Abstract(s)
Physalis (Physalis peruviana L.), also known
as cape gooseberry or ground-cherry, plays an important
role in nutrition as an excellent base for dietetic products.
Highly valued for its unique flavour, texture and colour,
recent research has shown that physalis fruit is rich in
many beneficial compounds.
In this study, the diameter and mass of physalis fruits were
measured, which can be used to calculate other biometric
characteristics of the fruit, such as: surface area, volume
or density. Other physical properties were measured,
namely the colour coordinates, by means of a Chroma
meter, whilst the textural parameters firmness and elasticity
were measured with a texturometer.
The following values were calculated for the physalis
fruits analysed in the present work: 1.69 cm for average
diameter; 8.98 cm2 for surface area, 2.51 cm3 for volume;
2.77 g for mass was, and 1.10 g/cm3 for density. The colour
coordinates were 56.72 for lightness, 16.69 for redness,
and 58.11 for yellowness. Skin firmness and elasticity
were evaluated for texture attributes, and their average
values were 2.40 N and 2.94 mm, respectively. The results
of this work are in accordance
