The present study examined the effect of Lactobacillus plantarum ATCC14917 fermentation on chemical composition and antioxidant activity apple juice. Apple juice was fermented its using models cellular assay. Furthermore, characterized by LC-MS/MS. showed an increase in DPPH ABTS radical scavenging as well However, decreased total phenolic flavonoid content. Subsequent LC-MS/MS analysis profile indicated that content 5-O-caffeoylquinic acid (5-CQA), quercetin, phloretin with strong increased...
To determine the true community prevalence of human cystic (CE) and alveolar (AE) echinococcosis (hydatid disease) in a highly endemic region Ningxia Hui, China, by detecting asymptomatic cases.Using hospital records "AE-risk" landscape patterns we selected study communities predicted to be at risk Guyuan, Longde Xiji counties. We conducted surveys 4773 individuals from 26 villages 2002 2003 using questionnaire analysis, ultrasound examination serology.Ultrasound serology showed range...
Changes in key odorants and aroma profiles of three types green tea during storage after baking treatment were determined using headspace solid-phase microextraction–gas chromatography–mass spectrometry/olfactometry, odor activity value (OAV) orthogonal partial least-squares discriminant analysis. As the stale developed storage, content aldehydes decreased, whereas contents ketones heterocycles (furans, pyrroles, etc.) increased. Key odorants, including (E,E)-2,4-heptadienal, α-terpineol,...
This paper applies near-infrared spectroscopy (NIRS) and multiple chemometrics to efficiently distinguish the origins of fresh tea leaves. The key components were obtained using partial least squares discriminant analysis (PLS-DA) method. PLS, synergy interval PLS (siPLS), principal component (PCA), genetic algorithm (GA), their combination methods used establish NIRS non-destructive discrimination models. Then, practical application was examined external samples. study identified nine...
Fresh leaves of Echa 1 were fixed by roller, steam/hot air and light-wave, the effects three fixation methods on chemical characteristics straight-shaped green teas (GTs) studied widely targeted metabolomic analysis. 1001 non-volatile substances was identified, from which 97 differential metabolites selected criteria variable importance in projection (VIP) > 1, p < 0.05, |log2(fold change)| 1. Correlation analysis indicated that 14 taste-active major contributors to taste differences between...
Abstract BACKGROUND It is well known that plant essential oils have good antimicrobial activity. However, their strong volatility and intense odor limit application. Mesoporous silica (MCM‐41), a non‐toxic mesoporous material with excellent loading capability, promising delivery system for different types of food ingredients in the industry. RESULTS In this study, we first performed component analysis pepper fragrant oil (PFEO) by gas chromatography – mass spectrometry (GC–MS), then MCM‐41...
Summary Objective To assess the usefulness of serology as an indicator Echinococcus transmission for developing preventive measures against echinococcosis in rural communities. Methods Cross‐sectional survey 2002 among 861 children aged 7 to 18 years Xiji County, Ningxia, China. Before ultrasound abdominal examination, a questionnaire was used identify socioeconomic, sanitary and hygiene risk factors echinococcal infection; filter paper blood samples were collected from each child specific...
As one of the dominant reactions occurring during thermal treatment food, Maillard reaction not only leads to formation aroma, browning color and taste compounds, but also contributes some unpleasant toxic substances including acrylamide, heterocyclic amines advanced glycation end products. Polyphenols, most abundant antioxidants in human diet, are contained different kinds foods. In this review, recent studies on impact dietary polyphenols products formed summarized, research work conducted...
Summary We correlated ultrasound (US) imaging classifications for human alveolar echinococcosis (AE) and cystic (CE) with serology (ELISA immunoblotting (IB) incorporating native recombinant/purified echinococcal antigens) in community surveys (2001–2003) follow‐up (2002 2003) of US‐confirmed cases Ningxia, China. One hundred seventy‐one (96 AE, 75 CE) were identified; these, US classification serological data obtained 142 112 cases, respectively. Seropositive‐rates increased CE patients...
Epigallocatechin gallate (EGCG) has been recognized as the most prominent green tea extract due to its healthy influences. The high instability and low bioavailability, however, strongly limit utilization in food drug industries. This work, for first time, develops amorphous solid dispersion of EGCG enhance bioavailability physical stability. Four commonly used polymeric excipients are found be compatible with water-dioxane mixtures via a stepwise mixing method aided by vigorous mechanical...
Advanced glycation end products (AGEs) excessive accumulation in the body either by exogenous intake or endogenous formation makes individuals prone to oxidative stress and inflammation damage. In this study, DCFH-DA fluorescence test qPCR experiment were carried out study effect of some dietary flavonoids on AGEs induced toxicity. Among four tested flavonoids, it was found that hesperetin could significantly inhibit both AGEs-induced ROS production gene expressions TNF-α, IL-1β, IL-6,...
Recently, there is a growing interest in fortifying food products with flavonoids to enhance health benefits. Naringenin, naringin, hesperetin, and dihydromyricetin are four typical constituting natural part of our diet. In the present work, they were fortified into chia oil cookie model evaluate their thermal stability during baking as well impact on antioxidant capacity toxicant formation. Among them was most unstable one (only 36.1% which left after at 180 °C for 20 min) led loss...
Tea polyphenols are one of the most important ingredients in Qingzhuan tea. Usually, a chemical method is used to determine tea content, but it was time-consuming and laborious. This paper attempted use near infrared spectroscopy (NIRS) technology combined with three partial least squares methods predict content quickly nondestructively. The (PLS), synergy interval PLS (siPLS) genetic algorithm based (gaPLS) were establish prediction models, performance final model showed by root mean square...
In this study, the quality of spiral cold press chia seed oil was evaluated and four types O/W nanoemlusion systems were prepared, including nanoemulsion stabilized with Tween 80 Span by spontaneous emulsification microfluidization, sodium caseinate sucrose monopalmitate microfluidization. All these optimized samples exhibited good storage stability for at least two weeks when stored 4 °C or ambient temperature. The labeling friendly, enough energy-input facilitated achievement small...
A rapid and nondestructive near-infrared diffuse reflectance spectroscopy method combined with multivariate analysis was developed to discriminate different species grades of marine fish surimi. Principal component discriminant were applied classify the quality The results showed that excellent classification obtained after optimizing spectral pretreatment. For discrimination three surimi, correct rate calibration as well validation datasets 98.5% 100%, respectively, using multiplicative...
