Through a greenhouse simulation control experiment, the effects of alternating salty and light irrigation treatments on the morphological traits, clonal growth, biomass accumulation and distribution pattern of the exotic clonal plant Spartina anglica were studied. There are 6 types of irrigation treatments in the experiment: single fresh water irrigation (d), single salt water irrigation (x), […]

The effects of enzymatic hydrolysis on the structure and rheological properties of glutinous rice, japonica rice and indica rice starch were studied by treating glutinous rice, japonica rice and indica rice starch with pullulanase. The results showed that after pullulanase treatment, the crystallinity of the three rice starches decreased and the amorphous area increased; the […]

Objective To establish a simple reflux-assisted digestion atomic fluorescence method for the determination of heavy metals arsenic and mercury in rice. Methods A simple reflux-assisted wet digestion method was used to digest the samples, and a dual-channel atomic fluorescence photometer was used to determine the As and Hg heavy metal contents in rice. Results Under […]

total of 70 rice samples were randomly collected from some markets in typical rice-producing areas such as Jiangxi, Hunan, Anhui and Guangdong in southern my country and from farmers in polluted areas. The contents of Cd, Zn and Se in the samples were measured respectively, and the content differences and differences in rice from different […]

In order to screen for stable and reliable Liuhe rice origin confirmation elements, two canonical correspondence analyzes were conducted to study the environmental factors that affect the distribution of rice sampling points in Liuhe, Jilin Province, and to analyze the influence relationship and stability of the rice origin confirmation elements on a regional scale. The […]

In order to improve the quality of food products based on rice starch and inhibit its retrogradation, the effects of carrageenan, gum arabic and pectin on the gelatinization, rheology and retrogradation properties of rice starch were systematically studied. The addition of carrageenan and pectin significantly increased the peak and trough viscosity of rice starch; all […]

In order to observe the effect of transgenic Cry1Ac/Sck rice on the immune function of mice, BALB/c mice were divided into 4 groups according to body weight, namely transgenic rice group, non-transgenic rice control group, AIN93G feed normal control group and positive control group. The mice were fed corresponding diets for 30 days, and the […]

Rice is one of the staple food raw materials in my country. During the storage process, quality deterioration phenomena such as increased hardness, decreased viscosity, and dehydration are prone to occur, which restricts the development of rice staple food. The main component of rice, starch, is easy to retrograde, which causes the storage process of […]

In order to protect the brand benefits of Wuchang rice, Fourier transform near infrared spectroscopy (FTNIS) combined with chemometric analysis was used to conduct origin identification research on a total of 191 rice samples from Wuchang and non-Wuchang areas. , the results show that: the identification analysis model established by using the factorization method combined […]

Lysine (Lys), aspartic acid (Asp) and alanine (Ala) represent the three types of positively charged, negatively charged and uncharged amino acids respectively. A rapid viscometer and flow analyzer are used. A rheometer was used to study the effects of amino acids on the gelatinization and rheological properties of rice starch. The results showed that both […]
