C Jans, D W Mulwa Kaindi, L Meile
Food preservation makes a significant contribution to food security and food safety in pastoral communities with limited access to external food sources. Raw materials are preserved by heating, drying, smoking, pickling, salting, curing or fermentation with microorganisms. This article describes preservation techniques in the pastoral context, targeting the major dietary components of milk, meat and cereals; related health risks; and potential innovations for food preservation. Sustainable elimination of pathogenic microorganisms, preventing re-contamination, sporulation and the growth of zoonotic and foodborne microorganisms, is necessary to enhance food safety and ensure food security by reducing post-harvest losses and food waste...

Rapid detection of target bacteria is crucial to provide a safe food supply and to prevent foodborne diseases. Herein, we present an optical biosensor for identification and quantification of Escherichia coli (E. coli, used as a model indicator bacteria species) in complex food industry process water. The biosensor is based on a nanostructured, oxidized porous silicon (PSi) thin film which is functionalized with specific antibodies against E. coli. The biosensors were exposed to water samples collected directly from process lines of fresh-cut produce and their reflectivity spectra were collected in real time...

Salmonella Typhimurium and Cronobacter sakazakii are two foodborne pathogens involved in neonatal infections from milk powder and infant formula. Their ability to survive in low-moisture food and during processing from the decontamination to the dried state is a major issue in food protection. In this work, we studied the effects of the drying process on Salmonella Typhimurium and Cronobacter sakazakii, with the aim of identifying the drying parameters that could promote greater inactivation of these two foodborne pathogens...

Entomophagy has been linked to nutritional, economic, social and ecological benefits. However, scientific studies on the potential safety risks in eating edible insects need to be carried out for legislators, markets and consumers. In this context, the microbiota of edible insects deserves to be deeply investigated. The aim of this study was to elucidate the microbial species occurring in some processed marketed edible insects, namely powdered small crickets, whole dried small crickets (Acheta domesticus), whole dried locusts (Locusta migratoria), and whole dried mealworm larvae (Tenebrio molitor), through culture-dependent (classical microbiological analyses) and -independent methods (pyrosequencing)...

Bacteriophages are viruses capable of infecting and lysing target bacterial cells; as such they have potential applications in agriculture for decontamination of foods, food contact surfaces and food rinse water. Although bacteriophages can retain infectivity long-term using lyophilized storage, the process of freeze-drying can be time consuming and expensive. In this study, electrospinning was used for dehydrating bacteriophages in polyvinylpyrrolidone polymer solutions with addition of excipients (sodium chloride, magnesium sulfate, Tris-HCl, sucrose) in deionized water...

Hydropeaking as a result of peak-load electricity production has been identified as one of the most significant pressures in alpine streams. Scouring of macroinvertebrates leads to downstream transport of aquatic organisms (catastrophic drift). Additionally, invertebrates are affected by periodic drying of wetted area during the dewatering of gravel bars and exposed areas along the banks. Even though fish are physiologically better adapted to switch to suitable habitats, artificial flow fluctuations may be followed by lethal stranding and quick alteration in habitat quantity and quality...

Over the past years, there has been a growing interest in the natural constituents of foods as a potential means of cancer control. To date, epidemiology studies seem to indicate an inverse association between regular consumption of fruit and vegetables and cancer risk. Here, the potential chemopreventive activity of the polyphenolic extract (PPE) of peach (Prunus persica L. Batsch) and of the freeze-dried fruit in toto (LFT), focusing on the modulation of xenobiotic metabolizing enzymes (XMEs) in vivo, was investigated...

Cadmium can enter water, soil and food chain in amounts harmful to human health by industrial wastes. The use of intact and NaOH-treated dried algal tissues (Hydrodictyon reticulatum); a major ecosystem bio-component, for Cd removal from aqueous solutions was characterized. Cadmium biosorption was found to be dependent on solution pH, bioadsorbent dose, the interaction between pH and dose, contact time, and initial Cd concentration. The experimental results indicated that the biosorption performance of alkaline-treated algal tissues was better than that of intact tissues...

Piper Betle L. (PB) belongs to the Piperaceae family. The presence of a fairly large quantity of diastase in the betel leaf is deemed to play an important role in starch digestion and calls for the study of weight loss activities and metabolite profile from PB leaf extracts using metabolomics approach to be performed. PB dried leaves were extracted with 70% ethanol and the extracts were subjected to five groups of rats fed with high fat (HF) and standard diet (SD). They were then fed with the extracts in two doses and compared with a negative control group given water only according to the study protocol...

Kusaya is a salted, dried fish product traditionally produced on the Izu Islands in Japan. Fish are added to kusaya gravy repeatedly and intermittently, and used over several hundred years, which makes unique microbiota and unique flavors. In this study, we performed a metagenomic analysis to compare the composition of the microbiota of kusaya gravy between different islands. Twenty samples obtained from a total of 13 manufacturers on three islands (Hachijojima, Niijima, and Oshima Islands) were analyzed. The statistical analysis revealed that the microbiota in kusaya gravy maintain a stable composition regardless of the production steps, and that the microbiota are characteristic to the particular islands...
