Abstract

Kinnow is a well-known mandarin grown in Haryana. Edible coatings are useful for controlling ripening by reducing the oxygen penetration into the fruits, thus, reducing metabolic activity and softening of fruits. Present study was carried out during 2019 and 2020 at Horticulture Farm, CCS Haryana Agricultural University, Hisar, Haryana. Kinnow fruits were treated with different bio-extract coatings, viz. Aloe vera extract, til oil, CMC, lac coating, lemongrass oil and commercial coating. The carotene content of the fruits did not differ significantly irrespective of the coatings. Decay loss and activities of pectin methyl esterase and cellulase were minimum resulting in better retention of the firmness in Aloe vera extract coated fruits. Minimum polygalacturonase activity was noticed in commercial coating treated fruits.
