The organoleptic quality of the food refers to its sensory properties, that is its look, taste, smell, and texture. Examples of hurdles in a food system are high temperature during processing, low temperature during storage, increasing the acidity, lowering the water activity or redox potential, and the presence of preservatives or ...
Boiling is the method of cooking food in boiling water or other water-based liquids such as stock or milk. [13] Simmering is gentle boiling, while in poaching the cooking liquid moves but scarcely bubbles. [14] The boiling point of water is typically considered to be 100 °C (212 °F; 373 K), especially at sea level.
Oil based cooking techniques have significant surface interactions that greatly affect the quality of the food they produce. These interactions stem from the polar oil molecules interacting with the surface of the food. Water based techniques have far less surface interactions that affect the quality of the food.

In cooking, reduction is the process of thickening and intensifying the flavor of a liquid mixture, such as a soup, sauce, wine or juice, by simmering or boiling. [1] Reduction is performed by simmering or boiling a liquid, such as a stock, fruit or vegetable juice, wine, vinegar or sauce, until the desired concentration is reached by ...
Preservatives can expand the shelf life of food and can lengthen the time long enough for it to be harvested, processed, sold, and kept in the consumer's home for a reasonable length of time. One of the age old techniques for food preservation, to avoid mold and fungus growth, is the process of drying out the food or dehydrating it.
When the process is applied to food and the water is evaporated and removed, the food can be stored for long periods without spoiling. It is also used when boiling a substance at normal temperatures would chemically change the consistency of the product, such as egg whites coagulating when attempting to dehydrate the albumen into a powder.
A pressure cooker is a sealed vessel for cooking food with the use of high pressure steam and water or a water-based liquid, a process called pressure cooking. The high pressure limits boiling and creates higher temperatures not possible at lower pressures, allowing food to be cooked faster than at normal pressure.
