Effect of ascorbic acid, oxygen and storage duration on patulin in cloudy apple juice produced on a semi-industrial scale Research Institute for Agriculture, Fisheries and Food

Christelle El Hajj Assaf, Nikki De Clercq, Estelle De Paepe, Geertrui Vlaemynck, Els Van Coillie, Els Van Pamel
Patulin (PAT), a mycotoxin mainly produced by Penicillium expansum, is of high concern with regard to human food safety. This study examined the stability of PAT in artificially contaminated cloudy apple juice (CAJ) produced on a semi-industrial scale using an innovative technology allowing degassing and pressing under low-oxygen conditions (VaculIQ 1000). The effects of adding ascorbic acid (AA), degassing during production and storing in the ...

Possible effects of probiotic strains on suppression of Vibrio and enhancement of growth in rotifer, Brachionus plicatilis Ghent University

J. Sahandi, Patrick Sorgeloos, H. Xiao, H. Wang, Z. Qi, Y. Zheng, X. Tang
Because of the importance of rotifers as an adequate live food in larviculture, this study was conducted to evaluate probiotic potency of four microorganisms, Candida parapsilosis, Pseudoalteromonas flavipulchra, Lactobacillus sakei and Bacillus natto on suppression of Vibrio species and increasing population growth, enzymes activity and nutrients retention in the rotifer, Brachionus plicatilis. Four experimental and a control treatment, each ...

Biotransformation to produce the anticancer compound colchicoside using cell suspension cultures of Astragalus vesicarius plant species University of Antwerp

Yancho Zarev, Pavlinka Popova, Kenn Foubert, Arnold Vlietinck, Luc Pieters, Iliana Ionkova
This paper discusses the biotechnological process affected by means of plant suspension cultures, for production of colchicoside, the 3-O-glucosyl derivative of 3-O-demethylcolchicine. Colchicoside can be considered as an antitumoural prodrug which is activated after oral administration and may have more beneficial effects and a better toxicity profile (because of a slow-release effect) than colchicine. We have developed a green and efficient ...

Examining the relationship between chain governance structures and chain performance : an empirical evidence of the dairy sector Ghent University

Joanita Kataike, Adrienn Molnar, Hans De Steur, Xavier Gellynck
Purpose: The purpose of this paper is to analyze the influence of chain governance on chain performance among the chain members.Design/methodology/approach: The survey was conducted in a triadic context with 345 chain members (115 dairy farmers, 115 dairy cooperative managers, and 115 processors) of the dairy sector in Uganda. Data collection was performed through simple random sampling by survey questionnaires with the chain executives. SEM was ...

The economic value of information provided by milk biomarkers under different scenarios Research Institute for Agriculture, Fisheries and Food

Cristina Rojo Gimeno, Veerle Fievez, Erwin Wauters
Monitoring systems (MS) provide additional information that many developers and researchers expect will reduce the uncertainty surrounding decision-making in livestock production and therefore enhance management decisions. However, the actual economic value of the information (VoI) yielded by MS has hardly been investigated. The aim of this study was to fill that void based on two objectives. The first is to estimate the VoI of MS prior to ...
