DHA Clinical Dietitians - FAQ Sample Questions

A blast chiller can bring products from above 140° F to below 40° F in how many minutes?

Correct Answer:

90 minutes or less
a blast chiller is a specialized type of refrigeration equipment that is engineered specifically to cool food rapidly. the primary function of a blast chiller is to reduce the temperature of cooked food from above 140°f, which is within the danger zone where harmful bacteria can multiply quickly, to below 40°f in a short period of time. this process effectively minimizes the time food spends in the temperature range that supports bacterial growth, thereby enhancing food safety.

the correct answer to the question of how quickly a blast chiller can cool food from above 140°f to below 40°f is "90 minutes or less." this capability is crucial in commercial kitchens, particularly in scenarios where food needs to be prepared in advance and stored. by bringing the temperature down swiftly, the blast chiller not only ensures the safety of the food but also helps in preserving its quality, taste, and nutritional value.

blast chillers achieve this rapid cooling through the use of powerful fans that circulate very cold air across the food products. this method of forced-air cooling is much more effective and quicker than traditional refrigeration techniques, which rely on passive cooling. furthermore, the design of blast chillers often includes features that allow for the control of humidity, which helps in preventing the drying out of food and maintaining its texture.

typically used in cook-chill foodservice operations, blast chillers are essential in environments like large restaurants, hospitals, and catering operations where managing large volumes of food safely and efficiently is critical. by rapidly reducing the temperature of hot food and bringing it safely through the temperature danger zone, these chillers play a key role in modern food safety management systems.

The hormone that controls the blood glucose level is

Correct Answer:

insulin.

insulin is a vital hormone produced by the pancreas, specifically by the beta cells of the islets of langerhans. its primary role is to regulate blood glucose levels, ensuring they remain within a healthy range. insulin facilitates the uptake of glucose by cells in the body, which they use for energy or store for future use.

the process begins when we eat food that contains carbohydrates. these carbohydrates are broken down into simple sugars, primarily glucose, which then enters the bloodstream. as blood glucose levels rise, the pancreas is triggered to release insulin. insulin binds to insulin receptors on the surface of cells, activating a series of actions that allow glucose to enter cells. without insulin, glucose cannot efficiently enter cells and remains in the bloodstream, leading to elevated blood sugar levels.

in addition to facilitating glucose uptake, insulin also plays a role in glycogenesis—the conversion of excess glucose into glycogen. glycogen is stored in the liver and muscles and can be converted back into glucose when energy is needed. this storage capability helps maintain blood glucose levels within a normal range, particularly between meals or during physical activity.

furthermore, insulin inhibits the breakdown of fat and protein, an effect that further stabilizes blood glucose concentrations by preventing excessive release of glucose stored in fat and muscle tissues. this mechanism is crucial in preventing hyperglycemia (high blood sugar levels) and its associated risks, such as diabetes complications.

other hormones such as glucagon, cortisol, epinephrine, and thyroxine also influence blood glucose levels but in different ways. glucagon, for instance, has an effect opposite to that of insulin—it increases blood glucose levels by promoting the breakdown of glycogen to glucose in the liver. cortisol and epinephrine also raise blood glucose levels by stimulating glucose production and limiting insulin effects during stress. thyroxine increases overall metabolic rate, indirectly affecting blood sugar levels by influencing how quickly glucose is utilized.

in summary, while several hormones impact glucose metabolism, insulin is unique in its critical role of directly lowering blood glucose levels by promoting glucose uptake and storage. this makes insulin the primary hormone responsible for the day-to-day fine-tuning of blood glucose levels, essential for maintaining metabolic homeostasis.
