우렁이 생체에 대하여 일반성분을 분석한 결과 수분함량은 74.8%, 조단백질 12.7% 및 조지방 0.6%의 함량을 보여 고단백 저지방의 식품재료로써 그 이용 가능성을 찾을 수 있었다. 또한 우렁이를 껍질, 내장 및 근육 3부분으로 분류하여 무기성분을 분석한 결과 우렁이에 함유되어 있는 주요 무기성분으로는 P, Ca, Mg 및 Na이었으며, 그 중 껍질 및 내장, 근육모두에서는 Ca이 가장 많이 함유되어 있어 중요한 Ca 급원으로 이용 가능하다.

This study was carried out to investigate the nutritive components of apple snail, Cipangopaludina chinensis malleata, with different parts such as shell, viscera and muscle. The average content of moisture, crude fat, crude protein, carbohydrate and ash in the muscle of apple snail were and respectively. The shell of apple snail contained above 97% ash. Amino acid analysis showed that the major amino acids of muscle were in order of arginine (31.7%), alanine (21.2%) and glutamic acid (7.1%) among total 17 amino acids, while those of viscera were tyrosine (24.5%) and alanine (12.4%) and arginine (11.4%). On the other hand, the major minerals of muscle were P (8.12 mg%), Ca (42.27 mg%), and Mg (4.04 mg%), while those of shell were Ca (54.66 mg%), P (3.9 mg%), and Na (2.33 mg%). The saturated fatty acid in different pare of apple snail was shown to be 1.6% in muscle, 5.3% in viscera, and 4.2% shell. These results imply that apple snail can be used as a good nutritional source with high protein and low fat content.
