Comparative study of ultrasound application versus mechanical agitation on pork belly brining for bacon production.

Pork belly brining is a time-consuming step of bacon production that needs to be studied and enhanced through suitable technologies. In this sense, this study aimed at evaluating the impact of ultrasound (US), mechanical agitation (AG), and static brine (SB) on the kinetics of water loss (WL), solids gain (SG), and salt content (SC) of pork belly during brining under different temperatures. Mathematical models were used to estimate mass transfer rates, equilibrium parameters, and thermodynamic properties.

Mass transfer modeling during wet salting of caiman meat (Caiman crocodilus yacare) at different brine temperatures.

Caiman meat is considered exotic and its consumption has significantly increased due to its nutritional quality. This study aimed to evaluate the kinetics of water content (WC) and salt content (SC) at different temperatures (1, 5, 10 and 15 °C) and to evaluate the use of mathematical models to predict the mass transfer kinetics until equilibrium conditions during the wet salting of caiman tail fillets. Moisture and chloride analyses were performed throughout the wet salting process.

Antioxidant effect of acerola fruit powder, rosemary and licorice extract in caiman meat nuggets containing mechanically separated caiman meat.

The aim of this work was to evaluate the antioxidant effect of acerola fruit powder, rosemary and licorice extract in caiman meat nuggets containing high amounts of mechanically separated caiman meat (MSCM) during 120 days of frozen storage. Five treatments were prepared: a control without antioxidant (CON), sodium erythorbate at 500 mg/kg (ERY), acerola fruit powder at 500 mg/kg (AFP), with licorice extract at 500 mg/kg (LIE) and rosemary extract at 500 mg/kg (ROE). The addition of natural antioxidants increased color, cohesiveness, and decreased TBARS values.

Determination of the rheological behavior and thermophysical properties of malbec grape juice concentrates (Vitis vinifera).

The rheological behavior and thermophysical properties (density, specific heat, and thermal conductivity) were experimentally determined as function of temperature (1-66 °C) and solid soluble content (13.6-45.0°Brix) for Malbec grape juice aiming at designing the unit operations involved in beverage industries.

Ultrasound-assisted acid hydrolysis of cassava (Manihot esculenta) bagasse: Kinetics, acoustic field and structural effects.

Improving the actual acid hydrolysis of cassava bagasse (CB) with the assistance of high-intensity ultrasound (US) was aimed in comparison with mechanical agitation (AG). The kinetics of reducing and total sugar release were mathematically modeled. The acoustic field characterization and apparent viscosity of the suspensions were correlated.

Impact of ultrasound and potassium chloride on the physicochemical and sensory properties in low sodium restructured cooked ham.

The objectives of this study were to evaluate the effects of power ultrasound (nominal intensity 600 W·cm for 10 min) and the addition of potassium chloride (KCl) on the physicochemical properties and sensorial acceptance of low sodium restructured cooked ham. Four treatments of low sodium restructured cooked ham (mean of 324.52 mg Na/100 g) were prepared: CT - Control Treatment; UsT - Ultrasound Treatment; KT - addition of 0.

Improving sensory acceptance and physicochemical properties by ultrasound application to restructured cooked ham with salt (NaCl) reduction.

The objective of this research was to study the effects of salt reduction and the application of ultrasound (nominal current of 600 W cm for 10 min) on the physicochemical properties, the microstructure and the sensory acceptance of restructured cooked ham. Four treatments with reduced salt including one with the application of ultrasound (1.5, 1.

Experimental study of physical and rheological properties of grape juice using different temperatures and concentrations. Part II: Merlot.

The effect of the temperature and concentration on rheological behavior of Merlot juice concentrates was assessed using a rheometer over a wide range of temperature (1-66°C) and concentrations (13.6-45.0Brix) at shear rates of 0.

Experimental study of physical and rheological properties of grape juice using different temperatures and concentrations. Part I: Cabernet Sauvignon.

The effect of the temperature and concentration on rheological behavior of Cabernet Sauvignon juice concentrates was assessed using a rheometer over a wide range of temperature (1-66°C) and concentrations (13.6-45.0Brix) at shear rates of 0.

Effect of ethanol, dry extract and reducing sugars on density and viscosity of Brazilian red wines.

Background: Density and viscosity are properties that exert great influence on the body of wines. The present work aimed to evaluate the influence of the alcoholic content, dry extract, and reducing sugar content on density and viscosity of commercial dry red wines at different temperatures. The rheological assays were carried out on a controlled stress rheometer, using concentric cylinder geometry at seven temperatures (2, 8, 14, 16, 18, 20 and 26 °C).
