The main aim of the present study is to extract and characterize cashew nut shell (CNS) starch and walnut shell cellulose (WNC) for development of cellulose reinforced starch films. Moreover, the extraction and characterization of pomegranate peel extract, for incorporation with CNS-WNC films, was investigated. CNS starch was examined to be a moderate amylose starch with 26.32 ± 0.43% amylose content. Thermal degradation temperature of CNS starch was found to be 310 °C. Walnut shell cellulose was found to have high crystallinity index of 72%, with two thermal degradation temperatures of 319 °C and 461 °C. 2% WN cellulose reinforced CNS starch films were examined to have good oxygen transfer rate, mechanical and physical properties. Thermal degradation temperature of CNS-WNC starch films were found to be at the range of 298–302 °C. Surface roughness of CNS-WNC starch films were found to be increasing with increase in concentration of cellulose in films. Hydroxymethylfurfurole, Benzene, 2-methoxy-1,3,4-trimethyl and 1,2,3-Propanetriol, 1-acetate were found to be major active compounds present in hydrophilic extracts of Punica granatum peels. 2% WN cellulose reinforced starch films infused with hydrophilic active compounds of pomegranate peel was examined to be having good active package properties.

本研究的主要目的是提取和表征腰果壳（CNS）淀粉和核桃壳纤维素（WNC），以开发纤维素增强淀粉薄膜。此外，还研究了与CNS-WNC膜结合使用的石榴皮提取物的提取和表征。经检测，CNS淀粉为中等直链淀粉，直链淀粉含量为26.32±0.43％。发现CNS淀粉的热降解温度为310℃。发现核桃壳纤维素具有72％的高结晶度，并且具有319℃和461℃的两个热降解温度。检验了2％WN纤维素增强的CNS淀粉膜具有良好的氧转移速率，机械和物理性能。发现CNS-WNC淀粉薄膜的热降解温度为298–302°C。发现CNS-WNC淀粉膜的表面粗糙度随着膜中纤维素浓度的增加而增加。发现羟甲基糠醛，苯，2-甲氧基-1,3,4-三甲基和1,2,3-丙三醇，1-乙酸盐是存在于甲壳素的亲水性提取物中的主要活性化合物。石榴皮。经检查，注入石榴皮亲水活性化合物的2％WN纤维素增强淀粉膜具有良好的活性包装性能。
