1. Determination of carrageenan in jellies with new methylene blue dye using spectrophotometry, smartphone-based colorimetry and spectrophotometric titration
Abstract Carrageenan is a seaweed polysaccharide widely used as a food gelling and thickening agent. The New Methylene Blue dye was tested as an analytical reagent for the quantification of carrageenan in commercial jelly samples. The main spectral peaks of the dye decrease with increasing carrageenan-to-dye molar ratio up to 1. Three analytical procedures w

2. Optimization of hot-air drying conditions on functional properties of flour from dried South African sweet potato cultivars (Impilo and Bophelo) using the response surface methodology
Abstract The response surface method (RSM) has an important application in formulation of new products. This study determined the effect of electric hot-air drying on the functional properties of flour made from orange-fleshed sweet potato (OFSP). Flour from the cultivars Bophelo (B) and Impilo (IM) were treated with 13 temperature-time combinations designed

3. Gelation of commercial pea protein isolate: effect of microbial transglutaminase and thermal processing
Abstract In the studied commercial pea protein isolate (PPI) some physicochemical modifications are induced in the protein structure during its processing. That fact would result into a reduction of proteins techno-functional properties. It has been evidenced by Differential Scanning Calorimetry the protein denaturation what gives as a result poor gelling ab

4. SOLUÇÕES A BASE DE ÁLCOOL PARA HIGIENIZAÇÃO DAS MÃOS E SUPERFÍCIES NA PREVENÇÃO DA COVID-19: COMPÊNDIO INFORMATIVO SOB O PONTO DE VISTA DA QUÍMICA ENVOLVIDA
The recent coronavirus pandemic has already victimized hundreds of thousands of people around the world, and until this moment does not exist any medicine for healing or vaccine to avoid the contamination. Therefore, the actions of social isolation associated with the use of masks and surface and hand sanitation are the most effective actions to avoid the vi

6. Encapsulation of flaxseed oil extract in alginate-salep system by ionic gelation
The objective of the current study was to encapsulate flaxseed oil extracted from finely grounded flaxseed powder and determined for its fatty acids content by GC/FID. Ionotropic gelation method was used to form beads containing 40% flaxseed oil with vitamin E being used as an antioxidant agent. The study employed calcium chloride solution as crosslinking ag

7. Development and in vitro/in vivo evaluation of thermo-sensitive in situ gelling systems for ocular allergy
Ocular allergy is one of the most common disorders of the eye surface. Following diagnosis this condition is typically treated with preparations containing antihistamines. However, anatomy of the eye and its natural protective mechanisms create challenges for ocular drug delivery. Rapid elimination of antihistamine substances due to short residency times fol

8. Effect of hydroxyurea (HU) on gelatinization mechanism of type I collagen suspensions
ABSTRACT Mutant hemoglobins thermodynamic phase transitions (HbS, HbC, etc.) have been the causes of serious hemoglobinopathies that have been affecting mankind since the dawn of human race. HbS polymerization is the best known of these transitions and the original cause of sickle cell anemia. Hydroxyurea (HU, NH2CONHOH) is widely used as the main drug admin

9. Exopolysaccharide production from Bacillus velezensis KY471306 using statistical experimental design
Abstract Exopolysaccharide (EPS) biopolymers produced by microorganisms play a crucial role in the environment such as health and bio-nanotechnology sectors, gelling agents in food and cosmetic industries in addition to bio-flocculants in the environmental sector as they are degradable, nontoxic. This study focuses on the improvement of EPS production throug

10. Influence of different cosmetic vehicles in mechanical and physical properties of hair treated with oxidative hair dyes
ABSTRACT Hair care products play a significant role in the cosmetic market and aim at improving hair brightness, breakage resistance, and color change. In this study, we analyzed the possibility of the formulation of oxidative dyes in different vehicles impacting the hair’s both mechanical and physical properties. Light brown and light blond dyes were prep

11. Effect of setting on the gelling properties of a protein concentrate from giant squid ( Dosidicus gigas) mantle
Abstract Different studies on obtaining protein concentrates or surimi from giant squid ( Dosidicus gigas) have reported that soft gels are obtained in comparison with other fish species. Therefore, the aim of this research was to investigate the effect of the setting (30 and 60 °C, for 0, 30, 60, and 90 min) on the gelling capacity as a possible alternati

12. Formulation and evaluation of topical herbal gel for the treatment of arthritis in animal model
ABSTRACT The objective of the study is to formulate and evaluate a topical herbal gel containing Cardiospermum halicacabum and Vitex negundo leaf extracts for their anti-arthritic activity in rats. Twelve herbal gel formulations were prepared using 1.5% of gelling agents carbopol 934 (F1-F6) and carbopol 940 (F6-F12) and they were evaluated for physical appe
