Abstract

This study investigated the effects of dietary Periplaneta americana water extract (PAWE) supplementation (0, 1, 2, and 4 g/kg) on the chemical composition, antioxidant capacity, and meat quality in Nile tilapia. The results showed that the extract improved weight gaining rated of Nile tilapia (Oreochromis niloticus). Meanwhile, dietary PAWE decreased lactate content, glycolytic potential, centrifugal water loss, and cooking loss, and enhanced muscle pH, protein content, total sulfhydryl content and meat color in Nile tilapia muscle. Dietary PAWE also improved the total antioxidant capability with enhanced superoxide dismutase, catalase, and glutathione peroxidase activities and lowered contents of reactive oxygen species, and lipid and protein oxidation products (i.e. thiobarbituric acid reactive species and protein carbonylation). Moreover, dietary PAWE enhanced the contents of flavor amino acids, total amino acids, adenosine monophosphate, and 5′-inosine monophosphate with enhanced the taste indicators (umami, richness and sweetness). In addition, PAWE supplementation improved myofiber growth and muscle protein deposition likely by activating of the IGFs/PI3K/Akt/TOR/S6K1/4E-BP1 pathway, contributing to the enhanced growth performance of Nile tilapia. The optimal dietary PAWE requirement for maximum growth and muscle protein was approximately 3 g/kg. Together, PAWE is a promising natural food additive that enhances muscle quality and nutritional value of Nile tilapia.

日粮中的美洲长尾鲈水提取物对尼罗罗非鱼的生长、化学成分、肌肉抗氧化状态和肉质的影响

本研究调查了日粮中添加美国罗非鱼水提取物（PAWE）（0、1、2 和 4 克/千克）对尼罗罗非鱼化学成分、抗氧化能力和肉质的影响。结果表明，该提取物提高了尼罗罗非鱼（Oreochromis niloticus）的增重率。同时，膳食虾青素降低了尼罗罗非鱼肌肉中的乳酸含量、糖酵解潜能、离心失水和蒸煮损失，提高了肌肉的 pH 值、蛋白质含量、总巯基含量和肉色。通过提高超氧化物歧化酶、过氧化氢酶和谷胱甘肽过氧化物酶的活性，降低活性氧、脂质和蛋白质氧化产物（即硫代巴比妥酸活性物和蛋白质羰基化）的含量，膳食 PAWE 还提高了总抗氧化能力。此外，膳食虾青素还能提高风味氨基酸、总氨基酸、单磷酸腺苷和单磷酸 5′-肌苷的含量，并增强口感指标（鲜味、浓味和甜味）。此外，补充 PAWE 可能通过激活 IGFs/PI3K/Akt/TOR/S6K1/4E-BP1 通路，改善肌纤维生长和肌肉蛋白质沉积，从而提高尼罗罗非鱼的生长性能。最大生长和肌肉蛋白的最佳日粮 PAWE 需求量约为 3 克/千克。总之，PAWE 是一种很有前景的天然食品添加剂，可提高尼罗罗非鱼的肌肉质量和营养价值。

期刊介绍： The Journal of Insects as Food and Feed covers edible insects from harvesting in the wild through to industrial scale production. It publishes contributions to understanding the ecology and biology of edible insects and the factors that determine their abundance, the importance of food insects in people’s livelihoods, the value of ethno-entomological knowledge, and the role of technology transfer to assist people to utilise traditional knowledge to improve the value of insect foods in their lives. The journal aims to cover the whole chain of insect collecting or rearing to marketing edible insect products, including the development of sustainable technology, such as automation processes at affordable costs, detection, identification and mitigating of microbial contaminants, development of protocols for quality control, processing methodologies and how they affect digestibility and nutritional composition of insects, and the potential of insects to transform low value organic wastes into high protein products. At the end of the edible insect food or feed chain, marketing issues, consumer acceptance, regulation and legislation pose new research challenges. Food safety and legislation are intimately related. Consumer attitude is strongly dependent on the perceived safety. Microbial safety, toxicity due to chemical contaminants, and allergies are important issues in safety of insects as food and feed. Innovative contributions that address the multitude of aspects relevant for the utilisation of insects in increasing food and feed quality, safety and security are welcomed.
