The results reported here showed that threshold concentrations of skatole and indole in rice-bran oil for Singaporean consumers were 0.028 μg/g and 0.051 μg/g, respectively, and that skatole and indole levels in subcutaneous fat of pigs can be affected by diet. In Experiment A, 31 female pigs were fed with diets based on plant products only (P) or plant plus animal by-products (AP), with added levels of garlic essential oil from zero to 2.15 g/kg feed. Concentrations of skatole and indole increased with increasing garlic concentration (P < 0.001). In Experiment B, P and AP diets were fed to 47 female pigs with different dietary lipid sources (fish oil, tallow, and a mix of linseed oil and soya oil). Skatole and indole concentrations were higher in backfat of pigs fed with the AP diet (P < 0.05), but were unaffected by the type of lipid.
本研究结果表明，对于新加坡消费者，米糠油中粪臭素和吲哚的阈值浓度分别为 0.028μg/g 和 0.051μg/g，且猪皮下脂肪中的粪臭素和吲哚水平可受饮食影响。在实验 A 中，31 头母猪仅喂食植物性产品（P）或植物性产品加动物副产品（AP）饲料，添加水平为 0 至 2.15g/kg 饲料的大蒜精油。粪臭素和吲哚的浓度随大蒜浓度的增加而增加（P<0.001）。在实验 B 中，将 P 和 AP 饲料喂食给 47 头具有不同膳食脂质来源（鱼油、牛脂和亚麻籽油与大豆油的混合物）的母猪。饲喂 AP 饲料的母猪的背脂中粪臭素和吲哚浓度更高（P<0.05），但不受脂质类型的影响。
