Soymilk market has achieved tremendous progress in consumption and sales due to its inexpensiveness and soymilk protein content. However, due to the present global health crisis, there is a need to further devise means of enriching the quality of soymilk. This study aimed to evaluate the effects of sprouted soybeans and ginger on soymilk quality and sensory attributes. A developed dual -powered milk pasteurizer was used to produce the soymilk. Soybeans, a mixture of soybeans and sprouted soybeans, and sprouted soybeans were interacted with peeled ginger and whole ginger rhizome using Taguchi experimental design to produce nine soymilk samples. The proximate composition, calorific value, total phenolic content and phytic acid content of the soymilk samples were determined using standard procedures. The moisture content of the soymilk samples ranged from 80.85 to 83.78%, crude protein content (7.47 – 9.54%), ash content (0.72 – 1.27%), fibre content (0.24 – 0.73%), crude fat (0.24 – 5.44%), carbohydrate content (1.29 -6.82%) and calorific value (67.6 kcal/g – 91.58 kcal/g). The total phenolic content and phytic acid content ranged from 4.81 mg/l to 11.88 GAE mg/l and 26.77 to 41.86 mg/l, respectively. The soymilk produced from the mixture of sprouted soybeans and un-sprouted soybeans with the addition of either whole or peeled ginger significantly increased the crude protein content, ash content, calorific value and total phenolic content to 9.54%, 1.27%, 91.58 kcal/g and 11.88 GAE mg/l, respectively. In addition, it increased the overall sensory acceptability of soymilk. Conclusively, the use of sprouted soybeans and the addition of ginger should be encouraged to promote a more enriched soymilk beverage. Also, the developed dual-powered milk pasteuriser could be adopted for soymilk production. |
