Abstract

Tomato (Lycopersicon esculentum Mill) is classified as one of fruity vegetables which could grow both sub-tropical region and tropical region. Tomato fruits are naturally prone to damage during the postharvest period. Extending the shelf-life of the fruits could be done by using edible natural coating. Beeswax is one of the natural edible materials that could be applied for fruit coating which is safe to be consumed. Anaerobic stress given to the fruits aimed to create suitable anaerobic volatiles to reduce the deterioration rate during the postharvest period; therefore, prolong the shelf-life. In anaerobic condition, ethanol (ethyl alcohol) and acetaldehyde are volatile compounds which are naturally produced from fruits and vegetables. This research was aim to investigate the effect of two different factors of treatments, namely the length of time of anaerobic stresses and different concentration of beeswax emulsion (o/w), as a coating material, on the quality and storage life of tomato fruits.The result showed that the effect of the both factors of treatments were significantly interacted on the deterioration of quality and storage life of tomato fruits. The length of anaerobic stress of 36 hrs combining with different concentration (1.5 and 3.0%) of beeswax emulsion as a coating material slowed the deterioration of quality and increased the storage life of tomato fruits. However, if the length of stress of 72 hrs combined with concentration of beeswax emulsion of 3%, the intensity of fruit damage increased.

Abstract

The aim of this study is to know the effect of ethanol vapor with different consentration and different concentration of beeswax emulsion, as a coating material that can preserve the quality and shelf life of salak Gulapasir. This research used a factorial randomized block design with two factors which are ethanol vapor treatment with 3 levels of concentrations (0%, 10% and 20%) and variety concentration of beeswax emulsion (0%, 1%, 2%, and 3%). Salak Gulapasir as control were prepared without treatment of ethanol vapor and beeswax emulsion, as a coating material. The experiment were devided into three groups. The observation is perfomed every five days until fifteenth day. The observed parameter of this research were weight loss, hardness, intensity of damage, total dissolved solids, total titrated acids, color difference and organoleptic test. The result of variance analysis showed that the interaction between ethanol vapor and beewax coating significantly affect the weight loss, hardness, intensity of damage, color difference, and organoleptic test. Whereas no significantly affect on total dissolved solids and total titrated acids. The combination of ethanol vapor of 20% (diluted in the water) and 1% concentration of beeswax emulsion as a coating material with the resulting characteristic weighted mean value of 21.04%, hardness 37.34 N, intensity of damage 6.79%, total dissolved solids 21, 04 0Brix, total acid 0.59%, color difference 26.14. Similarly, the organoleptic test has an average value of panelist for taste of 3.57, aroma 3.27, and color 3.51.
