Development of Two Imitative Methods of Spreadability Evaluation and Comparison with Penetration Tests

摘要

ABSTRACTTwo instrumental imitative methods simulating the manual operation of spreading were developed. Both methods make use of the Instron Machine: one is based on prototype cell (PSC) and the other involves the manual spreading of a known volume of product and recording of the force used. Various spreadable products were tested under different operating conditions. Results allow a clear differentiation among the tested products. Data obtained from the two methods show high correlations (significant at P<0.05) with data obtained from penetration methods that make use of probe, plunger, and cone. The newly developed methods show, under most test conditions, high correlations (significant at P<0.05) with sensory results.
