Abstract

Iodine deficiency disorders (IID) is still a major public health problem in several areas of the world. Especially in developing countries. The problem of iodine decrease or loss in iodized salt and food-stuff during processing is still the a controversial issue, among public, functionary, even the scientist. The stability of iodine is influenced by the food type, water content and cooking temperature. The objective of this research was to determine the effects of length of storage, relative humidity (RH) and temperature on the stability of iodized salt. Analysis of iodium was performed using Ion Pair High Perfomance Liquid Chromatography (HPCL). The rate of iodine decrease was influenced by salt origin, temperature, packaging material and RH during storage. The result of research showed that the percentage of iodate decrease in iodized salt packaged by high density polyethylene (HDPE) were 66.86% and 50.85% during storage for 14 days at temperature of 400C, RH 60% and 100%. Other result showed that the percentage of iodate decrease in iodized salt was 46.51% during storage for 28 days at temperature of 25.50C and RH 60-65%.

Abstract

Potassium iodate used as the source of iodine can be decomposed to become the other species i.e. iodide and iodine during processing and storage. The objective of this research was determination of the rate constant on the decrease of iodate content in iodized salt. The method was used to determine the temperature and the length of storage effects on iodate stability in iodized salt. The research was obtained the rate constant on the decrease of iodate content in iodized salt (K) 2.55 x 10-8 ppm day-1 and energy of activation (Ea) 12.002 kcal mol-1 K-1. Key words : Postassium iodate stability, iodized salt and the rate constant on the descrease of iodate

Abstract

Two species of iodine, i.e. iodide and iodate in commercial iodized salt were determined using ion pair HPLC. From 15 samples analysed, the iodide and iodate content ranged from 24,05 ± 2,51 to 70,25 ± 3,78 ppm and from 31,43 ± 8,10 to 87,59 ± 0,44 ppm, respectively. The method used was found satisfactory in terms of precission, accuracy, sensitivity and selectivity, therefore the method seem acceptable for the determination of iodide and iodate content in iodized salt samples. Key words : Iodine species, determination of iodine species content, and ion-pair HPLC

Abstract

ABSTRACTDetermination of Iodine Species Content in Commercials Iodized Salt and Foodstuffs During Cooking By Ion Pair HPLC MethodBackground: Iodine deficiency disorders (IDD) is still a major public health problem in several areas of the world, especially in developing countries. The stability of iodine will be influenced by food type, water content and temperature during cooking. The objectivse of the study was to determine iodine species in iodized salt and food. The benefit of the study was expected to answer the controversy problem about iodine losses in iodized salt and foodstuff.Methods: The study method used descriptive design (survey and intake samples, sample preparation and condition of appliance, making of standards solution, and analysis of iodine species), sampling method (purposif), and the analyse design (linear regression equation) , while analysis method was used by ion pair-HPLC.Results: The study revealed that iodine and iodate of iodized salt products fulfilled the requirement containing 30-80 mg kg-1. There different ways of adding iodized salt which were before, during and after cooking resulting highest reduction of iodine content in the first method (68,2%-61,9%) and the lowest in the last method (19,5%).Conclusion: Addition or used of iodized salt into foodstuffs should be after cooking or before serving.Key Words : iodized salt, foodstuffs, iodine species, iodine stability and HPLC-Ion PairABSTRAKLatar belakang: Kekurangan yodium masih menjadi masalah besar di beberapa negara di dunia, khususnya negara-negara berkembang. Kestabilan yodium akan dipengaruhi oleh jenis makanan, kandungan air dan suhu pemanasan pada saat pemasakan. Tujuan penelitian adalah menentukan kadar spesi yodium dalam garam beryodium yang beredar di pasar dan bahan makanan selama pemasakan. Manfaat Penelitian ini diharapkan dapat menjawab masalah perbedaan pendapat tentang hilangnya yodiumdalam garam beryodium dan bahan makanan.Metode: Metode penelitian yang digunakan adalah rancangan deskripsi (survei pasar dan pengambilan sampel, preparasi sampel dan pengkondisian alat, pembuatan larutan standar, dan pengujian kandungan spesi yodium dalam berbagai sampel), metode sampling (purposif), dan rancangan analisis (persaman regresi linier), sedangkan metode analisis yang digunakan adalah kromatografi cair kinerja tinggi-pasangan ion.Hasil: Hasil penelitian menunjukkan kadar spesi yodium (iodida dan iodat) dari 15 produk garam beryodium (dengan merk yang berbeda) yang beredar di pasar telah memenuhi persyaratan yaitu sebesar 30-80 mg kg-1. Tiga cara penambahan garam beryodium ke dalam sediaan makanan yaitu sebelum pemasakan, pada saat pemasakan dan siap saji, menunjukkan hasil persentase penurunan iodat tertinggi dengan cara penambahan sebelum pemasakan yakni sebesar 68,20% s/d 61,90% dan yang terkecil dengan carapenambahannya saat siap saji yaitu 19,5%.Simpulan: Cara penambahan atau penggunaan garam beryodium ke dalam makanan sebaiknya dilakukan setelah pemasakan atausiap saji.

Abstract

Snack bar adalah makanan ringan dengan bentuk batang yang terbuat dari berbagai bahan dasar seperti serealia dan kacang-kacangan. Konsumsi makanan fungsional saat ini mulai diminati karena mengandung zat yang bermanfaat bagi tubuh. Salah satu pemanfaatan produk snack bar yaitu menggunakan buah pisang. Pilot plant P2TTG LIPI Subang merupakan unit pengolahan buah pisang menjadi snack bar. Proses produksi snack bar membutuhkan penerapan sistem HACCP untuk meningkatkan kualitas dan keamanan produk. Oleh karena itu, kajian sistem HACCP ini penting untuk dilaksanakan. Berdasarkan rekomendasi Standar Nasional Indonesia, kajian identifikasi HACCP dilaksanakan dengan menggunakan panduan penyusunan rencana HACCP. Berdasarkan hasil kajian didapat bahwa CCP pada bahan adalah telur, puree pisang ambon, susu full cream bubuk, dan margarin. Sedangkan CCP pada proses pengolahan adalah pemanggangan I, pemanggangan II, dan pendinginan. Seluruh CCP ini perlu pengawasan optimal terutama pada: penanganan bahan baku, pengendalian kebersihan operator dan memastikan kecukupan panas serta waktu saat proses pemanggangan snack bar berbasis pisang. Efektifitas penerapan HACCP ini dapat diketahui melalui proses verifikasi. Penerapan HACCP diharapkan dapat meningkatkan kualitas dan keamanan produk snack bar berbasis pisang.HACCP, pisang,snack bar.
