FAQ

Which sous-vide temperature minimizes yield loss for Sodium Alginate Spherification Calculator?

Below 60°C the muscle proteins (myosin, actin) denature gradually, retaining moisture. Yield loss grows from ~8% at 54°C to ~22% at 65°C on lean cuts. Target medium-rare or lower for tender cuts like tenderloin and ribeye to maximize yield.

How long until the core reaches the target temperature?

This calculator uses Baldwin's heat-diffusion estimate: 36–48 seconds per millimeter of thickness for slab-shaped proteins. For pork, chicken and egg, FDA 7-log pasteurization minutes are added on top of the core-reach time.

What is the standard hydrocolloid ratio for molecular gastronomy?

Xanthan gum 0.3–0.7%, sodium alginate 0.5%, agar agar 1.0%, methylcellulose 1.5% — all by weight of the base liquid. The calculator outputs grams in 0.1 g resolution, ready for professional kitchen scales.
