Horticulture Research Station wanted a precision penetrometer for hardness testing of different varieties of apple during plant breeding trials. Flexibility for future test configurations were also a requirement.
Textural properties and structure of different varieties of apple were identified as critical sensory characteristics. Changes in these properties needed to be monitored during plant breeding work.
Penetration testing expanding upon the traditional Magness-Taylor technique provided the research team with detailed information relating to apple firmness, bio-yield and skin rupture or toughness.
