Identify the biochemical properties of food

This unit covers the skills and knowledge required to identify and apply a knowledge of biochemical substances and reactions to food product development and processing.

Application

This unit applies to technical and management staff who have responsibility for maintaining product safety, quality and efficiency in food processing. The unit can apply to all sectors of food production including general food production, meat and seafood industries. The unit includes applying knowledge of food biochemistry to establish and monitor food safety, quality and processing performance.

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 design and manage food processing operations based on a knowledge of the biochemistry of food processing.

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

Critical aspects of assessment must include evidence of a detailed understanding of biochemistry of food, including the ability to carry out basic chemical tests to identify biochemical compounds, use biochemical knowledge to predict the effects of processing, storage and additives in food processing, and produce or extract representative samples of biochemical compounds.

Context of and specific resources for assessment

Assessment of performance requirements in this unit should be undertaken within the context of food technology. 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:

laboratory and related equipment, manufacturers’ advice and operating procedures

methods and related software systems as required for collecting data and calculating yields, efficiencies and material variances appropriate to production environment

tests used to report relevant product/process information and recorded results.

Method of assessment

The following assessment methods are suggested:

Observation of candidate conducting a range of tests and sampling procedures

Written and/or oral questioning to assess knowledge and understanding

Completing workplace documentation

Case studies

Field Reports

Third party support from experienced practitioner.

Guidance information for assessment

Evidence should be gathered over a period of time in a range of actual or simulated environments.


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.
