Allergen Removal and Transfer Using Wiping and Cleaning Methods in Retail and Food Service Establishments.
Preventing the transfer of allergens from one food to another via food-contact surfaces in retail food environments is an important aspect of retail food safety. Existing recommendations for wiping and cleaning food-contact surfaces is mainly focused on preventing microorganisms such as bacteria and viruses from contaminating foods. The effectiveness of these wiping and cleaning recommendations […]
In vitro digestion effect on mineral bioaccessibility and antioxidant bioactive compounds of plant-based beverages.
Consumption of plant-based beverages (PBB) is a growing trend; and have been used as viable substitutes for dairy based products. To date, no study has comparatively analyzed mineral composition and effect of in vitro digestion on the bioaccessibility of different PBB. The aim of this research was to investigate the content of essential minerals (calcium […]
Impact of thermal pretreatment on crystallization of Thompson raisins.
After prolonged storage or during the shipment of raisins, a crystalline material may be developed on their surface, affecting the final acceptability of the product. The mild thermal pretreatment (50 °C for a period of 12 h and 48 h) was applied to dissolve any potential tiny crystals and nuclei already present in the raisins. […]
Thermal Resistance of Foodborne Pathogens and Enterococcus faecium NRRL B-2354 on Inoculated Pistachios.
Process control validations require knowledge of the resistance of the pathogen(s) of concern to the target treatment, and, in some cases, the relative resistance of surrogate organisms. Selected strains of Escherichia coli O157:H7 (five strains), Listeria monocytogenes (five strains), and Salmonella enterica (five strains) as well as Salmonella Enteritidis phage type (PT) 30 and nonpathogenic […]
Composition, Physicochemical and Sensorial Properties of Commercial Plant-Based Yogurts.
The aim of this study was to determine the key physicochemical, sensory and quality attributes of plant-based yogurts made from soy, coconut, cashew, almond and hemp, including a dairy benchmark yogurt. The soy, coconut and cashew-based yogurts showed textural parameters comparable to the dairy yogurt, with firmness values of 0.46, 0.44, 0.51 and 0.36 N, […]
A Lateral Flow Strip Based on a Truncated Aptamer-Complementary Strand for Detection of Type-B Aflatoxins in Nuts and Dried Figs.
Type-B aflatoxins (AFB1 and AFB2) frequently contaminate food, especially nuts and fried figs, and seriously threaten human health; hence, it is necessary for the newly rapid and sensitive detection methods to prevent the consumption of potentially contaminated food. Here, a lateral flow aptasensor for the detection of type-B aflatoxins was developed. It is based on the […]
Characterization of physico-chemical and bioactive properties of oils of some important almond cultivars by cold press and soxhlet extraction.
The oleic acid composition of almonds oils expressed by cold press varied from 73.56% in Cristomorto cultivar to 76.59% in Tuono while oleic acid in oils extracted by soxhlet method ranged from 71.86% in Cristomorto and 75.63% in Tuono cultivars. Also, oil from cold press extraction contained 19.51% and 21.86% linoleic acid for Ferragnes and […]
Impact of Drying Method on the Evaluation of Fatty Acids and Their Derived Volatile Compounds in ‘Thompson Seedless’ Raisins.
Air- and sun-dried raisins from Thompson Seedless (TS) grapes were analyzed under GC/MS to evaluate fatty acids (FAs) and their derived volatile compounds, coming from unsaturated fatty acids oxidation. A total of 16 FAs were identified in TS raisins, including 10 saturated fatty acids (SFAs) and 6 unsaturated fatty acids (USFAs). The contents of C18:0, […]
Influence of different cooking methods on the nutritional and potentially harmful components of peanuts.
This study investigated the comparative effects of boiling, roasting, deep-frying methods on the content of nutritional and potentially harmful components in peanuts. After cooking, the contents of total reducing sugar, sucrose, unsaturated fatty acids and almost all individual amino acids were reduced. Free methionine disappeared after heating processing, whereas fructose, starch, cis-palmitoleic acid and saturated […]
Species Composition, Temporal Abundance and Distribution of Insect Captures Inside and Outside Commercial Peanut Shelling Facilities.
Insect populations were studied within two commercial peanut shelling facilities located in the southeastern United States. Commercially available pheromone/kairomone-baited dome traps and pheromone-baited flight traps were deployed throughout processing and shipping portions of the shelling plants and serviced weekly over one year. Lasioderma serricorne, Tribolium castaneum, Typhaea stercorea, Carpophilus spp., Plodia interpunctella and Cadra cautella were the most common captures across […]
