| Abstract | This study aimed to investigate the effects of different levels of Lactobacillus casei (L. casei) and Houttuynia cordata powder (HCP) on the chemical, physical properties and antioxidant activity of bio-fermented juice. The experiment was arranged in a 4 ? 3 factorial in a completely randomized design (CRD). Factor A consisted of four levels of L. casei at 0, 1, 10 and 20% (v/v), and Factor B comprised three levels of HCP at 10, 12.5 and 15% (w/v). The variables analyzed included total bacterial count, total phenolic content, total flavonoid content, quercitrin concentration, antioxidant activity (DPPH IC50 and ABTS IC50), moisture content, pH, total soluble solids, and total acidity. The results demonstrated that both the levels of L. casei and HCP significantly influenced the properties of bio-fermented Houttuynia cordata juice (p<0.05). Notably, the group supplemented with 1% L. casei and 15% HCP showed the highest total bacterial count at 8.667 ? 106 CFU/ml, along with a total phenolic content of 22.351 mg/g, total flavonoid content of 13.874 mg/g, and quercitrin content of 904.438 ?g/L. In addition, this group exhibited favorable antioxidant activities, with DPPH IC50 and ABTS IC50 values of 398.297 ?g/ml and 145.239 ?g/ml, respectively. These findings indicate a well-balanced combination of microbial population, bioactive compounds, and antioxidant capacity, highlighting the potential of using 1% L. casei with 15% HCP as an optimal formulation for producing bio-fermented Houttuynia cordata juice with desirable chemical, physical, and biological properties suitable for application in the livestock industry. |
