If we hold the hot food on proper temperature 60 Celsius or above ,what's the longest time that keeps food safe?

Discard any hot food after four hours if it has not been maintained at a temperature of 60ºC or higher. When you display hot food, e.g. on a buffet, you should use suitable hot holding equipment to keep it above 60°C. If this is not possible, you can take food out of hot holding to display it for up to two hours, but you can only do this once. Food that has not been used within two hours, should either be reheated until it is steaming hot and put back in hot holding or chilled down as quickly as possible to 8°C or below. If it has been out for more than two hours throw it away. Remember to keep the food at a safe temperature until it is used. If you do take food out of hot holding to display it, remember not to mix new food with the food that is already on display. This could lead to the older food being left out for too long.

If your food temperature is more than 60C there is no problem at all from food safety point of view as pathogens will not grow more than 60C, however there is a issue of quality because by keeping the food on a continuous heat of above 60C you will find some dryness and texture changes which is clearly an issue of quality of the product.

Now from food safety point of view as others mentioned in the answers as per FSA (Food Standard Agency) UK guideline any food having temperature less than 60C for more than 4 hours must not be used. I hope you get the answer...

We can keep hot food at 60°C or hotter until it’s served, but temperature must check every 2hr and if temperature less than 60°C must heat the food and container to above 75°C to maintain temperature >60°C , and if food temperature be less than 60°C more than 2hr the food must discard..

okey

thats depending on case of this food and type this food....

this tep. 60c and abouve enough for distruction most rhe bacterial ...

if we use this food in the first time ...i am advice to use it around 2 hours maximum in room temp.

i am advice also if we want re- heating this food ...i think we will make this one time only

and use it directly through 2 hours also

ok.?
