Aulia, Yukari Latifatul and Dr.Ir. Bambang Dwi Argo, DEA. and Dewi Maya Maharani, STP., M.Sc (2020) Aplikasi Pre-Treatment Ultrasonic-Ozone dan Edible Coating untuk Meningkatkan Kualitas Buah dan Sayur. Sarjana thesis, Universitas Brawijaya.
Abstract
Keamanan pangan di Indonesia masih belum memenuhi standar terkait penggunaan pestisida secara berlebihan oleh petani. Buah dan sayur mudah mengalami kerusakan mikrobiologis, fisik dan kimiawi setelah dipanen. Ozon memiliki potensi oksidasi yang tinggi untuk membunuh mikroba patogen. Teknologi ultrasonic-ozone efektif menurunkan residu pestisida. Tujuan dari penelitian ini untuk megetahui pengaruh pre- treatment ultrasonic-ozone dan edible coating pada buah dan sayur. Metode pelaksanaan yang dilakukan yaitu tahap desain, pegujian alat, uji alat dan uji buah dan sayur yang meliputi pengujian reduksi mikroba, identifikasi pestisida, tingkat kekerasan (tekstur),intensitas warna dan umur simpan. Hasil pengujian buah dan sayur meliputi reduksi mikroba sebesar 3 log cycle, pengujian tes kit strawberry, paprika dan sawi ultrasonic-ozone menunjukkan bebas pestisida. Green homogenity dan gray homogenity pada buah dan sayur hasil ultrasonic-ozone dan edible coating menghasilkan homogenitas warna dan tekstur yang dapat dipertahankan lebih lama dibandingkan dengan tanpa treatment. Tomat, strawberry, paprika dan sawi hasil treatment ultrasonic-ozone dan edible coating memiliki peningkatan umur simpan masing-masing 2,3 kali lipat; 2,5 kali lipat; 1,6 kali lipat; dan 1,6 kali lipat dibandingkan dengan sampel tanpa treatment.
English Abstract
Food security in Indonesia still does not comply any required standards due to an excessive use of pesticides. Fruits and vegetables would easily experience microbiological, physical, and chemical damage after being harvested. Ozone technology is considered as an effective technology to reduce pesticide residues and kill pathogens. The purpose of this study was to determine the effect of ultrasonic-ozone pretreatment and edible coating on fruits and vegetables. Several stages were conducted in the production and implementation of the equipment developed in this work such as the design stage, equipment instrumentation installation, equipment testing and sample testing which included testing microbial reduction testing, pesticide identification, level of hardness (texture), color intensity and shelf life. This equipment was able to reduce microbial damage up to 3 log cycle indicated from the test kit results of ultrasound-ozone and edible coating of strawberry, paprika, and mustard green showing pesticides free. This equipment was able to maintain the color and texture homogeneity of fruits and vegetables as well compared to untreated one. This work showed thatthere was an increase in shelf life of 2.3 times; 2.5 times; 1.6 times; and 1.6 times for Tomatoes, strawberries, paprikas, and mustard greens, respectively when it was treated with ultrasonic-ozone and edible coating compared to untreated ones.
