Abstract(s)
Physalis (Physalis Peruviana L), also known as Cape Gooseberry or Ground-cherry, plays an important role in nutrition being
an excellent base for dietetic products. Highly valued for its unique flavor, texture and color, recent research has shown that
physalis is rich in many beneficial compounds. In this study were evaluated some biometric characteristics of physalis, such
as the diameter and mass, and which allowed calculating others, like: surface area, volume or density. Other physical
properties were also evaluated, namely the color coordinates, by means of a Chroma metter, and textural parameters
evaluated by a texturometer: firmness and elasticity. The physalis analyzed in the present work have an average diameter
of 1.69 cm, a surface area of 8.98 cm2, a volume of 2.51 cm3, a mass of 2.77 g and a density of 1.10 g/cm3. The color
coordinates were found to be 56.72 for lightness, 16.69 for redness and 58.11 for yellowness. Regarding texture, two
attributes were evaluated, namely skin firmness and elasticity, and the average values found were 2.40 N and 2.94 mm,
respectively. The results of this work are in accordance with data from literature reported by other authors.
