13. An evaluation of immunomagnetic separation-real-time PCR (IMS-RTiPCR) combined assay for rapid and specific detection of Escherichia coli O157:H7 in raw milk and ground beef
Abstract The aim of this study is to optimize a rapid and specific method for detection of E. coli O157:H7 (EHEC) from food samples with high background flora using an immunomagnetic separation-real-time polymerase chain reaction assay (IMS-RTiPCR). For this, EHEC cells were recovered from raw milk and ground meat samples that were artificially contaminated

14. Peach palm flour (Bactris gasipae KUNTH): potential application in the food industry
Abstract Peach palm flours prepared from the landraces microcarpa (MIF), mesocarpa (MEF), and macrocarpa (MAF) were assessed for their functional and morphological characteristics. The flours had moisture contents in accordance with the current legislation, considerable lipid (≥3.95%) and carbohydrate (≥66.68%) contents, and potential as an energy source

15. Impacts of food-based enrichment on behaviour and physiology of male greater rheas (Rhea Americana, Rheidae, Aves)
Abstract Distress can be defined as a biological response of an individual to long-term threats to its homeostasis and it should be avoided from an animal welfare perspective. High levels of stress hormones and the expression of abnormal behaviours are responses normally observed in distressed animals. Captive environments can provoke distress, especially wh

16. Development and characterization of active film with omega-3 as a proposal for enrichment of butter
Abstract Active food packaging aims to interact with food in order to improve nutritional, sensory, physicochemical or microbiological properties of the food products. The aim of this work was to development and characterization of active film with omega-3 and flavored with oregano essential oil for butter. It was produced three films: control (T1), active

18. Pasting and gel texture properties of starch-molasses combinations
Abstract Molasses replacement by sugar are used in new product formulations for enrichment quality of products in the food industry. The influence of addition of wheat and corn starches on grape and carob molasses at different concentrations in distilled water (from 0 to 30% w/w) and holding temperatures (90 to 98 °C), pasting and gel texture properties we

19. Evaluation of the Direct and Enrichment Iso 10272 Methods for the Detection of Campylobacter Spp. in Chicken Meat
ABSTRACT In 2006, the International Organization for Standardization (ISO) published two standard protocols for the detection and enumeration of Campylobacter spp. in foods: the ISO 10272-2(direct method) and the ISO 10272-1 (enrichment method). The aim of this study was to compare the efficiency of these two methods in the detection of Campylobacter spp. an

20. Separation, Concentration and Determination of Trace Thiamphenicol in Egg, Milk and Honey Using Polyoxyethylene Lauryl Ether-Salt Aqueous Two-Phase System Coupled with High Performance Liquid Chromatography
As a pretreatment technique to trace analysis, polyoxyethylene lauryl ether (POELE10)- salt aqueous two-phase extraction system (ATPES) is coupled with high performance liquid chromatography to analyse thiamphenicol (TAP) in egg, milk and honey. The analysis of the phase behaviors of the ATPES found that the extraction efficiency and enrichment factor of TAP

21. Molecular characterization of a Xylanase-producing fungus isolated from fouled soil
Xylanase (EC 3. 2. 1. 8), hydrolyzes xylo-oligosaccharides into D-xylose and required for complete hydrolysis of native cellulose and biomass conversion. It has broad range of applications in the pulp and paper, pharmaceutical and Agri-food industries. Fifty fungal species were isolated from the fouled soil around an oil refinery and screened for the product

23. A novel multiplex PCR for the simultaneous detection of Salmonella enterica and Shigella species
Salmonella enterica and Shigella species are commonly associated with food and water borne infections leading to gastrointestinal diseases. The present work was undertaken to develop a sensitive and reliable PCR based detection system for simultaneous detection of Salmonella enterica and Shigella at species level. For this the conserved regions of specific g

24. Evaluation of a multiplex selective enrichment broth SEL for simultaneous detection of injured Salmonella, Escherichia coli O157:H7 and Listeria monocytogenes
Although many rapid and high throughput molecular methods have been developed in the recent years for the multiplex detection of foodborne pathogens, the simultaneous recovery and enrichment of sublethally injured cells is still a problem that needs to be considered. Combined with previous established multiplex real-time PCR assay, the capability of simultan
