2 Breast Milk is Always Best It s the normal way to feed a baby and is important for baby s health. If you plan to use Formula consult your doctor or health worker for advice.

3 Formulating-What is Infant Formula Infant Formula is food for infants. It is the only recognised alternative to breast milk It should satisfy the nutritional requirement of infants. For young infants up to 6 months of age it will be the sole source of nutrition. As the child gets older would be part of a more diversified diet.

4 Formulating-Regulation In Australia it is set out in FSANZ standard In China it is defined by GB International standard from Codex Stan Many countries will have their own standard. As these standards are living documents that are subject to review which may take years to complete their tends to be differences.

5 The Point You need to know what standard you are formulating to comply with.

6 Formulating Standard *Adequate Intake 0 6 months + Energy Value Energy Contribution Min Max g/day kj/g kj % of Total g/100kj g/100kj g/100kj Fat % Omega LA ARA Omega ALA DHA Protein % Carbohydrate % 2.6 Water 700 Total 778 ml/day Total 2337 Calculated kj/l kj/l kj/l Energy *Adequate Intake values taken from Nutrient Reference Values for Australia and New Zealand. These values have been extrapolated from Breastmilk studies. + Energy value is taken from FSANZ standard 1.2.8

9 Formulating Standard Clause 23 Fat Can t contain MCT s (Fat containing predominantly C8:0 and C10:0 saturated fats) Except if naturally occurring in milk based ingredient or a processing aid used to prepare fat soluble vitamins Must contain LA between 9% and 26% of total fat Must contain ALA between 1.1% and 4% of total fat Ratio of LA:ALA between 5:1 and 15:1 May contain up to 2% of the total fat as Omega 6 LCPUFA of which up to half may be AA May contain up to 1% of the total fat as Omega 3 LCPUFA of which EPA must not be greater than DHA If LCPUFA is present the Omega 6 LCPUFA content cannot be less than the Omega 3 LCPUFA content. Trans fat must not exceed 4% of total fat. Erucic acid must not exceed 1% of total fat.

10 Formulating Oils Facts Product will contain 20 to 35% Fat Fat will have a high level of Linoleic Acid and a lower level of Alpha Linolenic Acid Fat will be low or have no trans fats or Erucic Acid MCT's LA ALA LA:ALA Erucic C8:0 C10:0 C18:2 C18:3 C22:1 Total Trans Anhydrous Milk Fat Canola Coconut Corn Palm Kernel Palm Olein Palm Stearine Soyabean Sunflower
