Accurate species identification methods are needed to combat tuna fraud, improve tuna stock regulation, and mitigate health risks associated with mislabeled tuna products. The objective of this study was to conduct a market survey of raw and processed tuna products using a DNA mini-barcoding system based on the mitochondrial control region (CR). A total of 80 samples of raw, dried, and canned tuna products were collected at the retail level for CR mini-barcoding analysis. The samples underwent DNA extraction, polymerase chain reaction (PCR), and DNA sequencing of the 236-bp CR mini-barcode. The resulting sequences were searched against GenBank using the …

The microbiological profiles and responses of native microflora of endive were investigated using a model process line, to establish where a defined PFW should be optimally applied to retain or improve produce microbiological quality. The PFW processes were compared with tap water and ClO2. The antimicrobial efficacy of PFW was quantified by determining the reduction in microbial load, the microbial viability and vitality. Depending on the stage of application of PFW, up to 5 log10-cycles reduction was achieved, accompanied by a reduction of metabolic activity, but not necessarily with a decrease in metabolic vitality. Multiple application …

Superficial scald is a postharvest disorder of apples related to increased ethylene production in stored fruit which leads to α-farnesene accumulation and oxidation. Ionizing irradiation inhibits ethylene production and has been shown to reduce superficial scald, but this phenomenon has not been explored at the molecular level. The goal of this study was to determine the effect of irradiation on gene expression of enzymes related to ethylene and α-farnesene in ‘Granny Smith’ apples. Irradiation at 310 Gy controlled scald severity and incidence and inhibited the rise in AFS1 expression up to 90 d of cold storage followed by 7 d …

Immunoglobulin G (IgG) against food proteins has become the subject of much discussion with regards to its role in adverse food reactions. An estimated 20% of the population suffers from some type of food intolerance. Food sensitivity can present with a vast range of symptoms and severities. Diet can have a substantial impact on the wellbeing of individuals with diseases of the gastrointestinal tract, such as Crohn’s disease or ulcerative colitis. Incidentally, these diseases have been associated with elevated levels of food-specific IgG as well an increased likelihood of food sensitivity. The presence of food-specific IgG and food sensitivity in …
