Anand Agricultural University, Anand

Anand Agricultural University (AAU) was established in 2004 at Anand with the support of the Government of Gujarat, Act No.(Guj 5 of 2004) dated April 29, 2004. Caved out of the erstwhile Gujarat Agricultural University (GAU), the dream institution of Sardar Vallabhbhai Patel and Dr. K. M. Munshi, the AAU was set up to provide support to the farming community in three facets namely education, research and extension activities in Agriculture, Horticulture Engineering, product Processing and Home Science. At present there seven Colleges, seventeen Research Centers and six Extension Education Institute working in nine districts of Gujarat namely Ahmedabad, Anand, Dahod, Kheda, Panchmahal, Vadodara, Mahisagar, Botad and Chhotaudepur AAU's activities have expanded to span newer commodity sectors such as soil health card, bio-diesel, medicinal plants apart from the mandatory ones like rice, maize, tobacco, vegetable crops, fruit crops, forage crops, animal breeding, nutrition and dairy products etc. the core of AAU's operating philosophy however, continues to create the partnership between the rural people and committed academic as the basic for sustainable rural development. In pursuing its various programmes AAU's overall mission is to promote sustainable growth and economic independence in rural society. AAU aims to do this through education, research and extension education. Thus, AAU works towards the empowerment of the farmers.

    REDUCTION IN THE LEVEL OF AIR-BORNE CONTAMINATION BY THE USE OF AIR WASHING AND UV RAYS AND ITS EFFECT ON SHELF-LIFE OF PANEER
    (AAU, Anand, 2000) Goel, Bhawtosh Kumar; Shah, U. S.
    Clean and sanitized air to minimize the air-borne contamination during processing and packaging of dairy and food product is an essential requirement to improve the microbial quality and shelf-life of the products. Providing relatively clean and sanitized air a sufficiently large workspace is very expensive and sometirne practically uneconomical also. Keeping these aspects in view the present work was undertaken to evaluate the performance of air washing system with and without enclosure and UV sanitization treatment. The system performance was tested at the diflFerent time of the day, seasons and locations with and without addition of sanitizers in the wash water. The information on distribution of microbial load in the air with respect to the time of the day and night period, seasons and locations is also generated for effective application of air sanitization system. Paneer is one of the important Indian dairy product having good market potentiality. The short shelf-life of paneer is the major bottleneck for commercial production. The effect of the clean and sanitized air and hygienic practices on shelflife of paneer stored at 22±1°C and 7±2°C is investigated to confirm the effectiveness of the system. In the absence of any disturbances, the microbial load in the air shows a definite pattern of distribution. It is minimum at the afternoon (13:30) and mid night (02:00) hours and maximum in the evening stagnation period, while moderate in the morning (08:00) hours. The higher counts are present in the air during the dry period such as winter, summer and those days of rainy season when rainfall has not occurred. The light rainfall causes immediate reduction in the microbial load in the atmosphere but quickly regains to its original load. The disturbances such as sweeping of floor, opening and closing of shut1;ers lead to heavy contamination. Locations having open area with dusty land and approach roads have higher microbial load as compared to the locations surrounded by building structures and having pakka roads. The performance of the treatments was evaluated by analysing the data using graphical representation, regression analysis, mathematical model and statistical analysis having two factors Randomized Block Design. The reduction efficiency of air washing treatment showed a correlation with initial population of TVC (R2 = 0.78) and YMC (R2 = 0.75). The rate of reduction of microorganisms that is linear in log scale, is highly correlated with the initial population. The enclosure showed effectiveness to control the microorganisms inside the cabin as the microbial population in the surrounding increases. The log of reduction rate showed good correlation with the log of initial total population of microorganisms falling on the floor during air washing and UV treatment with a R2 value of 0.9747 for TVC and 0.8952 for YMC, respectively. When air washing treatment was analysed using the mathematical model developed by Shah(1993), it was observed that the operating points of air washing were covered by a trend line that is better than the upper boundary of the operating points of GAU LAFU without mirror and without enclosure effect. The combined air washing treatment with enclosure effect and UV was covered by the same boundary line when GAU LAFU was operated with mirror and enclosure effect, The addition of lysol, potassium permanganate and benzaUconium chloride each at a concentration of 200 ppm in the water did not significantly (P<0.05) improve the effectiveness of the air washing over clean water. The air washing system operated in the upstream of the wind direction as enclosure effect in another room was at par with the above treatments. The UV treatment showed inconsistent effect in the country side room due to break down of the enclosure effect being an open area with high wind velocity in the surroundings. To confirm the effect of air borne contamination on the shelf life ofpaneer graphical, regression and statistical (Split Plot Design) method was employed. The air borne contamination significantly (P<0.05) affects the shelf life ofpaneer. The LAFU and combined effect of air washing, enclosure and UV sanitization treatment were at par while outside exposed paneer showed significantly lower shelf life. The untreated air showed a shelf life of about one day and six days at 22±1°C and 7±2°C, respectively while treated air showed a shelf-life of 2 days and 12 days at corresponding storage temperatures, respectively. "While, the market sample of paneer showed the shelf-life of less than a day and less than 3 days at corresponding storage temperatures, respectively. The above confirmation is showing a very good scope of the method for its industrial application in food, pharmaceutical and such other industries.
