Abstract

Moringa plants contain various types of bioactive compounds in the form of phenolic compounds as antioxidants that are beneficial for health. One way of processing moringa leaves is to make moringa leaf flour by drying and blanching methods. The purpose of this study was to determine the effect of the best blanching time and temperature to produce moringa leaf flour. The blanching of moringa leaf flour was conducted with temperatures of 80 ± 2oC, 90 ± 2oC, and 100 ± 2oC and a duration of 5 minutes, 7 minutes, and 9 minutes. Based on the results, the variance of temperature and duration of blanching significantly affected the yield, total phenol content, beta-carotene content, and antioxidant activity (IC50) of moringa leaf flour. The results of the effectiveness index test showed that treatment at a temperature of 90 ± 2oC and a duration of 5 minutes produced the best moringa leaf flour with yield characteristics of 24.44 ± 0.09%, total phenol content 666.89 ± 4.57 mg/100 g, beta-carotene content 5763.86 ± 3.03 mg/100 g and antioxidant activity (IC50) 840.49 ± 31.29 ppm.

Abstract

Moringa leaves and tempeh contains high levels of glutamic acid, which has the potential to be developed as a flavor enhancer substitute for monosodium glutamate (MSG). This study aims to determine the sensory characteristics and the effect of the percentage of additions (1%, 2%, 3%, 4%, and 5%) of moringa and tempeh-based flavor enhancers on processed foods in the form of spinach clear soup. The design used in this study was a completely randomized design. The variables observed included the testing of sensory properties in the form of a threshold stimulation test, duo trio test, scoring test on taste parameters, and hedonic test on color, aroma, taste, and overall acceptance parameters. Data were analyzed by Analysis of Variance (ANOVA) and followed by Duncan's test. The results showed that flavor enhancers based on moringa leaves and tempeh had an absolute threshold of 0.17% and a difference threshold of 0.25%, and had a different level of umami flavor compared to MSG. The percentage of the addition of flavor enhancers has a very significant effect on the scoring of taste and the hedonics of color, taste, and overall acceptance, and has no significant effect on the aroma hedonics. The addition of flavor enhancer based on moringa leaves and tempeh with a percentage addition of 5% produces spinach clear soup with good sensory characteristics having a taste scoring value of 4.47 (very tasty), and color hedonics of 3.57 ( mildly like), aroma of 4.33 (mildly like), taste of 4.63 (like), and overall acceptance of 4.60 (like).

Abstract

Indonesia is the world's largest palm oil producer, contributing 59% of the total global production. The decreasing availability of fossil fuels contrasts with the increasing energy demand due to population growth. The development of bioethanol as an alternative energy source is expected to replace fossil fuels while contributing to environmental sustainability. Oil palm empty fruit bunches (OPEFB) are abundant industrial waste which is a potential raw material for bioethanol production. This study aims to analyze two different R5I3 cell treatments and fermentation time on bioethanol production from OPEFB and to determine the type of cell and fermentation time that produces the highest bioethanol content. The experiment was conducted using a Randomized Block Design with two factors: cell treatment types (free and immobilized cells) and fermentation time (24, 48, 72, and 96 hours). The results showed that cell treatment types significantly affected reducing sugar content, pH, total dissolved solids, and ethanol concentration. Fermentation time influenced reducing sugar content, total dissolved solids, and ethanol concentration but had no significant effect on pH. The treatment of immobilized R5I3 cells with a fermentation time of 72 hours produced bioethanol with the highest ethanol content of 1.02% (v/v).

Abstract

The high demand for healthier food is contributing to the innovation in pasta formulations, traditionally based on durum wheat semolina. In this context, recent reformulation has focused on the addition of plant-based and protein-rich ingredients, such as legumes, pseudocereals, fish protein, and dietary fiber, to enhance nutritional value and functional properties of pasta product. The reformulations cause an increase in protein, fiber content, amino acid, antioxidant capacity, glycemic control, and prebiotic activity. However, ingredient substitutions pose technological challenges, including changes in texture and high losses during the cooking process. Therefore, this study aims to optimize functional pasta product and address technological challenges by applying different processing methods such as fermentation, extrusion, and enzymatic treatments. The results showed that pasta fortification provided substantial nutritional benefits, although the impact on sensory characteristics posed a significant concern. This was because physicochemical properties of functional ingredients could alter the texture, color, and flavor of product, directly impacting consumer acceptance.

Abstract

Tujuan penelitian ini adalah untuk mengkaji efektivitas kombinasi antibakteri alami yaitu minyak sereh dan ekstrak bawang putih dengan NaCl, dalam menghambat pertumbuhan bakteri Escherichia coli dan Staphylococcus aureus. Penelitian ini menggunakan rancangan rancangan eksperimental laboratorium dengan perlakuan kombinasi 0%,1%, 2% dan 3% antara minyak sereh dan NaCl serta bawang putih dengan NaCl. Data dianalisis secara deskriptif dengan membandingkan nilai setiap perlakuan, kemudian ditafsirkan secara kualitatif untuk melihat tren efektivitas antibakteri terhadap masing-masing bakteri. Hasil analisis pH menunjukkan penurunan seiring peningkatan konsentrasi ekstrak. Nilai pH terendah dihasilkan pada konsentrasi 3% yaitu 4,8 untuk bawang putih–NaCl dan 5,7 untuk kombinasi minyak serehNaCl. Daya hambat tertinggi terhadap E. coli (1,60 mm) dan S. aureus (2,00 mm) diperoleh dari kombinasi bawang putihNaCl pada konsentrasi 3%, sedangkan kombinasi minyak sereh–NaCl menghasilkan zona hambat lebih kecil pada konsentrasi yang sama (E. coli 0,70 mm; S. aureus 0,92 mm). Secara keseluruhan, efektivitas antibakteri dari kedua kombinasi masih tergolong sangat lemah, namun menunjukkan potensi lebih besar terhadap S. aureus dibanding E. coli, yang diduga terkait dengan perbedaan struktur dinding sel bakteri.
