Nuts: Because they are loaded with oil, they tend to go rancid fairly quickly.

Fresh products like bacon or nondried pancetta go rancid much more quickly and should be checked carefully.
|
|
Because they have less fat than pecans or peanuts, they are not likely to go rancid, though they are best kept in the freezer.

If you prefer to use lard, Burn cautions to wipe off any excess on the surface so it doesn't go rancid in your cabinet.

Schaich observes how common foods like tortilla chips and peanut butter go rancid, and believes she's found processes that cause food to spoil faster than we think.

Anyone who has seen Steve's videos knows that the fats and shortening in everything from biscuits to candies is likely to go rancid, and 70-year old rancid fats are considerably less palatable than spoiled milk.

Much of it is what he calls "stripped carbs," or rice, wheat and oats from which manufacturers have removed the germ and bran because the oils in them would go rancid sitting for months on the grocery shelves.

The peanut butter rubbed off, doing damage to soft furnishings and other peoples' costumes, and then began to go rancid under the heat of the lighting. Food, odious, and messy substances were banned as costume elements after that event.

Infused oils are also used for seasoning. There are two methods for doing an infusion—hot and cold. Olive oil makes a good infusion base for some herbs, but tends to go rancid more quickly than other oils. Infused oils should be kept refrigerated.

Alternatively, one may also use a food-grade drying oil such as poppyseed oil, tung oil or linseed oil. The first two dry much faster than linseed. Note, plant based oils will go rancid, and cause wood cutting boards to pick up unpleasant smells. Most commercially available linseed and tung oils are not “food grade”, as they contain metallic driers.

In general, edible savory vegetable or olive oils are not recommended because they tend to go rancid, causing the board to smell and food to pick up the rancid taste. When heavily or deeply scored, wooden boards need to be resurfaced as scoring can harbour bacteria. Boards can be easily resurfaced with various woodworking tools, such as scrapers or planes, even sandpaper.

Soup was made in the usual way, reduced, degreased—or the fat would go rancid—and then reduced repeatedly until it took on the consistency of jelly. Once it was sufficiently gelatinous to hold its form, it was placed on pieces of flannel or unglazed earthenware dishes and rotated regularly to dry it further. This was a seasonal process attempted only in the winter when humidity was low. Once dry, it was wrapped in paper and stored in boxes.

Sibley, with no marketable skills, is drafted into the Plutonian army, which is building an anomalously large war machine. His new commanding persona makes him swiftly rise in rank, and he soon concludes that Pluto intends to invade and plunder its neglectful mother planet. Instead, Doncaster suddenly reveals that the Pluto colony was created by them as a stepping-stone to the stars, and that Earth will be left to go rancid, while "new men", like the rebuilt Sibley, conquer the universe.

Randolph B. Marcy, an Army officer who wrote an 1859 guide, advised taking less bacon than the earlier guides had recommended. He advised emigrants to drive cattle instead as a source of fresh beef. Marcy also instructed emigrants to store sides of bacon in canvas bags or in boxes surrounded by bran to protect against extreme heat, which could make bacon go rancid. Marcy instructed emigrants to put salt pork on the bottom of wagons to avoid exposure to extreme heat.

The oat, like other cereals, has a hard, inedible outer husk that must be removed before the grain can be eaten. After the outer husk (or chaff) has been removed from the still bran-covered oat grains, the remainder is called oat groats. Since the bran layer, though nutritious, makes the grains tough to chew and contains an enzyme that can cause the oats to go rancid, raw oat groats are often further steam-treated to soften them for a quicker cooking time (modern "quick oats") and to denature the enzymes for a longer shelf life.

A 100-gram portion of ground flaxseed supplies about , 41 g of fat, 28 g of fiber, and 20 g of protein. Whole flaxseeds are chemically stable, but ground flaxseed meal, because of oxidation, may go rancid when left exposed to air at room temperature in as little as one week. Refrigeration and storage in sealed containers will keep ground flaxseed meal for a longer period before it turns rancid. Under conditions similar to those found in commercial bakeries, trained sensory panelists could not detect differences between bread made with freshly ground flaxseed and bread made with flaxseed that had been milled four months earlier and stored at room temperature.
