14. Characterization and application of Lippia alba (Mill) and Cymbopogon citratus D.C. Stapf. essential oils as natural sanitizers in coriander
Abstract Essential oils (EOs) are a promising alternative for food preservation and can be used instead of synthetic antimicrobial compounds such as sanitizers, as long as they are efficient and safe. In view of this possibility of use, Lippia alba (Mill) (LAEO) and Cymbopogon citratus D.C. Stapf. (CCEO) essential oils were evaluated as natural antimicrobial

18. Acute toxicity study of a polysaccharide based hydrogel from linseed for potential use in drug delivery system
ABSTRACT Linseed hydrogel (LSH) was evaluated by acute toxicity for its potential application in oral drug delivery design. White albino mice and rabbits were divided in four groups (I-IV) and different doses of LSH (1, 2 and 5 g/kg body weight) were given except to the control group (I) that was left untreated. Rabbits were monitored for eye irritation, acu

20. Liver metabolic changes induced by conjugated linoleic acid in calorie-restricted rats
ABSTRACT Objective Complexes like conjugated linoleic acid (CLA) reduce the percentage of body fat by increasing energy expenditure, fat oxidation, or both. The aim of this study was to verify if CLA is able to mimic caloric restriction (CR), and determine the effects of CLA on liver metabolic profile of young adult male Wistar rats.

21. Effect of black cumin oil (Nigella sativa L.) on fresh fish (Barbus grypus) fillets during storage at 2 ± 1 °C
Abstract It is important that the methods and materials used for to lengthen the shelf-life of food are simple, inexpensive and safe. For these reasons, herbal additives like cumin oil (Nigella sativa L.) have been preferred recently. Thus, the present study focuses on the influence of black cumin oil on chemical, microbiological and sensory quality of fish

22. SUSTENTABILIDADE NO USO DO FÓSFORO: UMA QUESTÃO DE SEGURANÇA HÍDRICA E ALIMENTAR
The phosphorus used as fertilizer in agriculture is extracted from phosphate rocks, which after extraction reacts with sulfuric acid, releasing phosphoric acid, a raw material for the fertilizer industry. Studies point to a possible depletion of world reserves of phosphate rock in the next 50-100 years. A phosphorus scarcity is closely linked to global food

23. Occurrence of non-O157 Shiga toxin-encoding Escherichia coli in artisanal mozzarella cheese in Brazil: risk factor associated with food workers
Abstract Mozzarella cheese is considered a safe food due to the high temperature treatment used in the traditional process of stretching into hot water; however, a post-process contamination during the cheese manufacture or during the processing (before distribution) could occur. This study investigated the occurrence of Shiga toxin-encoding Escherichia coli
