Size Does Matter!!!

Grain size that is. Working in an application lab/kitchen and with people that have a lot of technical information on food processing really does provide a lot of interesting facts. For example, mesh size a.k.a. the size of the powder particles. Well, depending on the size, the powder can have different colours, dispersion rates, gel products, textures/mouthfeel, and flavour release! Yup, size matters after all. Texture due to mesh size is a no-brainer, it's self-explanatory. It's the flavour release that is more interesting. Bigger granules require more chewing before the flavours are detected. With that said, the flavour can be gradual, BAM-in-your-face, or only comes out in the end, depending on the mesh size.

This is an image I took using my iphone, so pardon the lower-than-usual image quality. All these came from the same dehydrated yams, just grinded to different mesh sizes. Notice the colour difference?

Arranged from left to right, largest mesh size to smallest.
