Abstract

spirulina algae, is a multicellular filamentous blue-green microalgae, is used in many countries of world including Egypt as human safe food. Spirulina algae used to enhance the nutritional value of food such as bakery products, due to their well balanced chemical composition as well as source of highly fatty acid chlorophyll , carotenoid, phycobilins, sterols vitamins, and other biological active compounds .
The aim of the present study  was  evaluated of organoleptic and  chemical properties of biscuits blends  fortified with different levels of  dried Spirulina platensis during storage period for 3 months at 25 ±5°C. The result indicated that biscuits blends fortified with dried Spirulina platensis as 0.5,1,2, and 3 % lead to improve the organoleptic physical properties fortified and chemical properties of biscuits blends when compared with unfortified biscuits sample (control). The chemical properties of biscuits blend lipid during storage revealed that acid value was decreasing upon the increasing Spirulina platensis in level biscuit blends than control. There were no significant difference in peroxide value between biscuit 1, biscuit 2 and control. Biscuit 3 and biscuit 4 recorded low increase of peroxide value during the storage time with significant difference after three months comparing with the control. The highest increase was recorded in biscuit control, while the lowest were in biscuit 4 with significant difference. Thiobarbituric acid (TBA) decreasing upon the increasing Spirulina platensis in level biscuit blends 1,2,3 and 4 than control while biscuit 2 and biscuit 4 recorded the lowest value.
Biscuits blends fortified supplemented with algae much more balance nutrient than control one. This supplementation also influences to acidity. Finally, using Spirulina platensis algae powder in the fortification of bakery products for its high nutritive value.
