Abstract:

This study aimed to produce the Ethylene Absorber Paper (EAP) from durian husk, that active packaging type. Durian husk was selected because it had holocellulose, which could produce package and paper. The durian husk was extracted for cellulose or fiber using sodium hydroxide and then lignin removed with hydrogen peroxide. Bleached and unbleached fiber were transformed to be paper by sheet former. Paper from unbleached fiber performed best properties with moisture content 7.99%, tear strength 435 mN, tensile strength 1.09 kN/m and burst strength 289 kPa and met the requirements of Thai industrial standard:170-2550 (55 grammage of Kraft Paper) except tensile strength. Afterward, unbleached fiber was prepared to EAP, which added with 3 different type of activated carbon viz. powder, granular and rod as ethylene absorber materials. EAP with powder activated carbon (PAC) was selected to prolong mango which showed lowest weight loss (10.55%) at 10 days of storage time at room temperature. After that, the suitable content of PAC added in EAP at 0, 5, 15, 25 and 35% (w/w) compared with commercial ethylene scavenger were demonstrated. Effectively absorb ethylene gas of all of EAP more than 95% since the early hours of absorbing. The results EAP with 5% PAC shown greatest extend postharvest life of mango for 15 days at room temperature storage and mango had lowest weight loss (28.59%) significantly different with other content and commercial ethylene absorber. Almost properties of all EAP met the requirements of Thai industrial standard:170-2550 except tensile strength but could be improved by adding dry strength agent. The results indicated that EAP from durian husk with 5% PAC had potential for development.
