Microorganisms which contaminate animal feeds pose a threat not only to animals but also indirectly to humans through their consumption of products of animal origin. The aim of the present study was to assess microbiological cleanness of selected resources and ready-made feed mixtures before and after thermal processing. The results indicated that the most bacteriologically contaminated resourc...

Concerns about traces of numerous toxic substances and authenticity have prompted consumer demand for honey that is certified as organic, based on strict ecological, natural principles and traceability. The present study aims to characterize organic honey samples (n = 73) from Northeast Portugal, with respect to floral nectar origin, physicochemical parameters and microbial safety. The phenols ...

This study aimed to design high-quality and safe spreadable processed cheese with a prolonged shelf life appropriate for logistic support in emergency/crisis situations, foreign missions, and/or state material reserves. Samples dry matter content (DM) of 30–55 g/100 g fat (FDM) 30–50 were produced, hermetically sealed sterilised at 120 °C 40 min. The microbiological, chemical, textural, viscoel...

the objective of this study was to assess the microbial contamination of razavi khorasan (iran) hot red pepper. the natural occurrence of aflatoxins and ochratoxin a in those samples was also investigated. for this purpose, 36 samples of this kind of pepper were collected from a farm and sun-dried. standard and established methods were used for both microbiological analyses and mycotoxins ident...

In this study, the influence of different treatments was evaluated: nonwashing, washing in chlorinated water and washing/soaking in chlorinated water and sodium chloride on the quality of Nile tilapia (Oreochromis niloticus) fillets during storage at 1.0 ± 0.5°C through daily analysis of pH, moisture, and lipids content. Microbiological analysis and growth modeling for mesophilic and psychrotro...

Milk powders are hygroscopic: they tend to attract water readily from humid atmospheres. When moisture levels are excessive, milk powders may become sticky, caked or lumpy, and exhibit reduced flowability and solubility. These changes affect the ease of use of the product, requiring grinding for example and may affect the flavor, but do not represent a health or safety problem. If the powder’s ...

One of the oldest unresolved microbiological phenomena is why only a small fraction of the diverse microbiological population grows on artificial media. The "uncultivable" microbial majority arguably represents our planet's largest unexplored pool of biological and chemical novelty. Previously we showed that species from this pool could be grown inside diffusion chambers incubated in situ, like...

Household water treatment using sodium hypochlorite (NaOCl) has been recognized as a cost-effective means of reducing the heavy burden of diarrhea and other waterborne diseases, especially among populations without access to improved water supplies. Sodium dichloroisocyanurate (NaDCC), which is widely used in emergencies, is an alternative source of chlorine that may present certain advantages ...
