Everything has gone into the blender, including the fruit skin and seeds. The mixture looks smooth, but have those ingredients broken down completely?
When preparing pureed food for dysphagia, blending is a preparation step. The finished food still needs to meet the characteristics of the person’s recommended IDDSI level.
Depending on the ingredients and preparation method, pieces of skin, seeds or fibres may remain. Using a blender or Blixer does not, by itself, confirm that the food meets Level 4 Pureed.
Look beyond the smooth surface
A mixture can look smooth from above while containing small pieces that have not broken down.
The colour of the ingredients may also make particles difficult to see. Looking briefly into the bowl is not enough to establish the finished texture.
For Level 4 Pureed, the food needs to meet the relevant characteristics, including being smooth and without lumps. Staff should consider the whole preparation rather than assume that blending has addressed every texture concern.
Different ingredients need different preparation
A soft ingredient and a tough skin do not necessarily break down in the same way.
Seeds, fibrous parts and outer layers may need attention during preparation. What is required depends on the ingredient, the recipe, the equipment and the intended finished texture.
This does not mean every fruit or vegetable must always be peeled or sieved. It means staff need a suitable preparation method and must assess the result, rather than rely on a blanket rule about what can go into the blender.
Does using a blender or Blixer remove the need for testing?
No. The equipment prepares the food; it does not assign an IDDSI level.
A machine may produce a fine mixture, but the finished preparation still needs assessment using the relevant IDDSI testing methods and characteristics.
Neither the equipment’s name nor the time spent processing the food establishes that every ingredient has broken down as required.
If pieces remain, do not assume that another brief blend will necessarily resolve the problem. Follow the appropriate preparation process and reassess the finished food.
When might sieving or straining be needed?
Some recipes or preparation instructions may include peeling, removing seeds, sieving or straining to achieve the intended texture.
Follow the directions relevant to that preparation. If unwanted particles remain, seek advice about how to address them rather than serving the mixture because most of it looks smooth.
Sieving or straining is another preparation step. Completing it does not confirm all the other Level 4 characteristics, such as whether the food is sticky or has liquid separating from it.
Assess the finished puree using IDDSI testing methods
For Level 4 Pureed, the relevant Fork Drip and Spoon Tilt tests provide information about how the food behaves.
These results need to be considered alongside the full definition, including smoothness, absence of lumps and the other required characteristics.
A satisfactory Spoon Tilt result should not be used to dismiss visible pieces of skin or other material that raise a texture concern.
Follow the complete official IDDSI testing methods, with testing under the intended serving conditions, particularly temperature.
Adding liquid does not remove particles
A common preparation question is whether more liquid will help the mixture blend.
Any addition needs to follow an appropriate recipe or preparation process. Adding liquid changes the preparation, but it does not establish that skins, seeds or fibres have been removed or broken down.
It may also change the consistency of the food.
After modification, reassess the finished preparation against all the relevant requirements. Avoid repeatedly adding ingredients until it simply looks right.
Check what is added after blending
The puree may be smooth when it leaves the machine, then have a sauce, topping or garnish added.
Those additions become part of the meal. They need to be considered against the intended food level and the person’s recommendations.
A small amount of chopped herbs, seeds or another topping should not be overlooked because it is decorative.
Consider the meal as it will actually be served.
What should staff do if particles remain?
Pause and follow the service’s process for resolving the concern.
Describe what was found. “Pieces of skin remain in the mixture” gives the preparation team more useful information than “the puree is wrong.”
Further preparation or a replacement may be needed, followed by assessment of the finished food.
Do not offer an uncertain preparation to the person to see how they manage it. Their response should not be used to decide whether the food meets Level 4.
Make preparation instructions clear across the team
A useful recipe should explain the preparation needed for its ingredients, including any removal of skins, seeds or fibrous parts.
Staff also need to know how to assess the finished food and whom to contact when the result is unclear.
If an ingredient or product changes, communicate that change. A method that worked for one preparation should not automatically be assumed to produce the same result with another.
Help staff connect preparation with testing
Dysphagia education and training for aged care staff should distinguish between processing food and assessing its finished characteristics.
Practical learning can help workers understand why a blended appearance is not enough, when further preparation may be needed and how to use IDDSI testing methods.
Swallowing & Dysphagia Support provides IDDSI training for care and kitchen teams. Contact us to discuss training for your Sydney organisation and practical questions about preparing pureed food for dysphagia.
This article provides general education. Follow the current official IDDSI definitions and testing methods, the relevant preparation instructions and the person’s individual swallowing recommendations.
