What are high risk foods?

High risk foods share a tendency to spoil as a result of unsuitable storage conditions or improper cooking methods. Meats, fish, gravy, sauces, shellfish, dairy products, pasta and even cooked rice are all examples, and the smallest errors can lead to contamination.

Which process is also called product recovery?

Explanation: Downstream processing implies manufacture of a purified product fit for a specific use, generally in marketable quantities, it also refers to the recovery and purification of biosynthetic products, particularly pharmaceuticals, from natural sources such as animal or plant tissue or fermentation broth.

What is the safest way to eat eggs?

Overall, shorter and lower-heat cooking methods cause less cholesterol oxidation and help retain most of the egg’s nutrients. For this reason, poached and boiled (either hard or soft) eggs may be the healthiest to eat. These cooking methods also don’t add any unnecessary calories.

What are the phases of growth?

There are three phases of growth – meristematic, elongation and maturation. We can understand this better by looking at a seed. We already know that the tips of roots and shoots exhibit continuous growth and hence are meristematic. The cells in this region are rich in protoplasm and have large nuclei.

What food is at a temperature that allows bacteria to grow?

Warmth – the ‘danger zone’ temperatures at which bacteria grow best are between 5ºC and 63ºC. Food – like any other living things, germs need food to grow. High-risk foods that bacteria love best include dairy products, meat, poultry, fish and shellfish.

Which condition is correct according to the growth of cells in beginning?

Which condition is correct according to the growth of cells in beginning? Explanation: Growth always appears much slower at the beginning of culture because the number of cells present is small. 5. The specific growth rate of cells is independent on the concentration of nutrients in the medium.

Is cooked pasta a high risk food?

Most people are surprised that cooked pasta and rice is a food poisoning risk. In fact if you are entertaining and your fridge is full it is often the cooked rice or pasta that is left out. Dried rice and pasta will last a considerable time so follow the best before date on the packaging.

What are the 4 conditions which allow bacteria to grow?

Most bacteria grow best within certain ranges of temperature, and have specific requirements related to their need for air, the proper amount of water, acid and salt. By controlling nutrients, water, temperature and time, air, acidity, and salt, you can eliminate, control, or reduce the rate at which bacteria grow.
