Flaxseed is an oilseed with many health benefits. Flaxseed may be consumed raw or in processed form. In the raw form, there is a potential for microbial contamination. Several pasteurization methods have been used to reduce microbial contamination. However, such treatments may affect chemical properties of foods. In this study, vacuum steam-pasteurization was conducted on whole flaxseed and milled flaxseed using 4 different conditions (3 min at 75 °C, 3 min at 90 °C, 9 min at 90 °C, and 3 min at 105 °C)...

Uwe T Bornscheuer
This article reviews the application of enzymes in lipid modification. Lipases are the most established biocatalysts used for the synthesis of structured triacylglycerols, fats, and margarine for the release of flavoring fatty acids for food applications. In addition, the various enzymes, such as P450 monooxygenases, hydratases, lipoxygenases, and certain lyases, used for oxyfunctionalization and the phospholipases used for degumming are covered. Basic aspects of enzyme catalysis and the modern tools used for their discovery and improvement by protein engineering provide insight into how suitable biocatalysts can be identified and optimized for an application...

Listeriosis outbreaks are frequently multistate/multicountry outbreaks, underlining the importance of molecular typing data for several diverse and well-characterized isolates. Large-scale whole-genome sequencing studies on Listeria monocytogenes isolates from non-U.S. locations have been limited. Herein, we describe the draft genome sequences of 510 L. monocytogenes isolates from northern Italy from different sources.

Annunziata D'Alessandro, Giovanni De Pergola
We have analysed the definition of Mediterranean Diet in 28 studies included in six meta-analyses evaluating the relation between the Mediterranean Diet and primary prevention of cardiovascular disease. Some typical food of this dietary pattern like whole cereals, olive oil and red wine were taken into account only in a few a priori indexes, and the dietary pattern defined as Mediterranean showed many differences among the studies and compared to traditional Mediterranean Diet of the early 1960s. Altogether, the analysed studies show a protective effect of the Mediterranean Diet against cardiovascular disease but present different effects against specific conditions as cerebrovascular disease and coronary heart disease...

High prevalence numbers of extended-spectrum beta-lactamase- (ESBL-)/plasmid-mediated AmpC beta-lactamase- (pAmpC-) producing Escherichia coli in broiler chicken and their distribution along the broiler production chain is an ongoing problem in food production. We, therefore, investigated resistant isolates along the broiler production chain to determine whether there is a constantly occurring direct vertical transmission of the ESBL-/pAmpC-producing E. coli from the parent flocks to their offspring or not...

Public health and food safety institutions around the world are adopting whole genome sequencing (WGS) to replace conventional methods for characterizing Salmonella for use in surveillance and outbreak response. Falling costs and increased throughput of WGS have resulted in an explosion of data, but questions remain as to the reliability and robustness of the data. Due to the critical importance of serovar information to public health, it is essential to have reliable serovar assignments available for all of the Salmonella records...

BACKGROUND: The quality of most Americans' diets is far from optimal. Given that many Americans consume a significant portion of calories in the home, intervening in this setting could be beneficial. However, the relationship between the home food environment and diet quality is not well understood. This study examined the relationship between diet quality at the individual level with home-level diet quality using an index that measures compliance with federal dietary guidance. METHODS: This was a cross sectional study that enrolled 97 African American and Hispanic/Latino low-income parent-child dyads...

Diseases triggered by microorganisms can be controlled by vaccines, which need neutralizing antigens. Hence, it is very crucial to identify extremely efficient immunogens for immune prevention. Botulism, a fatal neuroparalytic disease, is caused by botulinum neurotoxins produced by the anaerobic, Gram-positive spore-forming bacteria, Clostridium botulinum. Food-borne botulism and iatrogenic botulism are caused by botulinum toxin. Wound botulism, infant botulism, and adult intestinal botulism are caused by primarily C...

Strawberry is a major natural source of bioactive compounds. Botanically, strawberry is an aggregate fruit consisting of a fleshy floral receptacle that bears a cluster of real dry fruits (achenes). Existing knowledge on the phenolic composition of achenes and its contribution to that of the whole fruit is limited. Also, the gastric and intestinal bioavailability of phenols is poorly known. In this work, a combination of spectrophotometric and HPLC-DAD methods was used to analyse the phenolic composition of whole fruits and achenes before and after in vitro digestion...
