Milk containing low-temperature freeze-dry micropowder phycocyanin and preparation method thereof

Abstract

The invention discloses a milk containing low-temperature freeze-dried micro-powder phyeoeyanin and a preparation method thereof; the method comprises the following steps of: A: the cell wall of spiral seaweed is destroyed in the environment of low temperature and super high pressure; the spiral seaweed which is sorted, cleaned, centrifugated and dehydrated is processed at the pressure of 500 to 1000MPa, the temperature is controlled within 20 DEG C and the time lasts for 15 minutes, thus destroying the cell wall of the spiral seaweed; B: freeze-dried technology: the spiral seaweed balls which are sterilized by super high pressure under the temperature of minus 5 DEG C is frozen to ice in half an hour, and then the water of the spiral seaweed balls is sublimated to water steam at the temperature of 15 to 20 DEG C and under the vacuum condition with mercury column of 40 to 50mm and then is discharged; and the water content of the spiral seaweed balls is guaranteed to be below 3 percent after being processed; C: the processing of the micro-powder: coarse grinding is applied to the spiral seaweed which is freeze-dried, and the micro-powder of the spiral seaweed with the diameter of 3 to 5 Mum is prepared; D: a physical wall-destroying method in the environment of low temperature and super high pressure is completely adopted, thus keeping the bioactivity of various matters in the spiral seaweed completely.

Problems solved by technology

[0004] At present, most spirulina products on the market use chemical extraction of phycocyanin as an index or use spray drying method. The disadvantage is that high temperature will destroy the active and active ingredients, destroying spirulina phycocyanin, spirulina polysaccharide, calcium and zinc. , selenium, potassium, chlorophyll, β-carotene, phycocyanin and other spirulina-specific active substances, which waste the nutrition of spirulina and are not conducive to the health of consumers
