摘要

Six green algae products and 6 blue-green algae products sold in Taiwanese markets were tested to determine their chemical and microbiological quality. It was found that the average values of the proximate compositions of the green algae products and blue-green algae products were 40.78% and 57.36% protein, 14.28% and 16.57% lipids, 7.79% and 8.07% ash, 6.98% and 7.15% moisture, and 30.17% and 10.79% carbohydrates, respectively. The average carbohydrate value of the green algae products was significantly (p＜0.05) higher than that of the blue-green algae products. In contrast, the average protein level in the green algae products was significantly lower than that of the blue-green algae products, except for BH-C and BH-S products. Among them, only one sample of green algae products and one sample of blue-green algae products had an aerobic plate count (4.94 and 5.30 log CFU/g, respectively) greater than the Taiwanese regulatory standard limit of 4.70 log CFU/g. None of these samples contained total coliform or Escherichia coli. The amounts of pheophorbide a and heavy metals in all samples were below Taiwanese regulatory levels. Almost all of these tested samples were acceptable products based on Taiwanese regulatory standards for chemical and microbiological quality.
