Why do aspartame-containing health drinks have a health safety warning? - AnswersAspartame
contains phenylalanine, which can lead to mental retardation in individuals who lack the enzyme to
metabolize it.
What is PKU? - AnswersPhenylketonuria - the presence of phenylalanine in urine.
What are the steps involved in HFCS preparation? - AnswersCorn starch is converted to glucose and
then to fructose.
What are three critical components required for the Maillard reaction? - AnswersHeat, protein, and
sugar.
Is lactose a monosaccharide? - AnswersNo, it is a disaccharide.
How do fruits preserved in high sugar syrup stay longer? - AnswersSugar dehydrates the fruit,
reducing bacteria growth through osmosis.
What ingredient can thicken watery soup? - AnswersStarch, which is a polysaccharide that binds with
free water.
What does ADI stand for? - AnswersAcceptable Daily Intake.
What does FDA stand for? - AnswersFood and Drug Administration.
What compounds in hops give unique flavor and bitterness? - AnswersIsohumulone and alpha acids.
Why is barley preferred over other grains in beer making? - AnswersBarley has more starch and more
amylase, which converts starch to glucose.
What are reasons for beer haze? - AnswersSpoilage microorganisms and residual protein of
carbohydrates.
Differentiate between ale and lager beer. - AnswersAle is a top fermentor requiring warmer

Name a plant-based zero-calorie sweetener. - AnswersStevia.
Why is corn syrup sweet while corn starch is not? - AnswersCorn syrup contains free glucose, while
glucose in corn starch is connected.
Differentiate between caramelization and the Maillard reaction. - AnswersMaillard reaction involves
heat, protein, and sugar; caramelization involves sugar and heat.
Is aspartame heat stable? - AnswersNo, aspartame is not heat stable.
Is sucralose a plant-derived zero-calorie sweetener? - AnswersNo, stevia is.
Is DHA a saturated fatty acid? - AnswersNo, it is unsaturated.
Is omega-3 a saturated fatty acid? - AnswersNo, it is unsaturated.
What is HDL? - AnswersHDL is considered good cholesterol.
What is hydrogenation? - AnswersAdding hydrogen to oil to make it solid or semi-solid, which can
increase trans-fat and LDL.
What are cis and trans-fatty acids? - AnswersThey have the same chemical formula but different
structural formulas.
