SOP for Microwave Oven Usage and Safety
SOP Number: Kitchen / F&B Production SOP – 17
Department: Kitchen / Food Production - Microwave Oven
Date Issued: 29-Nov-2018
Time to Train: 20 Minutes
Purpose of this SOP:
No chef shall misuse the microwave oven through lack of knowledge, and the principal use of microwave is as a heating process and not a basic form of preparation.
The Executive Chef and the Sous Chef should be responsible to ensure that the microwave oven is used properly by the kitchen staff. The hotel training and HRD department should develop and implement proper written Kitchen SOP's to ensure the same is implemented correctly throughout all the food preparation outlets.
Using Microwave Oven Standard Procedures:
Certain precautions should be taken when using a microwave oven.
Frozen prepared foods should be always thawed before heating.
Metal objects should never be put in the cooking chamber.
Sauces should be heated separately when possible.
Dishes with sauces can easily splatter and the crockery should be covered with paper towels or plastic wrap.
Covering the sauces dishes with paper towels or plastic wrap allows steam to escape during cooking.
Dishes or containers used in the oven should be heat tempered, ovenproof clear glass container without metal trim, china, ceramics, pottery without metal trim or metal base glaze.
The preserving method for the food can cause taste changes during the heating process, therefore each dish must be seasoned and tasted before serving.
Make sure that the microwave oven is kept spotlessly clean at all times.
The oven should be turned on only when the door is closed and when there is food in the oven to avoid damaging the magnetron tube.
Almost all products need to be prepared using one of the basic forms of preparation before heated in the microwave oven.
The microwave oven is particularly suitable for preparing convenience foods ie meals that have been pre-prepared and so requires minimum further preparation by the chef before serving to the guests.
Safety Tips While Using The Microwave Oven:
Always use only microwave-safe utensils when working with microwave ovens.
Never attempt to heat articles that are not appropriate for use in microwave ovens.
Always remove food from any plastic packaging before defrosting in a microwave oven.
Never use recycled paper products in microwave ovens unless they are specifically approved for microwave use.
Some recycled products including paper towels may contain minute metal flecks and interaction between microwaves and such metal can cause sparks and even flames.
If you have a fire in your microwave oven, turn it off immediately as this will then stop the fan so it won’t feed oxygen to the flames.
