Litchi fruits (cv. Purvi) were harvested at fully mature stage
(90–100% of the pericarp showing red colour) from the orchard
of Horticulture Garden, Department of Horticulture (Fruit and
Fruit Technology), Bihar Agricultural University, Sabour, Bhagalpur,
Bihar. Fruits of uniform size, shape, colour and free from disease,
pest or physical injury were selected for the experiment. A total 300
fruits were taken for the experiment and divided into 6 lots having
50 fruits in each treatment. After that, fruits were treated with
aqueous solutions of SA (0.5 mM, 1.0 mM) and chitosan (2%) alone
or in combination while in control,fruits were treated with distilled
water. Treatments of fruit were performed by dipping them in 10 L
treatment solution containing Tween-20 (2 g L−1) as surfactant, at
25 ◦C for 5 min. After treatment application, fruits were air-dried
and stored at 4 ± 1 ◦C for 6 days. At 2 days interval, fifteen fruits
from each treatment(each replicate contained five fruit) were sampled
at random and analysed for various physico-chemical quality
attributes on fresh weight basis.
