Q. Why do some products state 'no preservatives, no artificial colours and no artificial flavours' but the list of ingredients then lists flavour enhancers (621, 627, 631) flavours (270, 262) and colours (160a)?
A.At first glance, Diet Coke and Coke Zero appear to be identical. Both contain no kilojoules (calories) and no sugar. Both are artificially sweetened with (the same amount) of aspartame and acesulfame K and therefore have the same ‘sweetness’.
A. It's easier to deal with the second part of this question first.
Permeate is made when whole milk is filtered through a fine 'sieve' or membrane using a technique called ultra-filtration. This filtering separates the lactose (also called milk sugar), the vitamins and the minerals from the milk protein and fat.
The consumption of additives in food is a vexed issue. On the one hand, no-one plans to consume them in the first place and some – a limited number – have been linked to health problems ranging from asthma, wheezing, rashes, digestive upsets, behaviour problems in kids resulting in overactivity, lack of concentration and impulsiveness (hyperactivity).
A.Additives are used to extend shelf life or make a food more convenient or attractive or to be lower in kilojoules/calories. There are around 300 additives permitted for use in Australia and you can group them into around 20 different categories based on what function they perform.
A. Emulsifiers are substances which stabilise mixtures and prevent oil and water from separating. In a salad dressing, for instance, an emulsifier keeps the oil and vinegar mixed so they don't separate into two layers on standing.
