Abstract
The objective of this study was to evaluate the impact of harvesting stages (turning-color fruit and light red color) and postharvest treatments (distilled water, hot water at 35 °C, 10% Aloe vera, 2% CaCl2, 5% Mint, and 5% Catnip) for 5 min on the quality and storability of tomato fruits cv. Sangaw stored at 10 ± 1 °C and a relative humidity of 90%–95% for 20 days. Fruit harvested at the turning-color fruit stage presented significantly lower weight loss, greater firmness, and higher amounts of vitamin C, total phenol, and calcium (3.22%, 1118.31 g mm/s, 15.83 mg 100 g−1, 95.49 mg 100 mL−1 FW, and 0.14%, respectively). However, the tomatoes harvested from the light red color fruit stage presented the highest contents of total soluble sugars, total sugars, and lycopene (4.36%, 3.99%, and 41.49 mg kg−1, respectively). Notably, the postharvest treatment of tomato fruits with 2% CaCl2 significantly decreased weight loss and resulted in greater firmness, pH, total sugar, total phenol, and calcium contents (3.90%, 1212.39 g mm/s, 4.83, 3.85%, 95.60 mg 100 mL−1 FW, and 0.18%, respectively) than the control. Hence, coating with 10% Aloe vera resulted in the highest amount of total soluble solids and the highest amount of vitamin C. Tomato picked at the turning-color fruit stage and immersed in 5% Mint significantly lowered the loss of fruit weight, increased the total titratable acidity, and had the lowest content of lycopene. Additionally, the fruits harvested at the same stage and immersed in 2% CaCl2 retained greater firmness, total phenol content, and calcium content. On the other hand, fruits harvested in the light red stage and dipped in 5% Mint presented the highest total soluble sugars and total sugar contents. Finally, the harvested tomato fruits coated with 10% Aloe vera retained a relatively high level of vitamin C, indicating the storage life and quality of the tomato fruits.

期刊介绍:
Coatings is an international, peer-reviewed open access journal of coatings and surface engineering. It publishes reviews, research articles, communications and technical notes. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. Full experimental and/or methodical details must be provided. There are, in addition, unique features of this journal:
* manuscripts regarding research proposals and research ideas will be particularly welcomed
* electronic files or software regarding the full details of the calculation and experimental procedure - if unable to be published in a normal way - can be deposited as supplementary material
