Vitamin and mineral content of microalgae Phorpyridium and Chlorella and development prospects for food raw materials in Indonesia

Abstract

Porphyridium cruentum is a product of the division of the genus Rhodophyta. It is a single cell that lives or colonizes freely in mucillago. The cells continuously secrete mucillago compounds, forming a capsule that envelops the cells. Mucillago is a sulfate polysaccharide that is soluble in water [1]. Microalgae Chlorella sp. are marine algae that can grow on fresh water and sea water media. This type of algae has a green pigment included in it class Chlorophyceae of the Chlorellaceae family. The goal of this study was to find out how much vitamin and mineral content there was in Phorpyridium and Chlorella cultivated on Conway media. The findings demonstrate that Phorpyridium has a higher vitamin E content than vitamins B1, B2, and B6. ie. 2,4 mg/100 g. Mineral analysis showed that Phorpyridium contained K minerals (45,7 mg/100g), Ca (201 g/100g), Mg (1090 mg/100g), Fe (38,2 mg/kg), Zn (3,45 mg/kg), Se (0,04 mg/kg), and P (2351 mg/kg).. Vitamin analysis of Chlorella show that vitamin B1 in Chlorella higher than Phorpyridium ie.( 3,71 mg/kg). Mineral analysis showed that Chlorella contained K minerals (714 mg/100g), Ca (331 g/100g), Mg (335 mg/100g), Fe (539 mg/kg), Zn (21,7 mg/kg), Se (0,22 mg/kg), and P (2982 mg/kg).
