Laboratory of Physical Properties of Fruits and Vegetables Opiekun laboratorium: dr Dariusz Wiącek Laboratory Supervisor: Dariusz Wiącek, PhD Tel. +48 81 744 50 61 Fax. +48 81 744 50 67 e-mail: d.wiacek@ipan.lublin.pl http://wfow.ipan.lublin.pl http://www.ipan.lublin.pl The laboratory concentrates on quality of fruits (apples, pears, strawberries, plums, currants, cherries, citrus fruits) and vegetables (carrots, leeks, celeries, beetroots, paprikas, tomatoes), their mechanical damage (contusions and squashes) during harvest, transport and storage, the influence of variety, temperature, storage time and ripeness on optical properties (colour, pigmentation intensity) of fruits and vegetables using colorimetric and spectrophotometric methods. Mechanical properties (firmness, damage resistance) are studied using compression and vibration tests, static and dynamic load tests, brittleness tests and fatigue tests in a wide range of temperature (cooling, freezing, heating). Research profile: • Development of physical methods for quality assessment of fruits and vegetables. • Mechanical properties of plant materials under static and dynamic loads. • Colouring of plant materials. Equipment INSTRON 6022 strength testing machine, manufacturer: Instron Ltd. (1987) • Strength testing of materials under static loads. • Axial testing: compression, stretching, bending, creeping and stress relaxation. • Determination of forces, deformation, energy and elastic modulus of examined materials. • Operating speed: 0-1000 mm/min, force range: up to 10 kN (0.1% of precision), operating space: up to 1635 mm (0.01 mm of precision). Examples of use: • Model research, strength assessment, analysis of flexibility, flowing and stress relaxation of plant, animal, dairy, construction and dental materials. • Comparative assessment of mechanical properties of crops, determination of strength parameters of structural components used in agriculture and agricultural and food processing machines and equipment. INSTRON 8872 strength testing machine, manufacturer: Instron Ltd. (2001) • Strength testing of materials under static and dynamic loads. • Axial testing: compression, stretching, breaking, creeping, flowing, fatigue and cyclic. • Force range: up to 25 kN, operating pitch: 50 mm; frequency: up to 50 Hz. Examples of use: • Model and fatigue research, strength assessment, analysis of flexibility, flowing and creeping of any materials under static and dynamic loads. • Comparative assessment of mechanical properties of apples, raspberries, and sprouts of flo wers and rape. Strength assessment of tennis string pulls. 23
