Abstract The application of Former Food Products (FFPs) as feed ingredients is already documented in swine, as well as their beneficial nutritional value. To date, FFPs extra-nutritional bioactive effect in feed has not been elucidated. Therefore, the aim of the present study was to investigate and compare the total phenolic content and antioxidant capacity (AOC) in six samples of FFPs extracted by different solvent systems. After methanol and acetone extraction, total phenolic content and AOC were determined in FFPs and wheat sample (CTR) using Folin–Ciocalteu and 2,2'-azinobis (3-ethylbenzothiazoline 6-sulfonic acid)-ABTS assay, respectively. Results demonstrated that FFPs samples were characterised by an average amount of total phenolic content of 129.3 ± 15.1 mg tannic acid equivalents (TAE)/100g in methanol extracts and 156.4 ± 25.8 mg TAE/100g in acetone extracts. Whereas, the ABTS assay revealed that FFPs showed also anAOC of 138.0 ± 14.3 mg Trolox Equivalent (TE)/100 g in methanol extracts and 173.3 ± 18.8 mg TE/100 g in acetone extracts. Former Food Products represent relevant sources of phenols and antioxidant compounds, which can be beneficial for animal health. Highlights Former Food Products (FFPs) reprocessing is a way to convert food losses into ingredients for animal diets; Valuable content of total phenolic compounds and notable antioxidant capacity were observed in FFPs after extraction with methanol and acetone; FFPs demonstrated to be a source of bioactive compounds with extra-nutritional activities which can be beneficial for animal health.

用作替代饲料成分的原食品的总酚含量和抗氧化能力

摘要 原食品 (FFP) 作为饲料成分在猪中的应用及其有益的营养价值已被记录在案。迄今为止,尚未阐明 FFP 在饲料中的营养外生物活性作用。因此,本研究的目的是调查和比较不同溶剂系统提取的六种 FFP 样品的总酚含量和抗氧化能力 (AOC)。甲醇和丙酮提取后,分别使用 Folin-Ciocalteu 和 2,2'-azinobis(3-乙基苯并噻唑啉 6-磺酸)-ABTS 测定法测定 FFP 和小麦样品 (CTR) 中的总酚含量和 AOC。结果表明,FFP 样品的特征在于,甲醇提取物中的平均总酚含量为 129.3 ± 15.1 mg 单宁酸当量 (TAE)/100g,156.4 ± 25。8 mg TAE/100g 丙酮提取物。而 ABTS 分析表明,FFP 在甲醇提取物中的 AOC 也为 138.0 ± 14.3 mg Trolox 当量 (TE)/100 g,在丙酮提取物中的 AOC 为 173.3 ± 18.8 mg TE/100 g。前食品是酚类和抗氧化化合物的相关来源,对动物健康有益。亮点 原食品 (FFP) 再加工是将食物损失转化为动物饮食成分的一种方式;用甲醇和丙酮提取后,FFPs 中总酚类化合物含量高,抗氧化能力显着;FFP 被证明是具有额外营养活性的生物活性化合物的来源,这对动物健康有益。3 mg Trolox 当量 (TE)/100 g 甲醇提取物和 173.3 ± 18.8 mg TE/100 g 丙酮提取物。前食品是酚类和抗氧化化合物的相关来源,对动物健康有益。亮点 原食品 (FFP) 再加工是将食物损失转化为动物饮食成分的一种方式;用甲醇和丙酮提取后,FFPs 中总酚类化合物含量高,抗氧化能力显着;FFP 被证明是具有额外营养活性的生物活性化合物的来源,这对动物健康有益。3 mg Trolox 当量 (TE)/100 g 甲醇提取物和 173.3 ± 18.8 mg TE/100 g 丙酮提取物。前食品是酚类和抗氧化化合物的相关来源,对动物健康有益。亮点 原食品 (FFP) 再加工是将食物损失转化为动物饮食成分的一种方式;用甲醇和丙酮提取后,FFPs 中总酚类化合物含量高,抗氧化能力显着;FFP 被证明是具有额外营养活性的生物活性化合物的来源,这对动物健康有益。亮点 原食品 (FFP) 再加工是将食物损失转化为动物饮食成分的一种方式;用甲醇和丙酮提取后,FFPs 中总酚类化合物含量高,抗氧化能力显着;FFP 被证明是具有额外营养活性的生物活性化合物的来源,这对动物健康有益。亮点 原食品 (FFP) 再加工是将食物损失转化为动物饮食成分的一种方式;用甲醇和丙酮提取后,FFPs 中总酚类化合物含量高,抗氧化能力显着;FFP 被证明是具有额外营养活性的生物活性化合物的来源,这对动物健康有益。
