because of the harmful effects of chemicals on human health and environment, the use of these compounds in postharvest technology of horticultural crops is highly restricted. current study was done to evaluate the effect of aloe vera gel on postharvest quality and storage life of fruit cultivar siahe-mashhad. fruit were treated with aloe vera gel of 25 and 33% for 5 min at 22 °c. control fruit ...

Abstract The technology that is commonly used to control postharvest pathogen attacks coating with synthetic chemicals, but this has an unfriendly impact on the environment and consumers. Coating A. vera L gel plant extracts a natural way extend shelf life maintain quality. research was focused finding composition of guava fruit . indica leaf extract provided physicochemical properties optimal ...

The effect of storage time on some properties of groundnut shell briquette with 5, 10, 15 and 20% binder (cassava gel) was studied. The briquettes were prepared using a motorized briquetting machine. The moisture content, durability rating, water penetration, calorific value and the ash content were determined after every 30 days for 6 months. The results reveals that the moisture content of br...

In this study, gelation-facilitated biofilm formation as a new mechanism is proposed for the phenomenon of aerobic granulation in biological wastewater treatment. To obtain an experimental proof for the gelation-based theory, the granulation process was simulated in a chemical system using latex particles for bacterial cells and organic polymers (alginate and peptone) for extracellular polymeri...

Chemically stable porous azacrown ether-crosslinked chitosan films were prepared by reacting varying molar amounts of N,N-diallyl-7,16-diaza-1,4,10,13-tetraoxa-dibenzo-18-crown-6 (molar equivalents ranging from 0, 0.125, 0.167, 0.25 and 0.5) with chitosan. Their chemical and structural properties were characterized by solid state-nuclear magnetic resonance (NMR), elemental, Fourier transform in...

Thyroglobulin secreted in the medium by Fisher rat thyroid line-5 (FRTL-5) cells cultured in the presence of thyroid stimulating hormone (TSH) shows a slower electrophoretic mobility in sodium dodecyl sulfate-polyacrylamide gel electrophoresis and a higher density position in a CsCl gradient than thyroglobulin secreted by FRTL-5 cells cultured in the absence of TSH for 5-7 days. Such a TSH effe...
