The taste of cheese

Cheese is the generic name for a group of fermented milk-based food products. Over 2,000 natural cheeses have been named and identified, including "original" cheeses, as well as "imitations" of originals.

In cheese, the yeast seems to take part in several microbial interactions important for the fermentation and maturation process of several cheeses.

Dairy-related attributes (dairy fat, dairy sour, and dairy sweet), fundamental tastes (bitter, salty, sour, and sweet), and sharp and astringent were found in every type of cheese.

The volatile flavor compounds in cheese originate from degradation of the major milk constituents; namely lactose, citrate, milk-lipids, and milk proteins (collectively called caseins) during ripening which, depending on the variety, can be a few weeks to more than 2 years long.

The breakdown of protein is important for cheese taste, and some off-flavors, for example, bitterness, but are unlikely to contribute much to aroma. The breakdown of protein also softens the cheese texture by breaking down the casein network. Compounds arising from the catabolism of free amino acids contribute directly to cheese taste and aroma.

Bitterness, origination from nitrogen containing compounds, especially small peptides, is one factor that can limit the acceptability of cheese. NaCl is responsible for the salty taste, and other salts often contribute to the bitter taste.

Chevre had the highest goaty flavor and was rated among the highest for dairy sour flavor, sour taste, and astringency. Chevre had very low dairy flavor notes.

Gruyere could be considered a sweet cheese; it was higher than most cheeses in both sweet taste and dairy sweet, and was low in bitterness.

Provolone cheese

With a subtle flavor and a pale yellow color, provolone is widely used in Italian cooking. Young provolone is dolce, or sweet, aged up to two three months. After it ages and becomes spicier and more granular, the cheese is called picante.

Like mozzarella, provolone is also a pasta filata or stretched-crud-type cheese. It has less moisture than mozzarella and is additionally cured by suspending in ropes or plastic mesh at 85% humidity.

It has a stringy texture. The minimum milk fat content is 45% by weight of the solids, and the maximum moisture content is 45%.

Like reduced-fat mozzarella, reduced fat provolone - which works in both cooked and cold dishes - will save up to 5 percent of fat per ounce when compared with the full-fat product.

For cooking, Provolone is multipurpose. It can be used on pizzas, in lasagnas and for flavorful casseroles. It goes well with tomatoes and fruits such as pears, grapes and figs.

Sensory properties of milk

The sensory properties of milk and milk products are a consequence of composition, which may be manifested in ways that relate to notions of quality.

Milk sensory properties of appearance texture and flavour are largely determined by the fat concentration on the product.

Fat molecules are too large to stimulate taste or smell, but do produce tactile sensations.

Many of the compounds identified as contributing to the flavour and aroma of milk are derived from the fat and the milk fat globule membrane.

The chemical and physical properties of milk products are influenced by raw milk quality, manufacturing processes, storage condition and associated process controls.

The bland mouth-feel if milk is a consequence of the emulsion structure, while the slightly sweet and salty taste results from the balance between lactose and milk minerals.

The whiteness of liquid milk is caused by the light scattering of milk-fat globules, colloidal caseinate and colloidal calcium phosphate though the presence of carotenes is importance to the yellow color of milk-fat.

Whole milks are whiter and more viscous that’s skimmed milk. Also, the flavour of whole milk is more intense due to the naturally occurring fat flavour compounds.
