The effect of pre-treatments, packaging and storage conditions on fruit quality of peach (Prunus persica L Batsch) cv. Flordasun *Ritu Thakur1, Dilip Singh Kachwaya2 and Jasmine3 12Department of Agriculture, Mata Gujri College, Sri Fatehgarh Sahib, Punjab 3Department of Agriculture, G.K.S.M. Government College, Tanda Urmar, Hoshiarpur, Punjab ABSTRACT A study was carried out in entitled “The effect of pre-treatments, packaging and storage conditions on fruit quality of peach (Prunus persica L Batsch) cv. Flordasun” at the Agricultural laboratory of Mata Gujri College, Shri Fatehgarh Sahib, Punjab (India) and Krishna Cold Storage Sirhind, Punjab (India) during the year 2016. The experiment was laid out in Completely Randomized Design (CRD) with five replications. At 6% concentration, pre treatment of calcium chloride (CaCl2) and hot water (550C) treatment was given for 10 minutes and 1 minutes respectively. Further the treated fruits were packed in three packaging films viz. high density polyethylene (HDPE), low density polyethylene (LDPE) and cling film. Then packed fruits were stored under cold storage (0-10C) and room temperature (30-350C). Fruits samples were analysed for various chemical characteristics after 5 days of interval of storage (0, 5, 10, 15, 20).  Among all the treatments, T2 (CaCl2 + LDPE + Cold storage) treatment was found better than others in respect of characters viz. total soluble solids, titratable acidity, ascorbic acid and pH qualities. Moreover, T9 (Hot water + Cling + Cold storage) exhibited maximum mean value for total sugars. Treatment T13 showed minimum values of all the parameters studied. After analysing the present results it was concluded that treatment of T2 (CaCl2 + LDPE + Cold storage) might be suggested as effective and economical treatment for improving the quality of peach fruits.
