摘要
对福建省屏南县7个树莓品种果实中的35个营养成分指标进行了比较分析,采用熵权法和模糊综合评价法对树莓果实品质进行了系统性的综合评价。结果表明:树莓果实中含有21种氨基酸,其中包含8种人体必需氨基酸;必需氨基酸/氨基酸总量的变化范围为24.78%~30.90%,平均值为29.02%,必需氨基酸/非必需氨基酸的变化范围为32.95%~44.72%,平均值为40.98%,蛋白质含量水平低于FAO/WHO提出的理想蛋白质标准;呈味氨基酸占氨基酸总量比例的平均值从高到低依次为苦味氨基酸、鲜味氨基酸、甜味氨基酸,药用氨基酸占氨基酸总量比例的平均值为52.25%;在氨基酸评分结果中,亮氨酸的评分值最低,为所有品种的第一限制氨基酸,必需氨基酸的指数范围为49.25~73.28,从高到低品种排序依次为自由>柳林>掌叶覆盆子>仙女>黑钻秋韵>妮丝>黑钻秋炫;在模糊综合评价结果中,综合得分等级“优”的品种为黑钻秋韵,等级“良”的品种包括妮丝、仙女和掌叶覆盆子,等级“中”的品种分别为黑钻秋炫和自由,等级“差”的品种为柳林。综上,树莓果实中的氨基酸种类齐全,具有较高的食用和药用价值,评价结果可为筛选与开发利用闽东山区优良树莓品种提供参考依据。
In the paper,35 nutrients in 7 varieties of raspberry fruits planted in Pingnan County,Fujian Province were compared and analyzed,and the fruit quality was systematically and comprehensively evaluated by entropy weight method and fuzzy comprehensive evaluation method.The results showed that 21 amino acid types,including 8 essential amino acids,were present in the raspberries.The ratio of essential amino acids to total amino acids ranged from 24.78% to 30.90%,with the average of 29.02%,while the ratio of essential amino acids to non-essential amino acids ranged from 32.95% to 44.72%,with the average of 40.98%.Protein content level is below the ideal protein standard of WHO and FAO.The average proportion of flavor amino acids from the highest to the lowest was bitter,umami and sweet amino acids.Additionally,medicinal amino acids accounted for an average of 52.25% of the total.Among the amino acid scores,leucine had the lowest score value and was the first limiting amino acid for all varieties.The essential amino acid index ranged from 49.25 to 73.28.The varieties were ranked from the highest to the lowest as follows:Ziyou,Liulin,RubuschingiiHu,Xiannu,Heizuanqiuyun,Ninsi,and Heizuanqiuxuan.The fuzzy comprehensive evaluation outcomes revealed that the“excellent”rating belonged to Heizuanqiuyun,while Ninsi,Xiannu,and RubuschingiiHu secured“good”grades.Heizuanqiuxuan and Ziyou were awarded“medium”grades,whereas Liulin received a“poor”rating.In summary,raspberry fruits boast a comprehensive amino acid profile and significant edible as well as medicinal value.These evaluation results can provide a theoretical basis for the screening,development and utilization of raspberry products in the mountainous areas of east Fujian Province.
