It depends ontemperature, applied voltage gradient, frequency, and concen-tration of electrolytes Icier and Ohico, c; Ye et al. Table 1 Some properties of the pomegranate juice used forohmic heating.
We are always happy to assist you. Production and hosting by Elsevier B.
Accuracy The accuracy lhmico 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 The percentage of the pH changewas calculated according to the following equation: Therefore, only the temperature in the cen-ter of the test cell was measured.
As the voltage gradient increased, time,system performance and pH decreased. Effect of pulsed-vacuum and ohmic heating on the osmodehydration kinetics, physical properties and microstructure of apples cv. The temperature dependency of the electrical conductivity li-quid products follows calentmaiento or quadratic relations, dependingon product type tested such as strawberry pulps Castro et al.

These values are similar to those observed in the literaturefor pomegranate juice byGhourchi and Barzegar ,Akbarpour et al. Please download to get full document. Conventionally heating is the most common method in theheating of foodstuffs. Moses 1 Estimated H-index: Suzanne KulshresthaSudhir K. GreenPower Manual Juice Nutrition.
Effect of ohmic heating and vacuum impregnation on the quality and microbial stability of osmotically dehydrated strawberries cv. Temperature uniformity was checkedduring previous heating experiments by measuring the temper-atures at different locations in the test cell.
The electrodes were thor-oughly rinsed using a brush and dematerialized with twice-dis-tilled water after each run. Technology Science Software Engineering.
The range of electrical conductivity during ohmic heating was0. In this study, theeffect of ohmic heating technique on electrical conductivity, heating rate, system performance andpH of pomegranate juice was investigated. Fryer University of Birmingham. The calibration results forthe accuracy of electrical conductivity of 0. Ohmic heating yields better products, clearly superior inquality than those processed by conventional heating Allaliet al.
Properties measurement Pomegranate juice density was determined by applying thepycnometric method. Similar results are found tocorrespond well with those existing in the literature Assiryet al.
Electrical conductivity and pH change. Art Design Architecture Photos. All materials on our website are shared by users. This is mainlydue to its ability to heat materials rapidly and uniformly lead-ing to a less aggressive thermal treatment.
Large particles in the juice were removed using a No. Effect of end point temperature innovative food science and emerging technologies [IF: For example,DeHalleux et al. Juice Nutrition Page 9. They werewashed in cold tap water, drained, and then manually cut intofour or six pieces.
