Toddlerhood (aged 13~36 months) is a period of dietary transition, with water intake being significantly influenced by parental feeding patterns, cultural traditions, and the availability of beverages and food. Nevertheless, given the lack of applicable data, it is challenging to guide and evaluate the water intake of toddlers in China. In this stu...

Background: Adequate water intake in pregnant women plays an important role in their health and in fetal growth and development. However, there is insufficient applicable data to guide and evaluate the water intake of pregnant women in China. Based on a nationwide sample of pregnant women, we mainly aimed to investigate the daily total water intak...

Background: The nutritional status of lactating mothers (LMs) is related to their own health and significantly impacts the secretion of breast-milk, and subsequently the growth and development of infants. Due to the influence of regional economy, traditional habits, and lack of nutrition knowledge, the problem of poor dietary nutrition among Chine...

Chlorogenic acids (CGAs) are potent antioxidants found in certain foods and drinks, most notably in coffee. In recent years, basic and clinical investigations have implied that the consumption of chlorogenic acid can have an anti-hypertension effect. Mechanistically, the metabolites of CGAs attenuate oxidative stress (reactive oxygen species), whic...

A TaqMan real-time PCR assay was developed to quantify the tetS gene pool present in retail cheeses. This protocol offers a rapid, specific, sensitive, and culture-independent method for assessing antibiotic resistance genes in food samples rich in fats and proteins.

The rapid emergence of antibiotic-resistant (ART) pathogens is a major threat to public health. While the surfacing of ART food-borne pathogens is alarming, the magnitude of the antibiotic resistance (AR) gene pool in food-borne commensal microbes is yet to be revealed. Incidence of ART commensals in selected retail food products was examined in th...

The rapid emergence of antibiotic resistant (ART) pathogens is a major threat to public health. While the surfacing of ART foodborne pathogens is alarming, the magnitude of the antibiotic resistance (AR) gene pool in foodborne commensals is yet to be revealed. Incidence of ART commensals in dairy, meat, seafood and produce products was examined in...

The importance of conjugation as a mechanism to spread biofilm determinants among microbial populations was illustrated with the gram-positive bacterium Lactococcus lactis. Conjugation triggered the enhanced expression of the clumping protein CluA, which is a main biofilm attribute in lactococci. Clumping transconjugants further transmitted the bio...

The thermophilic, aciduric Alicyclobacillus spp. are becoming an increasing spoilage concern in the beverage industry. Rapid methods to detect their presence in both raw materials and final products are desirable for industrial quality control. The objective of this study was to develop a real-time TaqMan-based polymerase chain reaction (PCR) syste...

To develop a real-time PCR-based rapid detection method for spoilage Alicyclobacillus spp. in juice products. The squalene-hopene cyclase-encoding gene was targeted for primer-and-probe development. Gene fragments from representative strains were cloned, and PCR primers and probe were designed by DNA sequence comparison. Selected bacteria were exam...

The purpose of this research was to develop a system for cultivating and evaluating Listeria monocytogenes biofilms that produces consistent and reliable results. A three-tiered approach was used to evaluate biofilm-forming abilities of three L. monocytogenes strains that were originally associated with listeriosis outbreaks. A L. monocytogenes 'ho...
