Farming of trout requires a finishing diet containing pigments such as astaxanthin and canthaxanthin so that they may achieve a pink tissue coloration similar to that of wild trout. The production of synthetic pigments is not enough so that the requirements of the aquaculture industry are not met, besides having a high cost. Thus, the objective of the present study was to evaluate the deposition of saponified and esterified chili (Capsicum annuum) extracts in the skin and muscle of rainbow trout (Oncorhynchus mykiis). The experiment consisted of three treatments with the inclusion in the finishing diet of saponified and esterified chili extracts and of astaxanthin, respectively. Each treatment was carried out with 150 organisms with an average weight of a 150 g and done in duplicate. The results showed that both the saponified and esterified chili extracts pigmented the skin and muscle of rainbow trout, although the pigmentation effect was less red than that produced by the astaxanthin control.
养殖鳟鱼需要一种含有虾青素和角黄素等色素的育成饲料，以便它们能呈现出与野生鳟鱼相似的粉红色组织色泽。合成色素的产量不足以满足水产养殖业的需求，而且成本高昂。因此，本研究的目的是评估皂化和酯化辣椒（辣椒属）提取物在虹鳟（Oncorhynchus mykiss）皮肤和肌肉中的沉积情况。实验包括三种处理，分别在育成饲料中添加皂化和酯化辣椒提取物以及虾青素。每种处理使用150只平均体重为150克的生物，重复进行两次。结果表明，皂化和酯化辣椒提取物均能使虹鳟的皮肤和肌肉着色，尽管其着色效果比虾青素对照组产生的红色要浅。
