Ether extract composition of poultry by-product meal (PBM) varies among feed-grade and pet food-grade sources. Because feed-grade PBM contains a wider variety of processing residues than pet food-grade PBM, it is presumed to be of lower fat quality (i.e., stability). This potential difference in fat quality, or stability, between PBM sources can be accentuated by high environmental temperatures...

The aim of this study was to assess antioxidant properties of four in Lithuanian growing Nepeta varieties, namely N. cataria, N. cataria var. citriodora, N. transcaucasica and N. bulgaricum. The plants were extracted using different polarity solvents, namely acetone, methanol, ethanol and water. The antioxidant properties were assessed by determining total content of phenolics, using free DPPH•...

The life of quench oil is dependant upon its thermal stability. The thermal stability is a function of the quality of the base oil, the antioxidant package used, and the presence of heat and catalysts. In this paper, the mechanism of quench oil degradation and the function of antioxidants will be explained. An example of oxidation testing to determine the role of the base oil and antioxidants i...

Deep-fat frying produces desirable or undesirable flavor compounds and changes the flavor stability and quality of the oil by hydrolysis, oxidation, and polymerization. Tocopherols, essential amino acids, and fatty acids in foods are degraded during deep-fat frying. The reactions in deep-fat frying depend on factors such as replenishment of fresh oil, frying conditions, original quality of fryi...

BACKGROUND Organosulfur compounds usually present a reduced stability especially in the presence of oxygen. This research aimed to study the stability and antioxidant potential of the Allium ursinum watery extract. RESULTS The decrease of the antioxidant capacity verifies an exponential relation which may be formally associated to a kinetically pseudomonomolecular process. The exponential reg...

AIM The antioxidant capacity of human milk reflects the presence and activity of multiple components, which prevent oxidative rancidity. The aim of this study was to use the Oxygen Radical Absorbance Capacity assay to assess human milk antioxidant capacity and find correlations with milk components. METHODS Milk samples collected from 60 breastfeeding women at 1 month postpartum were assayed ...

The aim of this study was to compare the effects of solvent and ultrasound-assisted extraction methods with supercritical fluid extraction on antioxidant activity of loquat (Eriobotrya japonica Lindl.) fruit skin extract in stability of soybean oil at 25°C. Oxidative stability alterations of soybean oils containing 400 (SEA) and 1000 ppm (SEB) of ethanol extract, 400 (SSA) and 1000 ppm (SSB) of...

In this study creams were formulated based on the anti-oxidant potential of herbal extracts and its evaluation. Punica granatum leaves were shade dried and extracted by using soxhlet method with different solvents such as n-hexane, Benzene, alcohol and consistency of different metabolites. In this study creams were formulated based the antioxidant potential of herbal extract and its evaluation....
