Soy yogurt may have a slight beany
soy taste when made directly from freshly prepared soy milk, but this is less pronounced in shop-bought soy yogurt and in soy yogurt made from commercial soy milk. Soy yogurt is similar in protein content to dairy yogurt, lower in sugar, and higher in fat. If not fortified, soy yogurt does not contain
vitamin B12 or
vitamin D.
Plant-based milks have different structures and components than
dairy milk. Though they can be used to make many products similar to those made from dairy, there are differences in taste and texture. For example, "soy, almond, [and] coconut yogurts do not have the same delicate and smooth structure that conventional yogurts have." Since plant-based milks do not contain
lactose (the food of
Streptococcus thermophilus and
Lactobacillus bulgaricus), plant-based yogurts usually contain different bacterial strains than a dairy yogurt, such as
Lactobacillus casei,
Lactobacillus rhamnosus, and
Bifidobacterium bifidum. Plant-based yogurts also vary considerably in their nutrition and ingredients, and may contain gums, stabilizers, high-intensity sweeteners, and artificial colors. ==Regulation of word "yogurt"==
