Abstract

Tea is one of the most popular and inexpensive beverages of the world. India is the largest producer of black tea and the largest consumer of this beverage. Tea crop in India is infested by various insect and mite species that cause substantial damage to this foliage-crop. The use of pesticides has often been considered as the only way to manage pest infestation on tea. Indiscriminate application of pesticides poses various risks to environment, human health and also the plant itself in the long run. There is a need to relook into the usage pattern of synthetic pesticides on this crop and development of non-chemical-based strategies for pest management.

Abstract

The present study surveys the current techniques of oil extraction, specifically mechanical pressing, and ultrasound-assisted extraction methods. Based on research studies, we review each approach in terms of advan­tages and disadvantages, which are especially highlighted in relation to their impact on yield, quality, affordability, and scalability. In addition, a new appro­ach to Mahua oil extraction is introduced here, which would improve process efficiency and output while paying attention to environmental and economic factors. The current review again emphasizes the need to use the latest technologies, mechanical pressing, and ultrasound-assisted extraction to meet the emerging requirements of health-conscious and environment-friendly practices in essential oil production.

Keywords
