Antioxidant activity of goat's milk from three different locations in Malaysia

Abstract

Abstract. This study was conducted to evaluate the antioxidant activities of two types of goat milk obtained from three different farms in Malaysia named: Semenyih, Johor Baharu and Bander Baru Bangi . Milk from Jamnupari goat breed and a crossbred of Jamnupari and Saanen were investigated in terms of antioxidant capacity based on total phenol content (TPC), ferric reducing antioxidant power (FRAP), and 2,2-diphenyl-1-picrylhydrazyl (DPPH). Goat milk samples exhibited a significantly different antioxidant capacity (P>0.05) through all the samples. Jamnupari exhibited the highest capacity parity in TPC, FRAP, and DPPH assays (544.08 mg GA/100 g FW, 481.69 mg TE/100 g FW, and 64.77 %, respectively). By contrast, the milk sample obtained from the crossbred of Saanen and Jamnupari obtained from a UK farm exhibited the lowest values (354.14 mg GA/100 g FW, 313.58 mg TE/100 g FW, and 55.29 %, respectively). The samples obtained from the traditional farm in Bander Baru Bangi exhibited higher average values (523.80 mg GA/100 g FW, 439.33 mg TE/100 g FW, and 63.78%, respectively) than those from other sites.

Determination of Antioxidant Capacity and Free Radical Scavenging Activity of Milk from Native Cows (Bos Indicus ), Exotic Cows (Bos Taurus ), and Riverine Buffaloes (Bubalus Bubalis ) Across Different Lactation Stages

“…Also, correlation between milk fat content and antioxidant activity of milk was reported by Chen et al, [13]. Our results are consistent with the previous studies in human milk [14,15] and in goat milk [16] where they have reported that the total antioxidant capacity of milk had significantly higher values for colostrum as compared to mature and transitional milk. Colostrums milk could help in improving the antioxidant system to newborns.…”

A comparative study on the effects of boiling and ultrasonication on radical scavenging activity, casein particle size, and whiteness of milk

“…Several previous studies have reported that heat treatment reduced the radical scavenging activities of milk [ 18 ]. Casein has an effective role against lipid peroxidation and in radical scavenging activity [ 7 , 8 , 19 ]. Micellar casein is denatured during heating; therefore, the radical scavenging activity of heat-treated milk is reduced compared to non-treated milk.…”

Efecto de Morus alba en el contenido de flavonoides y perfil bromatológico de leche caprina

“…En sistemas de libre pastoreo las dietas ricas en plantas con altos contendidos de fenoles son incorporados a la leche (Cabiddu et al, 2019). Los compuestos fenólicos ayudan a proporcionar actividad antioxidante a los productos derivados de la leche y mejoran la salud animal (Alyaqoubi et al, 2014;Reyes-Becerril et al, 2021). Dentro de otras alternativas para adicionar fenoles se encuentra la incorporación de Acacia farmesiana, Chlorella pyrenoidos y Origanum vulgare spp.…”
