Objective: The present study was carried out to compare the quality of new and 24 months old sample of Chyawanprash from the same brand. Material and Methods: Total polyphenolics, total reducing sugar, ascorbic acid, hydroxymethyl furfural (HMF), and fibre content were measured in both the new and 24 months old sample of Chyawanprash. Results: Results obtained reveal the reduction in the percen...
The influence of saccharides on the formation of acrylamide (AcA) was investigated. The reducing saccharides reacted with asaparagine to form AcA, but the non-reducing saccharides, except sucrose, gave no AcA. AcA formation from a mixture containing glucose and asaparagaine was suppressed by the non-reducing saccharides, especially trehalose (76% suppression) and neotrehalose (75% suppression)....
BACKGROUND The active ingredients and thus pharmacological efficacy of traditional Chinese medicine (TCM) at different degrees of parching process vary greatly. OBJECTIVE Near-infrared spectroscopy (NIR) was used to develop a new method for rapid online analysis of TCM parching process, using two kinds of chemical indicators (5-(hydroxymethyl) furfural [5-HMF] content and 420 nm absorbance) a...
We have constructed and applied an algorithm to simulate the behavior of zeolite frameworks during liquid adsorption. We applied this approach to compute the adsorption isotherms of furfural-water and hydroxymethyl furfural (HMF)-water mixtures adsorbing in silicalite zeolite at 300 K for comparison with experimental data. We modeled these adsorption processes under two different statistical me...
Renewable and low-cost lignocellulosic wastes have attractive applications in bioethanol production. The yeast Saccharomyces cerevisiae is the most widely used ethanol-producing microbe; however, its fermentation temperature (30-35°C) is not optimum (40-50°C) for enzymatic hydrolysis in the simultaneous saccharification and fermentation (SSF) process. In this study, we successfully performed an...
Pairing the electrocatalytic hydrogenation (ECH) reaction with different anodic reactions holds great promise for producing value-added chemicals driven by renewable energy sources. Replacing sluggish water oxidation a bio-based upgrading can reduce overall cost and allows simultaneous generation of high-value products at both electrodes. Herein, we developed membrane-electrode assembly (MEA)-b...
The aim of this study was to ascertain the anti-arthritic active fraction of Capparis spinosa L. (Capparidaceae) fruits and its chemical constituents. The adjuvant arthritic rat model was developed to evaluate the anti-arthritic effects of different fractions of ethanol extraction from C. spinosa L. The fraction eluted by ethanol-water (50:50, v/v) had the most significant anti-arthritic activi...
