The results showed that the maximum packaging speed of variable speed feeding could be increased by 35.6%, and the geneva mechanism with curved groove was suitable for higher speed packing.

Inhibitory Effect Of Eugenol On Providence Vermicola In Aquatic Products, Tursunay Turgun, Fan Wang, Long-Long Fu, Nurgul Rahman, Xiao-Li Liu

Food and Machinery

The inhibitory activity of eugenol was evaluated on Providence vermicola, which is a strain isolated from spoiled spicy crab product. The results showed that the minimum inhibitory concentration (MIC) was 0.25 mg/mL. Compared with the control group, the cells of P. vermicola treated with MIC eugenol were severely deformed, and wrinkles appeared. The cell wall of P. vermicola treated with eugenol was destroyed, leading to the leakage of intracellular substances and higher extracellular soluble protein content. The enzyme activities of malic acid dehydrogenase (MDH) and succinate dehydrogenase (SDH) were reduced by 33.01% and 19.81%, respectively. The normal metabolic system …

Mitigation Of Salmonella On Food Contact Surfaces By Using Organic Acid Mixtures Containing 2-Hydroxy-4-(Methylthio) Butanoic Acid (Hmtba), Aiswariya Deliephan, Janak Dhakal, Bhadriraju Subramanyam, Charles G. Aldrich

Department of Food Science and Technology: Faculty Publications

Contaminated surfaces can transmit pathogens to food in industrial and domestic food-handling environments. Exposure to pathogens on food contact surfaces may take place via the cross-contamination of pathogens during postprocessing activities. Formaldehyde-based commercial sanitizers in recent years are less commonly being used within food manufacturing facilities due to consumer perception and labeling concerns. There is interest in investigating clean-label, food-safe components for use on food contact surfaces to mitigate contamination from pathogenic bacteria, including Salmonella. In this study, the antimicrobial effects of two types of organic acid mixtures containing 2-hydroxy-4-(methylthio) butanoic acid (HMTBa), Activate DA™ and Activate US WD-MAX™, …

Nanoclays‑Containing Bio‑Based Packaging Materials: Properties, Applications, Safety, And Regulatory Issues, Kalpani Y. Perera, Maille Hopkins, Amit K. Jaiswal Dr, Swarna Jaiswal

Articles

Food packaging is an important concept for consumer satisfaction and the increased shelf life of food products. The introduction of novel food packaging materials has become an emerging trend in recent years, which could be mainly due to environmental pollution caused by plastic packaging and to reduce food waste. Recently, numerous studies have been carried out on nanoclays or nanolayered silicate to be used in packaging material development as reinforcing filler composites. Different types of nanoclays have been used as food packaging materials, while montmorillonite (MMT), halloysite, bentonite (BT), Cloisite, and organically modified nanoclays have become of great interest. The …

The Waxy Mutation In Sorghum And Other Cereal Grains Reshapes The Gut Microbiome By Reducing Levels Of Multiple Beneficial Species, Qinnan Yang, Mallory J. Suhr Van Haute, Scott E. Sattler, Devin J.

Waxy starches from cereal grains contain >90% amylopectin due to naturally occurring mutations that block amylose biosynthesis. Waxy starches have unique organoleptic characteristics (e.g. sticky rice) as well as desirable physicochemical properties for food processing. Using isogenic pairs of wild type sorghum lines and their waxy derivatives, we studied the effects of waxy starches in the whole grain context on the human gut microbiome. In vitro fermentations with human stool microbiomes show that beneficial taxonomic and metabolic signatures driven by grain from wild type parental lines are lost in fermentations of grain from the waxy derivatives and the beneficial signatures …

Markey Cancer Center Faculty Publications

Non-small cell lung cancer (NSCLC), the most common type of lung cancer, etiologically associates with tobacco smoking which mechanistically contributes to oxidative stress to facilitate the occurrence of mutations, oncogenic transformation and aberrantly activated signaling pathways. Our previous reports suggested an essential role of Sulfiredoxin (Srx) in promoting the development of lung cancer in humans, and was causally related to Peroxiredoxin IV (Prx4), the major downstream substrate and mediator of Srx-enhanced signaling. To further explore the role of the Srx-Prx4 axis in de novo lung tumorigenesis, we established Prx4−/− and Srx−/−/Prx4−/− mice in pure FVB/N background. Together with wild-type litter …
