Toast your Roast with Texture Analysis

Variations on ‘Roast Dinner’ are eaten for different occasions all over the world – a roast joint of meat, potatoes, vegetables and gravy, often followed by a stodgy pudding such as an apple pie.

This is a meal that consumers look forward to so it is important that the texture of each component is no less than perfect. This analysis would be carried out for the purpose of calculating ideal cooking times, in the case of a supermarket or a chain restaurant, or to test the quality of supplied ingredients.

Texture Analysis – Time for Tea!

Texture Analysers are made in the South of England, where afternoon tea stacked high on a triple tiered cake stand is a staple for any big celebration.  

Our customers around the world may be surprised to find some items here that aren’t so different from their own national food.

The first component of afternoon tea is a large, fluffy scone, cut in half and spread with sticky jam and clotted cream. There are regional arguments for whether jam or cream should be applied first, but in both cases cream and jam that are hard and difficult to spread cause the scone to break up under the knife, which is very undesirable. The softness of the inside of a scone can be assessed by preparing a cubic sample, having cut the crusts off, and performing a compression test with a large cylinder probe. A soft sample will yield under a low force.

The Perfect Texture of Lunch

A sandwich, a bag of crisps and a can of soda – the lunch eaten by millions of people around the world every day.

They are not aware of the meticulous testing that has gone into every stage of their meal, from the packaging down to the wheat flour used to make their bread. It is no surprise that food manufacturers focus so much of their effort into tailoring these items so they are a perfect compromise between cost and quality, to be pleasing to the customer but not expensive to manufacture.
