Any of the texture analyser range can be used for the product tests listed below.

A selection of special attachments and typical measurements are also shown which are commonly used in this application area. However, this does not show the complete range of attachments available for the testing of fruit and vegetable products. Test procedures include: compression, puncture/penetration, tension, fracture/bending, extrusion, cutting/shearing.

Typical measurements include:

  • Ripeness (normally associated with a loss of firmness): apples, peas, peaches, etc.

  • Firmness: can be used to e.g. determine optimum blanching times of processed fruit and vegetables, optimum shelf for maintenance of freshness of ready prepared salads, crudites etc.
  • Skin Rupture Force: ('Bioyield Point')
  • Crust Crispness: French Fries
  • Flexibility/Rigidity: vegetable batons
  • Consistency: fruit purees, fruit preparations
  • Stickiness: dried fruits

Small Cylinder probe

5-blade Kramer Shear cell

Multiple Pea Rig

Small Cylinder probe
Can be used to measure skin
rupture force and flesh firmness
of e.g. fruit.

5-blade Kramer Shear Cell
 Used to assess firmness (in bulk)
of fresh or processed fruit/

Multiple Pea Rig
Used to assess (in bulk) the
firmness of such non-uniform
samples as peas.

Multiple Chip Rig

Three Point Bend Rig

Fracture Wedges

Multiple Chip Rig
Used to assess the firmness
of French Fries.

Three Point Bend Rig
Can be used to assess fruit/
vegetable flexibility.

Fracture Wedges
Can be used to assess fracture/
'bite force' of e.g. carrot batons,

Mini Kramer Ottawa

Circular Sample Support

Mini Kramer/Ottawa cell
Particularly suited to reduce the
force of bulk shearing/compression 
of multi particle products or 
products of non-uniform texture.

Circular Sample Support
 Used to provide stable support
for circular samples for e.g.
penetration/compression tests with
the ability to retain any potential
fluid expressed during the test.

Multiple Puncture Probe
Particularly suited for the
penetration of multiple particulates
or non-uniform products to create
an averaging effect.

Application Studies are available for the testing of FRUIT & VEGETABLE products using the TA.XT2i, TA.XTplus, TA.XTExpress  or TA.HDplus texture analysers.

In addition, scientific papers have been published which reference the use of the TA.XT2i/TA.XTplus/TA.HDplus in the testing of FRUIT & VEGETABLE products.
