In this study, the denatured whey protein paste (DWPP) was used to improve the texture characterizations of Gouda cheese. Five treatments of cheese were manufactured by adding 0, 1, 2, 3 and 4% of DWPP to cheese curd. Fortification of Gouda cheese with DWPP increased values of moisture, salt in moisture, water-soluble nitrogen/total nitrogen and non-protein nitrogen/total nitrogen whereas decreased values of density and free oil. The cheese contained DWPP was lighter and more yellowish compared to the control. The cheese samples contained 1 and 2% DWPP exhibited a significant increase in hardness, cohesiveness, springiness, gumminess and chewiness values while, the cheese samples that contained 3 and 4% DWPP exhibited a significant decrease. Adding DWPP to cheese lowered saturated fatty acids and raised unsaturated fatty acid (USFA) values which partially caused a lowering in cheese hardness at high levels of DWPP because of the low melting points of USFA. Based on these results, supplementation of Gouda cheese with 1 or 2% DWPP improved the texture properties.

Different solvents water, ethanol and ethanol/water (6:4 /), were compared in the extraction of pomegranate peels and seeds (PPS) in terms of recovery yields, antioxidant properties, and antimicrobial action against typical spoilage bacterial and fungal species. The best performing extract (ethanol/water (6:4 /) was shown to contain mostly ellagic acid and punicalagin as phenolic compounds (5% overall) and hydrolysable tannins (16% as ellagic acid equivalents) and was able to inhibit the growth of the acidophilic at a concentration as low as 1%. The preservation of the organoleptic profile of -inoculated apple juice with extract at 1% over 20 days was also observed thanks to the complete inhibition of bacterial growth, while the extract at 0.

The aim of this study was to analyze the influence of different packaging materials on the composition of the headspace (CO and O) of rennet cheeses packed in unit packaging under different modified atmosphere (MAP) conditions during a storage period of 90 days at 2 °C and 8 °C. The packaging materials comprised different combinations of BOPP-biaxially oriented polypropylene; PET-polyester; PE-polyethylene; PP-polypropylene; EVOH-ethylene-vinyl alcohol copolymer; PET-polyethylene terephthalate; and PA-polyamide. As the properties of the packaging material (foil) affect the gas conditions inside the packaging, it is important to study whether the modifications, i.

The effect of 90, 180 and 270 mEq/kg of the calcium sequestering salts (CSS) disodium phosphate (DSP), trisodium citrate (TSC) and sodium hexametaphosphate (SHMP) on the solubilisation of proteins and minerals and the rheological and textural properties of processed cheese (PC) prepared from Gouda cheese ripened for 30-150 d at 8°C was studied. The solubilisation of individual caseins and Ca and the maximum loss tangent during temperature sweeps of PC made from Gouda cheese increased, while hardness of PC decreased with ripening duration of the Gouda cheese. Levels of soluble Ca in PC increased with increasing concentration of TSC and SHMP, but decreased with increasing concentration of DSP.

Gouda cheese was produced from pasteurized milk and ripened for 30 weeks (PM-G). By application of gas chromatography/olfactometry and an aroma extract dilution analysis on the volatiles isolated by extraction/SAFE distillation, 25 odor-active compounds in the flavor dilution (FD) factor range from 16 to 4096 were identified. Butanoic acid, 2- and 3-methylbutanoic acid, and acetic acid showed the highest FD factors, and 2-phenylethanol, δ-decalactone, and δ-dodecalactone were most odor-active in the neutral-basic fraction.
