V.3 Review of Solid Chocolate at Ambient Temperature
PRODUCT: Milk Chocolate (single chunk 27.25mm x 7.92mm)
OBJECTIVE: To determine the optimum penetration distance to detect hardness of solid
chocolate tablet through the employment of penetration forces.
BACKGROUND: The CT3 is restricted to maximum force generation in the region of 1kg thus
the relatively solid consistency of chocolate determined that a very small Ø
probewasutilizedatminimaltestspeed.Thispermittedaowofmolecules
within the sample and minimized the forces generated while maximizing the

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.
