“…The direct incorporation of TPE‐Ze into yogurt resulted in significantly higher acidity values compared to control and samples with TPE‐Ge during storage ( p < 0.05). Lactic acid was higher accumulated at the yogurt enriched with TPE‐loaded fibers because the accumulation of lactic acid was stimulated by TPE‐loaded fibers such as protein and carotenes (Radiati, Jaya, & Oktavia, ).…”

This study aimed the encapsulation of tomato peel extract (TPE) into zein and gelatin fibers via electrospinning to investigate their effect on the physicochemical and antioxidant properties of yogurt during storage at 4°C. The yogurt samples enriched with TPE had closer characteristics to control sample in terms of acidity, pH, syneresis, and viscosity parameters. The incorporation of TPE‐loaded fibers resulted in increasing of free radical scavenging activity of yogurt by 40%–60%. The yogurts enriched with TPE‐loaded fibers were redder, darker, and more yellow than control yogurt. Practical applications This study shows that the TPE‐loaded zein and gelatin fibers can serve as a functional additive in yoghurt, especially for improving its antioxidant and color properties. Therefore, it has the potential to fill the blank in the related literature and can provide a basis for further studies and it will be contributed to the utilization of nanofibers in food science and technology, particularly for encapsulation to protect and controlled release of active components. It will also contribute to the production of water‐soluble carotenoids by nanoencapsulation via electrospinning and use them in an aqueous food matrix. However, future toxicological studies are required to establish the potential adverse effects of nanotechnology on human health.

Goat milk kefir is a fermented milk product with kefir grain, as a probiotic agent and contains bioactive compounds. Kefir grains consist of bacteria and yeast. One of these yeasts are Saccharomyces cerevisiae, its role in the kefir system can be enhanced by restructure of kefir grain with increased Saccharomyces cerevisiae population. The objectives of this research were to analysis effect of the Saccharomyces cerevisiae concentration levels on kefir, as antibacterial against Escherichia coli, Salmonella typhi. Klebsiella pneumoniae, antioxidant activity, β-galactosidase synthesis. The research method was true experiment by Completely Randomized Design consist of 5 kind Saccharomyces cerevisiae concentration levels (S0: control; S1: 0.10%; S2: 0,25%; S3: 0.5% and S4: 1.0% v/w) of kefir grain. The results showed that kefir inhibited Escherichia coli, Salmonella typhi and Klebsiella pneumoniae, able to produce β-galactosidase and antioxidant activity. Kefir is relevant as food functional development.

Obesitas menjadi salah satu penyebab utama sindrom metabolik dislipidemia, yang dapat sebagai komorbid berbagai penyakit. Penggunaan obat-obatan untuk mengurangi obesitas memiliki akibat yang merugikan, oleh karena itu dikembangkan produk komplementer dari susu fermentasi sebagai strategi non-farmakologis untuk pengelolaan dislipidemia. Pemecahan masalah obesitas dapat dilakukan melalui pendekatan adipogenesis pada sel model adiposit 3T3-L1. Tujuan penelitian ini adalah menganalisis pemberian whey-KSK terhadap TG (Total Trigliserida), TC (Total Kolesterol) dan aktivitas PEPCK (Phosphoenol pyruvate Carboxykinase) sel adiposit 3T3-L1. Metode penelitian adalah percobaan pemberian dosis whey-KSK yang berbeda yaitu P1 (25mg/ml), P2 (50 mg/ml), P3 (75 mg/ml), P4 (100 mg/ml), dan kelompok KN (kontrol negatif) dan KP (kontrol positif) pada adiposit 3T3-L1, dengan empat kali ulangan. Hasil penelitian menunjukkan whey-KSK 25 – 100 µg/mL dapat menurunkan TG sebesar 35,39 – 55,32%, menurunkan TC sebesar 30,46-62,12%, menurunkan aktivitas PEPCK sebesar 27,10-82,52% dan menurunkan aktivitas spesifik PEPCK sebesar 33,06-63,34%. Kesimpulan whey-KSK dapat menghambat adipogenesis sel adiposit 3T3-L1 dan berpotensi sebagai antiobesitas.
