Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package

Overview of assessment

A person who demonstrates competency in this unit must be able to carry out artisan cheese making processes under the direction and supervision of the operations manager

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Critical aspects of assessment must include evidence of the ability to carry out processes in artisan cheese making including

following procedures for sanitation food safety quality assurance and environmental management in artisan cheese production

carrying out operations to

prepare milk for cheese making

coagulate milk through inoculation and ripening

separate and wash curd

carry out cooking and curing processes

package and label artisan cheeses according to procedures

Context of and specific resources for assessment

Assessment of performance requirements in this unit should be undertaken within the context of food cheese production Competency is demonstrated by performance of all stated criteria including the critical aspects and knowledge and skills elaborated in the Evidence Guide and within the scope as defined by the Range Statements applicable to the workplace environment

Assessment must occur in a real or simulated workplace where the assessee has access to

production process and related equipment manufacturers advice and operating procedures

sampling and testing equipment and procedures

methods and related software systems as required for collecting data and calculating yields efficiencies and material variances appropriate to the type of cheese and the production environment

Method of assessment

The following assessment methods are suggested

observation of candidate conducting cheese making processes as per operational procedures including the appropriate sampling and testing

written andor oral questioning to assess knowledge and understanding

thirdparty supporting statement

Guidance information for assessment

Evidence should be gathered over a period of time should cover all stages of cheese making and should be assessed for a range of cheese types Cheese can be produced in a real or simulated environment


Range Statement

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 legislation

legislation covering food safety, environmental management, OHS, anti-discrimination and equal opportunity.

Policies and procedures

Work is carried out according to:

company procedures

regulatory and licensing requirements

legislative requirements

industrial awards and agreements.

Safe work practices

Safe work practices are determined by risk assessment on site and may cover:

use of personal protective equipment (PPE)

manual handling procedures

exposure to hazardous substances

hazards in the processing environment, such as noise, moving equipment, scalds, and trips and falls.

Artisan production systems

Artisan production involves the making of cheese by traditional (non-industrial) methods. Emphasis is placed on observing and handling the cheese during processing. Artisan producers typically employ less than 30 people and do comparatively small production runs of specialty type cheeses.

Industrial production relies on mechanised equipment to perform a number of processing stages in the one machine. Production runs and output are of higher volume than artisan production. Industrial production can also include specialty cheeses if mechanised equipment is available.

Cheese types

Cheese types include any type of fermented cheese product, including

acid-coagulated (e.g. Cottage and cream cheese)

acid/heat-coagulated (e.g. Ricotta)

rennet-coagulated (e.g. Cheddar, Parmesan, Gouda, Swiss and Camembert).

Cheese inoculants

Cheese inoculants include:

the lactic acid bacteria which are added to the milk as a culture in inoculation

fungi.

Cheese additives

Cheese additives may be added to the milk after inoculation and include

calcium chloride

nitrates

colour

lipases.

Cheese adjuncts

Cheese adjuncts are microbial populations added to cheese in addition to the normal inoculants to:

provide consistency to flavour and texture

accelerate flavour development

produce specific attributes to meet market targets.

Cheese tests

Cheese tests may include:

testing for pH levels, moisture levels and salt levels

physical testing of cheese throughout production

testing for organoleptic properties.

Homogenising equipment

Homogenising equipment typically includes:

a supply pump

homogeniser block

homogenising valve

pressure gauge

back-pressure valve

pressure relief valve

pressure, micro-gap, centrifugal and ultrasonic homogenisers

related equipment, such as:

a deaeration unit.

Pasteurisation methods

Pasteurisation methods may be:

batch or continuous. For hard cheeses matured more than three months at no less than 2°C, heat treatment of milk (lower temperature for the same time) may be used.

Pasteurisation equipment

Pasteurisation equipment includes:

thermometers

recorder/controllers

flow diversion devices

pumps

heat exchangers

holding and cooling stages

filters and clarifiers

vacuum breakers

direct steam injection equipment.

Curd cutting

Curd cutting may be:

manual with cutting harps

automated with mechanical knives.

Cheese pressing

Cheese pressing may include:

pressing the cheeses to the required pressure to form the shape.

Salting methods

Salting methods may be by:

either brine salting or vat salting methods and may be carried out before or after pressing, depending on the type of cheese.

Packaging methods may include:

vacuum packaging in plastic, laminated foil, wax surfacing or wrapping in cloth.

Multi-phase cleaning systems

Multi-phase cleaning systems may include:

cleaning with a chlorinated alkaline detergent with a chelator, followed by water and acid rinses.

Food safety related information

Food safety related information may include:

milk counts

cheese bacterial counts
