Embodiment Construction

[0016] Based on the protective agent used in the preservation of free bacteria by the predecessors, combined with the results of the study on the factors affecting the strength of the capsule, the protective solution based on normal saline was selected, and some sugar, glycerin and calcium carbonate were added to it. , firstly carry out single factor experiment, based on normal saline, add different contents of glucose (1%, 3%, 5%, 7%, 9%), sucrose (1%, 3%, 5%, 7%) , 9%), glycerin (5%, 10%, 15%, 20%) and calcium carbonate (0.05%, 0.1%, 0.2%, 0.3%, 0.4%), research these factors on the bacterium activity in the capsule and capsule Intensity of influence. Prepare the storage protection solution according to the design. After sterilizing at 121°C for 20 minutes, put the prepared high-density microcapsule starter into the storage protection solution and store it at 4°C for one month. The capsules are broken by chemical capsule breaking, and then The number of bacteria in the capsu...

Abstract

The invention relates to a formula of high-efficiency protection liquid for the storage of a microcapsule leaven, which belongs to the technical field of biological engineering. The protection liquid is prepared from the following components in the optimum formula ratio: 0.9% of sodium chloride, 3% of glucose, 5% of cane sugar, 10% of glycerol, 0.2% of calcium carbonate and the like. The invention can solve the storage problem of the microcapsule leaven and effectively prolongs the service life of the leaven.

Description

1. Technical field [0001] The invention relates to a high-efficiency microcapsule fermentation agent storage protection liquid formula, which belongs to the technical field of bioengineering. 2. Background technology [0002] With the rapid development of my country's fermented food industry, new requirements have been put forward for the starter industry, and the demand has been increasing year after year. At present, most of the large-scale dairy processing enterprises in my country adopt the direct-input yogurt starter imported from abroad, which is stable in quality, easy to produce, and the cell density can reach 10 11 cfu / g, however expensive and expensive to produce. Therefore, when small and medium-sized dairy processing enterprises produce yogurt, they can only use traditional subculture yogurt starter with low cost. Due to the pollution in the subculture process and the imbalance of various bacterial species, the product quality is poor. Microcapsule starter is ...
