摘要
为了筛选适合四川丘陵地区生产高品质桑椹的果桑品种,对新育成的果桑品种团桑9号、团桑16号、芙椹1号以及现行果桑品种大10和中桑5801号的桑椹主要营养成分进行测定分析。检测结果表明,团桑9号桑椹的总酸质量分数最高,达0.82%;花青素、总糖、还原糖、维生素C的质量比分别为1.99、65.52、62.42、0.103 7 mg/g;可溶性固形物的质量分数为11.03%。5个果桑品种的桑椹中均含有包括8种人体必需氨基酸在内的17种氨基酸,其中团桑9号的氨基酸总量比大10高24%,苏氨酸、谷氨酸、甘氨酸、胱氨酸、缬氨酸、蛋氨酸、亮氨酸、异亮氨酸、酪氨酸、组氨酸、精氨酸、支链氨基酸含量居5个检测品种之首,鲜味氨基酸和药效氨基酸含量仅次于中桑5801号。综合检测结果,果桑新品种团桑9号桑椹中的营养成分及氨基酸含量丰富,适合作为四川丘陵地区生产优质桑果的专用果桑品种。
In order to screen mulberry varieties for fruit production with high quality of mulberry fruit suitable for planting in hilly region of Sichuan Province, we determined and analyzed main nutritional compositions in fruits of the newly bred fruit mulberry varieties Tuansang 9, Tuansang 16, Fushen 1, and the current fruit mulberry varieties Da 10 and Zhongsang 5801. The results showed that total acid content in fruits of Tuansang 9 was the highest, reaching 0.82%. The mass ratio of anthocyanin, total sugar, reducing sugar and vitamin C in fruits of Tuansang 9 was 1.99, 65.52, 62.42 and 0. 103 7 mg/g respectively. The mass fraction of soluble solids in fruits of Tuansang 9 was 11.03%. Mulberry fruits of these 5 fruit mulberry varieties all have 17 amino acids including 8 essential amino acids for human health. Among them, the total content of amino acid in fruits of Tuansang 9 was 24% higher than that of Da 10. The contents of threonine, glutamic acid, glycine, cystine, valine, methionine, leucine, isoleucine, tyrosine, histidine, arginine acid, and branched-chain amino acids was the highest in fruits of Tuansang 9, and the contents of amino acids with flavor enhancement effect and amino acids with medicinal function in fruits of Tuansang 9 were slightly lower than those in Zhongsang 5801. Based on these results, the new fruit mulberry variety Tuansang 9 has rich content in nutritional composition and amino acid of fruit, and can be used as one of special mulberry varieties suitable for producing high quality of mulberry fruits in hilly region of Sichuan Province.
