Marine salts enriched with biological prods. for food and cosmetic use - prepd. by fermentation using phytoplankton cells

摘要

The salts are prepd. by adding nutritive substances, such as nitrates or phosphates, to sea water in a vessel, then inoculating the mixture with phytoplankton cells. After 10 days when the number of cells has considerably increased the culture medium is filtered and the filtrate is evaporated and dried under vacuum at 40-50 degrees C. The product is used wither (a) as bath salts or in cosmetic products or (b) as a food supplemtn. As (a) it has a sea odour, a soft consistency and is nutritive to the epidermic cells; and (b) it is beneficial as a result of the synthesised substances such as vitamins that it contains. The phytoplankton cells are pref. diatom, specifically Chaetoceras teres and/or Asterionella japonica. In the prepn. the culture is pref. filtered first through nylon mesh of 100 mu dia. and then through material of 10-0.5 mu mesh dia.
