V.2 A Comparison of the Textural Characteristics of Biscuits (Cookies)

PRODUCT: Biscuits

OBJECTIVE: To compare the textural characteristics of the two different types of biscuit

whileutilizingparametersgeneratedusingpenetrationtest.

BACKGROUND: The textural characteristics of hydroscopic foods (those which take up

water from the atmosphere) such as biscuits is of critical importance in the

assessment of their quality. The hardness of a sample is indicative of its

freshness, while the crispiness parameter evaluated within this investiga-

tion,characterizesitsinnercrumbstructureandbakecharacteristics.

The test may be employed as part of any quality control procedure, wheth-

er that is to evaluate staling of product life, bake characteristics through
