How long doesRe-hydrated textured soy proteinlast in the fridge?
The methods the USDA actually rates for this item
The USDA rates only 2 of its nine storage methods for this item, and the pantry from the day of purchase and refrigerator are what it rates. The other 7 slots are blank, and a blank is not a zero: it means no published figure, not that the method fails.
Every storage figure the USDA publishes for this item
The USDA gives this item a pantry and a refrigerator figure and no freezer figure at all, the pattern behind 79 of the 466 foods in the data.
- Unopened · in the pantry3 months to 4 months
- In the fridge3 days to 4 days
What the USDA adds in words
The USDA attaches 1 handling note to this item, reproduced below word for word. It is not a storage time: it qualifies the figure above rather than replacing it. These are the source's own sentences, not ours, and they are the part of the FoodKeeper record that a table of durations cannot carry.
In the refrigerator. Refrigeration time applies to prepared product.
Turning the range into a date
Counting 4 months forward from a date is not arithmetic anyone does reliably in their head. Give the field the day it went into storage.

- In the fridgeUse by3 days to 4 days after the day you stored it
Is this window about safety or about taste?
The answer at the top of this page reads 3 days to 4 days in the fridge. What decides that is the record's own note: this figure is for the product after cooking, which is cooked and still moist. Past it, throw it out rather than taste it: a perishable food can carry enough bacteria to make you ill while it still looks and smells fine.
The figure in the pantry here is a quality window. The same page carries windows of more than one kind, so which sentence applies depends on which row you are reading, not on the food. Every figure assumes the food was sound when you stored it, that your refrigerator holds 40 °F or below and your freezer 0 °F or below, and that the package was handled normally.
It is past the date. Now what?
Say the calculator above puts Re-hydrated textured soy protein, (TSP) past its 3 days to 4 days in the fridge window, or the container sat out on the counter overnight. Throw the container out without tasting it, and count any hours it already spent out of the refrigerator as part of that window rather than on top of it.
The USDA's limit for perishable food standing at room temperature is 2 hours, or 1 hour when the kitchen is above 90 °F, and that clock runs whatever the storage figure says. The FoodKeeper entry this page is built from prints storage times and nothing else, so anything past them here is USDA and FSIS guidance rather than a figure from the source. The whole rule, including the cases the source does not cover, is set out under what to do when the date has passed.
Is that a long time?
Among the 5 items the USDA files under Vegetarian Proteins, this item ranks 4 by how long it keeps outside the freezer. Soy flour, full-fat holds 6 months, Tofu holds 1 week. Among the 340 foods the USDA also gives a refrigerator figure, it keeps longer than 16% of them.
Items that behave the same way
The 4 items below are the closest match to this item by storage behavior, running 1 week to 2 years and bracketing its 4 months.
Products the USDA rates in the same places
Only 1 other product in the whole file carries the same set of rated places as this one, pantry from the day of purchase and refrigerator: Dry gravy mixes. That is 1 product out of 466, which makes this a rare shape of record rather than a common one, and it is worth knowing that the comparison below is drawn from a very small group. Of the 1 shown, 1 keeps longer than this one. The longest-keeping of them is Dry gravy mixes at 2 years.

Closest by shape, but not an exact match — they share most of these places, not all of them.

- Textured soy protein3 months in the pantry once openedup to 2 years sealed in the pantry
- Tofu1 week sealed in the fridge
- Miso1 year sealed in the fridge
The rest of the Vegetarian Proteins shelf
Vegetarian Proteins is a short shelf: 4 products besides this one. They run from Textured soy protein at 2 years down to Tofu at 1 week, and this product sits with 3 products above it. A shelf this small is worth reading whole, which is why every one of them is printed below rather than a sample. Across the whole of Vegetarian Proteins the same product ranks 4 of 5. The middle of the shelf is Soy flour, at 6 months. The freezer is left out of the order on purpose: it flattens almost everything it touches.

If it has to keep longer than this
If it has to keep longer than 4 months, Vegetarian Proteins offers 2 products that hold at least twice as long outside the freezer. The nearest step up is Miso at 1 year against this one's 4 months, and the rest are Textured soy protein. A short list like this one is itself the finding: the category has few longer options. In the other direction, 1 entry in the category keeps half as long or less, Tofu among them. The largest step the category offers is Textured soy protein at 2 years.

The record this page is built from
This page is built from a single FoodKeeper row, record 172 — the source’s own number for it, not a position — one of the 661 rows in the snapshot. That row fills 2 of the nine storage slots with a time, and the binding figure on it is printed by the source in months, which is the unit this page keeps rather than converting it to days. The record carries 1 handling note, quoted on this page word for word. Every figure here comes from one fixed snapshot, USDA FoodKeeper, retrieved 1 September 2026, and is not refreshed page by page.
Where these numbers come from
Every range on this page is published by the USDA FoodKeeper and reproduced unchanged. The multipliers, the rankings, the percentages and the dates are ours, computed from those ranges. Where the source gives a span such as 3 to 5 weeks, comparisons use the upper figure, and the full span is always printed.
Rankings cover only the items the USDA gives a usable figure for, and identical ranges share a place rather than being ordered arbitrarily. Neighbors are chosen by nearest storage time within the same category, never alphabetically: two foods filed next to each other by name usually have nothing to do with each other. The freezer is excluded from ranking because it flattens almost everything.
Where the USDA lists several kinds under one name, they share one page here and every kind keeps its own windows: the source prints them as separate rows, and a page that merged them would be inventing a figure the source never published. Comparisons and the place in the category are computed for the kind the plain name means — the shell egg for eggs, the can for tuna — which is settled name by name rather than by the order the source lists its rows in, and the page names it. Where the plain name means no single kind, the page prints no single figure at all and lists the kinds instead.
