Production Cheese

Cheese Production Fundamentals

Cheese production transforms milk into solid form through coagulation and moisture removal. This process begins with acidification using bacterial cultures or direct acid addition. Rennet enzyme introduction then creates curds by separating solid milk proteins from liquid whey.

The curd treatment stage determines cheese texture through cutting, cooking, and pressing techniques. Salting occurs through brine immersion, surface rubbing, or direct mixing into curds. Final maturation periods range from fresh cheeses consumed immediately to aged varieties requiring years of development.

Milk Selection and Preparation

Cheesemaking utilizes milk from cows, goats, sheep, or buffalo with varying fat content. Raw milk preserves native microorganisms while pasteurization ensures safety through heat treatment. Standardization adjusts milk components to achieve consistent composition across production batches.

Milk quality directly impacts final cheese characteristics including flavor and texture. Temperature control during transportation and storage prevents premature spoilage. Additional cream may be incorporated to create richer double or triple cream cheese varieties.

Coagulation Methods

Acid coagulation relies on lactic acid bacteria converting lactose into acid over hours. This method produces fresh cheeses like cottage cheese and queso fresco. The acid causes casein proteins to precipitate without enzymatic action.

Rennet coagulation uses chymosin enzyme to create firm curds within thirty to forty minutes. Most semi-hard and hard cheeses employ this method. Mixed coagulation combines both acid development and minimal rennet for transitional textures.

Curd Processing Techniques

Curd cutting size determines moisture retention with smaller cuts yielding drier cheese. Cooking temperatures range from 35°C for high-moisture cheeses to 55°C for parmesan styles. Stirring intensity and duration further modify final cheese structure.

Cheddaring involves stacking and turning curd blocks to expel whey and develop texture. Stretching creates pasta filata cheeses like mozzarella through hot water treatment. Washing curds with water reduces acidity for sweeter flavored cheeses such as gouda.

Ripening and Affinage

Cheese aging occurs in controlled environments with specific temperature and humidity ranges. Surface-ripened cheeses develop rinds through mold growth like Penicillium camemberti. Internal ripening relies on enzyme activity within the cheese paste.

Affinage represents the specialized craft of cheese maturation through regular turning and washing. Washed-rind cheeses develop sticky orange surfaces from brine or alcohol solutions. Blue cheeses feature internal veining from Penicillium roqueforti inoculation before forming.
