, and adjusting the pH value of the primary camellia oil to between 3.0 and 6.5; adding phosphatidase and stirring the mixture under heat insulation condition; and finally filtering or centrifugally separating the mixture. The camellia oil degummed by the method has low content of phospholipid, and the camellia oil degumming efficiency is high; and the method has simple process, mild reaction conditions and easy control.

Description

A kind of Degumming method of Camellia oil
Technical field
The invention belongs to food processing field, be specifically related to a kind of Degumming method of Camellia oil.
Background technology
Camellia oil obtains from Theaceae tea oil tree seed, be rich in natural VA, VD, VE, VK, carotene, and various active compositions such as tea-polyphenol, squalene, have effects such as prevention cardiovascula arteriosclerosis, hypotensive, reducing blood-fat, anti-hepatitis, cancer-resisting.In recent years, along with the improvement of diet formula, the enhancing of people's health care consciousness, the favor that tea oil obtains the human consumer with its abundant nutrition and function, development is rapidly.
Tea seed is through the coarse tea oil that squeezing or leaching method extract, and filters, comes unstuck, refining steps such as depickling, deodorization, decolouring, winterization are edible.Coming unstuck is one important procedure in the Camellia oil refining process, and Camellia oil comes unstuck and mainly adopts hydration degum and acid to come unstuck two kinds at present, and additive method is less.Not about the publication of Camellia oil degumming technology, following several method is arranged at present for other plant degumming of oil technology.Publication number is the patent of invention " a kind of method of fat degumming " of CN1935964A, proposing the fat degumming method is, crude oil is heated to 60 ℃~70 ℃, add oil and weigh 0.05%~0.2% phosphoric acid or citric acid, through fast-mixing reactor, oil is fully contacted with acid, afterwards grease is cooled to 40 ℃~45 ℃ by condenser, enter acid-respons jar reaction 60~90min, the soft water that adds phosphorus acid content 1:1 then, add-on is that oil is heavy by 1%~2%, add simultaneously oil heavy 1%~3%, concentration is 2~3% flocculation agents and neutralization reaction alkali lye, enter hydration reaction jar reaction 20~30min, enter separating centrifuge then and separate, the degummed oil after the separation gets final product through the vacuum drier dehydration.Publication number is the patent of invention " processing method of a vegetable oil waterless degelatinizing " of CN1445348A, it is characterized in that crude oil is adjusted temperature to 25 ℃~60 ℃, under the pump pressure of 0.2~0.6Mpa, squeeze in the degumming machine and come unstuck through the stepless speed regulation pump, make colloid and separating of oil, thereby draw finished product vegetable oil.Publication number is the patent of invention " a kind of method that keeps the squeezing peanut oil anhydrous dephosphorization fat of fragrance " of CN1814719A, the peanut oil Degumming method that proposes is, filter under 14 ℃~22 ℃ condition with pressed oil, phosphatide in the disjoining pressure oil expression, under cold condition, colloid disperse phase particle in the squeezing peanut oil attracts each other and produces cohesion, is floss and separates out, and filters and can remove phosphatide.Publication number is the patent of invention " degumming process for edible oil " of CN1079985A, the degumming technology that proposes a kind of edible oil is, adopt adsorption medium that peptized impurities is adsorbed, the adsorption medium that will adsorb peptized impurities by press filtration removes then, reaches the purpose of coming unstuck.Publication number is the patent of invention " a kind of method of enzymatic degumming of oil " of CN1293706A, proposes the improving one's methods of content that a kind of enzymatic reduces phosphorus containing components in the edible oil, and this method comprises uses Phospholipid hydrolase and less water.Publication number is the patent of invention " enzymatic degumming method of vegetables oil " of CN1112156A, the Degumming method that proposes a vegetable oil is, vegetables oil pH value is transferred to 6 from 3, and with the aqueous solution that contains a kind of enzyme among phospholipase A1, A2 or the B, in temperature is under 20~90 ℃, and this enzyme works to vegetables oil in the reactor that comes unstuck that stir on the limit.
Edible oil degumming mainly adopts hydration degum and acid to come unstuck in the prior art, needs through washing, causes the processed oil loss bigger, and temperature is higher, and is unfavorable to the quality of oil, and do not have corresponding patent report about the degumming technology of Camellia oil.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes prior art, and purpose is to provide a kind of and reduces the processed oil loss, guarantees that quality, the technology of tea oil is simple, reaction conditions is gentle and the Degumming method of the Camellia oil of easy control.
The present invention is achieved through the following technical solutions above-mentioned purpose:
A kind of Degumming method of Camellia oil is that coarse tea oil is heated to 40~70 ℃, and the pH value is adjusted to 3.0~6.5; Add Phospholipid hydrolase; Insulated and stirred; Filter or centrifugation.
The described preferred 20~100mg/kg coarse tea oil of amount that in the coarse tea oil that regulates pH and temperature, adds Phospholipid hydrolase Lecitase Ultra.
Described insulation mixing preferably under 40~70 ℃, stirs 1~5h at a slow speed.
Described with coarse tea oil after filtration or centrifugation, effect is tea oil and oil foot are separated, and obtains the tea oil that comes unstuck.
The present invention compared with prior art, following advantage and beneficial effect are arranged: (1) phospholipids content that comes unstuck in the Camellia oil is low, the tea oil efficient height that comes unstuck, comparing fat degumming method commonly used at present has hydration degum and acid to come unstuck two kinds, after crude oil for same phospholipids content adopted hydration degum, acid is come unstuck and enzyme of the present invention comes unstuck, phospholipids content dropped to 32.5mg/kg, 18.7mg/kg, 9.6mg/kg respectively in its tea oil; (2) temperature of coming unstuck is low, and few to the destruction of bioactive ingredients in the Camellia oil, the quality of the Camellia oil that comes unstuck is good, and acid value is low, and is favourable to follow-up refining procedure depickling; (3) do not have soap stock to produce, need not washing, reduce the loss of tea oil in the process of coming unstuck, reduce the generation of waste water, free from environmental pollution; (4) technology is simple, reaction conditions gentleness, control easily.
