概括

这项对格雷纳什和卡伯内索维尼翁葡萄的研究发现,收获时间和阳光照射并没有显著改变营养含量. 然而,葡萄末的总含量明显高于果汁,抗氧化能力与含量相关.

科学领域:

农业科学农业科学
食品科学食品科学食品科学
植物科学植物科学

背景情况:

格拉纳奇 (GN) 和卡伯内特索维尼翁 (CS) 是适合地中海气候的晚熟红葡萄品种,适应变暖条件.
现有的研究往往侧重于葡萄和葡萄末的最终抗氧化特性,对阳光照射和收获时间对营养特征的影响进行了有限的探索.

研究的目的:

调查阳光照射和收获时间对葡萄汁 (GJ) 和果副产品 (GP) 的营养和抗氧化特性的影响.
探索葡萄制品适用于葡萄酒市场以外的应用的潜力.

主要方法:

来自格雷纳切和卡伯内索维尼翁品种的葡萄汁和葡萄末的成分分析.
评估营养成分,包括蛋白质和全食纤维 (TDF).
测量总含量 (TP) 和总抗氧化能力 (TAC).

主要成果:

由于收获时间或任何葡萄品种的阳光照射,没有观察到营养或抗氧化物质的显著差异.
与格雷纳奇 (GN) 相比,卡伯内索维尼翁 (CS) 的果汁和果汁中的蛋白质含量较高,而格雷纳奇 (GN) 的果汁和果汁中的总食纤维 (TDF) 较高.
葡萄 (GP) 的总含量 (TP) 大约是葡萄汁 (GJ) 的100倍,TP和总抗氧化能力 (TAC) 在所有条件之间都有显著的相关性.

结论:

收获时间和阳光照射并不是这些葡萄品种改变营养和抗氧化剂的主要驱动因素.
葡萄是富含化合物和抗氧化剂的丰富来源,为增值产品提供了潜力.
蛋白质和TDF含量存在显著的品种差异,并且证实了含量和抗氧化能力之间的强烈联系.

Biological Clocks and Seasonal Responses

Biological Clocks and Seasonal Responses

The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.

The Calvin Benson Cycle

The Calvin Benson Cycle

Ribulose 1,5- bisphosphate carboxylase/oxygenase (RuBisCo) is a critical enzyme that catalyzes carbon dioxide assimilation during photosynthesis. However, it is an inefficient enzyme, having an extremely slow catalytic rate. A typical enzyme can process about a thousand molecules per second; however, RuBisCo fixes only around three-carbon dioxides per second. Photosynthetic cells compensate for this slow rate by synthesizing very high amounts of RuBisCo, making it the most abundant single...

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
