Cold atmospheric plasma-induced alterations in the multiscale structural and functional properties of guar gum.

The use of guar gum in the food industry faces challenges owing to its large molecular weight and high viscosity. Cold atmospheric plasma (CAP) is a novel technique that utilizes the reactive species produced by high voltage discharge to modify food ingredients. In this study, guar gum was treated with CAP at different powers and duration, and its rheological properties, molecular structure, thermal stability, emulsifying activity, and stability were evaluated.

Microwaving plus enzymatic pretreatment of safflower seeds increases the phenolic content and oxidative stability of extracted oil.

In this paper, microwave-assisted (MW-AE), enzyme-assisted (Ene-AE) and microwaving plus enzymatic treatment (MW + Ene-AE) were used to explored their effects on the polyphenols in safflower seeds and safflower seed oil (SSO). The results showed that the introduction of MW-AE treatment prior to Ene-AE enhanced enzyme accessibility, resulting in MW + Ene-AE achieving the highest efficiency for polyphenol extraction from seeds, with a 67 % improvement compared to the control sample. Different treatments significantly altered the composition of polyphenols in the seeds, with a noticeable conversion of polyphenol glycosides to aglycones observed in Ene-AE and MW + Ene-AE.

Structural Characterization and Anti-inflammatory Activities of a Purified Polysaccharide from Veronica persica Poir.

In this manuscript, the polysaccharide (VPP-I) from Veronica persica Poir., was characterized in detail by high performance gel permeation chromatography (HPGPC), high performance liquid chromatography (HPLC), Fourier transform infrared spectroscopy (FT-IR) and nuclear magnetic resonance spectroscopy (NMR). In addition, lipopolysaccharide (LPS) induced inflammation model of RAW264.

Variation of Microbial Community and Fermentation Quality in Corn Silage Treated with Lactic Acid Bacteria and during Aerobic Exposure.

Silage, especially whole crop corn silage (WCCS), is an important part of ruminant diets, with its high moisture content and rich nutrient content, which can easily cause contamination by mold and their toxins, posing a great threat to ruminant production, food safety and human health. The objective of this study was to examine effects of lactic acid bacteria (LAB) () subsp. ZA3 and (AA) on the fermentation characteristics, microbial community and mycotoxin of WCCS during 60 days (d) ensiling and subsequent 7 d aerobic exposure.

The Effect of Selenium on CYP450 Isoform Activity and Expression in Pigs.

Selenium is an essential nutrient in diets; however, the effects of selenium on enzyme metabolic activation are not currently clear. Cytochromes P450 (CYP450) are major phase I metabolic enzymes involved in the biotransformation of xenobiotics and endogenous compounds to form electrophilic reactive metabolites. To investigate the effect of selenium on CYP450 isoform activity, the Landrace pigs were divided into three groups: the control group (containing Se 0.

Browning control of fresh-cut Chinese yam by edible coatings enriched with an inclusion complex containing star anise essential oil.

Star anise essential oil (SAEO) has a variety of antioxygenic and antimicrobial properties, and is widely used in food preservation. However, its application is still challenging due to poor water solubility and physicochemical stability. We now report that encapsulation of SAEO in hydroxypropyl-β-cyclodextrin (HPCD) enhances its water solubility, as well as its thermal, storage, and photostability.

Highly Selective and Considerable Subcritical Butane Extraction to Separate Abamectin in Green Tea.

We specially carried out the subcritical butane extraction to separate abamectin from tea leaves. Four parameters, such as extraction temperature, extraction time, number of extraction cycles, and solid-liquid ratio were studied and optimized through the response surface methodology with design matrix developed by Box-Behnken. Seventeen experiments with three various factors and three variable levels were employed to investigate the effect of these parameters on the extraction of abamectin.

Effective Subcritical Butane Extraction of Bifenthrin Residue in Black Tea.

As a natural and healthy beverage, tea is widely enjoyed; however, the pesticide residues in tea leaves affect the quality and food safety. To develop a highly selective and efficient method for the facile removal of pesticide residues, the subcritical butane extraction (SBE) technique was employed, and three variables involving temperature, time and extraction cycles were studied. The optimum SBE conditions were found to be as follows: extraction temperature 45 °C, extraction time 30 min, number of extraction cycles 1, and in such a condition that the extraction efficiency reached as high as 92%.

Extraction of Fenugreek (Trigonella foenum-graceum L.) Seed Oil Using Subcritical Butane: Characterization and Process Optimization.

In this study, the subcritical butane extraction process of fenugreek seed oil was optimized using response surface methodology with a Box-Behnken design. The optimum conditions for extracted oil from fenugreek seed was as follows: extraction temperature of 43.24 °C , extraction time of 32.

Process optimization and characterization of fragrant oil from red pepper (Capsicum annuum L.) seed extracted by subcritical butane extraction.

Background: Red pepper seeds account for 450-500 g kg of the total pepper weight and are often discarded as waste. In this study, process optimization and characterization of fragrant oil from roasted red pepper seed extracted by subcritical butane extraction were carried out.

Results: The optimal conditions of extraction were a temperature of 74.

[Mutation analysis of a Chinese family with genetic dentinogenesis imperfecta].

Objective: To study the genetic etiology of an autosomal dominant dentinogenesis imperfecta in a Chinese family.

Methods: The molecular change of the disease in the family was analyzed through the clinical examination, linkage analysis, mutational screening of the DSPP gene and restriction fragment length polymorphism analysis.

Results: The disease related gene was completely linked with microsatellite marker D4S1534.
