Part 6 - Food Preparation Instructions
Boiling water
Except where other instructions are provided, ' boiling water' means that the food is to be boiled in ' unsalted' water.
Crush
When the preparation instruction states 'crush' , then the following procedure is to be followed:
- Place food into a plastic bag.
- With a rolling pin crush food so that the food pieces are no larger than half a centimetre in any one direction .
Chop
Except where other instructions are provided, 'chop' means that the food is to be chopped with a stainless steel knife into pieces no larger than 1 cubic centimetre. In most cases, it should be possible to chop into pieces much smaller than this, which is desirable.
Mix
When the preparation instruction states 'mix' or 'mix thoroughly', then the following procedure is to be followed:
(1) For dry foods (such as bran) or semi-dry foods (such as cooked chopped meat):
- Form the food into a cone or pile.
- Flatten the cone slightly and separate into four equal segments.
- Pull the segments apart so that four separate piles are formed.
- Combine diagonally opposite piles and mix together thoroughly.
- This process should be repeated until thorough mixing of the group of purchases has been achieved.
(2) For foods containing juice such as tomatoes and oranges:
- If possible, the food being prepared should be chopped in a large glass or stainless steel bowl so that all the juice is collected.
- Mixing of the chopped pieces is then done in the bowl using gloved hands or stainless steel cutlery and should be mixed as thoroughly as possible.
- For the purposes of the ATDS, any juice must be regarded as an integral part of the food being prepared for analysis. A proportional amount of juice and seeds must therefore be included in the sample containers.
(3) For liquids such as milk and beer:
- Liquids are to be measured into a large receptacle such as bowl or jug made of stainless steel or Pyrex. Plastic containers are to be avoided.
- The total volume added to the jug or bowl should be thoroughly stirred with a stainless steel utensil before being poured into the sample containers.
GENERAL INSTRUCTIONS:
Gloves
Gloves are to be worn whenever the food being prepared could come into contact with hands.
The gloves to be used are Ansell rubber gloves not containing lubricant. Gloves will be provided by the State or Territory health departments.
Equipment
- Stainless steel knives
- Wooden cutting board (good quality, smooth, crack free)
- Wooden rolling pin for crushing foods.
- Stainless steel or teflon coated utensils (ie frypans, spatulas, etc.). Glass equipment can also be used provided it is Pyrex.
- For the purposes of mixing liquids, a large stainless steel or Pyrex receptacle such as a jug or bowl is to be used.
- Avoid ceramic or enamel ware to ensure traces of cadmium or lead are not leached into the sample.
- Plastic bags for enclosing sample containers.
Washing of Equipment
Equipment is to be washed using only the detergent endorsed by AGAL, which is Neutracon and the ATDS liaison officers should have ensured that supplies of this detergent are available.
HANDLING PURCHASES IN THE FOOD PREPARATION FACILITY:
Each purchase as provided by the purchasing officer should arrive in separate packaging. Fresh foods such as pears and chicken fillets will be in separate packages labelled with the name of the food and the date of purchase. Manufactured, packaged foods will be labelled clearly with the date of purchase. Purchases will be in either lots of four or lots of nine.
Keeping Samples Separate
In those cases where nine purchases have been made, care must be taken to ensure no mixing of any kind between the three groups of samples. This means careful cleaning of utensils between the three preparation procedures.
To ensure accuracy and to keep food samples separate, the procedure for preparing one sample in readiness for freezing, including labelling, should be completed and all utensils cleaned thoroughly before the preparation of the next sample is started.
Preparation Procedures
Where four purchases are provided, portions from each of these are mixed together and all utensils are thoroughly cleaned using the recommended detergent upon completion of the preparation.
