Apple Juice

Apple Juice Visc

USE
Apple juice is consumed as a beverage.


TEST EQUIPMENT

Instrument
Viscometer or Rheometer 
Spring Torque Range: LV 
Spindle: YULA-15E 

Accessories
Enhanced UL Adapter (ULA-EY), 
TC-502P Programmable, Refrigerated Bath 
Speed: 50, 75 and 100 rpm


TEST METHOD
The Enhanced UL Adapter may be used with various Brookfield Viscometers or Rheometers. In our example, we used a Brookfield LVDV-III+, with Rheocalc v3.1 software for automated instrument control and data acquisition. Our test temperatures of 4°C and 25°C were maintained by direct immersion of the Enhanced UL Adapter sample chamber into a TC-502P Programmable Refrigerated Bath. Representative data from the analyses are shown in Figure 1.

 

Apple Juice graph sm VA
Figure 1



Figure 1 graph shows relatively constant viscosities at 4°C (Blue Data: 2.5cP) and 25°C (Red Data: 1.4cP) over the speed range tested. This type of flow behavior is referred to as “Newtonian”. The graph also shows that the apple juice viscosity is higher at 4°C, than at 25°C. Increasing temperature typically decreases the viscosity of a given substance.
