Abstract
Kualitas pangan segar dalam kemasan sulit diidentifikasi secara dini dan menimbulkan keraguan konsumen akan kesegaran produk yang dikemas. Oleh karena itu, diperlukan alternatif kemasan yang mampu menginformasikan kesegaran pangan secara real-time, salah satunya adalah smart packaging dalam bentuk film indikator. Penelitian ini bertujuan untuk mengembangkan film indikator berbasis tepung biji jali (Coix lacryma-jobi L.) dan ekstrak bunga pacar air (Impatiens balsamina), serta menyelidiki karakteristik dan kemampuannya dalam pemantauan kesegaran ikan kembung. Metode yang digunakan meliputi persiapan dan karakterisasi bahan baku menggunakan spektrofotometer UV-Vis, pembuatan film indikator dengan konsentrasi ekstrak bunga pacar air (EBPA) 1%, 2%, 3%, 4% dan 5% (b/b), penentuan film terbaik dalam memantau kesegaran ikan kembung, serta karakterisasi film menggunakan spektrofotometer FTIR, pengujian sifat fisik, mekanik, dan ketahanan film. Hasil penelitian menunjukkan bahwa EBPA berhasil di ekstrak dan mampu berubah warna pada pH 1-12, dengan kadar antosianin 1644,43 mg/L. Film indikator dengan konsentrasi EBPA 1%, 2%, 3%, 4%, dan 5% (b/b) berhasil dibuat. Film indikator EBPA 4% terpilih sebagai film terbaik yang mampu menginformasikan kesegaran ikan kembung selama penyimpanan melalui perubahan warna. Karakteristik film indikator EBPA menunjukkan nilai ketebalan, kekuatan tarik dan laju transmisi uap air yang lebih rendah, serta nilai kelarutan, swelling dan perpanjangan putus yang lebih tinggi dibanding film kontrol. Secara keseluruhan, tepung biji jali dan ekstrak bunga pacar air berhasil membentuk film indikator yang baik dan mampu memberikan informasi kesegaran ikan kembung. The quality of packaged fresh food is difficult to identify early and raises doubts among consumers about its freshness. Therefore, alternative packaging that can directly inform food freshness is needed, such as smart packaging in the form of indicator films. This study aims to develop an indicator film based on jali seed flour (Coix lacryma-jobi L.) and pacar air flower extract (Impatiens balsamina). Their characteristics and abilities in monitoring mackerel freshness were also investigated. The method used includes the preparation and characterization of raw material using a UV-Vis spectrophotometer, manufacture indicator films with concentrations of pacar air flower extract (EBPA) 1%, 2%, 3%, 4% and 5% (w/w), determining the best film in monitoring freshness of mackerel, characterizing the film using FTIR spectrophotometer, investigate the physical, mechanical, and resistance properties of the film. The results showed that EBPA was successfully extracted and was able to change color at pH 1-12, with anthocyanin levels of 1644.43 mg/L. Indicator films with EBPA concentrations of 1%, 2%, 3%, 4%, and 5% (w/w) were successfully produced. The 4% EBPA indicator film was selected as the best film which is able to inform mackerel freshness during storage through color changes. The characteristics of the EBPA indicator film showed lower thickness, tensile strength and water vapor transmission rate, followed by higher solubility, swelling and elongation at break values than the control film. Overall, jali seed flour and EBPA succeeded in forming a good indicator film and were able to provide information on the freshness of mackerel.
