This research was designed to test the combined efficacy of hot water dipping (HWD) and leaf extracts of Cistus creticus L. subsp. creticus on the storage quality of fresh Valencia oranges. Experiments were laid down according to a completely randomised design with 10 different treatments. Five replications, with five fruits in each replication, were used in the current study, and research was designed to continue for 150 days. Quality characteristics were observed with 30-days interval. The applications of this study were (1) Control [dipping in water at 25°C for 5 min]; (2) HWD at 50°C for 5 min; (3) HWD + Additives (A) [Arabic gum (0.2%), potassium sorbate (0.05%), citric acid (0.05%) and vitamin C (0.05%)] at 50°C for 5 min; (4) Additives alone at 25°C for 5 min; (5) 1.0% C. creticus leaf + HWD + A; (6) 1.0% C. creticus leaf + A; (7) 0.5% C. creticus leaf + HWD + A; (8) 0.5% C. creticus leaf + A; (9) 0.5% C. creticus leaf + HWD and (10) 0.5% C. creticus leaf. According to the results obtained, both the HWD and C. creticus, alone or in combination, were effective in preserving orange weight during storage, preventing pathogenic decay, maintaining visual quality and fruit firmness, delaying the reduction in titratable acidity, increasing ascorbic acid content and reducing respiration rate of the orange fruits. Results also suggested that the combined effect of HWD with C. creticus leaf extracts provided the highest efficacy.

热水浸泡和Cistus creticus L.叶提取物对新鲜巴伦西亚橙的贮藏品质的综合影响

这项研究旨在测试热水浸泡（HWD）和Cistus creticus L. subsp叶片提取物的综合功效。creticus对新鲜巴伦西亚橘子的贮藏品质。实验是根据完全随机的设计进行的，其中包含10种不同的治疗方法。本研究使用了五次重复，每个重复中有五个结果，并且研究计划持续150天。每隔30天观察一次质量特征。这项研究的应用是（1）对照[在25°C的水中浸泡5分钟]；（2）在50°C下HWD 5分钟; （3）HWD +添加剂（A）[阿拉伯胶（0.2％），山梨酸钾（0.05％），柠檬酸（0.05％）和维生素C（0.05％）]在50°C下放置5分钟；（4）添加剂在25°C下单独放置5分钟；（5）1.0％C. creticus叶子+ HWD + A; （6）1.0％的景天叶+ A; （7）0.5％的景天叶+ HWD + A; （8）0.5％的景天叶+ A; （9）0.5％的C. creticus叶+ HWD和（10）0.5％的C. creticus叶。根据获得的结果，HWD和C. creticus单独或组合使用均可有效地保存储存期间的橘子重量，防止病原体腐烂，保持视觉品质和水果硬度，延迟可滴定酸度的降低，增加抗坏血酸的含量并降低了橙色水果的呼吸速率。结果还表明HWD与C. creticus的联合作用 叶提取物提供最高的功效。
