Problems solved by technology

The tea seed polysaccharide extraction method reported in the literature is basically to extract the mixture of tea saponin and tea seed polysaccharide first, and then separate it. The polysaccharide content can reach more than 70%, but the operation is complicated and the extraction cost is high.
Some problems in the extraction and use of the existing polysaccharide biologically active substances affect its large-scale application. First, there are certain problems in the source of raw materials. The raw materials are basically Chinese herbal medicines and fungi products, and the price is relatively low. Expensive. Second, the extraction yield is low, the utilization rate of raw materials is low, and the production cost is high.
The third is that the content of the extract is low, so the product is used in a large amount and the cost of use is high
There are few reports on the application of Camellia oleifera seed polysaccharides extracted from Camellia oleifera cake after oil extraction

Embodiment 1

[0026] 1000g defatted camellia oleifera cake, soaked in 6000ml 70% (v / v) ethanol solution three times at 30°C, each time for 30 minutes, combined soaking liquid, vacuum concentration, spray drying to obtain 78 grams of product with tea saponin as the main component; The residue after the soaking process was soaked three times at 40° C. with 6000 ml of 50% ethanol for 30 minutes each time. The soaking liquid was combined, concentrated in vacuum, and spray-dried to obtain 91 grams of the product of camellia oleifera polysaccharide as the main component.

Embodiment 2

[0028] 1000g defatted camellia oleifera cake, 4000ml 98% (v / v) methanol solution, soaked three times at 40°C, each time for 30 minutes, combined soaking liquid, concentrated in vacuo, spray-dried to obtain 85g of tea saponin with a content of 82%; The soaked residue was soaked three times at 40° C. with 4000 ml of 30% ethanol, each time for 30 minutes. The soaking liquids were combined, vacuum concentrated, and spray-dried to obtain 88 g of Camellia oleifera polysaccharides with a sugar content of 68%.

Embodiment 3

[0030] 1000g defatted camellia oleifera cake, 5000ml 80% (v / v) methanol solution, soaked three times at 35°C, each time for 30 minutes, combined the soaking liquid, vacuum concentrated, spray-dried to obtain 83g of tea saponin with a content of 73%; The residue after soaking was soaked three times at 40° C. with 5000 ml of 45% ethanol for 30 minutes each time. The soaking liquids were combined, vacuum concentrated, and spray-dried to obtain 95 g of Camellia oleifera polysaccharides with a sugar content of 71%.

Abstract

The invention provides a production method of camellia seed polysaccharide, which relates to the technical field of feed additives and agricultural waste utilization. The method comprises: subjecting camellia dregs powder after oil extraction to solvent degreasing treatment; soaking degreased cake powder in 70 to 99 percent alcohol, concentrating and drying soak solution and obtaining tea saponin; and soaking tea seed cake powder after tea saponin extraction in ethanol, concentrating and drying the soak solution and obtaining the camellia seed polysaccharide. The camellia seed polysaccharide can be directly used as animal feed additives of pigs, cattle, chickens and other poultry. Compared with the prior art, the method has the characteristics of simplicity, high extraction yield, high purity, high utilization rate of raw materials, wide raw materials source, capability of mass production, low production cost, capability of changing waste into valuables and benefit for environmental protection. The camellia seed polysaccharide can be applied as the animal feed additives of pigs, cattle, chickens and other poultry, thereby having significant social and economic benefit.

Description

technical field [0001] The invention relates to the technical field of feed additives and agricultural waste utilization. Background technique [0002] In recent years, my country's animal breeding industry has become large-scale and intensive, and feed additives, especially antibiotic feed additives, are widely used. Feed additives can improve the health status of livestock and poultry, improve fecundity and production performance, and improve feed conversion rate and utilization efficiency of nutrients by adjusting feed intake and improving the digestibility of nutrients and energy. Feed additives have become an indispensable substance for animal growth, breeding and disease prevention. The use of feed additives has played a very important role in promoting the development of the breeding industry. However, the use of a large number of chemical veterinary drugs and antibiotic feed additives has brought obvious negative impacts, which not only affect the normal development...
