Soy milk is produced from:

Soy milk is a plant-based beverage produced by soaking, grinding, and boiling soybeans in water. Unlike dairy milk which comes from mammals, soy milk is an aqueous extract of legumes and serves as a nutritional equivalent.

Think of soy milk as a 'tea' made from crushed soybeans; just as tea leaves release compounds into hot water, the soybean solids release their proteins and fats into the water to create a creamy white liquid.

The process involves the extraction of proteins and lipids from the soy matrix into the aqueous phase. Soybeans are soaked to soften them, then milled with water. The resulting slurry is heated to deactivate anti-nutritional factors like trypsin inhibitors and remove the 'beany' flavor (lipoxygenase activity), followed by filtration to remove the insoluble fiber (okara).
Soy milk is cholesterol-free and naturally lactose-free.
It is a rich source of plant-based protein and contains essential amino acids.
The solid byproduct remaining after filtration is called okara, which is high in fiber.
It requires fortification (e.g., Vitamin B12, Calcium) to match the nutritional profile of bovine milk.
Suitable for individuals with lactose intolerance.
Lower in saturated fat compared to whole cow milk.
Sustainable production with lower carbon footprint than dairy.
May contain antinutrients like phytic acid if not processed properly.
Common allergen for some individuals.
Often requires added fortification for nutritional parity.
Production of tofu and soy-based yogurts.
Culinary base for coffee lattes and vegan recipes.
Standard protein content in soy milk is approximately 3% to 3.5% by weight.
Options A, B, and C refer to animals that produce mammary-gland-derived milk, which contains lactose, a disaccharide sugar not found in plant-based milks.
D is correct тАФ Soy milk is derived exclusively from the legume Glycine max (soybean), whereas options A, B, and C are mammalian sources of dairy milk.
In competitive exams, remember that 'milk' from non-mammalian sources (like soy, almond, or oat) is technically an emulsion or suspension, not biological milk, which strictly implies mammalian mammary secretions.
