Apple Firmness Testing by Magness-Taylor Penetration Method

Objective texture testing of fruit is especially helpful when trying to determine the ripeness or freshness.  Information like this makes it simpler for growers to decide the correct moment to harvest in order to present the consumer with the most desirable product.

Then each sample was placed on the lower fulcrums of the fixture. The upper Magness-Taylor fixture moved and the system measured the force that was needed to break each sample - the firmness equating to freshness.

Candy (Peppermint) Hardness Testing by Cylinder Probe Penetration Method

The hardness of some candy is very important as it is an indication of its resistance to breakage during shipment. Most of these hard candies are consumed in a way that does not involve chewing.

Candy Break Force Testing by Cylinder Probe Penetration Method

Many candies are considered to be hard, yet they are consumed by chewing. This means there is fine line between too hard and too soft.

If the candy is said to be soft, it could break or have a texture that is undesirable to the consumer.

A product that is too hard could result in something like a broken tooth for the consumer. The producers want to avoid both of these situations.

Cheese (Block) Firmness Testing by Cylinder Probe Penetration Method

A simple test using a 6 mm probe used to determine the firmness of a piece of cheese in block form.

Test setup involved 2 varying types of cheese to compare. Samples were allowed equilibrate to ambient temperature (about 72 F°) prior to testing.

Cheese Slice Firmness Testing by Cylinder Probe Penetration Method

The firmness of cheese is often a primary quality indicator. This is especially true with a processed type of cheese where additional water is added to the product as a texture modifier.

Being able to objectively measure the firmness of the product allows the processors to have a better understanding on how changes in formulation can affect the texture. This test uses a 1 inch cylinder probe fixture to penetrate into a stack of 10 cheese slices.
