Good results for mango postharvest with an edible coating of carboxymethyl cellulose

Mangoes (Mangifera indica L.) are known for attractive appearance, aroma and flavor, with high nutritional value (Ribeiro and Schieber, 2010). However, they are climacteric, highly perishable fruits whose postharvest life is limited (C?rdenas-Coronel et al., 2012). One of the main problems faced by the mango industry is its postharvest management that, coupled with the short shelf life of the fruit, restricts its transport in distant markets. The use of low temperature storage is one of the most effective ways to maintain the quality of mango post-harvest, and extend its shelf life (Alvarez et al., 2020). However, mango fruits are extremely sensitive to cold injury at temperatures below 13 ?C (Zhang et al., 2017). Several techniques have been used to reduce postharvest losses, one of them is the use of edible coatings (Singh and Singh, 2012), which can be applied directly to the product, and is one of the main practices to preserve the quality of fresh fruits (Valencia-Chamorro et al., 2010; Dhall, R. K., 2013), moreover, they have the additional advantage of reducing the use of non-biodegradable packaging (Hassan, et al., 2018). Carboxymethyl cellulose (CMC) is a cellulose derivative, widely studied as an edible coating (Arnon et al., 2014), has great potential to form a transparent and flexible layer and adhere to the surface of the treated product (Ali et al., 2021). CMC is tasteless, odorless, non-toxic, biodegradable, as well as having low cost and being soluble in cold and hot water (Dehsheikh & Dinani, 2019).? The findingsIn the present research, theimpact of a 3% carboxymethylcellulose (CMC) coating was studied on mangoes during storageat 20? C for 10 days. Results showed that treatment with 3% CMC delayed fruit maturation,suppressed the increase in total soluble solids, decreased firmness, and showed substantiallyhigher titratable acidity, along with maintenance of skin color, in contrast to uncoated fruits. In?conclusion, 3% CMC coating can be an effective approach for maintaining fruit quality of harvested mangoes during storage at 20?C.
