Abstract

Pengaruh penambahan quercetin terhadap kadar histamin daging ikan tongkol (Euthynnus affi nis)selama penyimpanan pada suhu ruang dibahas melalui penelitian ini. Penambahan 0,5; 1,0; dan1,5% quercetin menyebabkan penurunan kadar histamin dan TPC daging ikan tongkol lumat padapenyimpanan jam ke-12, 24, dan 36. Kadar histamin mengalami penurunan yang signifi kan pada jamke-12 dari (74,613±0,513) mg/100 g menjadi (15,805±1,061) mg/100 g, (9,510±0,658) mg/100 g, dan(3,635±0,580) mg/100 g pada perlakuan penambahan 0,5; 1,0; dan 1,5% secara berurutan. Asam aminohistidin daging ikan tongkol dengan perlakuan penambahan quercetin mengalami penurunan yang lebihlambat selama penyimpanan dibandingkan perlakuan tanpa penambahan quercetin (kontrol).Kata kunci: histamin, histidin, ikan tongkol, quercetin, total plate countPENDAHULUANHistamin adalah senyawa amin biologisheterosiklik primer

Abstract

Spirulina platensis merupakan kelompok ganggang hijau biru berserabut yang mengandung senyawa fikobiliprotein. Fikosianin merupakan komplek pigmen-protein paling tinggi pada fikobiliprotein. Fikosianin memiliki nilai komersial yang paling dominan pada industri makanan, kosmetik maupun obat-obatan. Purifikasi fikosianin merupakan suatu proses peningkatan kemurnian dan salah satu cara untuk meningkatkan aktivitas spesifik fikosianin. Ocimum basilicum atau kemangi adalah tumbuhan yang mengandung azulene yang merupakan senyawa hidrokarbon aromatik yang berwarna biru. Tujuan penelitian ini adalah untuk menentukan pengaruh intervensi kemangi dan tingkat saturasi pengendapan amonium sulfat pada proses purifikasi fikosianin S. platensis terhadap indeks kemurnian, kandungan fikosianin, recovery, dan total protein. Metode purifikasi fikosianin yang digunakan adalah metode multistep yang terdiri dari ekstraksi S. platensis tanpa intervensi dan intervensi kemangi, pengendapan dengan amonium sulfat pada tingkat saturasi (0-20%), (20-50%), (50-70%), (70-90%), dan ultrafiltrasi (DF/UF). Hasil penelitian menunjukkan tingkat saturasi terbaik pada tahap purifikasi dengan pengendapan amonium sulfat untuk sampel tanpa intervensi sebesar 50% dan intervensi sebesar 70%. Fikosianin hasil intervensi kemangi memiliki nilai kemurnian dan kandungan fikosianin yang lebih tinggi dibandingkan sampel tanpa intervensi pada setiap tahapan purifikasi. Nilai kemurnian pada tahap purifikasi akhir sebesar 2,54 AU untuk sampel tanpa intervensi dan 2,57 AU untuk sampel intervensi kemangi. Perlakuan intervensi maupun tanpa intervensi daun kemangi pada S. platensis dapat menurunkan nilai recovery dan total protein pada setiap tahap purifikasi.

Abstract

Cuko pempek merupakan saus khas Palembang yang memiliki cita rasa asam, manis, dan pedas. Cuko pempek dapat dibuat dalam bentuk instan (bubuk) untuk menyediakan produk yang lebih tahan lama, praktis, dan mudah didistribusikan. Tujuan penelitian yaitu menentukan formulasi terbaik penambahan tinta cumi-cumi terhadap karakteristik kimia, fisik, dan hedonik cuko pempek instan. Cuko pempek instan dibuat dengan perlakuan penambahan tinta cumi-cumi konsentrasi 0, 3, 5, dan 7% (v/v). Proses pengeringan cuko pempek instan menggunakan metode foam-mat drying dengan putih telur 30% dan maltodekstrin 10% pada suhu 60℃ selama 4-8 jam. Parameter yang dianalisis meliputi kadar asam glutamat, air, protein, warna, kelarutan, dan uji hedonik. Hasil penelitian menunjukkan bahwa penambahan tinta cumi-cumi memiliki pengaruh nyata (p<0,05) terhadap karakteristik cuko pempek instan berdasarkan parameter kadar asam glutamat, air, protein, warna, dan uji hedonik pada parameter aroma dan rasa. Formulasi cuko pempek instan terbaik berdasarkan indeks efektivitas adalah penambahan tinta cumi-cumi 7%, yaitu kadar asam glutamat 3,55±0,01%, air 3,89±0,20%, protein 11,78±0,19% (bk), kecerahan (L*) 55,26±0,37, redness (a*) -3,43±0,09, yellowness (b*) 11,44±0,17, kelarutan 86,11±2,92%, dan rata-rata uji hedonik 3,10±0,29 dari skala 4,00.

Abstract

Spanish mackerel dried skin is commonly used in chips, crackers, and empek-empek products. However, its potential for transformation into value-added products such as collagen hydrolysate still needs to be explored. Processing this material using papain enzyme offers an efficient method to enhance its economic value, owing to its high yield and effectiveness. The aim of this study was to determine the optimum concentration of papain enzyme and soaking time for the hydrolysis of dried mackerel skin collagen based on the characteristics of dried mackerel skin collagen. This study applied a completely randomized design (CRD) with two factors: papain enzyme concentration (1% and 2%) and soaking time (12 and 24 h). The results indicated that the interaction between enzyme concentration and soaking time significantly affected key parameters, including hydrolysis degree, whiteness, protein content, viscosity, gel strength, melting point, solubility, and foaming ability, whereas yield, moisture, ash, fat, pH, and zeta potential were unaffected. Optimal conditions were achieved with 2% papain enzyme and 24-hour soaking time, resulting in a 2.30% yield, 35.62% hydrolysis degree, 77.73% white degree, 6.94% moisture, 1.44% ash, 95.35% protein, 2.33% lipid, 6,13cp viscosity, 46.64 gBloom gel strength, 14.67OC melting point, 5.83 pH, 2.47mV zeta potential, 82.00% solubility, and 31.67% foaming ability. These results highlight the significant potential of Spanish mackerel dried skin as a raw material for collagen hydrolysate production, supporting its application in developing high-value fishery by-products and promoting sustainable economic development.

Abstract

Phycocyanin, a blue pigment derived from the cyanobacterium Spirulina platensis, is typically purified through either single-step or multi-step processes. The purity of phycocyanin is crucial for its applications as a food colorant, in cosmetics, as a biomarker, and for analytical purposes. In this study, we report the purification of phycocyanin using a multi-step process involving extraction, ammonium sulfate precipitation, and diafiltration/ultrafiltration (DF/UF) with cycle times of 20, 30, and 40 minutes. The aim of this research to determine the effect of DF/UF time on flux, retention rates and purity on phycocyanin purification. The combination of DF/UF allowed the improving the purity of the phycocyanin in the retentate fraction. Sample that have been extracted and ammonium sulphate precipitation, were purified by ultrafiltration membrane using of hydrophilic polyethersulfone (PESH) membrane of 50 kDa MWCO. The DF/UF system was operated at 1.0 ± 0.1 Psi and at 24 ± 1oC. sample were collected during both DF/UF process in order to evaluated flux, retention rates and purity ratio of phycocyanin. The best DF/UF process were operate at 40 min per cycle, with a mean permeate flux 6.89 L/m2h and retention rate 96.99% was found to be optimal. This process resulted in phycocyanin with purity and concentration of 2.54 and 0.30 mg/mL, respectively. Hence, the DF/UF process were operated at 40 min per cycle potential for a biomarker application.
