Coating the substrate is a standard industry practice and also a necessity in fried snack. Chefs also add flavouring to this flour coat. The challenge is the synergy of the coating system with the base matrix. If this is not correct, it leads to soggy chewy product, with moisture being the probable reason which being loosely held in the base matrix, on frying, slowly gets to the coating system and makes it soft soggy and chewy.
Dine in or Delivery, consumers tend to prolong time before consuming their fried snack.
The occasion may be socializing or celebration, people keep reheating their food or refrigerating the left overs. This puts Fried snacks in a odd spot because when reheated later crispiness cannot be regained.
Lack of correct coating system pairing with substrate may lead to soggy, chewy or otherwise dry and burnt product when fried at 185ºC - 195ºC
Be it Styrofoam, poly coated paper box or aluminium foil, any packing that suffocates the fried items later contributes to its sogginess. Though vented paper containers help solve the problem with crispness, it also cools down the food quickly.
A tight wrap/packing will seal in steamy moisture and make your fried snack soggy, if it isn’t eaten quickly due to moisture condensation.
