摘要:

比较分析鱼菜共生养殖、纯投料养殖2 种养殖模式奥尼罗非鱼的肌肉营养成分、感官特性、理化特性、氨 基酸组成及含量。结果显示:2 种养殖模式下罗非鱼的水分、粗脂肪、粗灰分和总糖含量之间无显著差异,而粗蛋 白的含量差异显著;感官评定中,2 种养殖模式下的罗非鱼的鲜味存在显著差异,而口感、嫩度及可接受值差异均 不显著;理化指标中,2 种养殖模式的罗非鱼最终pH值、熟肉率和蒸煮损失均无显著差异,持水性、滴水损失、肌 内脂肪、肌原纤维断裂指数、肌红蛋白含量有显著差异;肌肉中检测到18 种常见氨基酸,天冬氨酸、脯氨酸、精氨 酸的含量差异显著(P<0.05),其他氨基酸含量无显著差异(P>0.05);2 种养殖模式的罗非鱼必需氨基酸总量分 别为22.49%(鱼菜共生模式)和22.45%(纯投料模式),无显著差异;鱼菜共生模式养殖的罗非鱼中鲜味氨基酸总 量显著高于纯投料模式;甜味氨基酸总量分别为45.13%(鱼菜共生模式)和51.18%(纯投料模式),无显著差异。

Abstract:

A comparative analysis of muscle nutrients, sensory characteristics, physical and chemical characteristics
and amino acid composition was carried out on tilapias (Oreochromis niloticus × Oreochromis aureus) cultured under
aquaponics mode and pure feeding mode. Results showed that there was no significant difference in the contents of water,
crude fat, crude ash and total sugar, but significant difference in the contents of crude protein was observed. In the sensory
evaluation, significant difference was observed in umami, although there was no significant difference in taste, tender or
consumer acceptance. There was no significant difference in pH, cooking yield or cooking loss rate between the two modes,
but significant difference in water loss rate, drip loss rate, intramuscular fat, myofibril fracture index and myoglobin existed.
Among 18 common amino acids detected, the contents of Asp, Pro and Arg in muscles were significantly different between
both modes (P < 0.05). There was no significant difference in other amino acids (P > 0.05). The contents of essential
amino acids in tilapias under aquaponics mode and pure feeding mode were 22.49% and 22.45%, respectively, showing no
significant difference. The content of umamiamino acids in tilapias under aquaponics mode was significantly higher than that
observed with pure feeding (P < 0.05). There was no significant difference (P > 0.05) in the content of sweet amino acids,
with abundance of 45.13% (aquaponics mode) and 51.18% (pure feeding mode).
