Egg whites and foams for meringues NEA 1

Liquid egg white used for meringue tests to discover what ingredients can be added

I’ve been doing more egg experiments this time with egg whites.

Have been using Liquid Egg white to save wasting so many eggs as there have been lots of tests to do.

The advantage of using Liquid Egg is that I can measure the egg white to use to experiment. My egg whites from eggs measured different amounts in millilitres so I had to beat some together then measure the same amount for experiments.

Use my book Food Science You Can Eat for more help

Love Food Love Science have an excellent website showing egg white foam experiments and the science behind egg white foam formation.

Protein foam formation shows how additives affect the stability of egg white foams.

The age of an egg affects its foaming ability and you can see the IFST.org tests here.

Egg white and cream of tartar whisk really well but egg yolk is flat

What whisk to use? I found that electric whisks were best to get a fair test for experiments as you can time the whisking time and level of whisking.

You can find the tests for gluten and bread, gluten and pasta and egg whites in our resource Food Investigations NEA 1 available August 2024

Meringue recipe testing

I used The Nutrition Program to present the results of the tasting. This is how it is done.

Click My Recipes and name one as Mini meringue test

Put in the basic meringue recipe in Ingredients.

I’m testing to see what happens when I add oil, vinegar and cream of tartar to egg whites.

Go to Star Profile.

For each Taster put in oil, vinegar and cream of tartar.

Then think of Descriptors for sensory appraisal – your tasting work.

I’ve chosen crisp, sweet, chewy, light foamy

Then tasted the meringues and given each a mark out of 5 where 0= not and 5= very.

This is a new function added for NEA 1 test – Click Hide Rating.

I can now see the Star Profile with each meringue tasted.

Then I can write my Evaluations.

Then Download as JPG.

Full marks I hope!!

Gelatinisation of starch – NEA 1

Food and Nutrition GCSE has an Investigation NEA which could be

Investigate the ingredients used to thicken sauces and soups

Look at the Book NEA 1 Food Investigations

This is how I do it:
Think what ingredients are used to thicken sauces and soups and which starch is best for recipes.

White sauce, Tomato sauce or soup, Fruit sauce…

Starchy ingredients thicken sauces when they are heated in liquid.

So test some starches:
Rice starch, cornflour, plain flour, arrowroot, potato flour … you choose.

Create a FAIR TEST. Mix the same amount of starch (10g) with the same amount of water (100ml).

Heat each one in the microwave and look every 20 seconds, stir and remove when it is thick.

Taste and test each one.

Use the Star Profile on the Nutrition Program to show your results:

First list the starches, then choose Descriptors – words to describe the results – thick, creamy, clear, glossy, tasty …

The Eatwell Guide

The Eatwell PlateThe Eatwell Guide shows the different types of foods and drinks we should consume – and in
what proportions – to have a healthy, balanced diet.
The Eatwell Guide shows the proportions of the main food groups that form a healthy,
balanced diet:
• Eat at least 5 portions of a variety of fruit and vegetables every day
• Base meals on potatoes, bread, rice, pasta or other starchy carbohydrates; choosing
wholegrain versions where possible
• Have some dairy or dairy alternatives (such as soya drinks); choosing lower fat and lower
sugar options
• Eat some beans, pulses, fish, eggs, meat and other proteins (including 2 portions of fish
every week, one of which should be oily)
• Choose unsaturated oils and spreads and eat in small amounts
• Drink 6-8 cups/glasses of fluid a day
If consuming foods and drinks high in fat, salt or sugar have these less often and in small
amounts.

Regularly consuming foods and drinks high in sugar increases your risk of obesity and tooth
decay. Ideally, no more than 5% of the energy we consume should come from free sugars*.
Currently, children and adults across the UK are consuming 2-3 times that amount.

Sugary drinks have no place in a child’s daily diet but account for a surprisingly large proportion
of the daily sugar intake of both children and adults. Almost a third of the free sugars consumed
by 11-18 year olds comes from soft drinks. We should aim to swap sugary drinks for water,
lower fat milk or sugar-free drinks including tea and coffee. Be sure to check the label for added
sugar.

8 tips for eating well
1. Base your meals on starchy foods
2. Eat lots of fruit and veg
3. Eat more fish – including a portion of
oily fish each week
4. Cut down on saturated fat and sugar
5. Eat less salt – no more than 6g a day
for adults
6. Get active and be a healthy weight
7. Don’t get thirsty
8. Don’t skip breakfast

Star Profile / Star diagram for Pastry

Here’s how you can use the Nutrition Program for GCSE Food Preparation and Nutrition NEA 1

Assessment 1: The Food Investigation Assessment 15% of total qualification

Task A Example: Shortcrust pastry should be crisp to the bite and crumbly in the mouth. It can be prepared using a range of different ingredients.
Investigate the working characteristics and the functional and chemical properties where appropriate, of the different ingredients needed to achieve a perfect shortcrust pastry.

Choose fats for pastries – for example, Trex, butter, lard and margarine, lard on its own.

Think of 5 words to describe pastry – crumbly, short, buttery, light, tough.

See our Tasting Word Bank.

Make and taste the pastries and put the results on My Recipes, Star Profile.

The Tasting words are listed as descriptors on the left side.

Then carry out several tastings and get marks out of 5.

The Nutrition Program creates the star as you can see below. You can then write the Evaluations of the different pastries as shown below and download your work.
