A new method of firmness measurement of grape berries and other juicy fruits is described. The fruit is deformed between two parallel planes by a measured force. The measure for the firmness is the force which generates a given applanation area. Apparatus for measurement of the force and the area is described and measurements on grape berries are given. The measurements are fast, simple and accurate and the apparatus is inexpensive. The test is non-destructive and may be repeated several times on the same fruit.
Eine neue Methode zur Festigkeitsmessung von Traubenbeeren und anderen saftreichen Früchten
Eine neue MeBtechnik zur Festigkeitsprüfung von Weinbeeren und anderen saftreichen Früchten wird beschrieben. Die Frucht wird zwischen zwei parallelen Flächen durch eine gemessene Kraft deformiert. Das MaB für die Festigkeit ist die Kraft, durch welche eine bestimmte Abplattungsfläche erzeugt wird. Die Apparatur zur Messung der Kraft und Fläche wird beschrieben, und MeBergebnisse an Weinbeeren werden mitgeteilt. Die Messungen sind schnell, einfach und genau, und die Apparatur ist nicht kostspielig. Die Prüfung zerstört die Beere nicht und kann an derselben Frucht mehrmals wiederholt werden.
