Chaudhary Charan Singh Haryana Agricultural University, Hisar

Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970. A. L. Fletcher, the first Vice-Chancellor of the university, was instrumental in its initial growth.

    Preparation and storability of garlic powder
    (CCSHAU, 2009) Pardeep Kumar; Garg, M.K.
    The present investigation entitled “Preparation and storability of garlic powder” was carried out with the objectives to study the effect of slicing and flaking of garlic on the drying kinetics and quality. The effect of PEF (Pulsed Electric Field) treatment and the packaging material on the storability of garlic powder were also studied. The fresh garlics were analyzed for proximate analysis. Garlics were then dehydrated and analyzed for drying rate, dehydration ratio, rehydration ratio. Then dehydrated garlics were ground into fine powder and analyzed for bulk density, hunterlab (L*a*b*) values, total sugars and the organoleptic quality. It was found that fresh peeled garlics contained moisture-63.78 percent, protein-5.99 percent, ash-1.91 percent, fat-1.75 percent, crude fiber-1.13 percent and carbohydrates-25.44. Garlic slices and flakes were prepared and different treatment viz., control (without PEF treatment) and PEF (9000V) were given to the samples of garlic. After the pre-treatment, the samples (slices and flakes) were dried in a tray drier at 600C temperature. Then dehydrated garlic were ground into fine powder and packed into LDPE (low density polythene), aluminium foil laminate and glass bottle (amber colour) for storage and were analysed for total sugars, bulk density and organoleptic quality to evaluate the product quality. PEF (9000V) was done for inactivation of micro-organism and enzymes which cause spoilage in the product and increase the shelf-life of the product. PEF treatment resulted in the increase of drying rate and faster removal of the moisture. Three packaging materials were used to pack the garlic powder. There was no significant effect of packaging materials and pre-treatment on the bulk density of garlic powder. L* (lightness) value was good for PEF treated samples and for samples which were packed in aluminium foil laminate and glass bottle (amber colour). The organoleptic score for garlic powder was found good for PEF treated samples and for samples packed in aluminium foil laminate and glass bottle (amber colour).
