# Infant Formula (0–6 months) — Manufacturing Specification, NOT a Recipe

**Status:** Design *specification* for issue to a licensed contract manufacturer. This document deliberately does **not** provide an exact ingredient recipe that someone could manufacture or feed experimentally.

**Breast milk is unequivocally first-best.** WHO/UNICEF recommend exclusive breastfeeding to 6 months. This spec exists only for the case where breastfeeding is not possible, and only as a brief to an **established, licensed infant-formula manufacturer** — never as a home or informal production guide. A South African study found home-prepared replacement milks failed to meet all infant micronutrient and essential-fat requirements, and powdered formula is not sterile.

Reference standard: **Codex CXS 72-1981** (Standard for Infant Formula) in full, plus **SA Regulation R991 of 2012**.

## 1. Nutritional design target (prepared product)

| Per 100 kcal | Proposed target | Codex permitted range |
|---|---|---|
| Protein, cow-milk based | 2.1 g | 1.8–3.0 g |
| Fat | 5.2 g | 4.4–6.0 g |
| Available carbohydrate | 11.2 g | 9–14 g |
| Linoleic acid (LA) | Optimised by oil assay | Minimum 300 mg |
| Alpha-linolenic acid (ALA) | Optimised by oil assay | Minimum 50 mg |
| LA:ALA ratio | 8–12:1 | 5–15:1 |

**Prepared energy density:** ~67 kcal/100 ml.

**Approximate powder specification** (exact scoop and dilution to be set by bulk-density and osmolality testing): ~**500–510 kcal, 10.5 g protein, 26 g fat, 57 g carbohydrate per 100 g**, reconstituted at ~13.2 g powder per 100 ml prepared feed.

The **full** vitamin, mineral, choline, myo-inositol, L-carnitine and amino-acid specification must meet the complete Codex table — not merely the macronutrients above. Osmolality and potential renal solute load must be **calculated and verified** (target osmolality < ~450 mOsm/kg H₂O), not deferred.

## 2. Ingredient architecture (specification, not quantities)

- **Carbohydrate:** lactose as the main carbohydrate; **no added fructose or ordinary sucrose.**
- **Protein:** skim milk powder + demineralised whey, blended to the required protein level and a whey:casein ratio approximating human milk (~60:40), meeting the Codex amino-acid scoring pattern.
- **Fat:** canola, high-oleic sunflower, standard sunflower and an appropriate saturated-fat source, **optimised from actual fatty-acid certificates** to hit LA, ALA and the LA:ALA window.
- **Micronutrients:** infant-grade vitamin and mineral premixes (never hand-dosed).
- **Conditionally essential:** choline, myo-inositol, L-carnitine — all present and quantified.
- **DHA / ARA:** only if both affordability and stability permit. If DHA is used, Codex says **ARA should be at least the same concentration.**
- **No soya "cheap formula" as default.** Codex requires a higher protein minimum for soy-isolate formula, and **SA R991 permits only soya isolate — not ordinary soya flour.** A plant formula is an exception (e.g. galactosaemia / documented cow-milk-protein indication), not a cost measure.

## 3. The non-negotiable safety model

- Dedicated infant-formula production line with **spray drying**.
- Environmental ***Cronobacter sakazakii*** control and ***Salmonella*** control.
- Batch release on assay; full **traceability** and **recall capability**; validated shelf life with vitamin overages set by measurement.
- Heavy-metal testing (Pb, As, Cd, Hg) and aflatoxin M1 control on dairy inputs.
- **Preparation guidance (SA IMCI):** reconstitute with boiled water still **hot enough to kill organisms in the powder**, single-feed preparation, cup feeding, discard leftovers within two hours.
- **R991 marketing constraints:** restricts promotion; mandates Codex compliance, specific warnings and multilingual information. This is a **clinic / procurement product**, not a fashionable "smart food."

## 4. Real-world intervention reality

Budget formula already sells at roughly **R287 / 1.8 kg (~R159/kg)**. At the Codex planning assumption of ~750 ml prepared formula/day, an exclusively formula-fed infant needs roughly **3 kg powder per month**. The real intervention therefore requires **guaranteed monthly supply and clean-water support** — not merely a cheaper tin.

> **Cutting ingredients or quality control in infant formula is the one place where "poorest possible price" can become lethal.** Ship this last, and only through an existing licensed manufacturer.
