The study assesses the antioxidant activity, total phenolic content, total flavonoids content and lipophilic pigments (β-carotene, chlorophyll a, chlorophyll b) content in homemade and marketed fruit and vegetable whey beverages and fruit and vegetable mousses. All of the tests were performed using spectrophotometric methods. The highest polyphenol content was found in the homemade green whey beverage W1G (541.95 mg/100 g) and the lowest in the market green whey beverage W2G (46.18 mg/100 g). In the fruit and vegetable mousses under study, the highest content of polyphenolic compounds was determined in the red mousse R3 (76.41 mg/100 g). The highest content of flavonoids was observed in the homemade orange whey beverage W1O (63.06 mg/100 g) and in the green mousse G2 (69.80 mg/100 g). The values of the antioxidant activity of whey beverages and mousses varied depending on the composition. The highest content of β-carotene was identified in homemade orange whey beverage (4.36 mg/100 g) and in orange mousses (in range 1.10-2.24 mg/100 g), while chlorophylls a and b-in homemade green whey beverage W1G (3.00 mg/100 g and 1.31 mg/100 g respectively) and in green mousses (chlorophyll a in range 0.54 to 1.42 mg/100 g and chlorophyll b in range 0.13 to 0.32 mg/100 g).
本研究评估了自制和市售果蔬乳清饮料和果蔬慕斯中的抗氧化活性、总酚含量、总类黄酮含量和脂溶性色素（β-胡萝卜素、叶绿素 a、叶绿素 b）含量。所有测试均使用分光光度法进行。自制的绿色乳清饮料 W1G 中的多酚含量最高（541.95mg/100g），市售绿色乳清饮料 W2G 中的多酚含量最低（46.18mg/100g）。在所研究的果蔬慕斯中，红色慕斯 R3 中的多酚含量最高（76.41mg/100g）。自制的橙汁乳清饮料 W1O 和绿色慕斯 G2 中的类黄酮含量最高（63.06mg/100g 和 69.80mg/100g）。乳清饮料和慕斯的抗氧化活性值因成分而异。自制的橙汁乳清饮料（4.36mg/100g）和橙汁慕斯（范围为 1.10-2.24mg/100g）中的β-胡萝卜素含量最高，而叶绿素 a 和 b-则在自制的绿色乳清饮料 W1G（分别为 3.00mg/100g 和 1.31mg/100g）和绿色慕斯（叶绿素 a 范围为 0.54-1.42mg/100g，叶绿素 b 范围为 0.13-0.32mg/100g）中含量最高。
