Harp – A tool with cutting wires used to cut curds in cheesemaking.

Heat-Acid Precipitated Product – A type of coagulation where the acid is added to milk that has been raised to a high temperature.  This process results in a higher yield and lower acidity in the end product because the whey proteins are denatured, allowing coagulation, and so can be recovered in the cheese. The recovered whey proteins have a high capacity to bind water, allowing a high-moisture, firm cheese.

High Fat – FDM in dairy products/cheese is above 60%.

High Temperature Short Time (HTST) – Pasteurization of milk heated to 161°F and held there for 15 to 30 seconds.

Homogenization – Homogenization or homogenization is any of several processes used to make a chemical mixture the same throughout. The fat in milk normally separates from the water and collects at the top.

Penicillium candidum – A variant of the mold P. camemberti, which is a typical, white bloomy mold that becomes grayish after several days. The P. candidum variant remains white and is the trademark of a bloomy rind cheese. This surface mold, given the proper salt and moisture, will develop a rind that breaks down amino acid chains from the outside in, creating an increasingly soft, buttery texture with time.

Penicillium Glaucum – The lesser known strain of blue mold used in some, typically milder, blue cheeses, such as Gorgonzola. See Penicillium roquefortii.

Penicillium Roquefortii – The blue-green mold typical of blue cheeses, responsible for the breakdown of fats and the resulting piquant flavors. In addition, this mold de-acidifies the cheese curds, which softens the texture over time.

Phenolic – Cow-like.

Phenois – Metabolizing of amino acids during aging which creates certain flavor profiles including smoky and barnyard.

Pinking – Development of light to dark pink color on surface of the cheese. May be considered a defect caused by oxidation of annatto.

Pressing – One of the steps in cheesemaking that is uses pressure to achieve desired moisture content and texture.

Pressed Cheese   – Any cheese that is pressed after coagulation, cutting, and cooking (if applicable), draining of whey, and shaping of curds. Semisoft, firm, and hard cheeses are all pressed to achieve a smooth, uniform paste, while most bloomy and blue cheeses are not pressed at all, hence their lighter, moister texture.

Probiotics – Beneficial microorganisms found in milk

Propionibacterium shermanii – A bacteria found in milk and dairy products that breaks down lipids into free fatty acids and ferments lactate, resulting in the CO2 that creates the eyes and sweet, nutty flavors in Swiss-style cheeses.

SSOP – Sanitation Standard Operating Procedures.

Salmonella – Enterobacteria found in raw or undercooked food and closely related to Escherichiagenus, it causes infections characterized by diarrhea, fever, vomiting, and abdominal cramping.

Salting – Adding salt to the curd which helps draw off more moisture and arrests the growth of bacteria and retards acidity development. Salting signifies the end of draining whey and the beginning of affinage.

Sanitizer – A cleaning product that reduces disease-causing organisms to safe levels by reversing the microbe cell wall charge from negative to positive, resulting in death of the microbe.

Saponified – Soapy.

Scalding – Heat treatment of the curd. The primary function of scalding is to shrink the curd and expel moisture.

Sechage – French for drying.

Shell – Rind of cheese

Short – Lack of elasticity. May be considered a defect caused by too rapid acid development; excessive acid development or excessive calcium loss.

Silage – A mixture of plants and grasses fermented in a silo.  The fermentation process is chemically equivalent to the pickling of sauerkraut.  It can cause tainted or off flavors in milk and cheeses.  This stresses the importance of knowing what the milk-producing animal has been fed.  

Slip Skin – The rind detaches from the cheese, usually a bloomy rind, due to high humidity during ripening or storage conditions.

Slitty – “Slitty” means that cheese contains narrow, elongated slits which are generally associated with a cheese that is “gassy” or “yeasty”. Slits in cheese having this characteristic may sometimes be referred to as “fish eyes”.

Solids – The fats and proteins in milk.

Somatic Cell – White cells in milk used to determine how clean milk is.

Somatic Cell Count   – Primarily the number of while cells per ml of milk. The higher the count, the more likely the animal is to developing mastitis. Legal count must be below 750,000 per ml 50% of healthy cows in US are under 100K; 80% are below 200K. Above 300K is cause for concern

Staphylococcus aureus – A bacterium found in the human respiratory tract and on the skin, it is a causal agent of MASTITIS in dairy cows.  It can be transferred to food during handling.

Starter Culture – A preparation of bacteria that, when added to milk, consumes lactose and produces lactic acid. The resulting acidification is one of the preserving techniques used in cheese making.

Thermization or thermalization – Heating milk to 135-145f and holding there for 15 to 30 seconds. Kills 95% of the bad stuff without killing some of the good microflora. Milk that is heated in this manner is still considered raw per the FDA definition of pasteurization.

Thermophile – An organism — a type of extremophile — that thrives at relatively high temperatures, between 45 and 122 °C (113 and 252 °F). Many thermophiles are archaea.

Thermophilic eubacteria are suggested to have been among the earliest bacteria. Unlike other types of bacteria, thermophiles can survive at much hotter temperatures, where as other bacteria would be damaged and sometimes killed if exposed to the same temperatures.

Tomme – A French term indicating a round of cheese, most often made from a single herd, from cow’s milk, and with a natural rind. Tommes are often identified by their region of origin as in Tomme de Savoie. Small tommes are known as tommettes.

Trans Fat – Unsaturated fats that are not common in nature but generally created artificially.

Transhumance – This term describes the annual movement of dairy livestock from the valleys to Alpine pastures

Umami – Savory taste; one of the five basic tastes.

Vat pasteurization – A method of heating milk to retain natural enzymes and beneficial bacteria inherent in milk.  Milk is heated to 145˚ F for 30 minutes and then quickly cooled.  More expensive than other pasteurization processes, but intended to preserve flavor and health properties.

Vibrio – A bacteria that can cause foodborne infection.

Washed Rind – A style of cheeses that are washed in brines to kill bad bacteria/mold and encourage the growth of B. linens. B. linens creates the pungent aroma and orange color of the rind.

Washing the Cured – Replacing a measure (often a third) of whey from the vat with water. Washing helps to control acidity growth by reducing the amount of lactose and bacteria. Cheeses like Gouda are often washed curd cheeses.

Water Activity – Water in food which is not bound to food molecules can support the growth of bacteria, yeasts and molds (fungi). The term water activity (aw) refers to this unbound water. The water activity of a food is not the same thing as its moisture content. Although moist foods are likely to have greater water activity than are dry foods, this is not always so; in fact a variety of foods may have exactly the same moisture content and yet have quite different water activities.

Wavy – Portions of paste appearing lighter in color in waves. May be considered a defect caused by inadequate dilution of coagulant, agitation or vibration during the setting of the milk.

West County Farmhouse Cheddar – EU protected cheddar that can only be made in the English counties of Somerset, Devon and Cornwall.

Whey – The liquid held within the curd. Whey contains water, lactose, and a variety of proteins that are not captured in the initial coagulation. Whey cheeses, like ricotta, form a curd primarily under the influence of heat. Whey is also used as feed.

Yeast – Single-celled microorganism fungi that can ferment carbohydrates into alcohol and carbon dioxide. Some species are opportunistic pathogens that can cause infection in a compromised immune system.

Zoonosis – An infectious disease transmitted from animals to humans and vice versus.
