Antioxidant Activity, Biochemical Components and Sub-Chronic Toxicity of Different Brown Rice Kefir Powders

Antioxidant and Anti-Collagenase Activity of Sargassum Plagyophyllum Extract as an Anti-Wrinkle Cosmetic Ingredient

“…This result supported by previous studies who found that there are high correlations between concentrations of TPC and antioxidant activity. 17,26 Anti-Collagenase activity of S. plagyophyllum extract Activity of anti-collagenase was determined by with microplate readers at 340 nm. Collagenase assay only conducted to ethanol 25% S. plagyophyllum extract.…”

Characteristics of Thai Pigmented Rice Milk Kefirs with Potential as Antioxidant and Anti-Inflammatory Foods

“…22 In addition, our previous study found that Hawm Nil rice (dark purple rice) had the highest TPC when compared with other color rice and cow's milk. 6 Other research of pigment rice also reported that dark purple or black rice had high TPC compared to other color rice without fermentation. 4 …”

“…This result was also supported by our previous work concerning the antioxidant activity of rice. 6 However, the FRAP assay showed that rice milk formula IV (mixing of Khao Dawk Mali 105 rice, Hawm Nil rice and Red Hawm rice in a ratio of 1.5:1.5:3.0) had higher antioxidant activity than the other rice milk kefirs; however, this was not significantly different from that of cow's milk kefir. Free radicals have been implicated in the development of many disorders including cancer, neuro-degeneration and inflammation.…”

“…26 Although the TNF-α level in serum of the colitis rats that received PBS was highest, the colitis rats treated with rice and cow's milk kefirs also produced TNF-α at a lower level when compared to the control. Moreover, Chunchom et al (2017) 6 found that brown rice kefir powders had no sub-chronic toxicity in Wistar rats when the rats were given rice kefir Mean values within each column with different superscripts are significantly different, Duncan's test at p≤0.05. BS= blood sugar; BUN = blood urea nitrogen; CREA = creatinine; UA= uric acid TP = total serum protein; Alb = albumin; Glob = globulin.…”

“…12 Interestingly, it was found that the antioxidant activity of rice milk kefir was higher than that of cow's milk kefir. 6,7 McCue and Shetty (2005) suggested that the effects of antioxidants were higher in kefir fed with milk from plant sources as a result of the phenolic compounds in plants. Studies on chemical constituents as well as the effects of Thai rice milk kefir are still limited.…”
