Abstract

Tartrazine is a yellow synthetic dye that is widely used as a coloring agent in food and beverage products. However, the safety of this chemical compound is still a concern due to potential health risks such as allergic reactions, hyperactive behavior in children, increased risk of cancer and other negative impacts. This research aim to introduces a new approach to reduce the concentration of tartrazine dye using cobalt and nickel doped TiO2 nanowires. Cobalt- and nickel-doped TiO2 nanowires were synthesized by a hydrothermal method, followed by thermal treatment at 270°C, and then used in a photocatalytic reactor using UV irradiation to facilitate the reduction of tartrazine concentration. Material characterization was carried out to determine the morphology and crystallinity of the photocatalyst which is effective in reducing the absorption of tartrazine solution. The photocatalytic degradation experiment demonstrates the ability of the synthesized material as a photocatalyst, effectively reducing the absorbance of tartrazine solution, a commonly used food coloring. This finding promises significant progress in the development of sustainable food safety strategies by offering a dye degradation method.

Abstract

This study objectives to obtain the concentration of phosphorylated butyrylated arenga starches (PBAS) at different concentrations in the manufacture of edible films based on the physicochemical, mechanical and sensory characteristics of the edible film produced. The research was conducted at the Agroindustry Laboratory, Faculty of Agriculture, Tadulako University, Palu. The study design used a completely randomized design (CRD) and a randomized block design (RBD). CRD was used to determine the effect of PBAS edible film at different concentrations on physicochemical characteristics including thickness, water holding capacity (WHC), oil holding capacity (OHC), water vapor transmission rate (WVTR), solubility and expandability, water content, pH test, and mechanical characteristics include tensile strength, elongation and Young's modulus. RBD was used to determine the effect of PBAS edible film at different concentrations on the sensory properties of edible film, namely color, texture, aroma and overall. The treatment used consisted of 8 levels, namely 2,0; 2,5; 3,0; 3,5; 4,0; 4,5; 50 and 5,5% were repeated 2 times to obtain 16 experimental units. The results showed that the optimal concentration of PBAS was 3,0%. Thickness, solubility, moisture content, WVTR, tensile strength, and elongation increased with increasing concentration of PBAS, while WHC, OHC, swelling power, pH, and modulus young's decreased with increasing concentration of PBAS. The sensory of edible film in the form of color, texture, aroma, and overall were included in the like category. The resulting edible film has good potential to be applied in food products.

Abstract

Tren gaya hidup sehat mendorong pengembangan minuman fungsional berbasis ubi jalar ungu karena praktis, bergizi, dan digemari masyarakat. Namun, tantangan utama terletak pada proses pengolahan, khususnya pemanasan. Antosianin sangat sensitif terhadap suhu tinggi, pH, oksidasi, dan cahaya, sehingga mudah terdegradasi selama pemrosesan. Selain itu, viabilitas bakteri asam laktat sebagai mikroba probiotik sangat bergantung pada suhu pemrosesan. Untuk perlu dilakukan kajian tentang pengaruh suhu pemanasan terhadap bioaktif, viabilitas bakteri asam laktat dan organoleptik minuman fungsional ubi jalar ungu agar diperoleh suhu pemrosesan yang optimal. Penelitian ini didesain menggunakan Rancangan Acak Lengkap dengan faktor suhu pemanasan yaitu 70oC; 80oC; 90oC; 100oC. Perlakuan diulang sebanyak 5 kali sehingga diperoleh 20 sampel percobaan yang diuji kadar antosianin, aktivitas antioksidan, total bakteri asam laktat dan tingkat kesukaan secara organoleptik (uji hedonik) menggunakan 20 orang panelis terlatih. Perlakuan pemanasan dengan berbagai suhu (70 – 100oC) terbukti berpengaruh signifikan terhadap bioaktif seperti kadar antosianin dan aktivitas antioksidan, viabilitas bakteri asam laktat, dan tingkat kesukaan minuman fungsional ubi jalar ungu, dimana penggunaan suhu 70oC masih dapat mempertahankan bioaktif dari produk minuman fungsional dengan kadar antosianin sebesar 81,72 mg/L dan aktivitas antioksidan (IC50) sebesar 11,61 µg/mL (aktivitas antioksidan sangat kuat). Untuk viabilitas BAL perlakuan suhu 70 – 100oC terbukti menurunkan jumlah BAL yang ada di dalam produk secara signifikan (<107 CFU/L) dengan total BAL berkisar 0,0407 – 6,06 x 104 CFU/L. Sementara tingkat kesukaan secara organoleptik diperoleh suhu 80oC mampu menghasilkan produk minuman fungsional yang paling disukai oleh panelis baik tekstur (4,5), rasa (4,55), aroma (3,65) dan warnanya (3,45).

Abstract

Virgin Coconut Oil (VCO) merupakan minyak kelapa murni yang diperoleh dari daging kelapa segar tanpa proses pemanasan tinggi maupun perlakuan kimia, sehingga memiliki kualitas lebih baik dibanding minyak kelapa konvensional. Salah satu metode yang berkembang dalam produksi VCO adalah fermentasi dengan starter bakteri asam laktat (BAL), yang berperan dalam memecah emulsi santan sehingga memisahkan minyak dari fase air dan protein. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi starter BAL yang berbeda terhadap kualitas VCO serta menentukan konsentrasi optimal yang menghasilkan mutu terbaik. Penelitian menggunakan Rancangan Acak Lengkap (RAL) satu faktor dengan lima perlakuan konsentrasi starter BAL, yaitu P0 = 0% (kontrol), P1 = 5%, P2 = 10%, P3 = 15%, dan P4 = 20%, masing-masing diulang tiga kali. Parameter mutu VCO yang dianalisis meliputi rendemen, kadar air, asam lemak bebas, bilangan peroksida, bilangan iodin, nilai absorbansi (kejernihan), dan total BAL. Hasil penelitian menunjukkan bahwa perbedaan konsentrasi starter BAL berpengaruh nyata terhadap seluruh parameter mutu VCO. Rendemen tertinggi diperoleh pada P1 dengan nilai 23,5%, sedangkan pada konsentrasi BAL yang lebih tinggi terjadi penurunan rendemen. Kadar air terendah juga ditemukan pada P1 (0,13%), mendekati standar SNI (0,2%), sementara kadar air meningkat signifikan pada perlakuan BAL lebih tinggi. Asam lemak bebas, bilangan peroksida, dan nilai absorbansi cenderung meningkat seiring dengan tingginya konsentrasi BAL, sedangkan bilangan iodin yang dihasilkan relatif rendah namun masih dalam kisaran standar mutu. Secara keseluruhan, perlakuan P1 (5% BAL) menghasilkan VCO dengan kualitas terbaik dan paling mendekati standar mutu nasional maupun internasional. Dengan demikian, penggunaan starter BAL pada konsentrasi moderat dapat meningkatkan kualitas VCO, sedangkan konsentrasi berlebihan justru menurunkan mutu minyak.

Abstract

Soy milk kefir offers a plant-based alternative to dairy probiotics. This study aimed to enhance both the chemical and functional characteristics of soy milk kefir by evaluating the effects of varying kefir grain starter doses and added Clitoria ternatea (telang) flower juice. A 3x4 factorial design was employed using three starter levels (40g, 50g, 60g per liter soy milk) and four telang juice concentrations (0ml, 10ml, 20ml, 30ml per liter). Key parameters analyzed post-fermentation included protein content (Kjeldahl), lactic acid (titration), pH, Water Holding Capacity (WHC, centrifugation), anthocyanin content (differential pH method), and Lactic Acid Bacteria (LAB) count (plate count). Results indicated significant (p<0.05) effects of both starter dose and telang juice concentration, and their interaction, on all measured characteristics. Specifically, the 40g starter + 30ml juice treatment yielded the highest protein (39.35%) and anthocyanin (18.42 mg/mL). The 50g starter + 20ml juice treatment showed the highest WHC (67.30%). The 60g starter + 30ml juice treatment produced the highest lactic acid (20.30%). Higher LAB counts were observed in several treatments including A0B0, A1B1, A2B2, and A2B3 compared to others. In conclusion, optimizing kefir grain dosage and adding telang flower juice significantly improves soy milk kefir's nutritional profile (protein) and functional attributes (anthocyanins, WHC, LAB), demonstrating its potential as an enhanced plant-based functional food.
