Abstract
Spices are important supplements added to food as flavouring agents and/or a preservative and have
been in use all over the world for thousands of years. Various additives have been utilised over the years to spice our
food products. Synthetic additives, which have been in use, have come with various side effects, hence the need to
shift focus to the use of natural ones. Research into the production and utilization of indigenous food additives on a
large scale has not been undertaken in Nigeria. Even its utilization in food products to prevent or reduce food related
ailments or diseases have not really been done. This present work investigates the health benefits of the spice’s
extract on the glycemic load (GL) of the juice to consumers. Standard method was used for extraction of juice from
carrot, watermelon and pawpaw. Standard method [8] was equally used for the proximate composition (moisture
content, protein, fat, carbohydrate, crude fibre and ash), while soymilk was made from soybeans under laboratory
condition. The juices from the vegetable (carrot), fruits (watermelon and pawpaw), and soymilk were blended in
equal ratios and thereafter treated with A. danielli extract (1g-3g). Glycemic load (GL) of the samples was
determined by multiplying the weighted average of the glycemic indexes (GIs) of the mixed meal by the available
carbohydrate and dividing the product by 100. Available carbohydrate was determined by subtracting the fibre
content from the total carbohydrate. GL of untreated samples was 10.26, while treated samples recorded low values
(6.11-7.20). Standard values were 1-10, low GL; 10.1-20, medium GL; above 20.1 and above, high GL. The
outcome of the work could assist in utilising local spices for the full benefit of consumers.
