Hi. In the deep-fat frying processes and some published scientific articles remove the excess oil of the food matrix and then authors do the proximal analysis.

SInce, fat is one of the components of proximate composition so you consider the whole sample for moisture and ash content. However, for protein you can use fat free sample.
No they shouldn´t be dried before, because you are going to do a proximate analysis so you need all its components in the way they are. Besides in fried foods the content of water is used as a quality control parameter, because a high water percent could indicate a problem with the deep frying process and will probably reduce shelf life of the product.
In deep frying process allow the oil to drip off before subjecting them to proximate analysis but keep in view the amount of oil used Cox it will increase the fat content
All the best from Nigeria
Fried products like chips also have moisture content and it should be estimated for proximate composition
Moisture content is one of the parameter that is being checked during proximate analysis. So, first by drying out the sample in the oven you can calculate the moisture content and then perform other tests on the sample such as determining fat content, protein content, ash content, etc.
You don't need to dry them. Moisture determination is part of the proximate analyses, so just go ahead. I am wondering whether you would determine Ether extract (fat) content of the products. if yes, would the result be reliable? I ask this because i assume you used fat of some sort to fry the products.
appropriately the fried chips don't need to be dried. Drying will affect the moisture content of the fried chips and results may not be reliable so go ahead and determine the proximate composition.
If you intend to establish the effect of frying on the proximate composition, then you have to dry the chips, determine the proximate composition . Afterwards fry the chips and then subject the samples again to proximate analyses
No they don't need to be dried before, In proximate analysis you need all its components in the way they are.
