Toxicology Reports Volume 7, 2020, Protective Effect of Yemeni Green Coffee Powder Against the Oxidative Stress Induced by Ochratoxin A. 1. Introduction Coffee beans cultivation in tropical and sub-tropical countries [1]. Coffee is world’s popular beverages traded and consumed food commodity [2]. Coffee is a complex drink containing, 1000 compounds other than caffeine, its lovely flavor, and aroma [3]. In the human diet, it is a source of caffeoyl‐quinic acids known as intense antioxidant agents [4]. Our interest is to find out the potential antioxidant activity of this Yemeni green coffee against the oxidative stress produced after induction using toxin. 2. 2.1. Yemeni green coffee beans (Coffea Arabica) were procured from Yemen Standardization Metrology and Quality Control Organization (YSMQCO), Yemen, 70 samples of Yemeni green coffee beans (Coffea arabica L.), were collected YSMQCO from many local places in some Yemeni Governorates during 2010/2011. 2.2. 2.3.

JOURNAL OF FOOD SAFETY 02/12/18 Evaluation of the effects of temperature on processed coffee beans in the presence of fungi and ochratoxin A. The coffee bean is sensitive to contamination with ocratoxigenic fungi; temperature influences the growth, and germination of these fungi, as well as the fungal toxins produced. The objectives of this study were to assess the distribution of toxigenic species, analyze the concentration of ochratoxin A (OTA) in Arabica coffee beans, and aplicate a mathematical model that considers the influence of actual temperature to predict the effects of projected temperature increase on OTA production.

This toxin was, however, not detected in any of the coffee bean species analyzed here. The species with the highest incidence were Aspergillus niger and A spergillus ochraceus . The results of the mathematical model demonstrated the influence of temperature on the production of the toxin. This information indicates the distribution of toxigenic fungal species in the regions of coffee cultivation in Minas Gerais, and thus, will assist the producers in adopting preventive measures.

Extras (1) Multimedia component 1 Highlights The concentration and occurrence of OTA in coffee and coffee-based products was investigated. Ninety four studies was included in the meta-analysis and meta-regression. The global pooled concentration of OTA was 3.21 μg/kg (95% CI: 3.08–3.34 μg/kg). The global pooled prevalence of OTA was 53 % (95% CI: 43–62). With increasing in poverty and decreasing in HDI, prevalence of OTA increased.

With increasing in poverty as well as annual rain and decreasing in HDI, prevalence of OTA increased. Abstract The current investigation was aimed to estimate the prevalence and concentration of ochratoxin A (OTA) in different types of coffee and coffee-based products with the aid of a systematic review and meta-analysis.

ACADEMIC JOURNALS - NOV 2016 - Assessment of Ochratoxin A intake due to consumption of coffee and cocoa derivatives marketed in Abidjan (Côte d’Ivoire) Ochratoxin A is a mycotoxin produced by moulds belonging to the Aspergillus and Penicillium species, and is a common contaminant of various food products.

Ochratoxin A is known for its nephrotoxic and carcinogenic effects; protective actions to protect consumer health must be established. The aim of this study was to assess the level of contamination of manufactured coffee and cocoa-based products marketed in Abidjan to estimate ochratoxin A intake related to the consumption of these goods. We quantified ochratoxin A in 87 samples by high-performance liquid chromatography with fluorescence detection. Coffee samples contained an average of 4.0 ± 3.4 µg/kg ochratoxin A and cocoa-based industrial products 0.9 ± 0.6 µg/kg. OTA intakes were assessed using data obtained from the analysis and the estimated Ivorian adult daily consumptions. Key words: Product derivatives, coffee, cocoa, ochratoxin A.

Open Access Highlights This study evaluated the reduction of ochratoxin A during roasting of coffee beans. The reduction of ochratoxin A varied from 56 to 97%. The type of roasting and particle size interfere in the residual content of OTA. Abstract Contamination of roasted coffee with ochratoxin A (OTA) is directly related to the processing quality throughout the coffee production chain, from the farming to the roasting processes.

The aim of this study was to evaluate the effects of roasting and particle size on the residual concentration of ochratoxin A in roasted and ground coffee. Keywords Roasting; Particle size; Ochratoxin A; Food safety 1. The development of microbial infections in coffee beans may compromise both their visual appearance and their taste and aroma. Coffee bean contamination with ochratoxin A may occur throughout the entire production chain and is directly related to the care and quality of the crop management, harvest, post-harvest storage and type of roasting. 2. 2.1.

COFFEE-OTA_ORG - Réduire la teneur d'ochratoxine A dans le café. Coffee is one of the most valuable primary products in world trade, being second in value only to oil as a source of foreign exchange to developing countries. Its cultivation, processing, trading, transportation and marketing provide employment for millions of people worldwide. Any disruption to trade in coffee would have major and direct negative implications for the livelihoods of rural populations in many developing countries. Around 2000, there was increasing international attention to the problem of ochratoxin-A (OTA) contamination in coffee and its public health implications.

OTA is one of several naturally occurring toxins, known as mycotoxins, which are produced by moulds that grow on crops in the field or in storage. Regulatory authorities in some coffee importing countries initiated work on the development of proposed maximum levels of OTA contamination in green coffee. The training tool on Good Hygiene Practices along the coffee chain is available here. PROGRAMME MIXTE FAO/OMS SUR LES NORMES ALIMENTAIRES - COMMISSION DU CODEX ALIMENTARIUS - Trente et unième session - Genève (Suis. EUROPE 13/10/04 Le café, le vin et le jus de raisin désormais couverts par les règles de l'UE concernant l'ochratoxine A. Bruxelles, le 13 octobre 2004 Le comité permanent de la chaîne alimentaire et de la santé animale s’est prononcé hier en faveur d’une proposition de la Commission européenne visant à modifier le règlement (CE) n° 466/2001 afin de fixer une teneur maximale en ochratoxine A pour le café, le vin et le jus de raisin. L'ochratoxine A est une mycotoxine dont les propriétés cancérigènes et toxiques sont avérées.

Des teneurs maximales ont déjà été établies pour ce contaminant en ce qui concerne les principales sources d’exposition de la population de l’UE, principalement les céréales, mais le suivi permanent a révélé qu'il conviendrait désormais d'en déterminer également pour d'autres sources alimentaires importantes. "En fixant des teneurs maximales en ochratoxine A, nous faisons en sorte que les consommateurs puissent boire du café et du vin sans s’inquiéter d’une éventuelle contamination.
