Abstract
This study aims to enhance the bioactive property of cottage cheese by incorporating mulberry leaf extract (MLE) and applying probiotic fermentation. The MLE was produced via ultrasound-assisted water extraction (UW), pectinase-pretreated ultrasound-assisted water extraction (PUW) and cellulase-pretreated ultrasound-assisted water extraction. The MLE with the highest DPPH, FRAP, α-amylase inhibition (AI) and albumin denaturation inhibition (ADI) activities was selected to incorporate into the cheese. Lastly, the cheese was fermented with Lactobacillus plantarum TAR4. Results obtained reveal that UW and PUW produced MLE with the best bioactivities. Total phenolics, flavonoids, DPPH, FRAP, AI and ADI activities of the cottage cheeses were significantly enhanced with the fortification of MLE. Fermentation with L. plantarum TAR4 further enhanced the DPPH, FRAP, AI and ADI activities of the cheeses. Results of in-vitro digestion proved that the bioactivities exhibited by the cheeses did not diminished after digestion. Among the cheeses, fermented cheese fortified with MLE produced via UW (UW-LAB) showed the best bioactivity. After digestion, UW-LAB cheese exhibited 2.09 ± 0.12 mg g1 of FRAP, 74.77 ± 1.90% of DPPH, 64.91 ± 1.16% of AI and 38.83 ± 2.50% of ADI activities. This study recommends that combined MLE fortification with L. plantarum TAR4 fermentation was the best approach to improve nutrition value of cottage cheese.
