1. Impact of whey protein isolate coatings containing different antimicrobial agents on sliced bologna-type sausage during refrigerated storage
Abstract In this study, we aimed to determine the possibility of using the edible whey protein isolates coatings containing different antimicrobial agents on the bologna-type sausage slices and the inactivation effects of these coatings against Listeria innocua. For this purpose, edible whey protein isolates (WPI) coatings were prepared to contain essential

5. Natamycin and nisin to improve shelf life and minimize benzene generation in lemon soft drinks
Abstract Benzoic acids preservatives may be converted to benzene in soft drinks. The use of alternative antimicrobial compounds, specifically nisin and natamycin, would reduce benzene formation. Initially, doses of nisin and natamycin were tested against Lactobacillus plantarum lactic bacteria and Zygosaccharomyces bailii yeast. Using 167 UI/mL of nisin and

6. In vitro cytotoxicity of chemical preservatives on human fibroblast cells
ABSTRACT Preservatives are widely used substances that are commonly added to various cosmetic and pharmaceutical products to prevent or inhibit microbial growth. In this study, we compared the in vitro cytotoxicity of different types of currently used preservatives, including methylparaben, imidazolidinyl urea (IMU), and sodium benzoate, using the human newb

7. Effects of hurdle technology on Monascus ruber growth in green table olives: a response surface methodology approach
ABSTRACT An ascomycetes fungus was isolated from brine storage of green olives of the Arauco cultivar imported from Argentina and identified as Monascus ruber. The combined effects of different concentrations of sodium chloride (3.5-5.5%), sodium benzoate (0-0.1%), potassium sorbate (0-0.05%) and temperature (30-40 °C) were investigated on the growth of M.

8. Exploiting Cork as Biosorbent Extraction Phase for Solid-Phase Microextraction to Determine 3-(4-Methylbenzylidene)camphor and 2-Ethylhexyl 4-(Dimethylamino)benzoate in River Water by Gas Chromatography-Mass Spectrometry
In this study, a method for the determination of 3-(4-methylbenzylidene)camphor (4-MBC) and 2-ethylhexyl 4-(dimethylamino)benzoate (OD-PABA) in river water samples employing cork as the SPME (solid-phase microextraction) fiber was developed. The extraction parameters optimized were pH, ionic strength and extraction time and temperature. For the extraction st

9. Influence of nucleating agent on the crystallization kinetics and morphology of polypropylene
Abstract The influence of three nucleating agents from different generations on the crystallization behavior of propylene homopolymer was studied by differential scanning calorimetry (DSC) and atomic force microscopy (AFM). The amount of nucleating agent used varied between 1000 and 2200 ppm. The new generation nucleating agent, Hyperform® HPN-68L, accelera

11. Chemical modification of Aspergillus nigerβ-glucosidase and its catalytic properties
Aspergillus niger β-glucosidase was modified by covalent coupling to periodate activated polysaccharides (glycosylation). The conjugated enzyme to activated starch showed the highest specific activity (128.5 U/mg protein). Compared to the native enzyme, the conjugated form exhibited: a higher optimal reaction temperature, a lower Ea (activation energy), a h

12. Chemicals and lemon essential oil effect on Alicyclobacillus acidoterrestris viability
Alicyclobacillus acidoterrestris is considered to be one of the important target microorganisms in the quality control of acidic canned foods. There is an urgent need to develop a suitable method for inhibiting or controlling the germination and outgrowth of A.acidoterrestris in acidic drinks. The aim of this work was to evaluate the chemicals used in the le
