An environmentally friendly packaging material was produced from starch with the incorporation of citrus lemon peel ethanol extract. Gas chromatography-mass spectrometry of the citrus lemon extract revealed the presence of compounds such as fatty acid, terpenes, aromatic esters, aldehyde, and polyphenolics. Bioplastic films produced with different percentages of the citrus lemon ethanol extract are designated as film0%, film5%, film10%, film15%, and film20%. From the physico-tensile properties of the bioplastics, the density ranges from 0.12 to 0.20 g cm−3, thickness, 0.25 to 0.74 mm, moisture content, 12.00 to 14.86, water-solubility, 1.23 to 2.84%, opacity, 0.36 to 0.67% and, tensile strength, 9.94 to 25.60 MPa. The 2,2-diphenyl-2-picrylhydrazyl anti-oxidant radical activities of the biofilms range from 1.44 to 6.19% and total phenol content, 0.01 to 0.32%. Proximate analysis of the fish after packaging revealed a decrease in moisture content from 38.69% (\({\text{film}}_{{{{o\% }}}}\)) to 12.01% (\({\text{film}}_{{20{{\% }}}}\)) and an increase in fat (20.93%—\({\text{film}}_{{0{{\% }}}}\) to 24.92%—\({\text{film}}_{{20{{\% }}}}\)), and protein (30.19%—\({\text{film}}_{{0{{\% }}}}\) to 37.06%—\({\text{film}}_{{20{{\% }}}}\)). Biochemical results revealed closeness of the peroxide, saponification, and total volatile basic nitrogen values of the fresh Pp fish and packed fish with film20%. The fatty acid analysis results showed that bioplastic with the highest amount of added citrus lemon extract had the best result; lowest saturated fatty acid, highest unsaturated fatty acid, and polyunsaturated fatty. Thus, good active packaging films have been produced from this research using waste citrus peel ethanol extract additive.

柑橘皮提取物淀粉基生物塑料:提取物浓度对包装鱼和生物塑料特性的影响

掺入柑桔柠檬皮乙醇提取物的淀粉制成了环保包装材料。柑橘柠檬提取物的气相色谱-质谱分析表明存在化合物,例如脂肪酸,萜烯,芳族酯,醛和多酚。用不同百分比的柑桔柠檬乙醇提取物生产的生物塑料薄膜被指定为薄膜0%,薄膜5%,薄膜10%,薄膜15%和薄膜20%。根据生物塑料的物理拉伸性质,密度范围为0.12至0.20 g cm -3厚度0.25至0.74mm,水分12.00至14.86,水溶性1.23至2.84%,不透明性0.36至0.67%,拉伸强度9.94至25.60MPa。生物膜的2,2-二苯基-2-吡啶并肼基抗氧化剂自由基活性为1.44%至6.19%,总酚含量为0.01%至0.32%。包装后对鱼的近距离分析表明,水分含量从38.69%(\({\ text {film}} _ {{{{{oo%}}}} \)降低到12.01%(\({\ text {film}} _ {{20 {{\%}}}} \))和脂肪增加(20.93%— \({\ text {film}} _ {{0 {{\%}}}}} \ )到24.92%- \({\ text {film}} _ {{20 {{\%}}}} \))和蛋白质(30.19%- \({\ text {film}} _ {{0 { {\%}}}} \)到37.06%- \({\ text {film}} _ {{20 {{\%}}}} \\))。生化结果显示新鲜的Pp鱼和有20%薄膜的包装鱼的过氧化物,皂化作用和总挥发性碱性氮值接近。脂肪酸分析结果表明,添加柠檬柑桔提取物量最多的生物增塑剂效果最好。最低的饱和脂肪酸,最高的不饱和脂肪酸和多不饱和脂肪酸。因此,使用废柑橘皮乙醇提取物添加剂从这项研究中生产出了良好的活性包装膜。
