ABSTRACT
The food processing sector is a very prominent section of the international market and increased up to approximately $4.5 trillion by 2024 (Businesswire in Global food processing market report, 2019: trends, forecasts, and competitive analysis (2013–2024), 2019 [1]). The increasing demand for healthy fruits and vegetables, organic processed foods, nutraceuticals and functional foods, seafood with packaged food products like ready-to-eat, and frozen processed foods is expected to drive the market growth after pandemic COVID-19 incidence. During processing and handling of horticultural crops, generate large volumes of wastes annually and become a major concern to the whole world. Fruits and vegetables have many bioactive compounds (polyphenols, flavonoids, organic acids, aroma, and flavoring agents, etc.) which have a positive impact on human health because of anti-inflammation, anti-allergic, anti-cancer, anti-atherogenic, and antioxidants properties, depending upon extraction their methods from wastes, efficacy, and bioavailability to the body. Applications of conventional (soxhlet, maceration, percolation, hydro-distillation) and green techniques (solid-phase, supercritical, accelerated solvent, microwave, and ultrasound extractions) for the valorization of horticultural wastes’ conversion in many bioactive components are followed by the potentiality, scalability, and sustainability of the extraction process and highlight the concept of the circular economy as “Waste to Wealth.” © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
ABSTRACT
The corona pandemic 2019 (CoViD-19) has encouraged social movement for the physical distancing and awareness for the use of natural products of medicinal plants for home remedies. Scientists are working to unravel the genetic makeup of corona virus i.e., the causative agent of CoViD-19 in order to find treatments for the infection. Until now, even medicine and vaccine have been formulated in order to help cure the disease. The primary objective of this article is to identify and analyse the published articles in the areas of complementary herbal plant application for antiviral and anti-inflammatory properties, ways to enhanced immunity, and to cure infectious symptoms. One of the paramount options including the use of herb-based medicinal derivatives have been proposed to cure infections with the positive outcome. Most of the established traditional medicinal systems like Traditional Chinese medicine and Ayurveda have recommended a list of several potent herbal and essential oils that ease the symptoms of infections by their regular massaging on the scalp. These results can serve as a yard stick for the efficacious utilisation of food plants as home remedy and for the development of clinical study on disease prevention from natural resources in a global context.
