A feeding trial was conducted to investigate effects of Bacillus licheniformis on growth performance and meat quality broilers. Nine hundred one-d-old broiler chicks were randomly assigned 3 experimental groups with three replicate pens 100 chicks. Three treatments i) control, ii) basal diets supplemented 1 ml B. for each in feed water per day iii) 2 chick day. The supplementation significantly increased body weight grower chickens (p<0.05), improved the conversion 6 0 wk period compared...
ABSTRACT: Soy protein isolates (SPIs) are produced industrially using methods various extraction temperatures and pH values. The effects of process temperature (25°C or 60°C) (8.5, 9.5, 10.5) on isoflavone group B saponin extraction, partitioning, profile during bench‐scale SPI production were evaluated. Protein, isoflavone, increased with increasing pH. Substantial quantities isoflavones saponins remained in the insoluble fraction waste stream. Isoflavones also lost to whey stream, whereas...
A sensitive and selective method has been developed for the simultaneous determination of fluopyram tebuconazole in watermelon soil. The involves an extraction procedure with acetonitrile using high-speed blender, a cleanup by dispersive solid phase (d-SPE) gas chromatography-mass spectrometry (GC-MS). validated soil samples spiked at 0.01, 0.1 0.5 mg/kg. average recoveries were found range 88.2–106% relative standard deviations (RSDs) 1.52–7.65%. limit quantification (LOQ) 0.01 mg/kg was...
A large number of apples produced in China are consumed by people around the world every year. The pesticide residues and apple juice receiving more attention. Herein, 14 frequently used pesticides 3 metabolites were selected as targets to investigate their (120 samples) (40 markets across China, dietary intake risk for consumers was estimated. monitoring results showed 91.7% samples contained detectable residues, six including thiamethoxam, carbendazim, pyraclostrobin, tebuconazole,...
A commercial formulation, 37% dispersible oil suspension (DOS) (fomesafen, clomazone, and clethodim), is being registered in China to control annual or perennial weeds soybean fields. In this paper, a liquid chromatography tandem mass spectrometry method with QuEChERS (quick, easy, cheap, effective, rugged, safe) sample preparation was developed for the simultaneous determination of fomesafen, clethodim, its two metabolites (CSO CSO2) soybean, green straw samples. The mean recoveries our...
Abstract A method using solid-phase extraction for cleanup, followed by high-performance liquid chromatography with ultraviolet detection (HPLC/UV), was developed the determination of forchlorfenuron residues in watermelon. The pesticide is extracted from sample acidic acetonitrile, and extract loaded onto a primary-secondary amine (PSA) column. eluted acetone determined HPLC/UV. PSA column found to provide effective removing greatest number matrix interferences. acetonitrile cleanup...
