DISCUSSION: Force:deformationcurvesgeneratedindicatealinearrelationshipbetween

forces generated and depth of penetration. It was therefore recommended

that the 4mm mid penetration value is utilized to permit evaluation of a range

of chocolate types thus enabling comparison of a range of results.

PARAMETER All parameters are automatically calculated within the a test report once

COLLECTION they are selected on the test results tab. Thus calculate parameters for each

curve individually and record results.

PARAMETERS: HARDNESS Force necessary to attain a given deformation

WORK Internal strength of bonds within a product

ADHESIVENESS Work necessary to overcome attractive forces

between surface of the food and materials as the

probe retracts.

ADHESION Maximum negative load (stickiness)

RESULTS: PARAMETER UNIT 2mm 4mm 6mm

HARDNESS (g) 334 722 1159

WORK (m

) 3192.3 1278.6 23878.9

ADHESIVENESS (m

) -0.4 -4.1 -180

ADHESION (g) -18 -60 -15.1

NOTE:Adhesionforcesgivegreatestdifferentiation.

CONCLUSIONS: This empirical procedure generates key information related to chocolate

hardness and consistency, while additional information relating to adhesion

is also acquired. Adhesion forces were not considered paramount to the

investigation due to difculties in imitating oral mastication properties.
