The olive fruits are rich source of oil, vitamins, minerals, organic acids and pigments. contain high level bioactive compounds. aim this study was to examine the effect heat treatment on tocopherols, total phenolics antioxidant activity in green black olives, as well their fatty acid composition. instrumental methods used experiment were performance liquid chromatography (HPLC), gas with flame...

Microalgae strains, newly isolated from freshwater in mangrove areas of Central and North Coasts Sao Paulo State (Brazil), were evaluated regarding total protein lipid content, fatty acids profile. The biochemical composition was compared with that observed strains obtained by UTEX Culture Collection (USA). Among seven identified green algae, Monoraphidium contortum (CCMA-UFSCar-701) presented ...

The objective of this study was to relate farm feeding practices in different production systems to milk fatty acid (FA) composition on the scale of round tankers. Milks from 10 collection rounds in the French department of the Haute-Loire (10 to 36 herds per collection round) were sampled twice and three times during winter and grazing periods, respectively. The collection rounds were principa...

A modelagem molecular foi empregada para avaliar o processo de adsorção teórico durante a mistura dos aditivos e formação ligações cruzadas em composições borracha natural (NR). ideia acompanhar as mudanças ocasionadas quando óleos vegetais, simulados pelos seus componentes majoritários, substituem ácido esteárico (C18) como ativador. Os resultados teóricos corroboram os dados experimentais est...

The objective of this work is to characterize and determine the fatty acid composition Pellonula leonensis oil from Congo River Nianga Lake, in order bioavailability docosahexaenoic (DHA) eicosapentaenoic (EPA) acids. fish were caught southern Congo–Brazzaville localities Kombé (Brazzaville) Boko (Pool department) Lake (Pointe-Noire). extracted by Soxhlet method using hexane as so...

Following an agronomic approach for the Ca enrichment of Rocha pears, this study aimed to assess interactions between mineral nutrients in fruit tissues at harvest and after storage 5 months characterize implications on profile sugars fatty acids (FA). A total seven foliar sprays (with concentrations 0.1–0.6 kg·ha−1 Ca(NO3)2 0.8–8 CaCl2) were applied pear trees. After harvest, fruits stored mon...

An accurate, sensitive and selective method is developed for determination of ergocalciferol (vitamin D2) in human plasma using LC-MS/MS. After liquid-liquid extraction with n-hexane, ergocalciferol was derivatized by reacting with 4-phenyl-1,2,4-triazoline-3,5-dione (PTAD), a strong dienophile based on Diels-Alder reaction. Ergocalciferol and its deuterated internal standard, ergocalciferol-d6...
