“ Soymilk” is a beverage made from soybeans and has become an important factor in human nutrition, due to the absence of cholesterol and lactose . The composition of “soymike” is different from cow milk in many aspects, such as fatty acid profiles, fat, protein as well as phyto-oestrogens (isoflavones) . For the fatty acid profile, “soymike” was rich omega-3-fatty acids.In contrast, a high percentage of saturated and mono-unsaturate fatty acids were detected in cowmilk . The main result was that cow milk showed a higher fat content than “soymilk” . Regarding Protein content, it was analysed using the Kjeldahlmethod . While cow milk had a protein content of approximately 3.5%, “soymilk” contain around 4.8% protein . According to phyto-oestrogens, 40 mg/100 g were found in “soymilk” . Theisoflovone composite was characterized via a newly established ultra performance liquid chromatography (UPLC) method. Thus, “soymilk” has a significant content of phyto-oestrogens(isoflavone) that are inexistent in cowsmilk,and plays an important role in human nutrition by now. In conclusion, “soymilk” truned out to be a valuable food and may be regarded as an option in human nutrition, in particular in certain cases (e.g.,lactose intolerance) . However, taking into account recent literature, “soymilk” can definitively not be consider as an adequate substitute for cow milk, especially regarding nutritional needs for young children .
