In the present study, production and using possibilities of powder of macaroni boiling water (PMBW)
were investigated. After cooking process of macaroni, firstly pre-drying was carried out at 50 C in a
drying oven and then lyophilization process was conducted to obtain final powder product. Physicochemical
characterizations like total dry matter, ash, fat, protein, pH, aw and color properties were carried
out and also technological properties of sample were determined. Both macaroni boiling water and the
final powder product were examined in terms of microbiological analyses. It was found that macaroni
boiling water had to be processed in 6 h after cooking if the cooking water was stored at room temperature.
Also, the duration of 12 h after cooking was found to be limit level for microbiological safety of
cooking water if it was stored at þ4 C. Besides, scanning electron micrographs of particles and fatty acid
and mineral profile of the final powder product were determined. Macaroni boiling water is a by-product
having a lot of nutrients and in this study it was proved that utilization of this by-product may be
feasible. The macaroni boiling water can be used as a food ingredient and also as an enrichment agent
