| dc.description.abstract | The present studies were conducted at Fruit Research Station, Jallowal-Lesriwal, Jalandhar, Department of Fruit Science and Department of Biochemistry, Punjab Agricultural University, Ludhiana during the year 2019-20 on three mandarin varieties viz. Kinnow, W Murcott and Daisy. The physico-chemical parameters like fruit size, weight, juice content, moisture content, TSS, TSS/acid ratio, carotenoids and sugars were recorded maximum at final stage of harvesting whereas titratable acidity presented a declining array from first to final stage of fruit harvesting. Seed size of fruit increased while peel thickness decreased with fruit development but no particular trend was observed for specific gravity of fruit. Color of fruit juice, peel and pulp improved with fruit maturity. Vitamin C and total flavonoid content varied from 24.23 to 42.11 mg/100ml and 2.08 to 7.57 mg (RE) g-1 respectively, and found highest in mid-sampling stages. Peel of mandarins consisted of greater antioxidant activity, total phenolic content and total flavonoid content as compared to pulp of fruits. In peel and pulp, antioxidant activity declined during fruit development. Pectin was increased substantially with relation to fruit maturity, however, limonin was registered highest at mid stage of sampling. Irrespective of stages, peel and seeds were the rich source of pectin and limonin, respectively. Kinnow was found highly suitable variety for table purpose utilisation as it contained higher antioxidants along with different internal quality attributes such as TSS, sugars etc. However, fruits of W Murcott and Daisy were also good source of different types of antioxidants at young and mid stage of fruit development, respectively. During this study, leaves of mandarin varieties contained higher concentration of nutrients than the peel and pulp. Different nutrients exhibited a specific pattern during fruit growth and development. | en_US |
