Background: Soybean is believed to have good nutraceutical potential which is important for human health. Yellow soybean is generally used for the production of soymilk and other products, while black soybean is less explored. During the production of soymilk, residue, called okara is generated which is reported to have a good amount of nutrient c...
Chapter
The bioremediation process is an eco-friendly process, where the microbes are generally used for the treatment of environmental pollutants. The wastewater contains various types of pollutants including dyes, heavy metals, pharmaceuticals, and personal care products, pesticides, etc. Nature can degrade many of these compounds but in a limited amount...

‘Spring Ecosystem: Definition, Scale and Assessment Protocol’
Book
As most of the natural habitats are presently facing consistently increasing anthropogenic pressures alongside environmental changes on these habitats and their environmental constituents including water, air, soil, biodiversity, etc. Every habitat possesses its unique set of inter-relational physical, biological and social characteristics. Periodi...
Chapter
Nutraceuticals are the food or dietary supplement that can provide health or medical benefits in addition to its basic nutritional value. However, nutraceutical compounds do not provide frequent result, but their regular inclusion in the diet can provide major and long-term health benefits. Global demand for increasing production of important metab...

Presence of pharmaceutical and personal care products (PPCPs) in wastewater and other water sources poses potential health threats and hazards in the ecosystem. Due to the heavy usage of these substances in the fields of agriculture, healthcare, and as personal care products, these pollutants are considered as pseudo-persistent because of their rap...
Article
Full-text available
Proximate and mineral composition, phytochemical content, antinutrient content, and antioxidant activities of Himalayan spices have been analyzed for estimating their nutraceutical potential and compared with other commonly used spices. For understanding the closeness among the spices, factor analysis, and cluster analysis was carried out. The Hima...

Influence of drying temperature (30–50 °C) and relative humidity (RH: 30–80%) on moisture content, energy requirement and quality of Ginkgo biloba leaves with respect to chemical markers namely Ginkgolide A (GA) and Bilobalide (BB), and microbial load of dried materials has been analyzed. Leaves were dried in climate control chamber with varying te...
Chapter
Pharmaceutical and personal care products (PPCPs) are regularly used by human being for their day to day life. These products contains various chemical compounds which are regularly added in our surface and ground water sources either through untreated or partially treated domestic and industrial wastes or through agricultural runoffs etc. These ar...

This paper presents study of thin layer drying kinetics of Picrorhiza kurroa, an important Himalayan medicinal herb based on several drying models and experiments conducted under convection or controlled drying conditions to simulate the thin layer drying processes. Eleven thin layer drying models, namely Diffusion, Jena and Das, Henderson and Pabi...
Article
Influence of drying temperature (30 °C–60 °C) and relative humidity (30%–80%) on moisture diffusivity, energy requirement and quality of Inula racemosa rhizomes, in terms of alantolactone and isoalantolactone, were analyzed. The rhizomes were dried in climate control chamber with constant values of temperature and relative humidity. At low relative...
Article
Bergenia ciliata Sternb., commonly known as Paashaanbhed, is a well known herb of Sikkim Himalaya with various pharmaceutical properties. However, scientific exploration of B. ciliata, growing in the Sikkim Himalaya, for phytochemicals and pharmacological properties is in infancy. With this view, the present study was undertaken to investigate B. c...
