The lipolytic effect of powdered scallop shells was estimated in vitro and in vivo. The scallop shells consisted of 98% calcium carbonate and 2% organic compounds, the extracted organic components promoted lipolysis in 3T3-L1 adipocyte cells.
Male Wistar rats were fed on an experimental diet containing either the scallop shell powder or calcium carbonate (control) for 28 d. Feeding the scallop shell powder resulted in a decrease in body weight and in the weight of white adipose tissue. While the organ weights of the liver, kidney, testis, pancreas, and spleen, and of the brown adipose tissue relative to the body weight were no different between the scallop shell powder diet and control diet, the white adipose tissue weight relative to the body weight significantly decreased in the rats fed on the scallop shell powder. The glycerol concentration in the serum increased in the rats fed on the scallop shell powder, suggesting that this promoted lipolysis in the adipose tissue. These results show that the organic components in the scallop shells induced the decrease in weight of the adipose tissue due to the promotion of lipolysis.
