Chemical properties and shelf life of velvet apple germplasm

The study was undertaken to evaluate bio-chemical properties, shelf-life determination and expansion of ripe fruits four velvet apple germplasm. selected germplasm were local red variety, yellow PSTU Bilati gab-1 gab-2. Ripe collected from Germplasm Center, Patuakhali Science Technology University (PSTU) different locations district Bangladesh. Results expressed that maximum TSS (13.93%), vitamin-C (3.68 mg/100g), non-reducing sugar (5.15%) total (7.95%) recorded gab-2, the highest TA (1.30%) found in but pulp pH (7.50) ratio (11.11) variety whereas reducing (3.17%) variety. shelf life fruit varied 3.25 – 4.75 days where longest obtained gab-2 shortest But storability extended more than 27 when stored “Refrigerator” followed by “Non-perforated polybag (NPP)” (10 days), perforated (8 days) paper bag (6 days). firmness decreased gradually with reduction minimized storage condition hold refrigerator treatment NPP. Similarly, weight loss controlled NPP treatment. results experiments revealed provides superior chemical properties among ‘Refrigerator’ exhibited best performance other.
