- A formulator was trying to compare the iron (Fe) content of a competitor's milk product NEEDMO versus their product, BEADBAND. The analyst checked nutrition facts of NEEDMO and found out that it has a percent daily value (DV) of 11% DV of Fe. The 100% DV of Fe is equivalent to 18 mg. If a 30.00-g pack of BEADBAND contains 70 ppm of Fe, which between the two products contains more Fe?arrow_forwardBelow is a simple set of weights obtained while immersing potato slices in various sugar solutions over 30 minutes.

By convention, one Calorie (C), with a capital C, that is used for food is equal to one kilocalorie. On your Activity Sheet, paste a label or cut-out portion from food packaging indicating the number of Calories. (If you have no packaging at home, you may invent and draw your own label.) Convert these Calories into kilocalories and calories.arrow_forwardThe acceptable daily intake (ADI) of the additive E100 = 20 mg per kg of bodyweight per day.
