Exopolysaccharides have various applications due to their unique rheological properties as in food, pharmaceutical and other industries. Exopolysaccharides also have some medical applications as anti-cancer, anti-viral and immune-modulator. In present study, 72 bacterial strains were isolated from root nodules of eight different leguminous plants and screened for exopolysaccharide production. Out of 72 isolates, 15 bacterial isolates showing good growth and exopolysaccharide production in primar

Multi Wall Carbon Nano Tubes (MWCNTs) have enormous potential in biomedical researches. Structural and size-dependent properties such as length, diameter have notable effects on cytotoxicity which represent major challenge in this field. The aim of this research is evaluation of peroxidase mimic activity of MWCNTs as Nanozyme via Hydroquinone-H2O2 coupled colorimetric system cell viability which was tested on HU02 Human Fibroblast cells using different concentrations of MWCNTs by MTT assay. Resu

Food spoilage occurs due to the microbial and enzymatic activities which alter the composition of the product with their metabolites. Paneer, also called Indian cottage cheese, gets spoiled due to poor quality of milk, faulty production methods, unhygienic processing conditions, and poor refrigeration facilities. The spoilage has been detected conventionally by destructive sampling methods. This paper proposes a non-destructive method of detecting paneer spoilage using a Radio-Frequency (RF) bas

This work aimed to extract betalain pigments from red beet (Beta vulgaris L.) by different extraction methods: water and citric acid (2%) solvents to select the optimal method for extraction. In addition, the study determined total betalains, and effect of pH, time and temperature on betalains stability. The results showed that, pH, temperature and time of extraction did not have effect on the stability of Vulgaxanthin-1 pigment extracted using water and citric acid solvents. The concentration o

Background: Moringa oleifera leaves (M.O.L.) have medical and nutritional properties, which make these leaves appropriate for using to make various food products such as juices. Fruits and vegetables commonly consumed as a beverage and juice. Mostly, to have higher quality juice with fresh taste, the standard is often fresh juice not-processed, however, their shelf life is less than 6 or 7 days depends on the fruit and vegetable types. Thus, they have been preserved by several methods such as th

Different thermodynamic parameters of solvation were evaluated for the benzoic acid, orthotoluic acid, paratoluic acid, 2-chloro benzoic acid and 4-chloro benzoic acid by measuring the molal solubilities of their saturated solutions at different temperatures in binary mixtures of ethanol-water solvents. The solubility was increased when the mole fraction of ethanol increased in the binary mixtures, and also their solvation behaviors were increased by increasing temperature. The experimental solu

There are several methods to prevent oxidation of oils, one of which is the addition of synthetic antioxidants. However, due to the fact that synthetic antioxidants have undesirable effects, such as the effect of mutagenicity and carcinogenicity in human body, it is necessary to investigate the sources of natural antioxidants in order to replace synthetic compounds. In this study, methanolic extract of Anacyclus pyrethrum root were extracted. Extracted extract were added to sunflower oil at diff
