Abstract
ABSTRACT The present study entitled “Development of novel products form osmo-dried apples” was conducted in the Department of Food Science and Technology, Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh during the year 2016-2017. Apple is very popular in human diet due to its high nutritional value but owning to its perishable nature losses, occurs during its handling. To minimize the losses, drying is the better option which causes the reduction in water activity of food products and osmotic dehydration enhances the quality of dried products. In the present study osmo-dried apple pops and rings were developed from ‘Golden delicious’ apple and further utilized for the development of novel products viz. apple choco shots and apple pie. The technology for osmo-dried apple pops with diameter of 28 mm and apple rings with thickness of 0.5 cm, dipping in 70oB osmotic syrup sugar for three hours and honey for four hours at 50oC was optimized, with drying time of eight hours for sugar osmo-dried apple pops and seven hours for honey osmo-dried apple pops. In case of apple rings, drying time of five hours for sugar osmodried apple rings and four hours for honey osmo-dried rings was optimized. The products were packed in PET and glass jars and stored at room temperature. The quality in terms of nutritional and sensory was evaluated at fresh as well as during storage at an interval of three months. Minimum changes were found during storage in apple pops and rings. Honey osmo-dried apple pops and rings were found better in quality in terms of sensory and quality characteristics and having less water activity. For enhancing the flavor, cinnamon concentration of 1.5 per cent and 1.0 per cent for osmodried apple pops and rings was optimized respectively. Novel products were prepared from osmodried apple pops and rings i.e. apple choco shots and apple pie. Energy value of apple choco shots and apple pie from honey-cinnamon osmo-dried pops and rings were 231.22 Kcal/100g and 261.81 Kcal/100g respectively. These products were rated better by the panel of judges through nine point hedonic scale. From the storage study, it was found that apple choco shots packed in laminated films can be stored upto 45 days with minimum changes while apple pie wrapped in cling wrap and packed in cartons have to consume fresh. Thus, the developed technology can be commercially explored at industry level for the production of quality osmo-dried apple pops and apple rings and their value added products like apple choco shots and apple pie. The technology will be efficient and profitable to growers for the utilization of this fruit and ensuring better returns. These dehydrated fruits can be commercialized as an important component of diet.
