Our take
CleanPlate reviewShelf-stable silken tofu with soy protein added
Mori-Nu Extra Firm Silken Tofu lists water, soybeans, soy protein isolate, glucono-delta-lactone and calcium chloride. The pack is 308 g and the panel is a US Nutrition Facts panel per 85 g, converted here to per 100 g.
CleanPlate scores it BA1. The B for nutrition reflects 8.24 g protein and natural iron and calcium per 100 g. The A for ingredients reflects whole or lightly processed ingredients (led by soybeans and soy protein isolate), with additives that cost points: calcium chloride. The 1 for risk is low: sodium, free sugar and saturated fat are all modest (sodium 47.1 mg, free sugar 0 g, saturated fat 0 g per 100 g).
Claims vs reality
What the pack says, checked against the ingredient list and nutrition panel.
- On the packPartly true
“28 g of protein per package”
The panel's 7 g per 85 g gives about 25 g across the 308 g pack; US rounding can lift it a little, but 28 g is at the top of that range.
- On the packHolds
“Low in Sodium”
47 mg per 100 g is under the 120 mg low line.
- On the packHolds
“Low-Fat”
1.8 g per 100 g is under the 3 g line.

A closer look
Does the label add up?
Water, soybeans, soy protein isolate, glucono-delta-lactone and calcium chloride.
Per 100 g: 58.8 kcal, 1.76 g fat of which 0 g saturated, 8.24 g protein, 47.1 mg sodium. The US panel prints rounded values per 85 g; fibre and total sugar are given as under 1 g and are not stored, so the score is provisional on missing lines. Calcium chloride (INS 509) costs 2 additive points; glucono-delta-lactone is a coagulant and is not scored. No percentages are printed, so soybeans are taken as about 22% of the pack (which gives the 8.2 g of protein) and the isolate as about 1%.
Ingredients to watch
- Added isolateWorth watching
Soy protein isolate adds protein to the soybean base and sits in the lowest ingredient tier.
- Panel roundingWorth watching
Values are US-rounded per 85 g, so fibre and sugar are not on record.
- Risk nutrientsFine
Sodium 47 mg, sugar 0 g added and no saturated fat per 100 g.
- ProteinFine
8.2 g per 100 g at 59 kcal.

Myth: "Silken tofu has the protein of firm tofu"
It holds 8.2 g per 100 g, about half of a pressed firm block.
Myth: "Shelf-stable means preservatives"
