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.

    TECHNOLOGY FOR PRODUCTION OF SUPERIOR QUALITY CINNAMON BARK POWDER AND ESSENTIAL OIL USING CRYOGENIC GRINDING AND SUPER CRITICAL FLUID EXTRACTION
    (College of Food Processing Technology and Bio-Energy, Anand Agricultural University, Anand, 2018) Monika R. Bhoi; Dr. R. F. Sutar
    Cinnamomum zeylanicum is an evergreen tropical tree, the inner bark of the tree of Cinnamomumverum (Cinnamomum Zeylanicum) and it is belonging to the “Lauraceae” family. Cinnamon Bark is one of the well-known, oldest and most flavor filled spices. Cinnamon Bark is considered a remedy for respiratory, digestive and gynecological ailments and also as ayurvedic medicine. It’s essential oils and various extracts from cinnamon bark have been shown to possess various antibacterial, antioxidants, anti-diabetic, anti-cancerous and anti-inflammation activities. Cryogenic grinding is method of powdering products at sub-zero temperature ranges from 0 to -194⁰C. In Cryogenic technology, the liquid nitrogen provides the refrigeration needed to pre-cool the spices and maintain the desired low temperature by absorbing the heat generated during the grinding operation. Super critical fluid extraction (SFE) has emerged as a highly promising environmentally benign technology for selectively recovering thermally labile bioactive ingredients from natural sources. The nutraceutical produced by SFE using carbon dioxide (CO2) at near-ambient temperatures are preferred by consumers due to their superior quality and higher bioactivity without the problems of residual solvent and microbial contamination. The present investigation was undertaken to optimize cryogenic grinding parameters to obtain superior quality of cinnamon bark powder and for extraction of essential oil by supercritical fluid extraction technology. Cinnamon is long stick with mean length, width and thickness of 61 mm, 12.59 mm, and 2.65 mm respectively. Cinnamon bark contained moisture content5.1±0.02%, carbohydrate content by difference 52±0.37%, protein content 3.5±0.0092%, total fat 4±0.35%, crude fiber content 33.±0.07%, ash content 2.4±0.05% and volatile oil content 3.5±0.041%.The effect of grinding temperature ( 0, -20, -40 ,-60, -80 and -100⁰C), feed rate (8, 9 and 10kg/hr) and sieve size (0.8, 1.0 and 1.5mm) were evaluated with respect to grinding time, volatile oil content, particle size, energy consumption, and liquid nitrogen consumption. The optimization of cryogenic grinding of cinnamon bark was carried out using three factorial Completely Randomized Design. Optimized condition for cryogenic grinding of cinnamon bark powder was -80⁰C temperature, 0.8mm sieve size, 10 kg/hr feed rate. Volatile oil extracted at optimized cryogenic grinding condition had volatile oil yield of 3.01%.
