Experimental accelerated shelf life determination of a ready-to-eat processed food.

The most direct way to estimate the shelf life of a product is to conduct simulation tests which are time consuming and expensive. Conversely, accelerated shelf life tests can be successfully used for stable products having long expected shelf life. The aim of the study was directed to verify the possibility to apply an accelerated shelf life test to perishable food products having a short-expected shelf life, such as a new ready-to-eat processed food preparation, composed mainly by cereals, tuna and chicken, packed in thermo-sealed trays and pasteurised.

Indicators of protein spoilage in fresh and defrosted crustaceans and cephalopods stored in domestic condition.

In relation to consumer demand, crustaceans and cephalopods are sold as both fresh and defrosted. It is well known that total volatile basic nitrogen (TVB-N) and volatile amine values, especially, biogenic amines and biogenic amine index, are expression of freshness of fish products, but there is a lack of knowledge of their acceptability limits, for crustaceans and cephalopods. In order to assess these limits, real-time shelf life tests were carried out, relating the results of TVB-N, biogenic amines and BAI to the sensory evaluation of crustaceans and cuttlefishes, both fresh and defrosted.

Microbiological, chemical-physical and sensory characteristics of Fabriano salami from pigs fed extract.

This study aimed at evaluating the effect of extract supplementation of heavy pig diet on the microbiological, chemical-physical and sensory characteristics of Fabriano salami. Fabriano salamis were produced processing meat derived from pigs belonging to two dietary groups of 16 pigs each: CTRL group fed a commercial pelleted feed, and OR group fed the CTRL diet integrated with 0.2% of oregano extract.

Evaluation of antibiotic usage in swine reproduction farms in Umbria region based on the quantitative analysis of antimicrobial consumption.

Antibiotic use in food-producing animals has considerable impact on public health, especially with respect to the development and spread of antibiotic resistance. Pigs represent one of the main species in which antibiotics are frequently used for different purposes. Surveillance of antibiotic consumption and dose appropriateness, through novel approaches based on , is strongly needed to assess farms' antibiotic risk, in terms of spread of antibiotic resistance and possibile presence of residues in meat.

Contribution of street food on dietary acrylamide exposure by youth aged nineteen to thirty in Perugia, Italy.

Acrylamide dietary intakes from selected street foods in youth population are estimated. The intake evaluation was carried out by combining levels of acrylamide in food, analytically determined by high performance liquid chromatography, with individual consumption data recorded using a questionnaire applied to a group of 200 students aged 19 to 30. The mean value of acrylamide exposure was recorded to be 0.

Study of Acrylamide Level in Food from Vending Machines.

Acrylamide is a by-product of the Maillard reaction and is potentially carcinogenic to humans. It is found in a number of foods with higher concentrations in carbohydrate-rich foods and moderate levels of protein-rich foods such as meat, fish and seafood. Acrylamide levels in food distributed in vending machines placed in public areas of the city of Perugia were analysed by high-performance liquid chromatography.

Occurrence of Parasites of the Genus spp. (Nematoda: Dioctophymatidae) in Fish Caught in Trasimeno Lake, Italy.

spp. is considered a freshwater fish zoonotic nematode. In the present study, the prevalence of spp.

Thermal Inactivation and Growth Potential of in Smoked Tench.

An experimental study for the evaluation of inactivation during a hot smoking process in tench was performed using strains. Furthermore, the survival of in smoked tench was determined after post-processing in contaminated samples, evaluating the growth potential during storage. was not detected after the smoking process.

Antimicrobial Activity of Olive Mill Wastewater Extract Against Isolated from Mozzarella Cheese.

Olive mill wastewater polyphenol extract was tested for antimicrobial activity against 64 strains of responsible for mozzarella discolouration. The extract showed a minimum inhibitory concentration (MIC) value of 5 mg/mL and a MIC value of 7 mg/mL. The MBC and MBC values corresponded to 6 and 8 mg/mL, respectively.

Behaviour of in Artisanal Raw Milk Cheese: A Microbiological Challenge Test.

In the present study, a microbiological challenge test in artificially contaminated raw milk cheese during cheese-making was carried out. Raw ewe milk was contaminated by a suspension of particular strains. The number of and dynamic growth were evaluated during cheese-making and storage.

Role of Verocytotoxigenic Escherichia Coli in the Swine Production Chain.

Shiga toxin-producing Escherichia coli (STEC) can cause severe clinical diseases in humans, such as haemorrhagic colitis (HC) and haemolytic-uremic syndrome (HUS). Although ruminants, primarily cattle, have been suggested as typical reservoirs of STEC, many food products of other origins, including pork products, have been confirmed as vehicles for STEC transmission. Only in rare cases, pork consumption is associated with severe clinical symptoms caused by high pathogenic STEC strains.

Foreign Bodies in Dried Mushrooms Marketed in Italy.

The presence of foreign bodies in mushrooms affects their marketability and may result in health risks to consumers. The inspection of fresh or dried mushrooms today is very important in view of the increased consumption of this kind of food. Ten samples of dried mushrooms collected in supermarkets were examined for evidence of entomological contamination by macro and microscopic analytical methods, the so-called .
