不同品种百香果果汁营养成分的比较

Assessment of Nutritional Components in Passiflora edulis Juice of Different Cultivars

摘要

摘要: 以百香果常见品种黄金果、台农、紫果1号果汁为原料,用国标法对不同品种百香果果汁蛋白质、粗脂肪、矿物质含量、氨基酸含量等营养物质进行测定。结果表明:黄金果果汁的蛋白质、矿物质含量和总氨基酸含量显著高于台农和紫果1号(p<0.05);台农果汁的总糖含量(7.53±0.06) g/kg、维生素B₂ 0.13 mg/100 g、维生素B₁₂ 0.23 mg/100 g和超氧化物歧化酶活性(238.67±0.92) U/mL最高;紫果1号果汁的总酸含量(42.43±0.26) g/kg,维生素C(13.47±0.12) mg/100 g、维生素B₆ 0.15 mg/100 g和维生素A 0.024 mg/100 g最高。不同品种百香果果汁的营养成分具有一定差异,结合百香果不同品种的营养特点,在百香果产业高附加值保健产品开发和工厂化加工利用时,黄金果是较好的百香果品种选择。

Abstract: Using the national standards methods, the nutrition components of three kinds of Passiflora edulis fruit (Huangjinguo, Tainong and Ziguo No. 1) juices were analyzed and compared. The results showed that the content of total protein, total minerals and amino acids in Huangjinguo fruit juice were significantly higher than the other cultivars (p<0.05). The total sugar (7.53±0.06) g/kg, VB₂ 0.13 mg/100 g, VB₁₂ 0.23 mg/100 g and superoxide dismutase (238.67±0.92) U/mL activity of Tainong were the highest, and the total acid (42.43±0.26) g/kg, V_C (13.47±0.12) mg/100 g, VB₆ 0.15 mg/100 g and V_A content 0.024 mg/100 g of Ziguo No. 1 were higher than the other two cultivars. The nutritional components of three varieties of fruit juice were different. Considering the nutritional characteristics, Huangjinguo was the best cultivar in high value-added products and utilization.
