Study On The Instant And Steady-state Technology Of Lycium Chinense Medicinal Parts

Lycium chinense is a precious traditional Chinese medicine and health products,which is rich in proteins,lipids,carbohydrates,crude fiber,Nicole acid.Besides,there are high levels of natural active substances,such as Lycium chinense polysaccharides,carotenoids,betaine,flavonoids and other health efficacy.Lycium chinense flavonoids,carotenoids and other functional factors are extremely sensitive to light,temperature,humidity and other conditions,they are easy to denaturation and reducing the medicinal value without using certain protective measures.In this paper,the Lycium chinense pigment as the main indicator,Lycium chinense slurry was prepared by soaking,beating,sieving,enzymatic hydrolysis and a series of pre-treatment,medlar emulsion was spray-dried Lycium chinense solid product was prepared under the action of the stabilizer and the wall material——Lycium chinense microencapsulated powder,to extend the retention period of the medicinal ingredients and the range of application.and the evaluation method including Lycium chinense stability of microencapsulated powder,instant and absorbency are established on this basis.The main results are as follows:1.The experimental results shows that Lycium chinense slurry enzymatic hydrolysis rate can reach 8.9%by the treatment of 0.15%cellulose at 50℃ for 45 min and pH 4.8.2.Lycium chinense emulsion preparation process,emulsifying temperature of 50℃,emulsification time.of 70 min,the homogeneous pressure 35 MPa,Lycium chinense slurry is in good condition.The ’best formula of the compound emulsion stabilizer are YN1 adding amount of 0.23%,YN2 adding amount of 0.58%and YN3 is 0.88%.Gum arabic and Maltooligosugars composite wall material ratio of 1:3,Lycium chinense microencapsulated powder highest yield.3.Spray-dried preparation of microcapsules Lycium chinense powder,Lycium chinense microencapsulated powder pigment content as the main reference index.the best combination of parameters for the inlet air temperature of 160℃,feed rate of 12 r/min,feed concentration of 40%,under this condition the pigment content of products was 38μg/g.4.Assessment Lycium chinense microencapsulated powder,the test results show that when the temperature is 50℃,Lycium chinense microencapsulated powder prepared and can guarantee it to achieve the purpose of the instant,and solution can be maintained with good color;In the 10-day accelerated moisture absorption experiment,Lycium chinense microencapsulated powder moisture content basically stable at 5.0%,and still maintain good liquidity;In the 60-day accelerated test of the stability of the pigment,pigment degradation rate was only 3.0%,This shows that the microencapsulated ensure the Lycium chinense to maintain steady-state condition.
