When is native starch sufficient?
It can be a good starting point when heat and shear are moderate and there is no strong acid or freeze-thaw challenge. For Potato Starch sourcing, separate whole-potato-solids needs from thickening and binding functions first. If the project also compares Potato Flakes or Potato Granules, review viscosity method, process conditions, sample, TDS and COA separately.
Why is one viscosity number not enough?
Viscosity depends on solids, temperature, shear and the test method, so the conditions must be stated. For Potato Starch sourcing, separate whole-potato-solids needs from thickening and binding functions first. If the project also compares Potato Flakes or Potato Granules, review viscosity method, process conditions, sample, TDS and COA separately.
What if the food is frozen or highly sheared?
A modified starch direction may be more appropriate than simply increasing the native starch level. For Potato Starch sourcing, separate whole-potato-solids needs from thickening and binding functions first. If the project also compares Potato Flakes or Potato Granules, review viscosity method, process conditions, sample, TDS and COA separately.
Can viscosity numbers from different Potato Starch suppliers be compared directly?
Only when concentration, temperature programme, instrument, speed and test method are comparable. Buyer approval should also include sample behaviour in the actual formulation. For China Potato Flour sourcing, start from the finished food and process, then define whether Potato Flakes or Potato Granules should enter the first trial. Keep the approved sample, specification, TDS, COA and quotation aligned to the same grade.
Can we request a sample, TDS and COA before a bulk order?
Yes. After the exact product direction is defined, discuss the sample and applicable technical documents together. Share the finished food, key process, target performance and expected volume so the sample grade, TDS, COA and quotation refer to the same sourcing project.
What information helps us receive a more accurate quotation?
Provide the product or application, expected volume, packing, destination country or port and the preferred trade term such as FOB, CFR or CIF. Add any technical, certification or labelling requirements before quotation. For China Potato Flour sourcing, start from the finished food and process, then define whether Potato Flakes or Potato Granules should enter the first trial.
