Fermented foods and probiotics: An approach to lactose intolerance.

The aim of this review was to present various topics related to lactose intolerance with special attention given to the role of fermented foods and probiotics in alleviating gastrointestinal symptoms. Lactose intolerance is a common digestive problem in which the human body is unable to digest lactose, known as milk sugar. Lactose intolerance can either be hereditary or a consequence of intestinal diseases.

Sulfamethazine contamination level and exposure assessment in domestic and imported poultry meats in Jordan.

Background And Aim: Sulfamethazine (SMZ) is an important and widely used antibiotic in poultry industry due to its high efficacy in fighting diseases and promoting growth. In addition, SMZ is a possible human carcinogen and has been found in many food types including poultry meat. Accordingly, this study aimed to survey the contamination level and estimated daily intake (EDI) of SMZ in domestic and imported poultry meat samples in Jordan.

Contamination level and exposure assessment to Aflatoxin M1 in Jordanian infant milk formulas.

Aflatoxin M1 (AFM1) is a principal hydroxylated-aflatoxin B1 (AFB1) metabolite, and has been classified as possible human carcinogen (group 2B). The aim of this study was to survey the contamination level, estimated daily intake (EDI) and tolerable daily intake % (TDI%) of AFM1 in Jordanian infant milk formulas. A total of 120 samples, 48 starter and 72 follow-on formula samples were collected and analyzed using ELISA technique.

The hypocholesterolemic and hormone modulation effects of isoflavones alone or co-fermented with probiotic bacteria in hypercholesterolemic rats model.

This study aimed to investigate the beneficial effect of isoflavones alone or probiotics-co-fermented isoflavones on serum and hepatic lipid profile, serum steroid (SHs) and thyroid hormones (THs) of hypercholesterolemic rats (N = 48). Animals were fed for 8 weeks with probiotics-co-fermented isoflavones or isoflavones alone, beside high-fat-high-cholesterol diet. Serum was analyzed for cholesterols, triglycerides (TG), SHs and THs.

Inactivation of stressed Escherichia coli O157:H7 cells on the surfaces of rocket salad leaves by chlorine and peroxyacetic acid.

Because Escherichia coli O157:H7 has been frequently associated with many foodborne outbreaks caused by consumption of leafy greens (lettuce, spinach, and celery), this study investigated the ability of deionized water, chlorine, and peroxyacetic acid to detach or inactivate stressed and unstressed cells of E. coli O157:H7 contaminating the surfaces of rocket salad leaves. E.

Sweet potatoes as a basic component in developing a medium for the cultivation of lactobacilli.

A sweet potato medium (SPM) was formed with extract from baked sweet potatoes supplemented with 0, 4, or 8 g/L of each nitrogen source (beef extract, yeast extract, and proteose peptone #3) to form SPM1, SPM2, and SPM3 respectively. Lactobacilli MRS was used as control medium. Ten Lactobacillus strains containing an average of 2.

Inhibition of Cronobacter sakazakii by heat labile bacteriocins produced by probiotic LAB isolated from healthy infants.

Cronobacter sakazakii is an opportunistic pathogen that can cause bacteremia, meningitis, and necrotizing enterocolitis, most often in neonates with case-fatality rates that may reach 80%. The antimicrobial activity of lactic acid bacteria against a wide range of foodborne pathogens is well-established in different types of food products. The objective of the current study was to investigate the antibacterial activity of Lactobacillus acidophilus and L.

Enhancement of alpha- and beta-galactosidase activity in Lactobacillus reuteri by different metal ions.

The hydrolysis of oligosaccharides and lactose is of great importance to the food industry. Normally, oligosaccharides like raffinose, stachyose, and verbascose which are rich in different plants like soy bean are considered indigestible by the human gut. Moreover, many humans suffer from lactose intolerance due to the absence of effective enzyme that can digest lactose.

Screening of antibacterial activity of lactic acid bacteria against different pathogens found in vacuum-packaged meat products.

The objective of this work was to screen the antibacterial activity of lactic acid bacteria (LAB) isolated from different sources against different pathogens found in ready-to-eat vacuum-packaged meat products (RTE-VPMP). LAB were isolated from human, RTE-VPMP, fermented vegetables, and dairy samples. These isolates were assessed for their antibacterial activity against Escherichia coli O157:H7, Salmonella spp.
