Keywords Wheat, Protein Disulfide Isomerase (Pdi), Gene Cloning, Prokaryotic Expression, Protein Purification Abstract In order to further study the key protein that controls the formation of disulfide bonds in wheat proteins, namely protein disulfide isomerase (PDI), the cDNA sequence of the PDI gene of wheat variety “Shaan 253” was cloned using RTPCR method. The gene […]
Keywords Wheat, Alpha-Gliadin Gene, Sequence Analysis Abstract Primers were designed based on the conserved regions at both ends of the alpha-gliadin gene coding region. PCR amplification was performed on the total DNA of the wheat variety “Liangmai No. 2” to obtain a DNA fragment of approximately 900 bp. The DNA fragment was cloned and sequenced […]
Keywords Soy Beverage, Water Slurry, Acidic Peptide, Polypeptide, Enzyme Catalysis, Soy Protein, Taste, Soluble Protein, Digestion, Neutral Protease Abstract ? 2. Soy protein drinks with acidic soluble peptides and polypeptides 1. Protease-catalyzed peptide defatted soybeans use acid protease produced by microorganisms or enzyme preparations containing acidic proteins to denature under acidic conditions (ph 2.5~6.0) and […]
Keywords Rice, High Temperature And Humidity, Storage, Nano Packaging Abstract Purpose: To study the effect of nano-polyethylene packaging bags containing nano-silver, nano-titanium dioxide, nano-attapulgite and nano-silica on the preservation quality of Huaidao No. 5 rice in a high temperature (37 ¡æ) and high humidity (relative humidity 85%) environment. Influence. Method: Huaidao No. 5 rice was […]
Keywords Health Risk Assessment Of Dietary Exposure To Cadmium Rice In Yunnan Province Abstract Objective To assess the health risks caused by the heavy metal cadmium in rice in Yunnan Province. Methods In 2014, 1950 rice samples were collected from all over Yunnan Province. Inductively coupled plasma mass spectrometry (ICP-MS) was used to detect the […]
Keywords Rice, Qinhuangdao City, Pollution Index, Pollution Items, Pollution Situation, Pollution Parameters, Measured Values, Health Standards, Pollution Evaluation, Comprehensive Evaluation Abstract ? Qinhuangdao City is famous for its rice production. Although hygienic appraisals of produced and stored rice have been carried out many times in the past, previous evaluations were limited to quantitative analysis of […]
Keywords Rice, Multi-Source Heterogeneity, Hyperspectral, Information Coupling, Quality Grade Abstract Qualitative and quantitative classification of rice quality grades is achieved by constructing an effective coupling model of multi-source heterogeneous hyperspectral spectral information and image information. First, extract the spectral reflectance feature values of all pixels in the rice hyperspectral interest area and the rice hyperspectral […]
Keywords Spartina, Ecological Invasion, Harm, Control, Spartina Net Abstract Using the community test method, a preliminary screening was developed to develop a chemical that can kill Spartina grass by its roots and is safe for the environment – Spartina net, which can kill Spartina grass by its roots within 60 days. Tests have shown that […]
Keywords Spartina Alterniflora, Spartina Alterniflora, Pros And Cons, Reference Basis Abstract This paper discusses the basic characteristics, uses, positive and negative effects of Spartina grass and Spartina alterniflora, as well as the introduction process in China and the focus of debate. It clarifies the misleading information about Spartina grass and Spartina alterniflora in relevant literature, […]
Keywords Rice Protein, Dextran, Coupling Reaction, Microwave, Functional Properties Abstract Microwave heating was used to study the graft coupling reaction of rice protein-glucan under moist heat conditions, and the process parameters were optimized by measuring the degree of grafting (DG). Within the scope of this experiment, the combination of process conditions to achieve the maximum […]
