The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. |
Legislation | Legislative requirements are typically reflected in procedures and specifications. Legislation relevant to this industry includes:the Food Standards Code, including labelling, weights and measures legislationlegislation covering food safety, environmental management, OHS, anti-discrimination and equal opportunity. |
Policies and procedures | Work is carried out according to:company proceduresregulatory and licensing requirementslegislative requirementsindustrial awards and agreements. |
Cheese tests | Cheese tests may include:testing for pH levels, moisture levels, salt levels and fat and protein levelsmicrobiological testingchemical testingphysical testing of cheese throughout productiontesting for organoleptic properties. |
Cheese types | Cheese types may include the range of rennet-coagulated cheeses including:low heating temperature (<40°C) hard cheeses (e.g. Cheddar)high temperature (>40°C) hard cheeses (e.g. Parmesan and Romano)eye cheesesmould ripened cheeses (e.g. Camembert and Blue)bacterial surface ripened cheeses (e.g. Swiss Tilsit)fetapast filata cheeses (e.g. Mozzarella). |
Clarification procedures for raw milk | Clarification procedures for raw milk may include:cloth filterscentrifugal clarifiers and separatorsbactofugationmembrane (micro) filtration. |
Milk standardisation requirements | Milk standardisation requirements may:include standardisation of microflora, fat and protein, and casein/fat rationsrequire the addition of skim milk or skim milk solids, or the separation of cream. |
Pasteurisation methods | Pasteurisation methods may be:batch or continuous. |
Cheese inoculants | Cheese inoculants include:the lactic acid bacteria which are added to the milk as a culture in inoculation. |
Cheese additives | Cheese additives may be added to the milk after inoculation and include:calcium chloridenitratescolour (e.g. Annatto is added to Cheddar style cheeses to make a more orange colour)lipasesadjunct cultures (e.g. Propionibacteria added to milk for Swiss type cheeses results in the large eyes and characteristic flavour of these cheeses)enzymes (e.g. the use of lipase in some Parmesan and Romano style cheeses). |
Cheese adjuncts | Cheese adjuncts are microbial populations added to cheese in addition to the normal inoculants to:provide consistency to flavour and textureaccelerate flavour development produce specific attributes to meet market targetsAdjunct cultures are essential for the correct ripening of the cheese. |
Rennets | Rennets may include:enzymes (mostly chymosin) from animal stomachschymosin fermented by genetically modified organismsenzymes from microbial or plant sources. |
Key composition ratios of cheese | Key composition ratios of cheese include:salt to moisture ratio (S/M)moisture in the non fat substance (MNFS)fat in the dry matter (FDM)pH (acidity). |
Process control parameters to optimise yield | Process control parameters to optimise yield include:curd cutting and subsequent agitationheating and cookinghigh temperatures during pressing. |
Principles of optimising yield | Principles of optimising yield include:obtain highest MNFS with good qualitystandardise milk (P/F) to obtain maximum value for milk componentsminimise fat and protein losses in the whey. |
Processing factors to achieve moisture control | Processing factors to achieve moisture control include:cheese making timecurd particle sizecooking temperature. |
Preparation of the curd | For Cheddar and pasta filata cheeses, the curd particles may be allowed to matt before cutting and stacking as loaves, or stirred to prevent the particles from matting before the addition of dry salt. The loaves of matted curd are milled into small pieces before salting. The milled or stirred curd particles may be washed before saltingFor pasta filata cheeses, salted, part salted or unsalted curd is heated to ~60°C to plasticise the curd (typically by stretching in hot water or brine). The plasticised cheese is then moulded into its desired shape and the part salted or unsalted cheeses salted further in a brine solutionFor opened textured cheeses (e.g. Feta, Parmesan, Havarti, and most blue mould ripened cheeses) well drained curd is generally transferred from the vat into moulds before optional pressingEye and open textured cheese types are generally pressed before saltingFor surface ripened soft cheeses (mould and/or bacteria), curd and part of the whey is transferred into moulds to form the shape of the cheese before salting. |
Ripening procedures | Ripening procedures include:for most hard cheeses:the cheese may be sealed and allowed to ripen under either temperature controlled conditions (for rindless cheeses) or allowed to ripen under temperature and humidity controlled conditions before the cheese is sealed (for rinded cheeses)for white or blue mould ripened cheeses, soft bacterial surface ripened cheeses (e.g. Limburger) and hard bacterial surface ripened cheeses(e.g. Swiss Tilsit):the cheeses are allowed to ripen under temperature and humidity controlled conditions before the cheese is generally packaged in aerobic packaging. Some blue mould cheese and bacterial surface ripened cheese styles may be sealed at some stage during ripeningfeta cheeses:are generally ripened in a salt brine. |
Aging of hard cheeses | Aging of hard cheeses may be:from one to two months to several yearsTemperature must be monitored for rindless cheeses and temperature and humidity for rind, mould ripened and bacterial surface ripened cheeses. |
Packaging | Packaging may include:vacuum and/or gas flush in gas and moisture proof filmsurface drying as a protective rind followed by waxingoxygen permeable packaging for most mould and bacterial surface ripened cheese types. |
Multi-phase cleaning systems | Multi-phase cleaning systems require:cleaning with a chlorinated alkaline detergent with a chelator, followed by water and acid rinses. |
Records of cheese manufacture | Records of cheese manufacture may include:timing of operationstemperature loggingmilk and curd pH profilecurd weightmilk compositioncheese microbial countshooped yield curing and grading data. |
Food safety related information | Food safety related information may include:milk countscheese bacterial countsmanufacture and storage details. |
