Problems solved by technology

Existing vegetable oil extraction is generally carried out by pressing method, solvent method, extrusion puffing leaching method and aqueous enzymatic method. The residual oil rate in the pressed cake is high (5%~7%, dry basis), the heating temperature is high, and the processing time is high. Long, poor oil and cake quality, serious protein denaturation; solvent method equipment investment is large, the ratio of solvent to embryo is large, the process is complicated, and the use of chemical organic solvents increases its unsafety, and a slight error in operation may easi

Embodiment 1

[0013] Example 1: A process for extracting tea seed oil, tea saponin and protein powder from tea seeds, comprising the following steps: a. The tea seeds are cleaned of impurities and shelled to obtain tea seeds. The tea seeds are dried with hot air and then pulverized through a 10-mesh sieve for the first time, then extruded and puffed, finally dried, and pulverized for the second time through a 60-mesh sieve. ;

[0014] b. Add water and homogenate the tea seeds obtained in step a to obtain a feed liquid, add enzymes to the feed liquid, the enzymes are one or more of pectinase, cellulase and Alcalase 2.4 L protease, pectinase, fiber Sulfase and Alcalase 2.4 L protease were added in sequence, the amount of enzyme was 2%, the ratio of solid to liquid was 1:4, and the enzymolysis was carried out in the ultrasonic treatment device. The ultrasonic wave used by the ultrasonic treatment device was 25kHz, and the power was 40W. Treat once every 30 minutes, and treat 4 times in total...

Abstract

The invention discloses a process for extracting tea seed oil, tea saponin and protein powder from tea seeds. The method comprises the following steps of: removing impurities of the tea seeds, unshelling the tea seeds, carrying out hot air drying and grinding, implementing extrusion treatment, then carrying out drying and grinding again; adding water in the tea seeds to homogenize a slurry to obtain a material liquid, carrying out enzyme killing treatment in an ultrasonic processing device on enzyme in the material liquid after enzymolysis is implemented, carrying out centrifugal separation to obtain oil, an emulsion and an aqueous solution; carrying out demulsification treatment on the emulsion by an aqueous enzymatic method and the centrifugal separation on the emulsion to obtain the oil and the aqueous solution; carrying out degumming, deacidifying, bleaching and deodorization treatments on the oil to obtain the refined tea seed oil; coarsely filtering the aqueous solution, adjusting the pH value, carrying out ultrafiltration through an ultrafiltration membrane to obtain a protein liquid and a filtrate, implementing spray drying on the protein liquid to obtain tea seed protein powder, heating the filtrate and concentrating and filtering by nanofiltration to obtain a tea saponin thick liquid, and then carrying out freeze drying to obtain tea saponin powder. By adopting the way, the acquisition rates of the tea seed oil, the protein powder and the tea saponin can be improved and the purity and quality of product can be enhanced.

Description

technical field [0001] The invention relates to the field of grain and oil processing, in particular to a process for extracting tea seed oil, tea saponin and protein powder from tea seeds. Background technique [0002] The industrial development project of producing tea seed oil with co-production of functional peptides and tea saponin by aqueous enzymatic method has advanced technology and high technological content, and can regenerate tea seeds. At present, the tea seed oil industry is an emerging industry with a huge potential market. Existing vegetable oil extraction is generally carried out by pressing method, solvent method, extrusion puffing leaching method and aqueous enzymatic method. The residual oil rate in the pressed cake is high (5%~7%, dry basis), the heating temperature is high, and the processing time is high. Long, poor oil and cake quality, serious protein denaturation; solvent method requires large investment in equipment, large ratio of solvent to embry...
