The effects of enzyme-assisted cold-pressing (EACP) on the physicochemical attributes of Cannabis sativa (hemp) seed oil were investigated using five enzyme preparations: Protex 7L, Viscozyme L, Kemzyme, Feedzyme, and Natuzyme. The oil contents (28.4–32.8%) offered by the enzyme-treated hempseeds were found to be significantly (p ,0.05) higher than that determined for the control (26.7%). The p...

statement of problem: due to the growing popularity of vital bleaching by carbamide peroxide it is imperative to understand the effect of such agents on enamel and dentine. purpose: the purpose of this study was to evaluate the effect of a 16% carbamide peroxide bleaching gel; vivastyle on enamel staining susceptibility. materials and methods: thirty bovine specimens were selected and randomly ...

This study was conducted to assess the effects of 0.5% Preservative Mixture (PM) containing calcium lactate (40%), sodium diacetate (40%) and sodium chloride (20%) on the microbiological, chemical and sensory quality of chicken meat nuggets stored at 4±2 C and under Modified Atmosphere Packaging o (MAP). There were two experimental groups of samples, namely control and PM-treated. The results s...

OBJECTIVES This study evaluated the effectiveness of different home bleaching agents on color alteration and their influence on surface and subsurface microhardness of discolored bovine enamel. MATERIAL AND METHODS Forty-five fragments of bovine incisors were randomly allocated into 3 groups (n=15) according to the bleaching agent: 10% carbamide peroxide gel (CP10), 16% carbamide peroxide gel...

The purpose of this study was to compare two in-office bleaching methods with respect to tooth color change and level of hydrogen peroxide penetration into the pulp cavity and to evaluate relationships between penetration level and color change. Eighty extracted canines were exposed to two different bleaching regimens (conventional vs sealed bleaching technique). After exposure to 38% hydrogen ...

to develop a new more accurate spectrophotometric method for detecting monoamine oxidase inhibitors from plant extracts, a series of amine substrates were selected and their ability to be oxidized by monoamine oxidase was evaluated by the hplc method and a new substrate was used to develop a peroxidase-linked spectrophotometric assay. 4-(trifluoromethyl) benzylamine (11) was proved to be an exc...

the aim of this study was to determine the effects of 40% hydrogen peroxide and 15% carbamide peroxide on microhardness and color change of a silorane-based composite resin in comparison with two methacrylate-based composites.fifty-four disc-shaped specimens (a3 shade) were fabricated of filtek p90 (p90), filtek z350xt enamel (z350) and filtek z250 (z250) (3mespe) (n=18). the samples of each co...

background: oxidation of lipids causes reduction of different properties of products that contains lipids. nowadays, there is a growing demand for the natural antioxidants due to the harmful effects of synthetic antioxidants such as bha, bht and tbhq. objective: in this study, extract of aerial parts of echinacea purpurea l. was used instead of synthetic antioxidants in cake then, antioxidant a...

Background: Many common cancers, such as prostate, breast, and colon, are caused by harmful substances and compounds contained in processed foods, including nitrite-treated meats. The aim of this study was to investigate the possibility of replacing sodium nitrite with Monascus purpureus pigment in sausage and to assess its antimicrobial, antioxidant, color, and sensory properties. Methods: The...
