The main goal of the investigation was to measure and estimate thermal stability pinosylvin, pinosylvin monomethyl ether, robinetin, dihydrorobinetin, i.e., characteristic compounds wood Scots pine black locust, respectively. pure were analyzed with chromatography before after they steam-sterilized oven-dried. Detailed thermogravimetric analysis followed check decomposition stilbenes flavonoids...

A two-year field trial with 130 plots was conducted at Tanunda, South Australia. Ten cereal cultivars differing in susceptibility to Pratylenchus thornei, two poor host crops (non-leguminous), and a bare fallow treatment were used to manipulate the numbers of nematodes in the plots in the first year. Initial and final densities were determined for each plot and varied from 0 to 9,400 nematodes/...

Orphanides A., Goulas V., Gekas V. (2013): Effect of drying method on the phenolic content and antioxidant capacity of spearmint. Czech J. Food Sci., 31: 509–513. The changes in total phenolics, hydroxycinammic acid derivatives, and antioxidant properties of spearmint after five drying treatments (convection oven drying, freeze-drying, microwave drying, and air drying with the sun exposure and ...

An accurate assessment of moisture content in feed ingredients is important because moisture influences the nutritional evaluation of feedstuffs. The objective of this study was to evaluate various methods for moisture content determination. In Exp. 1, the weight loss on drying (LOD) of corn, soybean meal (SBM), distillers dried grains with solubles (DDGS), whey permeate, whey powder, spray-dri...
