Abstract.
The objective of this study was to investigate the effects of low-oxygen storage and 1-methylcyclopropene (1-MCP) on disorders and quality of ‘Empire’ apples. For 2 years, ‘Empire’ apples were obtained from commercial orchards during their harvesting period. After cooling overnight at 3 8C, the apples were treated with or without 1-MCP (1 mL·LL1) for 24 hours and subsequently stored in controlled atmosphere (CA) with 2.5
kPa O2 (+2 kPa CO2) or 1.5 kPa O2 (+1.2 kPa CO2) for 8 months at 1.5 and 3 8C for the first and second year, respectively. In the second year, a third group of the ‘Empire’ apples was also held in respiratory quotient (RQ)-based dynamic CA storage (SafePod) that reached 0.6 kPa O2 (+0.5 kPa CO2), and half of these apples were treated with 1-MCP (1mL·LL1) for 24 hours at 3 8C upon removal after 8 months. All apples were then
evaluated for disorders and quality after 1, 7, or 14 days at room temperature (RT, 23 to 24 8C). Substantial external CO2 injury, flesh browning, and core browning (up to 38% incidence) developed in ‘Empire’ stored in 2.5 and 1.5 kPa O2 during both years of study. Storage in 1.5 kPa O2 reduced flesh browning in the first year and core browning during the second year in apples without 1-MCP, as compared to storage in 2.5 kPa O2. 1-MCPtreated
apples stored in 2.5 or 1.5 kPa O2 had higher overall incidence of disorders than similar fruit without 1-MCP. In contrast, there was negligible incidence (0% to 1%) of these disorders in ‘Empire’ apples held in 0.6 kPa O2, regardless of 1-MCP treatment upon removal. Storage in 0.6 kPa O2 also resulted in the greatest fruit firmness retention while at RT for 14 days. This regime can provide flexibility to postpone 1-MCP treatment
until after storage, to prevent increased susceptibility to disorders during storage, without compromising fruit quality. However, results from the RQ-based dynamic CA with 0.6 kPa O2 were from a single season, and further research is needed to confirm these observations.

超临界流体从葡萄渣中连续提取高附加值分子
受有机废物价值化概念的启发,并朝着可持续经济的方向发展,一种涉及超临界二氧化碳(SC-CO2)和水作为共溶剂的绿色化学提取技术被用于酿酒厂的主要副产品(葡萄渣)。目的是选择性地提取高附加值的分子,特别是酚类化合物和多糖。实验设计涉及应用三种不同的温度条件(40、60和80°C)和400bar的恒压。在SC-CO2提取物中检测到含有低甲氧基(%DE=23)果胶物质的酚类化合物和高分子量分离物(449-478 kDa),用水作为共溶剂

动态控制气调有助于减少梨果采后病害
华盛顿州(WA)提供了美国种植的近100%的有机苹果,占该州苹果产量的20%。虽然西澳中部的半干旱气候允许在生物胁迫影响最小的情况下种植有机水果,但贮藏有机水果是一个挑战,采后病害是首要限制因素。在贮藏5个月后,有机包装商可能会因疾病而损失高达50%的有机水果。目前,没有有效的采后生物杀菌剂可用于采后应用,腐烂是通过采前应用一些有机材料和采后卫生来管理的。动态控制气调(DCA)是有机包装商特别使用的一种新方法,用于延长有机水果的保质期和减少生理紊乱

使用OPTIC-IMS热解吸-离子迁移谱系统对药物氯吡格雷进行清洁验证
清洁验证是药物生产过程中至关重要的一步。它是为了确保在同一设备中不同产品之间切换时不会发生交叉污染。标准的清洁验证程序是基于使用液相色谱(LC)检查清洁度。平均而言,假设验证测试已经通过,在生产过程恢复到下一次运行之前,它需要大约需要30分钟和大量的有机溶剂。 在这项研究中,当使用IMS快速测量技术时,清洗周期可以显著减少。清洁检查使用氯吡格雷作为样本药物进行
