A pre-storage heat treatment of 38°C for four days applied to apples (Malus domestica cv. ‘Granny Smith’) before standard storage in air at 0°C was found to inhibit the development of superficial scald. Apples stored for three months after heat treatment had superficial scald levels similar to those of apples dipped in diphenylamine (DPA), while all control apples had scald. This inhibitory effect was no longer apparent after five months of storage. The heat treatment inhibited the accumulation of α-farnesene and conjugated trienes in apple cuticle while DPA inhibited only a-farnesene oxidation. Heat treated apples also had lower polyphenoloxidase activity in the peel than untreated apples. This treatment may be a substitute for chemical treatments for short-term storage of scald- susceptible apple varieties. 相似文献

贮前复合热处理对果蔬品质和病虫害的影响 总被引：4，自引：1，他引：3
贮前热处理是一种无毒无残留的物理处理方法,可在贮藏期间延缓某些果蔬衰老,控制病害的发生,提高贮藏质量。热处理与其它处理相结合可增强热处理的效果、降低热处理强度、弥补其不足,成为现在热处理领域的研究热点。复合热处理主要包括热处理与生物拮抗、物理处理、化学处理相结合的综合处理方式。生物拮抗菌中对酵母菌的研究较深入,取得较好效果。热处理与其它物理或化学方法的有机结合,可以进一步提高保鲜效果。综合处理的先后顺序和处理参数的选择对处理效果起决定性作用。综述了近年来国内外的研究成果,以期为此领域的研究提供帮助。 相似文献

Sunburn on apples in the Western Cape region of South Africa can result in yield losses of up to 50%. Application of kaolin-based particle film (Surround® WP) increases leaf and fruit surface reflectivity, thus potentially reducing heat load and sunburn. Trials were performed during 2002/2003 and 2003/2004 to assess the effectiveness of kaolin particle film in controlling sunburn on ‘Granny Smith’, ‘Braeburn’, ‘Fuji’, ‘Royal Gala’ and ‘Cripps’ Pink’ apples. Fruit quality and ripening were monitored following 1–4 months in regular atmosphere cold storage at −0.5 °C. Sunburn on exposed fruit was significantly reduced in ‘Granny Smith’ and ‘Fuji’. Kaolin treatment improved fruit colour of ‘Granny Smith’ and ‘Royal Gala’, and delayed starch conversion in ‘Granny Smith’ at harvest and during the early storage period but not thereafter. Incidence of watercore at harvest was significantly reduced by kaolin treatment, but this disorder disappeared during cold storage in both treatments. There were no effects on skin anthocyanin or phenolic concentrations in any cultivar compared to unsprayed fruit. 相似文献

Several fungicide treatment schemes were assayed on ‘Golden Delicious’ and ‘Jonagold’ apples. The free sugars (fructose, glucose, sorbitol, sucrose and their total) of freshly harvested apples were measured and compared to those obtained with the corresponding untreated apples (control). With ‘Golden Delicious’, the fungicide treatments generally increased the content of fructose, sucrose and total sugars, but had no effect on the glucose content. With ‘Jonagold’, similar effects were observed, but their intensities generally were lower than in ‘Golden Delicious’; in some cases, the treatments even decreased the sugar content. 相似文献

以海南3个主栽杧果品种,5种类型果实为试材,研究了3种不同的热水处理方式对主要采后病害的控制效果及其对果皮伤害和贮藏期的影响。结果表明,51℃、15min热水处理对供试果实炭疽病和蒂腐病2种病害的控制效果最好;供试果实对热的敏感性存在差异;热水处理加速果实的后熟速度,但适宜的热水处理可大大提高好果率,且病害发生严重时,因能有效控制病害发生从而延长贮藏时间。综合分析后推荐小贵妃、大贵妃、大台农、小金煌使用51℃、15min热水处理为最适宜的热处理方式。小台农使用47℃、20min热水处理作为最适宜热处理方式。 相似文献

采后热空气处理对嘎拉苹果质地的影响及其作用机理 总被引：4，自引：1，他引：3
应用整果穿刺(Puncture)和质地多面分析(TPA)的方法研究采后热处理(38℃4d)对嘎拉苹果质地的影响,同时研究热处理对果实不同溶解性果胶含量的影响,建立不同溶解性果胶含量与果肉硬度之间的相关性。研究发现,2种测试方法都能较好的反映苹果质地特点;嘎拉苹果的果肉硬度与水溶性果胶含量呈极显著的负相关,与碳酸钠溶性果胶呈极显著的正相关,而与CDTA(环乙二胺四乙酸)溶性果胶、硫酸溶性果胶、总果胶含量没有显著的相关性。采后热处理能显著提高贮藏后期嘎拉苹果的果皮和果肉硬度、果肉的凝聚性、咀嚼性和回复性,这主要是由于热处理显著减少了嘎拉苹果水溶性果胶含量的上升,并维持较高的碳酸钠溶性果胶,但对CDTA溶性果胶、硫酸溶性果胶和总果胶没有显著的影响。 相似文献

采后热空气处理对金冠苹果后熟衰老及病害的影响 总被引：2，自引：1，他引：2
金冠苹果采用38℃,72h或96h热空气处理,可降低0℃贮藏中果实的呼吸强度和乙烯释放量,延缓非溶性果胶的降解,维持较高的硬度、脆度,同时也会加速果皮的褪绿变黄和固酸比的上升,尤其是38℃96h处理的作用效果更为明显,显著提高了货架期后(20℃7d)苹果的质地品质和可接受程度,延缓衰老。苹果分别接种扩展青霉、灰葡萄孢霉,0℃和20℃条件下其病害发生率和腐烂均很严重,采用38℃96h热空气处理可以完全控制病害的发生,避免腐烂。可见,热空气处理一方面能延缓金冠苹果的后熟衰老,另一方面还能控制贮期病害的发生。 相似文献
