Fruit and Vegetable Testing

 

 

 cylinder-probe-apple  kramer-cell-5-blade  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 and vegetables.
Multiple Pea Rig
Used to assess (in bulk) the
firmness of such non-uniform
samples as peas.
 multiple-chip-rig  three-point-bend-rig-banana  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,
celery.
 mini-kramer-ottawa-cell  circular-sample-support  multiple-puncture-probe-marmalade
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.
 acoustic-emission-video-playback  mini-kramer
Acoustic Envelope Detector
Allows the collection of acoustic data
during test procedures - of particular
interest when assessing crispness of
fruit and vegetables.
NEW: Mini Kramer Cell
Conforms to the specification for
AACCI Standard Method 56-36.01
for determining firmness of
cooked pulses.

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
  • Bruising Potential: apples
