Question 1

Does whole milk yogurt sweeten gelato?

Accepted Answer

Barely. Its only sugar is lactose, about 4.7 g per 100 g, with a POD near 16 versus sucrose's 100. It adds almost no perceived sweetness, so it is counted within milk solids-not-fat rather than the sugar blend. You still add sucrose, dextrose or other sugars to reach your target sweetness.

Question 2

How does yogurt affect PAC and freezing point?

Accepted Answer

Its lactose gives a PAC of roughly 4.5 per 100 g of product, a modest amount. Yogurt alone will not soften gelato much, so build most of your PAC with dextrose, invert sugar or glucose syrups and treat yogurt mainly as a flavor and dairy-solids source.

Question 3

Why does frozen yogurt taste tart?

Accepted Answer

Fermentation converts some lactose into lactic acid, dropping the pH to around 4.4. That acidity is the signature tang. Because heat plus high acidity can curdle milk proteins, pasteurise the rest of the base first, then blend the yogurt in cold to protect texture and flavor.

Question 4

Can I replace all the milk with whole milk yogurt?

Accepted Answer

You can, but acidity and tang intensify. Yogurt carries fat and milk solids similar to whole milk, so texture stays close, yet the sour note grows strong. For a milder frozen yogurt, blend yogurt with milk or cream instead of using it as the sole dairy.

Question 5

Is this the same as Greek yogurt for balancing?

Accepted Answer

No. Greek yogurt is strained, roughly doubling protein and total solids while lowering lactose, giving a denser body and even less sweetness. These figures are for standard unstrained whole-milk yogurt; use a separate, higher-solids entry when balancing with Greek yogurt.

Parameter	Value	What it means
Total Solids	12.1%	Everything that isn't water — the backbone of body and scoopability.
Water	87.9%	Free water that will freeze; drives ice-crystal size.
Sugars	0%	Total sugars, the source of sweetness and freezing-point depression.
Fat	3.25%	Carries flavor and gives a rounder, warmer mouthfeel.
MSNF	8.85%	Milk solids-non-fat: proteins and lactose that stabilize structure.
Protein	3.47%	Binds water and helps whip in air.
POD (sweetening power)	0.75	Relative sweetness vs sucrose = 100.
PAC (anti-freezing power)	4.66	Freezing-point depression vs sucrose = 100 — controls how soft it scoops.
