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.
