High-resolution thermal expansion measurements under helium-gas pressure
(2012-08-01)
We report on the realization of a capacitive dilatometer, designed for high-resolution measurements of length changes of a material for temperatures 1.4K ≤ T ≤ 300K and hydrostatic pressure P ≤ 250MPa. Helium ( 4He) is ...
High hydrostatic pressure assisted enzymatic hydrolysis of whey proteins
(Elsevier, 2016-12)
Whey proteins, dueto 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, high energy supplements ...
Rheological characterization of the thermal gelation of cowpea protein isolates: Effect of pretreatments with high hydrostatic pressure or calcium addition
(Elsevier Science, 2019-11)
Pretreatments with high hydrostatic pressure (HHP) or calcium addition were assessed for thermal gelation of two cowpea protein isolates (protein extraction at pHs 8.0, standard (A8) or 10.0, pH-shifting-modified (A10). ...
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 ...
Physicochemical and functional properties of cowpea protein isolates treated with temperature or high hydrostatic pressure
(Elsevier, 2016-01)
The effect of thermal (TT, 70 and 90 °C) and high hydrostatic pressure (HHPTs, 200, 400 and 600MPa) treatments on physicochemical and functional properties of cowpea protein isolates (CPIs) extracted at pH 8.0 (A8) and pH ...
Gelation of cowpea proteins by high hydrostatic pressure
(Elsevier, 2020-07)
The gelation of isolated cowpea protein induced by high hydrostatic pressure (HHP, 400 or 600 MPa) was studied in terms of rheological behavior, texture, color, water holding capacity (WHC), scanning electron microscopy ...
Osmotic dehydration under high hydrostatic pressure: Effects on antioxidant activity, total phenolics compounds, vitamin C and colour of strawberry (Fragaria vesca)
(Elsevier Science, 2013-03)
Simultaneous application of osmotic dehydration under high hydrostatic pressure conditions of strawberries was studied with the purpose of analyzing the effect of the combined process on the antioxidant capacity, phenolic ...
