Turning the range into a date

Amaranth (whole grain) keeps 4 months in the pantry. Each kind gets its own dated rows here, 4 rows across the 2 the USDA lists under this name, because a date is only worth printing against the window it belongs to.

The USDA rates 2 kinds of this separately

Amaranth, flour, meal keeps 2 months, which is shorter than the window this page answers with. The USDA files 2 separate entries under this name — whole grain and flour, meal — and they do not keep for the same time: Amaranth, flour, meal holds 2 months outside the freezer, Amaranth, whole grain holds 4 months.

The freezer helps less here than you would expect

The freezer buys less here than its reputation suggests: 2 times what the pantry gives, 4 months against 8 months, both still measured in months. For this item freezing is an extension rather than a different way of keeping it. On the same shelf it sits 15 of 23, between Spelt at 6 months and Oats at 4 months. Whole grain, grain and flour are the same food in the source list.

Every storage figure the USDA publishes for this item

An unusual pairing: the USDA rates the pantry and the freezer for this item but skips the refrigerator entirely, one of 126 foods of the 466 that get no refrigerator time. The source also indexes it as whole grain, grain, flour and meal.

Can you freeze amaranth?

Yes. The USDA gives amaranth (whole grain) 8 months in the freezer, and held at 0 °F food stays safe beyond that: the figure is about quality. Shelf-stable food gains little from freezing; keep it dry, sealed and away from heat instead.

How to tell if amaranth has gone bad

Go by the date first: amaranth keeps 4 months in the pantry. Insects, a musty or rancid smell, clumping from damp, or a swollen can mean it goes out. Any dish you cook with it follows the 2-hour rule, 1 hour above 90 °F.

Is it still safe to eat, or just past its best?

The answer at the top of this page reads 4 months in the pantry. The USDA rating this place at all is the USDA saying Amaranth, whole grain keeps there, so the figure rates how good it will be. Past it, whether it has gone bad is yours to judge by look and smell: this window rates quality, not the day it turns hazardous.

It is past the date. Now what?

Say the calculator above puts Amaranth, whole grain past its 4 months in the pantry window. Past that the calendar stops deciding and the food itself does. Insects or webbing in the package, a musty or rancid smell, or clumping that says damp got in mean it goes out whatever the date says.

The whole rule, including the cases the source does not cover, is set out under what to do when the date has passed.

Where these numbers come from

Every storage time on this page is the USDA’s own published figure from the FoodKeeper data, one of the 9 it keeps per food, reproduced unchanged and never an estimate of ours. Where the USDA lists several kinds under one name, each kind keeps its own windows, and the page names the kind its answer is for. The dates and multipliers are ours, computed from those ranges.

Comparisons and the place in the category are computed for Amaranth, whole grain, which is the kind the plain name means here, chosen kind by kind rather than by the order the source happens to list them in.
