The reason is unbalanced ratio between the fuel (gas) and air (Oxygen) resulting from defect in the parts of the cooker, either the regulator or the burning nozzles.
Correct ration will show blue flame indicating complete combustion operation.
If the ration is unbalanced due to defect in the cooker regulator or nozzles, the combustion will be incomplete and yellow flame accompanied with black carbon particles (soot) will be observed and will accumulate on the bottom of the pot with slight smell.
Spilled food on flames will result of yellow color but for different reason that is the burn of food solids , oils and liquids but it will expire once the spelled food is completely burned.

Yellow flame can be Na which is found abundantly in food. Since the question pointed out spillage, this certainly the answer.
One can also get a yellow flame by a lack of oxygen provided to the fire. A nice blue flame shows that the fire has the oxygen it needs.

A coward. Well, many pow's had lapses. One at Hanoi Hilton was used for propoganda reel, released to the media saying how wonderful things were there, all the while blinking the word torture in morse code. In five years living in a box and being tortured every 3- 4 hours, on slip still makes a hero. He did far more to protect and honor his fellow servicemen. It was far more than being "slapped around", do yourself a favor and educate yourself, or maybe you are too much of a yellow wimp as you say to even read about the suffering of others in Vietnam's Hanoi Hilton.

sodium is known for producing a yellow flame like in street lamps but I don't know if food would give yellow. it could just have someting to do with a temperature as that also affect colour

Not enough oxygen supply. Blue flame means there is enough oxygen for it to burn. Spilling food on the flame exstinguishes it's supply of efficent oxygen to burn. Sodium is a by product when the supply of oxygen is decreased then causing it to burn yellow.
