Abstract
ABSTRACT
The present studies entitled “Development of anardana from unmarketable fruits
of commercial pomegranate” were conducted during 2019-2020 in the department of Food
Science and Technology, Dr Yashwant Singh Parmar University of Horticulture and Forestry,
Nauni, Solan (HP). Pomegranate fruit is rich source of anthocyanins, phenols, crude fibre,
sugars, vitamins, minerals and antioxidants. It has become one of the commercial fruit of HP
in recent years. However, sufficient amount of this crop goes waste because of fruit cracking.
So, the present investigations were conducted to develop anardana from the
cracked/unmarketable fruits of Kandhari Kabuli cultivar of this fruit. The arils after manual
extraction were steam blanched (30 to 90 seconds) and best steam blanching time (60
seconds) was standardized to inactivate enzymes. Treated arils were then dipped in citric
acid solution of varying concentrations for different time periods followed by sulphur
fumigation (0.3% for 60 min) and one best treatment(dipping in 50 % citric acid for 5min)
was selected for drying under various drying modes (mechanical cabinet drier, solar tunnel
drier and open sun). Anardana prepared in the best drying mode i.e, mechanical cabinet drier
was packed in four different packaging material including jute bags, polyethylene pouch
(PEP), aluminium laminated pouches (ALP) and ALP with vacuum and stored under ambient
(18-27oC) and refrigerated (4-7oC) temperature conditions for 6 months. Anardana packed in
ALP with vacuum and stored under refrigerated conditions retained better quality during
storage. However, quality changes were observed faster in ambient as compared to
refrigerated storage conditions. Treated arils can also be dried under solar tunnel drier for the
development of anardana with slightly higher moisture content as compared to mechanical
cabinet drier. The cost of anardana prepared in mechanical cabinet drier was comparable to
the cost of similar product available in the market.
