Problems solved by technology

Although this process solves the concentration problem of camellia oleifera saponin to a certain extent, the process is complicated, and there are a small amount of calcium ions in the water phase after treatment, which will affect the quality of camellia oleifera seed oil by water enzymatic method, and cannot reach the recycling of water phase the goal of

Embodiment 1

[0039] The method for extracting camellia oleifera seed oil, camellia oleifera saponin and camellia oleifera seed meal feed from camellia oleifera seed kernel comprises the following steps:

[0040] (1) Grinding the camellia seed kernels into a slurry, adding water to the camellia seed kernel slurry, the amount of water added is 1.5-5 times the weight of the camellia seed kernels, preferably 1.5-3 times, more preferably 1.9-2.2 times, more preferably 1.9 times, extract at 70-90°C, more preferably 80-90°C, for 1.5-3.5h, preferably 3h, and obtain crude tea seed oil, process water and A wet residue after centrifugation;

[0041] (2) Extract A wet residue with alcohol water at 50-73°C for 0.5-3 hours, and separate A alcohol water and B wet residue;

[0042] (3) Extract the B wet residue obtained in step (2) with alcohol water for 0.5-3 hours at 50-75°C, and separate B alcohol water and C wet residue; return B alcohol water to A wet The slag is used as the alcohol-water solution f...

Abstract

The invention relates to a method for extracting camellia oleifera seed oil, sasanqua saponin and camellia oleifera seed meal feed from camellia oleifera seed kernels. The method includes the steps that camellia oleifera seed oil is extracted by means of an aqueous phase, then sasanqua saponin in residues is extracted by means of ethyl alcohol solutions with gradually increased concentrations in a reverse extraction mode, and remaining residues are camellia oleifera seed meal feed. By means of the method, the oil extraction rate can reach 93-95%, and the purity of the obtained sasanqua saponin is higher than 60%. The unique fragrance of the camellia oleifera seed oil can be kept, and it is also guaranteed that fat-soluble components in the camellia oleifera seed kernels are fully maintained in the camellia oleifera seed oil. Ethyl alcohol used in the method is in a food grade, safe, free of toxin and capable of being recycled. Extraction water in use can be recycled through regeneration, no sewage or waste residues are discharged in the whole extraction process, and production application prospects are very wide.

Description

technical field [0001] The invention belongs to the technical field of agricultural resource utilization. The invention relates to a method for extracting camellia oleifera seed oil, camellia oleifera saponin and camellia oleifera seed meal feed from camellia oleifera seed kernel. Background technique [0002] Camellia seed (Oil-Camellia seed) is a unique woody oil plant in China. It is mainly produced in Hunan, Jiangxi, Guangxi and other provinces and regions, and the national annual output of camellia oleifera seeds is 600,000-800,000 tons. The oil content of camellia oleifera seed is 18%-35%, and the oleic acid content in camellia oleifera seed oil is between 74%-85%, which is higher than that of olive oil. Unrefined camellia oleifera seed oil is rich in carotenoids, camellia saponins, tea poly Functional ingredients such as phenol, squalene and oil-soluble vitamins. Camellia oleifera seed contains 6%-11% protein, among which the essential amino acid is rich in content...
