Problems solved by technology

[0003] However, because the bulk oil degumming process is adopted, the degumming is not carried out according to the characteristics of the oil product, so that the nutrient content of the oil product is lost, and the quality of the oil product is not high; Vacuum dehydration causes a large loss of flavor components in the oil

Embodiment 1

[0030] Put the crude oil of camellia oleifera seed into the degumming tank, add 0.15% of 25Be ° citric acid solution accounting for the total amount of crude oil, first stir rapidly for 5 minutes, then stir at a slow speed of 10 rpm for 118 minutes, then add 10% NaCl solution slowly Stir at high speed for 30 minutes to separate the oil feet in the oil;

[0031] The Camellia oleifera seed oil after separation of the oily residue is washed with water for the first time: add 80°C hot water according to 5% of the crude oil amount and 25Be° citric acid solution accounting for 0.005% of the crude oil amount for rapid mixing for 4 minutes, then slowly Stir at high speed for 10 minutes, oil and water are separated;

[0032] After oil-water separation, the Camellia oleifera seed oil is washed twice: add 4% NaCl solution at 60°C according to 8% of the crude oil, mix quickly for 4 minutes, then stir slowly for 10 minutes, and separate the oil and water;

Abstract

The invention discloses a degumming technology of fragrant oil-tea camellia seed oil. The degumming technology includes the following steps that 1, fragrant oil-tea camellia seed crude oil is poured to a degumming tank, a citric acid solution is added, and the mixture is stirred and subjected to an acid reaction to separate oil foots in the oil; 2, the oil-tea camellia seed oil subjected to oil foot separation is washed for the first time; 3, the oil-tea camellia seed oil subjected to oil water separation is washed for the second time; 4, the oil-tea camellia seed oil washed for the second time is poured to a vacuum drying tank and dried; meanwhile, a small amount of N2 is sprayed for writhing, and then filtering is carried out through dried filter paper. Compared with the prior art, the problem that the fragrant oil-tea camellia seed oil is poor in fragrance is solved; as the degumming temperature is low, losses of beneficial ingredients are small, and the quality and the fragrance of the tea oil are guaranteed; as the low-temperature vacuum method and the nitrogen writhing method are adopted, residual moisture is effectively removed, the transparency of the degummed oil-tea camellia seed oil is better, and the aim of the degumming technology is achieved.

Description

technical field [0001] The invention relates to a degumming method, in particular to a degumming process of fragrant camellia oleifera seed oil. Background technique [0002] The existing degumming process of Camellia oleifera seed oil imitates the processing technology of bulk oil, specifically: heating the crude camellia seed oil to about 85°C, adding 85% phosphoric acid and mixing the crude oil evenly, and continuously stirring for about 45 minutes; Water, salt water or caustic soda, react for about 20 minutes, and separate the gum or soapstock in the oil; the separated oil is washed with hot water at about 95°C, and after the oil and water are separated, it is dried in a vacuum dryer; after the dry oil is winterized , filter, and pass the inspection to be the finished product. [0003] However, because the bulk oil degumming process is adopted, the degumming is not carried out according to the characteristics of the oil, so that the nutrient content of the oil is lost, ...
