Fryer University of Birmingham. The percentage of the pH changewas calculated according to the ohmicl equation: Effect of pulsed-vacuum and ohmic heating on the osmodehydration kinetics, physical properties and microstructure of apples cv. Low-frequency dielectric changes in cellular food material from ohmic heating: Calenamiento Ohmico Articulo Juice Nutrition.

A holewith diameter of 1 cm was created on the surface of the cell toobserve the bubbles formation, insertion of thermocouple, andexit of vapor in the cell.

Influence of ohmic heating and vacuum impregnation on the osmotic dehydration kinetics and microstructure of pears cv. Also; they re-ported that the quality of pomegranate juice such asrheological properties, color, and total phenolic content de-pends on heating rate.

Sample preparation Pomegranates Punica granatum L. This is mainlydue to its ability to heat materials rapidly and uniformly lead-ing to a less aggressive thermal treatment. The cell constant of the ohmic heater was1.

Similar results are found tocorrespond well with those existing in the literature Assiryet al.

Accuracy The accuracy of ohmic system was compared and calibratedwith the standard conductivity. The juice was then extracted by pressing thesamples with manual press at a pressing pressure of Juice market in india Juice Nutrition. The heat transfer area was also small.

The energy loss calculations for the exper-imental data were performed by using the method inIcier andIlicali b. Diffusion mechanisms during the osmotic dehydration of Granny Smith apples subjected to a moderate electric field.

Electrical conductivity and pH change. Due to these reasons,the heat loss to the surroundings was very small and couldbe neglected without any loss in accuracy. The temperature dependency of the electrical conductivity li-quid products follows linear or quadratic relations, dependingon product type tested such as ohnico pulps Castro et al.
