Abstract—Feed oil samples which are used as mixed feed raw material were taken from six different feed factories in March, May and July. All factories make production in Konya, Turkey and all of the samples were crude soybean oils. Physical and chemical analyses, free radical scavenger effect, and total phenol content were determined on these oil samples. Moisture (M) content was found between ...

This study was conducted to evaluate the effects of bio-oil incorporation on properties of bio-oil-phenol formaldehyde (BPF) resol resins along with the optimization of petro-phenol substitution level. Crude bio-oil prepared from endocarp shells of Ziziphus mauritiana by direct solvolytic liquefaction (ethanol-water 1:1 wt./wt. at 300 °C) was used to partially substitute the petro-phenol (30% t...

Rice bran, a by-product derived from processing rice, is a rich source of bioactive compounds. Recent studies have suggested that the fermentation can improve their biological activities. This study aimed to determined the level of γ-oryzanol, β-glucan and total phenol contents of fermented rice bran from 21 Korean varieties, as well as to evaluate their antioxidant activities. We also assessed...

Abstract Thirty-six resins, each with two replicates, were factorially prepared with three formulation variables: molar ratios of sodium hydroxide to phenol of 0.4, 0.7, and 1.0; levels of resin solids content of 37, 40, and 43 percent; and molar ratios of formaldehyde to phenol of 1.6, 1.9, 2.2, and 2.5. Glue bond quality decreased substantially with a change of NaOH/phenol ratio from 0.4 to 0...

The leaves, barks, flowers, fruits and seeds of Calophyllum inophyllum are widely used in traditional practices. Here in the present study, we aimed to evaluate in vitro antioxidant potential of leaf aqueous and methanolic extracts of C. inophyllum in relation to total phenol and flavonoid contents. DPPH (1,1-diphenyl-2-picrylhydrazyl) free radical scavenging and ferric (Fe) reducing power was ...

A method of phenol determination in plant leaves has been developed which is based on the in situ oxidation of these compounds in an atmosphere containing ammonia, followed by difference spectrophotometry. The development of the phenol pattern has been studied in each separate leaf of a Salvia occidentalis plant grown in short and in long days. During the light period the phenol content (mainly...

Abstract Cacao pod husks ( Theobroma cacao L.) are waste from processing. They contain polyphenolic compounds that obtained by extraction. The most commonly used extraction methods maceration and soxhletation. However, this method has disadvantages such as long time high solvent requirements. This study aimed to compare the soxhletation Microwave-assisted (MAE) on husks. parameters observed wer...
