Abstract

The invention relates to a method for controlling microbe indexes in microalgae powder by combination of pasteurization and spray drying and a method for producing microalgae powder. The method comprises the following steps: pasteurizing a microalgae concentrated solution to obtain a sterilized concentrated solution, and drying the sterilized concentrated solution to obtain microalgae powder, thereby controlling the microbe indexes in the microalgae powder (including but not limited to total bacterial count, mold quantity and yeast quantity); and producing the microalgae powder. The method can effectively control the microbe indexes (especially total bacterial count) of the algae powder, and can maximally maintain the activity of the active substances in the microalgae. The method is suitable for but not limited to producing Chlorella, Haematococcus pluvialis, spirulina, Dunaliella, Nannochloropsis oculata, Schizochytrium, Crypthecodinium cohnii and various algae powders, and is hopeful to become a universal production method capable of effectively controlling microbe indexes (especially total bacterial count) in the algae powder.

Description

technical field

[0001] The invention relates to a method for controlling microbial indicators in microalgae powder, especially the total number of colonies, in particular to a method for controlling microbial indicators in microalgae powder, especially the total number of colonies, by coupling pasteurization and spray drying. production. Background technique

[0002] Microalgae grow rapidly, and the cells are rich in protein, Ξ²-carotene, astaxanthin, unsaturated fatty acids (DHA, RHA) and various trace elements, etc., which have great economic development value.

[0003] The crude protein content of microalgae can reach more than 60%, and some microalgae have been developed into health products, food additives, etc.; feeding pets with microalgae can make their hair shiny or feathers more beautiful; using microalgae to feed zooplankton, It also has broad development potential in aquaculture (O.Pulz, W.Gross. Valuable products from biotechnology of microalgae. Appl Microbiol ...
