Probiotic Wolfberry Powder Freeze Dryer

The main process of freeze-drying equipment in the freeze-drying process of active probiotic Lycium barbarum powder is as follows: Picking fresh Lycium barbarum → beating → sterilizing → cooling → inoculation → fermentation → adding protective agent → freeze-drying → packaging.

Studies have shown that the growth and metabolism of lactic acid bacteria will produce lactic acid, exopolysaccharides, antimicrobial peptides, and other substances, which are not only conducive to improving food flavor, but also improve nutritional value and prolong shelf life. Therefore, the use of Lactobacillus Plantarum to ferment wolfberry increases the nutritional value of wolfberry, the taste is more unique and mellow, and the nutrients are more easily absorbed. The lactic acid bacteria in wolfberry can regulate intestinal flora and lower sterol.

The main operating points of the probiotic wolfberry powder freeze dryer:

1. Preparation of fermented wolfberry pulp: select fresh wolfberry with good quality and shape, beat, and sterilize at 102°C for 20 minutes, after cooling, the inoculum is 1/10,000, culture and ferment for 16 hours, and the fermented wolfberry pulp is within 2 hours spare. The fermented wolfberry pulp was resuspended in different protective agents and mixed well;

2. Freeze-drying process parameters: The measured physical parameters of the probiotic fermented wolfberry pulp material are: eutectic point -5.28°C, crystallization point -19.59°C, glass transition temperature -31.82°C, and disintegration temperature about -36°C. According to the established parameters, the pre-freezing temperature of fermented wolfberry pulp was -40 ℃, the pre-freezing time was 4 h, and the temperature in the sublimation drying stage was -45 ℃. The best compound protective agent combination is: 20% maltodextrin, 14% lactose, 6% trehalose. The sublimation drying temperature of the sample after compounding was -30°C. Probiotic fermented Lycium barbarum freeze-dried powder has a water content of less than 3%, good color, strong rehydration, and good product quality.
