Plant milk was produced from almond (Prunus amygdalu var. dulcis) seeds and home prepared soy milk served as control. The milk samples were subjected to proximate, mineral and sensory qualities evaluation using standard methods. A difference and preference test was carried out on milk samples for sensory evaluation. Almond milk sample had a characteristic white colour and milk yield was 82.5%. Significant differences (p<0.05) were observed in the proximate, mineral and mean sensory scores of milk samples. Almond milk had significantly higher ash and crude fibre contents. It also contained appreciable and significantly higher amounts of calcium (13.1mg/100ml), potassium (65.33mg/100ml), phosphorus (75.2mg/100ml), magnesium (42.05mg/100ml), iron (1.40mg/100ml) and zinc (4.58mg/100ml). Sensory evaluation of the milk samples showed significant differences between samples. Almond milk (1.90) was comparable to soymilk (2.10) in mouth feel  (p>0.05). However, almond milk was more preferred in terms of colour, flavor, taste and overall acceptability (p<0.05). Almond milk is nutrient dense with lower calories than soy and dairy milks. Noteworthy is its nutritional benefits of promoting cardiovascular health and reduction of trace mineral deficiencies especially iron and zinc.
