Abstract

The extract which is still in liquid form, has several weaknesses, such as unstable in enviroment changes, low flexibility uses and trouble in material handling and transportation.  For these reasons, nanoencapsulation technique using β-siklodextrin as matrix agent is an alternative way. The aims of this research were characterization of total phenols, antioxidant activity of nanoencapsulation and the stability of the extract as well as nanocapsules against the changes of pHs, temperatures and boiling times.  Nanocapsules of roselle extract was containing phenol 4,53 + 0,26 mg/g, anthocyanin 2,99 + 0,18 mg/g, vitamin C 2,77 + 0,04 mg/g and water moisturizer 5,16 + 0,03%, antioxidant activity 49%.  Nanocapsules more resistence against the enviroment changes than the extract itself.  The stability test against the enviroment changes, the nanocapsules form more stable than the extract.  Showed with the slope of linier regression of nanocapsules form for phenols and antioxidant activity, respectively were: 0,111; 1,307 lower than the extract : 2,825; 7,634.  Nanocapsules more resistence against temperature and boiling time than the extract itself.  The stability test against temperature and boiling time, the nanocapsules form more stable than the extract.  Showed with the slope of linier regression of nanocapsules for phenols and antioxidant activity respectively were: 1,3315; 0,3162 lower than the extract : 1,5864; 0,5389

Abstract

During the supply chain activities, Arumanis mango as climateric fruit experiences quality changes due to the respiration process after being harvested. To find out the quality changes of Arumanis during their supply chain activities, it is necessary to simulate supply chain storage during land, sea, and air shipments in the laboratory. This study aims to predict changes in the quality of Arumanis during supply chain activities to retail storage. The supply chain simulation was carried out in 3 scenarios based on the delivery destination and transportation, including refrigerator trucks, ships, and planes. The temperature of the rooms used in the simulation was 10-12°C as the storage temperature for refrigerator trucks, aircraft cargo, and distribution center storage. The temperature at 20-22°C was used as retail storage temperature. Meanwhile, temperature at 24-28°C was used as the storage temperature for ships. The shipping duration used is 2 and 4 days. The parameters observed in this study were the concentration of carbon dioxide and total soluble solids. The results showed that the reaction kinetics model of quality changes Arumanis mango in all suitable supply chain scenarios was ordo 0 reaction seen from the higher correlation coefficient (R2). The shelf life of arumanis mangoes in all supply chain scenarios reached 8 days of storage. The development of this kinetics model can help to predict the quality changes of Arumanis mangoes during supply chain storage from distribution center to retail.
