Qualification -
Unit of Competency AMPA404 - Conduct and validate pH and temperature declines to MSA standards
Description
Employability Skills
Learning Outcomes and Application This unit covers the skills and knowledge required to accurately calibrate and maintain pH equipment, conduct pH and temperature declines and weekly monitoring, as well as to validate results to ensure conformance to the pH and temperature window.It is a license requirement for Meat Standards Australia (MSA) enterprises to achieve the pH and temperature window.The skills and knowledge gained from this unit will allow individuals to monitor pH or temperature window to AUS-MEAT and MSA standards. This unit is suitable for people working in Quality Assurance (QA) or a company grading role.This unit must be delivered and assessed using Australian meat industry standards and regulations.No occupational licensing, legislative or certification requirements are known to apply to this unit at the time of publication.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Competency must be demonstrated over time and under typical operating and production conditions for the enterprise.

The application of competency is to be assessed in the workplace. Assessment is to occur under standard and authorised work practices, safety requirements and regulatory requirements.

A minimum of three forms of assessment must be used.

Assessors must satisfy current standards for RTOs.

4.2 Identify reasons for non-conformance

4.3 Conduct trials to achieve window conformance

Evidence must demonstrate the candidate's consistency of performance over time at production speed.

The candidate must conduct and validate pH and temperature declines to MSA standards.

The candidate must:

collect information on live animals for use in pH and temperature monitoring

conduct monthly and weekly monitoring of the pH and temperature window

observe, time and follow carcases through the slaughter floor recording the following:

carcase information

chiller number

immobiliser information (if applicable)

rigidity probe information (if applicable)

stimulation information (if applicable)

time entering the chiller

time stunned

analyse results to verify conformance

apply relevant communication and mathematical skills

generate individual and lot average graphs to show pH and temperature window conformance

identify and apply relevant workplace health and safety, regulatory and workplace requirements

maintain currency of knowledge through professional development or self-directed research

operate and calibrate pH and temperature readings

suggest corrective action procedures

The candidate must demonstrate a broad factual, technical and theoretical knowledge of:

the scope and nature of MSA standards

impact of electrical stimulation on pH decline

impact of chilling factors on pH and temperature decline

how the time it takes a carcase to reach the chiller can impact on the rate of pH decline

pH and temperature window

how cold shortening occurs and characteristics of cold shortened product

how heat shortening occurs and characteristics of heat shortened product

how other electrical inputs can impact the rate of pH decline

the impact of slaughter floor temperature on rate of pH and temperature decline

glycogen and the relationship between stress and pH

what pH is and its importance for eating quality
