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.
