摘要

以贵州主栽蓝莓巴尔德温、灿烂、粉蓝和圆蓝为试材，以单果重分别分为大、中、小3个级别，对比分析外观、理化性质、营养成分及抗氧化活性、制汁特性及挥发性物质的差异。结果显示，果实大小对不同品种及各项指标的影响各不相同，4个蓝莓品种的出汁率随果实的变小而降低，果实大小对果型指数、含水量、糖、TSS、果汁色泽等指标的影响不大，中等果实总酚含量则显著低于大果和小果；圆蓝果汁的挥发性物质比其他3个品种的均高，果实大小对其有一定影响，但无明显的变化规律。由此可知，对于交叉种植的蓝莓果园，应严格按品种采收，避免不同品种混合一起的品质不均匀。

Abstract

In order to understand the effect of the size on the quality characteristics of blueberry, blueberries were divided into large, medium, and small based on the weight. The comparison of physical-chemical properties, nutritional composition, antioxidant activity, juice produce ability and volatile compounds were analyzed. The results indicated that the effects of fruit size on varieties and indexes were different, the juice yield were decreased with the fruit size decreasing for all four cultivars. However, fruit size has little effect on fruit index, water content, sugar, TSS, and fruit juice color. The total phenol content of medium fruit was significantly lower than that of large fruit and small fruit. The volatile compounds of juice of Gardenblue is higher than the other three cultivars, and the fruit size has some influence on it without an obvious pattern. It can be seen, for cross-planting blueberry orchard, blueberry picking should be separated by the size to avoid different varieties.
