Science and Technology of Aroma, Flavor, and Fragrance in Rice

With contributions from a broad range of leading researchers, this book focuses on advances and innovations in rice aroma, flavor, and fragrance research. Science and Technology of Aroma, Flavor, and Fragrance in Rice is specially designed to present an abundance of recent research, advances, and innovations in this growing field.

Aroma is one of the diagnostic aspects of rice quality that can determine acceptance or rejection of rice before it is tested. Aroma is also considered as an important property of rice that indicates its preferable high quality and price in the market. An assessment of known data reveals that more than 450 chemical compounds have been documented in various aromatic and non-aromatic rice cultivars. The primary goal of research is to identify the compounds responsible for the characteristic rice aroma. Many attempts have been made to search for the key compounds contributing to rice aroma, but any single compound or group of compounds could not reported that are fully responsible.

There is no single analytical technique that can be used for investigation of volatile aroma compounds in rice samples although there are currently many technologies available for the extraction of rice volatile aroma compounds. These technologies have been modified from time to time according to need, and many of them are helping the emergence of a new form, particularly in the distillation, extraction, and quantification concept.

This new volume helps to fill a void in the research by focusing solely on aroma, flavor, and fragrance of rice, helping to meet an important need in rice research and production.

Key features of this volume:

• provides an overview of aromatic rice from different countries

• looks at traditional extraction methods for chemicals associated with rice aroma, flavor, and fragrance

• presents new and modern approaches in extraction of rice aroma chemicals

• explores genetic engineering for fragrance in rice

Deepak Kumar Verma is an agricultural science professional and is currently a PhD Research Scholar in the specialization of food processing engineering in the Agricultural and Food Engineering Department, Indian Institute of Technology, Kharagpur (WB), India. In 2012, he received a DST-INSPIRE Fellowship for PhD study by the Department of Science & Technology (DST), Ministry of Science and Technology, Government of India. Mr. Verma is currently working on the research project "Isolation and Characterization of Aroma Volatile and Flavoring Compounds from Aromatic and Non-Aromatic Rice Cultivars of India." His previous research work included "Physico-Chemical and Cooking Characteristics of Azad Basmati (CSAR 839-3): A Newly Evolved Variety of Basmati Rice (Oryza sativa L.)". He earned his BSc degree in agricultural science from the Faculty of Agriculture at Gorakhpur University, Gorakhpur, and his MSc (Agriculture) in Agricultural Biochemistry in 2011. He also received an award from the Department of Agricultural Biochemistry, Chandra Shekhar Azad University of Agricultural and Technology, Kanpur, India. Apart of his area of specialization in plant biochemistry, he has also built a sound background in plant physiology, microbiology, plant pathology, genetics and plant breeding, plant biotechnology and genetic engineering, seed science and technology, food science and technology etc. In addition, he is member of different professional bodies, and his activities and accomplishments include conferences, seminar, workshop, training, and also the publication of research articles, books, and book chapters.
