nut oil was extracted from (black, brown and yellow) cultivars using n-hexane. Physiochemical properties (refractive index, specific gravity, acid value, free fatty acid, peroxide, saponification iodine values of the samples were determined. Storage studies on tiger oils done by monitoring changes in thiobarbituric peroxide moisture content for twelve (12) weeks. The refractive value ranged bet...

conclusions the bleaching procedures using 20% carbamide peroxide and 45% carbamide peroxide and diode laser significantly decreased shear bond strength of brackets to the teeth. 45% carbamide peroxide had a more significant effect on bond strength compared to 20% carbamide peroxide. the difference in bond strength was not significant between laser group and either carbamide peroxide groups. re...

Oxidative stress can be defined as an increase in oxidants and/or a decrease in antioxidant capacity. We aimed to determine total antioxidant capacity (TAC), total peroxide, malondialdehyde and catalase levels in plasma samples, and calculation of oxidative stress index (OSI) in patients with brucellosis to evaluate their oxidative status using a novel automated method. Sixty-nine patients with...

A high reactivity is an essential prerequisite for dissolving pulp. In this study, xylanase modification to increase the reactivity of bamboo dissolving pulp was investigated. The original reactivity of a bamboo dissolving pulp prepared by a prehydrolysis kraft pulping process and bleached by (OP)-H-P (oxygen delignification enhanced with peroxide sodium hypochlorite peroxide) is very low. The ...

Objectives: In preparation for deep frying, the peroxide values and refractive indices of palm, sesame, sunflower oils were measured. The value vegetable used to fry white Indian potato chips in three batches determined after each stage frying. According findings, deep-frying significantly alters index oils. Material & Method: Medical scientific indexing sites like PubMed Google Scholar fin...

The study was conducted to evaluate the physicochemical properties and fatty acids content of lard. qualitative determination using GC-MS analysis revealed that higher concentrations 9- octadecenoic acid methyl ester Hexadecenoic acid, stearate 9,12-Octadecadienoic (Z,Z)- with different concentrations. Many physical chemical lard were determined in including density, viscosity, refractive index...

Objective: To compare the physicochemical properties of four brands vegetable oil sold in Ihiala market.
 Methods: The samples were brought from different super stores market and standard methods used to analyze various samples.
 Results: analysis showed that peroxide value, saponification values, acid ester value glycerol palm kernel (43.91 ± 0.01, 1234.20 74.14 38.56 0.02, 1195.60 0...
