This work was carried out to determine the physical and chemical properties of
goldenberry fruit (Physalis peruviana L.) grown in Lam Ha and Don Duong of Lam Dong
province in Viet Nam. The shelf-life and quality of fruits during storage time at ambient
temperature (28±2oC) were also analysed. The analysis results recorded that most of the
physical properties of the fruit grown in the two locations (Lam Ha and Don Duong of
Lam Dong province, Viet Nam) yielded no significant differences, except the volume,
density, hardness and colour of the fruit. The fruit grown in Lam Ha has a lighter colour
and yellow intensity (higher a* and C value) than the ones grown in Don Duong, while the
fruits are grown in Don Duong are darker (lower L* and higher Ho). In addition to its
attractive properties in terms of colour, aroma and taste, they also contain moderate levels
of vitamins (C and A), antioxidants (polyphenols), minerals (especially high content of
phosphorus) and fibre. Fruit grown in Don Duong had a higher sweetness than those
grown in Lam Ha (the ratio of sugar and acid was 2.7 times more). The concentration of
bioactive compounds in the goldenberry fruits grown in Lam Ha and Don Duong were
almost similar. The shelf-life of goldenberries up to 20 to 22 days at the ambient
temperature of about 28±2oC and 75-80% RH but the quality and sensory characteristics
of goldenberry raw materials were declined.
