Abstract

The invention discloses a preparing method of a Lycium ruthenicum juice. The method comprises the steps of 1, selecting fresh Lycium ruthenicum, conducting grinding through a colloid mill, and adjusting the pH value to obtain a colloid mill ground solution; 2, adding chitin or chitosan into the colloid mill ground solution, clarifying at a temperature of 20-50 DEG C for 20-80 min, adding 0.2-2 g the chitin and the chitosan in every Litre of the colloid mill ground solution, conducting centrifugation to obtain a liquid supernatant, and concentrating to obtain a concentrated solution; 3, adding citric acid, malic acid and a sweetening agent into the concentrated solution and mixing the solution evenly; 4, filtering through a ceramic membrane, conducting sterilization and filling to obtain the Lycium ruthenicum juice. The Lycium ruthenicum juice has a good antioxidant function and excellent color, aroma and taste, an easily acceptable mouth feeling, good health care value and application prospect.

Description

technical field [0001] The invention relates to black fruit wolfberry juice and a preparation method thereof. Background technique [0002] Lycium ruthenicum Murr. is the mature fruit of Lycium genus Solanaceae. It is a perennial shrub distributed in my country's Qinghai, Gansu, Inner Mongolia, Ningxia, Xinjiang, Tibet and northern Shaanxi Loess Plateau; it belongs to the typical desert Saline plants. Lycium barbarum fruit contains anthocyanins, total polyphenols, polysaccharides, amino acids, vitamins, flavonoids, alkaloids, mineral elements, etc. Oxidation, anti-aging and menstruation and other biological activities. [0003] Chen Chen, "Study on the Production Technology of Lycium Barbarum Fruit Juice", Food and Fermentation Science and Technology, Issue 2, 2011, Volume 47 (Total Issue 162) discloses a method for preparing black fruit juice using colloid mill, high-pressure homogenization, and membrane separation. The method of fruit wolfberry juice. The antioxidant ac...
