(2006-01)The aim of the present work was to evaluate the effect of thermal and anaerobic treatments on physiological and biochemical parameters in a variety of tomatoes (Lycopersicon esculentum Mill. cv. Colt 45). Treatments applied ... -
High hydrostatic pressure and soybean protein addition to beef patties: effects on the formation of mixed aggregates and technological parameters
(2020-08-27)The effect of replacing 20% of meat proteins with soy protein isolate (SPI) and high hydrostatic pressure (HHP, 300 MPa-5 min) on technological, color and texture parameters of beef patties was studied. Also, HHP-induced ... -
High hydrostatic pressure assisted enzymatic hydrolysis of whey proteins
(2016-12)Whey proteins, due to their high nutritional value, are generally hydrolyzed to reduce the allergenicity and used as ingredients in many special products, such as infant formulae, geriatric products, highly energetic ... -
High hydrostatic pressure improves protein solubility and dispersion stability of mineral-added soybean protein isolate
(2015-01)The influence of ion type, ion concentration and pH on the effect of high hydrostatic pressure (HHP) on solubility and dispersion stability of soybean protein isolate (SPI) was analyzed. Solubilizing effect of HHP was ... -
High hydrostatic pressure processing of beef patties: effects of pressure level and sodium tripolyphosphate and sodium chloride concentrations on thermal and aggregative properties of proteins
(2014-06)Beef patties added with sodium tripolyphosphate (STPP; 0, 0.25 or 0.5%) and/or NaCl (0, 1 or 2%) were treated at 200 or 300 MPa (5 min, 5 °C) or kept refrigerated (non-pressurized). In non-pressurized patties, NaCl-solubilized ... -
High hydrostatic pressure treatment improves physicochemical properties of calcium- and soybean protein-added peach juice
(Elsevier, 2018-11)Calcium- and soybean proteins-added peach beverages were prepared and subjected to high hydrostatic pressure (HHP, 600 MPa, 5 min) in order to evaluate their physicochemical properties (protein solubility, physical stability, ... -
