The present invention relates to a simple, economical, and efficient cyclic process for producing rhombic dodecahedron shaped glycine enriched, free flowing common salt from brine, said process comprising steps of adding glycine of concentration ranging between 10 to 25% to the saturated bnne, evaporating the saturated brine containing glycine to obtain crystals having high content of glycine, with mother liquor, washing the crystals with saturated brine to obtain rhombic dodecahedron shaped glycine enriched common salt having glycine content ranging between 0.5 to 1.0% and a washed brine, combining the mother liquor and the washed brine to obtain resulting brine, subjecting the resultant brine to solar evaporation, and repeating the steps of (iii) to (v) to obtain rhombic dodecahedron shaped glycine enriched common salt from brine with glycine concentration ranging between 0.5 to 1.0%.

The present invention relates to a simple, direct and cost-effective process for the preparation of agarose of high gel strength and low gelling temperature from naturally occurring or cultivated Gracilaria spp. more particularly Gracilaria dura, said process comprising steps of pre-treating the dry seaweed with alkali, rinsing the pre-treated seaweed until the washing shows a pH ranging between 7 and 8, adding water, autoclaving to obtain extractive, treating the extractive with charcoal and Celite to obtain hot extractive, vacuum-filtering the hot extractive over a Celite bed, freezing the filtrate into a mass and thawing the mass, redissolving the mass in water by heating in an autoclave, repeating the freeze-thaw cycle, straining the product to remove thawed liquid and thereafter squeezing to expel residual liquid to the extent possible to obtain agarose, and an agarose thereof.

The present invention relates to novel extracts of Salicornia species. The present invention particularly relates to novel extracts of Salicornia species which show anti-tubercular activity. The present invention also relates to a process for the preparation of novel extracts of Salicornia species with anti-tubercular activity and also to the use thereof for the treatment of tuberculosis.
摘要:
The present invention relates to enhancement of anti-tubercular activity of active fraction isolated from Salicornia brachiata. The invention also discloses the non-toxic nature of the fraction and positively identifies Sucrose as its main constituent. Pure Sucrose is shown to have no anti-tubercular activity indicating thereby that activity of the fraction resides in one or more of the minor constituents. The minor constituents are shown to be relatively low molecular weight entities and a chromatographic technique is disclosed for separating them from the bulk sucrose to probe their activities and structures in detail, as also the possibility of their synthesis if the leads thrown up are novel.

The present invention relates to use of inexpensive semi-refined kappa carrageenan as a seaweed polysaccharide in preparation of tough, biodegradable films exhibiting improved performance over films obtained from refined kappa carrageenan. The formulation requires no gelling salt and the only other essential components of the film are glycerol and water, the former being used as plasticizer as reported in the prior art. The films can be recycled and reprocessed if required. The performance of the films can be further enhanced by incorporating polyvinyl alcohol that lends toughness and clarity as also natural rubber latex that imparts greater elasticity and barrier properties. Films of optimum composition can be pulse heat sealed immediately after casting and used for preparation of soft capsules and pouches. It is possible to store solvents and oils in the pouches. In view of the more eco-friendly processing of semi-refined kappa carrageenan compared to refined kappa carrageenan, films made with the former would also effectively be “greener”.

The present invention provides a process for photocatalytically treating stains of chilly and turmeric caused on kitchen tiles and platforms by coating a thin film of photocatalyst made of a semiconductor such as titanium dioxide uniformly dispersed in dilute silica sol thereon and using a light source such as a fluorescent lamp to irradiate and photoexcite the photo catalytic thin film by the small amount of UV radiation included in the fluorescent light, resulting in photo decomposition and auto-cleaning of the stains.
摘要:
A method for preparation of iodizing agent for the use in the formulation of iodised salt that offers excellent stability of iodine in iodised salt is developed and the unrefined salt iodised with this compound was tested for its stability in presence of moisture, temperature and metal salts at higher temperature. The hydrotalcite type layered compound was used to prepare such compound and part of carbonate was substituted with iodate anion. The iodising agent exhibited excellent stability of iodine in iodised salt.
