Food and Nutrition GCSE results 2019

These are the results for 2019 summer GCSE.

There were 5.5 million exams taken altogether and Food and Nutrition was taken by 0.9% of total.

The charts below show the results for male, female and total and the % for grades 7 , 4 and 1. The chart shows disappointing results for boys – only 50% got grade 4-7 so this needs looking at and maybe get evaluation on results in NEA 1, 2 and written exam.

Home Economics GCSE plods on with only 3528 candidates. Reading newspaper reports of results, we are not doing enough to get any mention of Food and Nutrition in the newspapers – this could lead to extinction!!

Aquafaba – the food science of cooking

Aquafaba is the liquid you strain off from a can of chickpeas and it’s used by vegans to replace egg in cooking.

Aquafaba is made up of water, protein and starch and the word comes from the Latin aqua – water, and faba – bean. Other beans as well as chickpeas made good aquafaba.

It can be used as a thickener, binder, emulsifier, foaming agent and gelling agent to replace egg.

The aquafaba science website says there is a lot more science to understand how it works.

The nutritional analysis for aquafaba is on The Nutrition Program. Use 3 tablespoons of chickpea water to replace one egg.

Other egg replacers include

  • 1/2 mashed banana
  • flax egg – 1 tbs of flax seed powder + 3 tbs water
