| 摘 要： | 渔光一体养殖模式是一种采用水下养殖、水上发电的新兴环保养殖模式。本研究比较渔光一体(PM)与普通池塘养殖模式(CM)中华绒螯蟹(Eriocheir sinensis)在基本营养成分、感官评价、滋味品质等方面的差异。测定了体肉中的游离氨基酸和呈味核苷酸,计算滋味活度值 TAV及味精当量 EUC,并与人工感官、智能感官的评测结果关联,对滋味品质进行综合评价。结果表明,PM组雌蟹体肉中粗蛋白、粗脂肪显著高于CM组 (P＜0.05),雄蟹则无差异；PM组雌蟹体肉具有较强的鲜味、甜味强度,CM组雄蟹体肉具有较强的咸味、鲜味强度；PM组的总游离氨基酸、甜味游离氨基酸含量显著高于CM组 (P＜0.05)；PM组中华绒螯蟹体肉中味精当量均大于CM组。渔光一体养殖模式能使中华绒螯蟹体肉具有更好的营养及鲜甜滋味。

| Abstract: | The photovoltaic fishery breeding mode is a new environmental protection mode that combines pond aquaculture and photovoltaic power generation. In this study, we compared the differences in basic nutrition composition, sensory evaluation, and taste quality in the meat of Chinese mitten crab (Eriocheir sinensis) between the common pond breeding mode and photovoltaic fishery breeding mode. The free amino acids and taste nucleotides in meat were determined, and the taste activity value was calculated. Taste activity value (TAV) and equivalent umami concentration (EUC) were associated with artificial and electronic senses to comprehensively analyze the taste quality. The results showed that the crude protein and crude lipid content in meat of female crabs in group PM were significantly higher than those in group CM (P < 0.05), but there were no differences in male crabs. The meat of female crab in group PM had strong umami and sweet taste intensity, while the meat of male crab in group CM had strong saltiness and umami taste intensity. The contents of total free amino acids and sweet free amino acids in group PM were significantly higher than those in group CM (P < 0.05). The EUC in the meat of Chinese mitten crab in group PM was higher than that in group CM. The photovoltaic fishery breeding mode can make the meat of Chinese mitten crab have better nutrition and sweet taste. |
