Five maize hybrids were used in this research: two yellow and one white dent, sweet hybrid, popcorn. brine recipes with acetic acid examined, of which the addition potassium sorbate. The brines preservatives stable for 16 months without colour changes liquid corn cobs. pH ranged from 3.39 to 3.89. Canned ZP 366 611k sugar, sorbate metabisulfite marked as Number 5, showed best sensory characteri...

background: food borne pathogens are of the main concerns of food producers and consumers and escherichia coli and staphylococcus aureus create a lot of problems worldwide. the aim of this study was to evaluate antibacterial effects of monolaurin, sorbic acid and potassium sorbate on s. aureus and e. coli at different ph values and nacl concentrations. methods: micro-well dilution assay was use...

background: essential oils of medicinal plants such as chamomile are very complex natural mixtures which can contain compounds at quite different concentrations and some of their components have antioxidant and antimicrobial activities in foodstuff. objective: the antioxidant and antimicrobial effects of chamomile essential oil in cake preparation were evaluated during 75 days of storage. metho...

background and objectives:  high concentration of preservatives in food may result in gastrointestinal disturbances whereby some patients suffering from asthma, rhinitis, or urticaria. the aim of this study is the introduction and optimization a new method for simultaneous determination of four preservatives (sb, ps, mp, pp) in foodstuff by high performance liquid chromatography. materials and ...

Introduction: Olivier salad is one of the most common cold fast foods in our country that is nutritious because of its various ingredients, so it is susceptible to bacterial contamination. This study aimed to evaluate the chemical and microbial quality of Olivier salads that were sold in Mashhad groceries. Methods: In this study, 26 samples from two types of Ol...

The antibacterial and anti-inflammatory potential of natural, plant-derived compounds has been reported in many studies. Emerging evidence indicates that plant-derived essential oils and/or their major compounds may represent a plausible alternative treatment for acne, a prevalent skin disorder in both adolescent and adult populations. Therefore, the purpose of this study was to develop and sub...

The effects of storage methods on the shelf-life of dried beef product (Kilishi) were studied under ambient conditions for a period of forty-two days to compare traditional production and packaging system with a potassium sorbate (anti-fungal agent) treatment and modern packaging system. Changes in proximate composition and microbial counts for the control and treated samples were significant. ...

Eight salt-tolerant yeasts were isolated from contaminated pickled plums which were seasoned with honey and "Umami" seasoning. They were classified into four main groups according to random amplified polymorphic DNA analysis, and three of ten kinds of food additives tested inhibited their growth. The type strains of each group were identified as Zygosaccharomyces bisporus, Pichia subpeliculosa,...

The combined effects of water activity ([a(w)] 0.99 or 0.95), pH (4.5 or 3.5) and antimicrobial agent (potassium sorbate, sodium benzoate, sodium bisulfite, carvacrol, citral, eugenol, thymol, or vanillin) concentration (0, 100, 200 up to 1800 ppm) on the growth of Aspergillus flavus were evaluated in potato dextrose agar (PDA). Mold spore germination time and radial growth rates (RGR) were sig...
