Background : Triphenylmethane dyes and metabolites are known or suspected mutagens and areprohibited in animals intended for human consumption. Despite toxicity, triphenylmethane dyes are used illegally as inexpensive treatments for fungal and parasite infections in aquatic animals. Objective: AOAC INTERNTIONAL Official Method ℠ 2012.25 for the LC-MS/MS determination of malachite green, crystal violet, brilliant green, and metabolites leucomalachite green and leucocrystal violet in seafood products was previously validated for finfish (trout, salmon, catfish, and tilapia) and shrimp, but had not been fully validated for other types of aquacultured products such as eel, molluscan shellfish, or frog or for processed seafoods...

Intestinal parasitic infection is one of the main causes of acute undernutrition in children. Oral consumption of oregano essential oil (OEO) can reduce intestinal parasitic infections, however, its addition to therapeutic and supplementary foods is hampered by its undesirable flavor. The objective of this study was to develop a functional lipid-based nutrient supplement (LNS) containing OEO, which is stable, acceptable and provides targeted intestinal delivery of bioactive. β-cyclodextrin (β-CyD) inclusion complexes of OEO (β-CyD-OEO), and carvacrol (β-CyD-CV) (1:1 molar) were prepared using slurry complexation (-20 °C) method and characterized based on encapsulation efficiency, moisture content, morphology, and 2-phase in vitro digestion stability...

Two-dimensional (2D) graphene oxide (GO) and molybdenum disulfide (MoS2) nanosheets (NSs) have been widely used as photothermal agents and as potential carriers of antitumor drugs. Their spatial thermal effects have been extensively explored for use at physiological and hyperthermic temperatures (37 to 46 °C). Furthermore, the modulation of the spatial thermal distributions with these NSs may have even more profound applications in the microstructural control of biomaterials at cryogenic temperatures (-196 to 37 °C)...

To enhance the curcumin delivery in a variety of food grade matrices namely spray dried ethanolic curcumin in fresh skim milk (Spray dried Cu-SM), a fresh mixture of ethanolic curcumin and skim milk (Fresh Cu-SM) a powder mixture of curcumin and skim milk powder (Powder Cu-SMP) and oil in water emulsion (Emulsion) were studied. The cellular uptake of curcumin from the respective matrices was studied on Caco-2 cell monolayers. Spray dried Cu-SM showed higher encapsulation efficiency compared to a corresponding Powder Cu-SMP and an oil-in-water emulsion (40% oil) bearing curcumin...

Sea buckthorn carotenoids extracted using CO2 supercritical fluids method were encapsulated within whey proteins isolate by transglutaminase (TG) mediated crosslinking reaction, coacervation and freeze drying. The encapsulation efficiency was 36.23 ± 1.58%, with β-carotene the major carotenoid present in the powder. The confocal analysis revealed that TG-ase mediated cross-linking reaction enhanced the complexes stability to such a manner that a double microencapsulation was performed. The powder showed an antioxidant activity of 2...

The consumption of pulses is associated with many health benefits. This study assessed post-prandial blood glucose response (PPBG) and the acceptability of food items containing green lentils. In human trials we: (i) defined processing methods (boiling, pureeing, freezing, roasting, spray-drying) that preserve the PPBG-lowering feature of lentils; (ii) used an appropriate processing method to prepare lentil food items, and compared the PPBG and relative glycemic responses (RGR) of lentil and control foods; and (iii) conducted consumer acceptability of the lentil foods...

Although the nutritional value of preschool menus largely determines the proper nutrition of attending children, their nutrient composition often does not meet the standards. The purpose of the study was to assess the nutritional value of menus served in preschools throughout Poland. We analyzed a sample of 10 daily menus and inventory reports reflecting foods and beverages served in 270 full-board government-sponsored preschools. Nutrient content was calculated per child per day, and compared with 70% of dietary reference intake (DRI) for children aged 1⁻3 and 4⁻6...

BACKGROUND: Saffron, the dried stigmas of Crocus sativus L., is a highly valued agricultural product that is used mainly as a food coloring and flavoring agent. Three main secondary metabolites of Crocus sativus including crocin, picrocrocin, and safranal are responsible for the color, the bitter taste and for the odor and aroma, respectively. As a component of traditional medicine, saffron has been utilized as a medicinal herb for treating various ailments including cramps, asthma, liver disease, menstruation disorders, pain, and in the pathogenesis of cancer...

Marine products are rich in not only micronutrients but also iodine content. However, the applications of iodine in marine products in the food industry have not been studied extensively. Therefore, in this study, a novel iodized salt was prepared through a simple method for iodine extraction from natural iodine-rich sources and spray drying. Laminaria ochroleuca (kombu), Porphyra umbilicalis (nori), Undaria pinnatifida (wakame), and Haliotis discus hannai (abalone) were selected as natural iodine-rich sources...

A rapid methodology was developed to simultaneously predict water content and activity values (aw ) of Moringa oleifera leaf powders (MOLP) using near infrared (NIR) signatures and experimental sorption isotherms. NIR spectra of MOLP samples (n = 181) were recorded. A Partial Least Square Regression model (PLS2) was obtained with low standard errors of prediction (SEP of 1.8% and 0.07 for water content and aw respectively). Experimental sorption isotherms obtained at 20, 30 and 40 °C showed similar profiles...

While the harmful effects of lactic acid bacterial bacteriophages in the dairy industry are well-established, the importance of Bacillus subtilis -infecting bacteriophages on soybean fermentation is poorly-studied. In this study, we isolated a B. subtilis -infecting bacteriophage BSP10 from Meju (a brick of dried fermented soybean) and further characterized it. This Myoviridae family bacteriophage exhibited a narrow host range against B. subtilis strains (17/52, 32.7%). The genome of bacteriophage BSP10 is 153,767 bp long with 236 open reading frames and 5 tRNAs...

BACKGROUND: Cow's milk is a core ingredient in foods for prevention and treatment of undernutrition in children. It promotes growth, but there is limited knowledge of which components in milk have growth-stimulating effects. OBJECTIVE: To discuss the growth-stimulating effects of milk in undernourished children with emphasis on protein, lactose, and minerals. METHODS: We reviewed literature on dairy and growth in undernourished children. RESULTS: Cow's milk has a specific stimulating effect on linear growth, even in well-nourished children, and it may stimulate weight gain and muscle accretion in wasted children...
