Use of Protein Content, Amylose Content, and RVA Parameters to Evaluate the Taste Quality of Rice.

Taste quality of rice is the key to its value. However, it is greatly affected by rice types and the environment. It is a complex but necessary factor to accurately evaluate the taste quality of various types of rice in different environments.

Comprehensive Evaluation of 17 Qualities of 84 Types of Rice Based on Principal Component Analysis.

Rice quality is a complex indicator, and people are paying more and more attention to the quality of rice. Therefore, we used seven rice varieties for twelve nitrogen fertilizer treatments and obtained eighty-four rice types with seventeen qualities. It was found that 17 quality traits had different coefficients of variation.

Multi-marker scans coupled to high-resolution mass spectrometry strategy for global profiling combined with structure recognition of unknown trace chlorogenic acids in Lonicera Flos.

Deep investigation, profiling of chemical diversity of constituent compounds and discovery of novel structures is a great challenge. A novel comprehensive and effective approach to mine trace unknown compounds combined with structure recognition in complex matrix is developed, in order to profiling potential Chlorogenic acids (CGAs) in Lonicera Flos (LFs): using multiple neutral loss/precursor ion (NL/PI) markers scans combined with high resolution mass spectrometry (HRMS). The workflow included (i) Fragmentation rules deduced by Q-orbitrap and selection of multiple NL/PI markers.

Toxicogenomic evaluation of liver responses induced by acrylamide and glycidamide in male mouse liver.

In current studies, histopathologic method, Agilent GeneChip hybridization and Western blot were used to investigate the toxicity of acrylamide (AA) and glycidamide (GA) in male mouse livers. The histopathologic results demonstrated that AA and GA could cause oxidative damage to mouse liver. Middle dose of GA and AA (50 mg/kg b.

Protective effect of allicin against glycidamide-induced toxicity in male and female mice.

Acrylamide is known to be a neurotoxic, genotoxic, and carcinogenic compound. Glycidamide has a close relationship to the toxic mechanism of acrylamide. In order to explore the toxic mechanism of acrylamide, we further discussed the effects of oral administration of allicin on glycidamide-induced toxicity by determining the hematological parameters like AST, ALT, LDH, BUN, creatinine, ROS, and 8-OHdG, and biochemical parameters such as MDA, MPO, SOD, GST and GSH in the kidney, liver, brain and lung of male and female mice for the first time.

Protective effects of apigenin against furan-induced toxicity in mice.

Furan, a food contaminant formed by heating, is possibly carcinogenic to humans. In this study, we discussed the effect of administration of apigenin on furan-induced toxicity by determining the ROS content, oxidative damage, cytokine levels, DNA damage, and the liver and kidney damage in a mouse model. Our data showed that apigenin administered at 5, 10, and 20 mg kg(-1) bw per day could decrease the toxicity induced by furan to different extents.

Detection of furan levels in select Chinese foods by solid phase microextraction-gas chromatography/mass spectrometry method and dietary exposure estimation of furan in the Chinese population.

In this study, a solid phase microextraction-gas chromatography/mass spectrometry (SPMEGC/MS) method was developed to detection the levels of furan in 191 selected food products obtained from the Chinese markets. The performance of the analysis method was evaluated by some quality parameters such as limit of detection (LOD), limit of quantification (LOQ), linearity, recovery, and runto-run (n=6) and day-to-day (n=18) precisions. The LOD and the LOQ of the method were 0.

Potential protective effects of oral administration of allicin on acrylamide-induced toxicity in male mice.

Acrylamide (AA) forms during the heating of starchy foods at high temperature, and is regarded as a potential genotoxic carcinogen. However, with the worldwide concern about the carcinogenicity of AA, how to reduce the toxicity of AA has become a hot research topic. In this study, we further discussed the effects of oral administration of allicin on AA-induced toxicity by determining the hematological, biochemical and immunological parameters in the serum, kidney, liver, and brain of male mice.
