CONCLUSIONS: Crispiness is an extremely complex parameter to quantify being a function

of many artifact attributes. This investigation has excluded the inclusion of

number of peaks in order to simplify the equation employed, however, it should

be noted that the number of internal factors is an important consideration

whenevaluatingtheforce:deformationprolesformed.Morecomprehensive

equations should include the calculation of peaks per mm penetration as well

as the internal strength or bake characteristics of the product.

FACTORS: 1. Biscuit composition

2. Sample age

3. Atmospheric exposure

4. Positioning beneath probe (closeness to sample edges)

5. Surface characteristics

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

force:deformationproleoftheproduct.
