Dairy forms the foundation of most frozen desserts. Understanding dairy composition enables precise formulation.

Milk Solids Non-Fat (MSNF) consists of:
| Component | % of MSNF | Function |
|---|
| Lactose | 54% | Mild sweetness, PAC contribution |
| Protein (casein + whey) | 37% | Emulsification, body, mouthfeel |
| Minerals | 9% | Flavor, structure |
| Product | Target Fat % | Notes |
|---|
| Gelato | 4–8% | Dense, intense flavor |
| Premium ice cream | 14–18% | Rich, creamy |
| Standard ice cream | 10–14% | Balanced |
| Light ice cream | 6–10% | Reduced calorie |
| Sorbet | 0% | Dairy-free |
Total Fat = Σ(ingredient_weight × fat_%) / total_base_weight × 100
Rich custard gelato base:
| Ingredient | Weight | Fat % | Fat Contribution |
|---|
| Whole milk | 500g | 3.5% | 17.5g |
| Heavy cream | 150g | 36% | 54g |
| Egg yolks | 100g | 30% | 30g |
| Sugar | 140g | 0% | 0g |
| Skim milk powder | 25g | 1% | 0.25g |
| Total | 915g | — | 101.75g |
Fat % = 101.75 / 915 × 100 = 11.1%
| Product | Target MSNF % | Notes |
|---|
| Gelato | 8–11% | Higher body |
| Premium ice cream | 9–11% | Balanced |
| Standard ice cream | 10–12% | Good body |
| Economy ice cream | 11–14% | Maximum legal limit |
Total MSNF = Σ(ingredient_weight × MSNF_%) / total_base_weight × 100
Same rich custard gelato base:
| Ingredient | Weight | MSNF % | MSNF Contribution |
|---|
| Whole milk | 500g | 8.5% | 42.5g |
| Heavy cream | 150g | 5.5% | 8.25g |
| Egg yolks | 100g | 0% | 0g |
| Sugar | 140g | 0% | 0g |
| Skim milk powder | 25g | 97% | 24.25g |
| Total | 915g | — | 75g |
MSNF % = 75 / 915 × 100 = 8.2%
This is slightly low; add more skim milk powder to reach 10%.
| Product | Target TS % | Notes |
|---|
| Gelato | 36–40% | Dense texture |
| Premium ice cream | 38–42% | Rich body |
| Standard ice cream | 36–40% | Balanced |
| Sorbet | 28–32% | Lighter |
TS = Fat + MSNF + Sugar + Other Solids
- Increases MSNF without adding water
- Improves body and texture
- Enhances protein for emulsification
- Binds free water
| Component | % |
|---|
| Protein | 35–37 |
| Lactose | 50–52 |
| Fat | 0.5–1.5 |
| Minerals | 8–9 |
| Moisture | 3–4 |
| Application | Dose (% of base) | Notes |
|---|
| MSNF boost | 2–4% | Standard use |
| Body improvement | 3–5% | Noticeable texture change |
| Maximum practical | 6–8% | Risk of sandiness |
| Have | Need | Conversion |
|---|
| 36% cream | 40% cream | Add butter or reduce slightly |
| 40% cream | 36% cream | Add 10% whole milk |
| 30% cream | 36% cream | Add butter (calculate) |
| Heavy cream | Whipping cream | Use as-is (minor difference) |
To increase fat content:
Butter needed = (target_fat - current_fat) × base_weight / 80
(Butter is ~80% fat)
| Alternative | Fat % | Notes |
|---|
| Coconut cream | 20–25 | Best fat substitute |
| Coconut milk (full fat) | 15–18 | Good body |
| Oat milk | 2–3 | Creamy mouthfeel |
| Soy milk | 3–4 | Good protein |
| Almond milk | 2–3 | Thin; needs thickening |
| Cashew milk | 2–4 | Neutral, creamy |
| Challenge | Solution |
|---|
| Low fat | Use coconut cream; add coconut oil |
| Thin body | Add stabilizers; use higher-fat options |
| Missing MSNF | Add soluble fiber (inulin) |
| Weak emulsion | Add soy lecithin |
| Product | Fat % | MSNF % | Acidity |
