This article shows how we can simply develop functional green packaging of PLA for food with effective and efficient antimicrobial activity by use of LAE coating on the surface via corona discharge.Practical Application: The effectiveness of an innovative antimicrobial LAE‐coated PLA film against foodborne pathogens was demonstrated. Importantly, the application of the LAE to form the LAE‐coated PLA film can be customized within current film manufacturing lines. (Source: Journal of Food Science)

E. Coli O157:H7 Population Reduction from Alfalfa Seeds with Malic Acid and Thiamine Dilauryl Sulfate and Quality Evaluation of the Resulting SproutsEmail this article to a colleague.

Discuss or comment on this article.
The objectives of this research were to examine the efficacy of malic acid (MA) and thiamine dilauryl sulfate (TDS) combined treatments on the inactivation of E. coli O157:H7 on alfalfa seeds, to study the growth of the remaining E. coli cells during sprouting, and to evaluate the sprout quality. When 10 g of inoculated alfalfa seeds were washed in a 10% MA‐1% TDS solution, a complete elimination of E. coli was achieved. The same result was observed by washing the seeds in a 20000 ppm Ca(OCl)2 solution. However, when the seed size was increased to 50 g while maintaining the same seed‐to‐sanitizer ratio, both the MA +...

Abstract: The demand for gluten‐free bread is growing as the recognition of celiac disease and wheat allergy has increased worldwide. In our previous study, reduced glutathione (GSH) was found to improve the gas‐retaining properties of rice batter used for gluten‐free bread. In this article, oxidized glutathione (GSSG) was shown to have the same effect. Moreover, sensory tests revealed that GSSG bread had a significantly reduced sulfurous odor. Analyses by a gas chromatography‐flame photometric detector demonstrated the presence of hydrogen sulfide and methyl mercaptan in the headspace of GSH bread, and also the...

Effects of Cyclodextrins on the Flavor of Goat Milk and Its YogurtEmail this article to a colleague.
Save this article to My Clippings.
Discuss or comment on this article.
Abstract: Goat milk fat includes several branched chain fatty acids (BCFAs), like 4‐methyloctanoic acid, which when free, are responsible for goaty flavor. This flavor limits the market opportunities for goat milk. Prior research showed that cyclodextrins (CDs) can reduce goaty flavor, presumably by binding free fatty acids. This research extends that observation. In odor ranking trials in citrate buffer at pH 4.8, β‐CD concentrations between 0% and 0.35% were increasingly effective in reducing odor intensity due to 4‐methyloctanoic acid, but only when present in high molar excess. α‐CD was also effective, but...

Discuss or comment on this article.
Abstract: Edible coatings made of whey protein isolate (WPI), pea starch (PS), and their combinations with carnauba wax (CW) were prepared and characterized. WPI combined with CW formed stable emulsion while PS with CW formed unstable emulsion and both formulations produced non‐homogeneous films. Addition of PS to WPI: CW combination at the ratio of 1: 1: 1, respectively, resulted in stable emulsion and homogenous films. The emulsion PS: WPI: CW (1: 1: 2) was stable and formed a continuous film but had less homogenous droplets size distribution when compared to 1: 1: 1 film. Combined films had a reduced tensile streng...

Discuss or comment on this article.
Abstract: The thermal stability of L‐5‐methyltetrafolic acid (L‐5‐MTHF) was investigated in model/buffer systems and food systems. L‐5‐MTHF degradation followed first‐order reaction kinetics with relatively greater (P < 0.01) stability at pH 4 compared to pH 6.8 in the buffer systems. This was confirmed using cyclic voltammetry. The stability (for example, k‐values) of L‐5‐MTHF in an oxygen controlled environment improved (P < 0.001) proportionally when in the presence of increasing molar ratios of sodium ascorbate (NaAsc). The addition of NaAsc to L‐5‐MTHF after heat treatment was also eff...

Abstract: Pinolenic acid (PLA) concentrate in fatty acid ethyl ester (FAEE) was efficiently produced from pine nut oil via lipase‐catalyzed ethanolysis using a recirculating packed bed reactor (RPBR). The effects of reaction temperature, molar ratio, and residence time on the concentration of PLA were explored. Novozym 435 lipase from Candida antarctica showed less selectivity toward PLA esterified at the sn‐3 position when temperature was increased from 45 to 55 °C. For the trials of molar ratio between 1: 50 and 1: 100 (pine nut oil to ethanol), there were no significant differences in the yield of PLA. Residen...

Abstract
The present work presents a successful attempt to achieve an enhanced and more predictable fermentation process in Spanish-style green olive technology by selection and use of autochthonous starter cultures. During the first phase of this work, two Spanish-like fermentations of green table olives of cultivar (cv) "Nocellara del Belice", coming from irrigated and not irrigated fields, were monitored, in order to highlight the best agricultural conditions for drupe production and to isolate lactic acid bacteria strains with relevant technological properties. Among 88 identified isolates, one Lactobacillus pe...

Abstract
The Gram-negative bacterium Vibrio vulnificus is a common inhabitant of estuarine environments. Globally, V. vulnificus is a significant foodborne pathogen capable of causing necrotizing wound infections and primary septicemia, and is a leading cause of seafood-related mortality. Unfortunately, molecular methods for the detection and enumeration of pathogenic V. vulnificus are hampered by the genetically diverse nature of this pathogen, the range of different biotypes capable of infecting humans and aquatic animals, and the fact that V. vulnificus contains pathogenic as well as non-pathogenic variants. ...

Abstract
The effects of previous exposure to sub-lethal acidic and osmotic stresses on the survival of Listeria monocytogenes during exposure to gastro-intestinal (GI) tract simulation, was investigated. Six L. monocytogenes strains isolated from cheeses were selected and exposed to high salt concentrations or acidic conditions and their viability compared in quick and slow digestions. The results demonstrated that (i) all isolates were more sensitive to the exposure to acidic than to osmotic sub-lethal conditions (ii) significant differences (p < 0.05) between the two types of digestion were observed; in slo...

Abstract
Although sporulation environmental factors are known to impact on Bacillus spore heat resistance, they are not integrated into predictive models used to calculate the efficiency of heating processes. This work reports the influence of temperature and pH encountered during sporulation on heat resistance of Bacillus weihenstephanensis KBAB4 and Bacillus licheniformis AD978 spores. A decrease in heat resistance (δ) was observed for spores produced either at low temperature, at high temperature or at acidic pH. Sporulation temperature and pH maximizing the spore heat resistance were identified. Heat sensitivi...
