Replacement of sugar in the product formulation of “Bomboyson” by jaggery
“Bomboyson” is a traditional heat desiccated dairy product of eastern Nepal, prepared using khoa, sugar, and ghee, and has a great commercial potential. This study was carried out to standardize the product and study its nutritive value and storage life for the organized production. The formulation was based on survey and the best product was selected using 9-point hedonic rating scale method. The sugar in the best product was replaced by jaggery, and both were compared with the most popular market product for sensory and nutritional qualities. The products were stored at ambient (25°C) and refrigerated (5°C) temperatures to study the microbiological qualities. Bomboyson prepared from 100 parts khoa, 40 parts sugar, and 20 parts ghee was found to be superior (P < 0.05) in terms of overall sensory attributes. The proximate composition of sugar-added bomboyson was found to be 8.98 ± 0.04% moisture, 28.66 ± 1.16% fat, 16.42 ± 0.56% protein, 1.08 ± 0.12% total ash, 44.86 ± 0.86% carbohydrate, and 91.02 ± 0.04% total solids. The proximate composition of control and sugar-added product were same (P > 0.05) while both the product had lower contents (P < 0.05) of moisture and total ash than the jaggery-added product. The microbiological study confirmed that the products were acceptable throughout the storage period of 28 days at 5°C and 21 days at 25°C.
Review on Recent Advances in Value Addition of Jaggery based Products
Jaggery is sugarcane based natural sweetener made by the concentration of sugarcane juice without any use of chemicals. It is available in the form of solid blocks and in semi-liquid form. Besides this, the sap collected from some palm trees such as palmyra-palm (Borassus flabellifer L.), coconut-palm (Cocos nucifera L.), wild date-palm (Phoenix sylvestris Roxb.) and sagopalm (Caryota urens L.) is used for preparation of jaggery. It contains the natural sources of minerals and vitamins inherently present in sugarcane juice and it is one of the most wholesome and healthy sugars in the world. The micro nutrients present in the jaggery possess antitoxic and anti-carcinogenic properties. In India, of the 300 Mt of sugarcane produced, 53% is processed into white sugar, 36% into jaggery and khandsari, 3% for chewing as cane juice and 8% as seed cane. The methods of converting sugarcane and manufacturing sugar, gur and khandsari are different but a great value is added in the manufacturing of these consumable final products. Further it offers employment opportunity to millions of people. Of the total world production, more than 70% of the jaggery is produced in India but most of the jaggery business suffers from losses. The development of different value added products from jaggery and their commercial availability becomes needs of the hour to sustain future profitability in the jaggery trade.
CONTINUOUS PRODUCTION OF BLUE‐TYPE CHEESE FLAVOR BY SUBMERGED FERMENTATION OF Penicillium roqueforti
A two-stage continuous process for the production of Blue cheese flavor from lipolyzed milk fat by submerged fermentation of Penicillium roqueforti was developed. In the first stage, P. roqueforti was grown aerobically on a corn-steep liquor/sucrose medium at 25° C, pH 7, aeration rate 1 liter air/min/L medium, and dilution rate 0.05 hr−1. The effluent air and culture over-flow were led to a maturing tank and allowed to age 24 hr. The mycelial culture was then pumped into a second fermentor to which lipolyzed milk fat was also fed continuously. An average 24 hr contact time between mold mycelium and fatty acids was maintained. The fatty acids and perhaps other components of the lipolyzed cream were metabolized by the P. roqueforti mycelium to produce a fluid product with a Blue cheese-type flavor. Small portions of this product were acceptably added to snack and party dips and salad dressings, as a Blue cheese replacement.
