Blueberries are commonly consumed in processed forms, but limited information is available on how different processing methods and storage of processed products impact the polyphenolic content of the fruit. In this study, we determined how canning, puréeing and juicing of blueberries, as well as storage of processed products at 25°C, influenced the retention of chlorogenic acid, total flavonols...

BACKGROUND Numerous cross-sectional studies have examined neighborhood effects on health. Residential selection in adulthood has been stressed as an important cause of selection bias but has received little empirical attention, particularly its determinants from the earlier life course. The present study aims to examine whether neighborhood, family, school, health behaviors and health in adoles...

This article develops a method to estimate the impact of change in a particular social setting, the residential neighborhood, that is designed to address nonrandom selection into a neighborhood and nonrandom selection out of a neighborhood. Utilizing matching to confront selection into neighborhood environments and instrumental variables to confront selection out of changing neighborhoods, the ...

Due to high prevalence rates and deleterious effects on individuals, families, and communities, intimate partner violence (IPV) is a significant public health problem. Because IPV occurs in the context of communities and neighborhoods, research must examine the broader environment in addition to individual-level factors to successfully facilitate behavior change. Drawing from the Social Determi...

The aim of this study is to investigate the novel application of a ‎handheld near infra-red spectrophotometer coupled with classification methodologies as a screening approach in detection of adulterated lime juices. For this purpose, a miniaturized near infra-red spectrophotometer (Tellspec®) in the spectral range of 900–1700 nm was used. Three diffuse reflectance spectra of 31 pure...

Antioxidant activity of asparagus, broccoli and their juices was evaluated using 2,20-diphenyl-l-picrylhydrazyl (DPPH), 2,20-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and b-carotene bleaching assays. Asparagus showed greater antioxidant activity than broccoli. Asparagus juice also had greater antioxidant activity than broccoli juice. Methanol and acetone extracts of asparagus and ...

Membrane technology for the processing of fruit juices and beverages has been applied mainly for clarification using ultrafiltration and microfiltration, and for concentration using reverse osmosis. The effects of product preparation, membrane selection, and operating parameters are important factors influencing filtration rate and product quality. Technological advances related to the developm...

The occurrence of nonenzymaticbrowning in fruit juices during storage is a major quality defect. It negatively affects consumer acceptance and consumption behavior determines the shelf-life these products. Although nonenzymatic browning has been subject research for long time, exact mechanism reactions not yet completely understood. This review paper aims to give an overview compounds playing k...

the aim of this study was to evaluate the performances of methods such as sequencing of the internal transcribed spacer (its) and 26s (d1/d2) regions of ribosomal dna, rflp analysis of the its region and commercial biochemical test kit for the identification of the yeasts isolated during spontaneous fermentation of fresh crushed pineapple juice. the experiments were conducted in thailand and au...
