In this study, a smart biodegradable film based on wheat gluten modified with chlorophyll (WG/Ch) is presented. The effect of chlorophyll on the antioxidant activity and mechanical properties of WG/Ch film is studied. Scanning electron microscopy and Fourier‐transform infrared spectroscopy (FT‐IR) analyses are used to study the structure and chemical composition of gluten‐based films. The WG/Ch film is used in the packaging of sesame oil. The effect of WG/Ch film on increasing the shelf life and detecting expiration time of oil is studied. FT‐IR results show that weak interactions are created between gluten and chlorophyll. The antioxidant activity of the WG film is 60% and it increases to 85% by the addition of chlorophyll. The results show that with the increasing storage time of oil samples, oxidative indices are increased, but the WG/Ch film decreases the sesame oil oxidation significantly (almost in the all oxidative indices 50% decrease is observed). Practical Applications: The WG/Ch film is used in the packaging of sesame oil. The effect of WG/Ch film on the increasing of shelf life and detecting expiration time of oil is studied. By increasing storage time and oxidant, acidity, acid number, PA, and oil color change are increased, but the WG/Ch active film decreases the sesame oil oxidation significantly. Also, by examining the color properties of the active film, it is observed that with increasing storage time and oxidant percent, the color of the film is changed (from green to yellow), which can be used to estimate the oil expiration time. It should be mentioned that the film's color changes are visible to the naked eye.

The study consisted of reactor design used for transesterification process, effect of glycerol separation on transesterification reaction, determination of biodiesel quality, and mass balance analysis. The reactor was designed by integrating circulated pump/stirrer, static mixer, and sprayer that intensify the reaction in the outer tank reactor. The objective was to reduce the use of methanol in excess and to shorten the processing time. The results showed that the reactor that applied the glycerol separation was able to compensate for the decreased use of the reactant methanol from 6:1 to 5:1 molar ratio, and changed the mass balance in the product, including: (i) the increase of biodiesel production from 42.37% to 49.34%, and (ii) the reduction of methanol in excess from 42.37% to 32.89%. The results suggested that the efficiency of biodiesel production could be increased with the glycerol separation engineering. AbstrakDesain Reaktor Biodiesel dengan Pemisahan Gliserol untuk Meningkatkan Hasil Produksi Biodiesel. Penelitian ini terdiri dari desain reaktor yang digunakan untuk proses transesterifikasi, pengaruh pemisahan gliserol pada reaksi transesterifikasi, penentuan kualitas biodiesel, dan analisis neraca massa. Reaktor didesain dengan mengintegrasikan pompa/pengaduk, mixer statis, dan sprayer yang mengintensifikasi reaksi pada reaktor tangki luar. Tujuan penelitian ini adalah untuk menurunkan jumlah methanol yang berlebih dan mempercepat waktu pemrosesan. Hasil penelitian menunjukan bahwa reaktor yang menggunakan pemisahan gliserol dapat mengkompensasi penurunan penggunaan reaktan methanol dari 6:1 hingga 5:1 rasio molar, dan mengubah neraca massa pada produk yang antara lain: (i) peningkatan produksi biodiesel dari 42,37% hingga 49,34%, dan (ii) penurunan metano berlebih dari 42,37% hingga 32,89%. Berdasarkan hasil penelitian, efisiensi produksi biodiesel dapat ditingkatkan dengan rekayasa pemisahan gliserol.

“…In the case of stirring using blade agitator, the slow stirring could not give the optimal mixing thus the reaction would need long time and high energy consumption. By using blade agitator, conversion of methyl ester could reach the maximum conversion (>96.5%) in 1 h [5].…”
