Essay / A Perspective on Supercritical Extraction and Herbal Extracts...
Supercritical Extraction and Herbal Extracts: A PerspectiveThe world is moving toward “alternative,” “complementary,” “holistic,” and “integrative” medical systems ". Growing interest in personal care, particularly in Europe and North America, has led to a rise in many "herbal products". Changing trends have led people to turn to products of natural origin rather than synthetic origin. Products of natural origin are considered part of a healthy lifestyle. These herbal products contain phytochemical extracts as a major component. These extracts, although used for centuries and believed to be safe, must be standardized and tested according to modern science. This is necessary because now these extracts are used by a wider population for disease prevention and not for management of acute symptoms. Modern medicinal practices require that these plant extracts be standardized and their safety validated according to standards. However, preparing standardized extracts is not an easy task. These snippets have a sequence of many small but significant steps that need to be considered. Traditional practices focused on understanding the growing conditions, harvest cycle, and details of herb extraction. This often led to low returns. However, when it comes to manufacturing on an industrial scale to meet market demand, the entire procedures (GMP) must be strictly defined and followed, and new extraction methods must also be adopted to better performance. Standardization of the preparation of these plant extracts will guarantee their quality to the consumer. Global Scenario The global market for these plant extracts is estimated at more than $60 billion. India's current share in these exports is estimated to be about......half of paper processing. The by-products of these food processing units can be used to extract antioxidants. SCE is used to extract β-carotene and lycopene from by-products of the tomato industry. SCE process optimization can result in up to 50% yields of lycopene and β-carotene from tomato by-products. In the same spirit, tocopherols can be extracted from olives and phenolic compounds from grape seeds. This will open new avenues for extraction of essential plant extracts at economical cost by food processing units and better sustainability. In conclusion, the manufacturing and supply of herbal extracts will be a growing sector in the coming years. The industry is moving towards extraction processes that are environmentally safe, simple and offer high yield. Supercritical extraction is up to the task and will lead the way into the future.
