Regarding your specific question about whether the Milkotester can measure monosaccharides such as glucose or galactose, it's important to note that the standard analysis for lactose content typically involves enzymatic methods. The enzymatic method used in most milk analyzers, including the Milkotester, relies on the hydrolysis of lactose by the enzyme β-galactosidase, which specifically targets lactose and converts it into glucose and galactose. The resulting glucose is then measured using an enzymatic reaction.

Therefore, when you obtain the lactose content measurement using the Milkotester, it indirectly reflects the presence of glucose and galactose, which are the monosaccharides resulting from lactose hydrolysis. However, the Milkotester itself may not provide separate measurements for glucose and galactose individually.

If you specifically want to measure the individual concentrations of glucose and galactose in your lemongrass milk samples, you may need to employ additional analytical methods, such as high-performance liquid chromatography (HPLC) or specific enzymatic assays designed to measure these monosaccharides. These methods are more precise and can provide accurate quantification of glucose and galactose content separately.

Lemongrass does not naturally contain sugar. It is a herbaceous plant known for its strong lemony flavor and aroma. Lemongrass is primarily composed of water, essential oils, and various phytochemicals, but it does not contain significant amounts of sugar. However, it is worth noting that there may be some naturally occurring sugars in trace amounts, as is common in many plant-based foods, but they would not be present in significant quantities.
