question: Why don’t nuts seem to go bad like other food? (mold, fungus, etc.)
comment: Nuts do have a lifespan. I will provide a link at the end that gives you average life spans of nuts but lets stick with pecans for now. Unshelled pecans can last up to 2 years if frozen and 9 months if refrigerated (which its recommended to refrigerate pecans). Shelled pecans will last 9-12 months if frozen and about 6 months if refrigerated. General signs of expiry; they look dried up, discolored, smell rancid or like used cooking oil and a bitter or stale taste. Its not necessarily unsafe to eat rancid pecans (any mold present may make you want to reconsider) however they will have less nutritional value and won't taste anywhere near as good a fresh ones. In your case it may just be that they were stored under the right conditions that most of the above symptoms have been reduced (i'm speculating though). I would say if you got a fresh bag of pecans and A/B'd them you would see a significant difference in taste and quality. Link for other nuts references: [ URL_0 ]( URL_0 )
passages: Nuts are the source of energy and nutrients for the new plant. They contain a relatively large quantity of calories, essential unsaturated and monounsaturated fats including linoleic acid and linolenic acid, vitamins, and essential amino acids. Many nuts are good sources of vitamin E, vitamin B, folate, fiber, and the essential minerals magnesium, phosphorus, potassium, copper, and selenium. Nuts are most healthy in their raw unroasted form because roasting can significantly damage and destroy fats during the process. 
  
  This table lists the percentage of various nutrients in four unroasted seeds. 
  
  Section::::Research.
   The seeds should be cleaned of any additional material (fruit pulp, leaf and seed-pod fragments, cone scales, etc.), but the shells of nuts should not be removed.
  
  Section::::Warm and cold stratification.
   There are two different ways the nuts can be processed. The first is dry roasting, where heat is applied indirectly to the products. It is important that the nuts or seeds are stirred constantly to avoid over- and under-cooking. This method requires no additional ingredients. The second is oil frying, where the nuts go into preheated oil for a certain amount of time. There are various oil roasting methods from continuous, batch and curtain fryers. The ultimate impact on the nuts can vary; both methods are recommended by studies.

  Section::::Regulations.:United States.
   Premature nut fall occurs when infection takes place before the formation and hardening of the shell tissue and is able to rot and shrivel the kernel. The tree then sheds the diseased nut.

   Section::::Prevention.:Cross-reactivity.
   Section::::Health.:Food contamination.
  
  Fungal infestation can spoil stored cereals, seeds, fruits, nuts, cocoa beans, and raw sugar. Infestation causes discoloration, loss of germinability, heating, mustiness, and decay. The consequences are less worth of products and combustion. For example, coffee produced from moldy coffee beans lack aroma and flavor. Seeds and nuts are extracted to produce vegetable oils. However,"A. penicillioides" can increase free fatty acid content in the oil and produce bad taste. The fungus growing on raw sugar can also invert sugar, which reduces sucrose and increases invert content.
   Additionally, growth and yield are also limited by zinc and boron deficiencies in the soil. Boron-rich soil resulted in an increase of chickpea yield and size, while soil fertilization with zinc seemed to have no apparent effect on the chickpea yield.
  
  Section::::Pathogens.
  
  Pathogens in chickpeas are the main cause for yield loss (up to 90%). One example is the fungus "Fusarium oxysporum f.sp. ciceris", present in most of the major pulse crop-growing areas and causing regular yield damages between 10 and 15%.
   As with many Fagaceae, the nuts of many "Castanopsis" species are edible. The trees may be grown for their nuts, but more often they are used as forestry or ornamental trees and the nuts are collected opportunistically. Among many animals, such as tits, corvids, rodents, deer and pigs, the nuts are popular as food too.
   Nuts are under preliminary research to assess whether their consumption may lower risk for some diseases, such as cardiovascular diseases and cancer.
  
  Nuts have a low glycemic index (GI) due to their high unsaturated fat and protein content and relatively low carbohydrate content.
  
  Section::::Other uses.
   As a legume, the peanut belongs to the botanical family Fabaceae; this is also known as Leguminosae, and commonly known as the "bean," or "pea," family. Like most other legumes, peanuts harbor symbiotic nitrogen-fixing bacteria in root nodules. This capacity to fix nitrogen means peanuts require less nitrogen-containing fertilizer and also improve soil fertility, making them valuable in crop rotations.
   Some raw pine nuts can cause taste disturbances, lasting from a few days to a few weeks after consumption. A bitter, metallic, unpleasant taste is reported. There are no known lasting effects, with the FDA reporting that there are "no apparent adverse clinical side effects". Raw nuts from "Pinus armandii", mainly in China, may be the cause of the problem. Metallic taste disturbance is typically reported 1–3 days after ingestion, being worse on day two and typically lasting up to two weeks. Cases are self-limited and resolve without treatment.
  
  Section::::Other uses.
   Almonds are susceptible to aflatoxin-producing molds. Aflatoxins are potent carcinogenic chemicals produced by molds such as "Aspergillus flavus" and "Aspergillus parasiticus". The mold contamination may occur from soil, previously infested almonds, and almond pests such as navel-orange worm. High levels of mold growth typically appear as gray to black filament like growth. It is unsafe to eat mold infected tree nuts.
   Modifying words like "fancy" or "choice" have not historically carried any legal meaning in the United States, and they remain absent from the current regulations. In a 1915 federal case against "fancy mixed nuts" that were argued by competitors to be an inferior grade, "U. S. v. 25 Bags of Nuts," N. J. No. 4329 (1915), the court declined to accept a trade standard. The ruling said
  
  Section::::Nutritional Benefits.
  
  BULLET::::- A Harvard University Professor of Nutrition and Epidemiology, Dr. Frank Hu, reports that recent studies found daily nut-eaters were less likely to die of cancer, heart disease and respiratory disease.
   Possums also eat the nuts, as do rodents such as squirrel-toothed rats ("Anisomys imitator"), eastern white-eared giant rats ("Hyomys goliath"), Rothschild's woolly rats ("Mallomys rothschildi"), and giant naked-tailed rats ("Uromys anak"). Growers will put platforms or other obstacles on the trunks of trees to keep the pests out.
  
  Harvested nuts are often beset by rats and cockroaches. Hanging nuts in the smoky areas above fires can prevent this, but after a while the taste of the nuts is affected.
  
  Section::::Use by humans.
   Kola nuts can be harvested mechanically or by hand, by plucking them at the tree branch. When kept in a cool, dry place, kola nuts can be stored for a long time.
  
  Section::::Cultivation.:Pests and diseases.
   Nuts are an important source of nutrients for both humans and wildlife. Because nuts generally have a high oil content, they are a highly prized food and energy source. A large number of seeds are edible by humans and used in cooking, eaten raw, sprouted, or roasted as a snack food, or pressed for oil that is used in cookery and cosmetics.
  
  Nuts used for food, whether true nut or not, are among the most common food allergens.
  
  Some fruits and seeds that do not meet the botanical definition but are nuts in the culinary sense are:
   The nuts are subject to attack by the kola weevil "Balanogastris cola". The larvae of the moth "Characoma strictigrapta" that also attacks cacao bore into the nuts. Traders sometimes apply an extract of the bark of "Rauvolfia vomitoria" or the pulverised fruits of "Xylopia" and "Capsicum" to counteract the attack on nursery plants. The cacao pests "Sahlbergella" spp. have been found also on "C. nitida" as an alternative host plant. While seeds are liable to worm attack, the wood is subject to borer attack.
  
  Section::::Chemical composition.
  
  Preliminary studies of phytochemicals in kola nut indicate the presence of various constituents:
   Nitrogen nutrition is another factor that affects the yield of "Cicer arietinum", although the application itself differs from other perennial crops with regards to the levels administered on the plant. High doses of nitrogen inhibit the yield of the chickpea plant. Drought stress is a likely factor that also inhibits the uptake of nitrogen and subsequent fixation in the roots of "Cicer arietinum". The growth of the perennial chickpea is dependent on the balance between nitrogen fixation and assimilation that is also characteristic of many other agricultural plant types. The influence of drought stress, sowing date, and mineral nitrogen supply all have an effect on the yield and size of the plant, with trials showing that "Cicer arietinum" differed from other plant species in its capacity to assimilate mineral nitrogen supply from soil during drought stress. Additional minerals and micronutrients make the absorption process of nitrogen and phosphorus more available. Inorganic phosphate ions are generally attracted towards charged minerals such as iron and aluminium oxides.
   The ideal temperature for longest possible storage of walnuts is in the and low humidity – for industrial and home storage. However, such refrigeration technologies are unavailable in developing countries where walnuts are produced in large quantities; there, walnuts are best stored below and low humidity. Temperatures above , and humidities above 70 percent can lead to rapid and high spoilage losses. Above 75 percent humidity threshold, fungal molds that release dangerous aflatoxin can form.

   Peanuts are legumes, not true nuts, but they share with true nuts the risk of causing allergic reactions, even in minute amounts. Pure peanut and nut-derived oils are not usually allergenic (as they do not typically contain the proteinaceous part of the plant), but avoiding them may be safer, as serious peanut and nut allergy is widespread, oil purity cannot be guaranteed, and other hypoallergenic oils are easily substituted.
   Management is by avoiding eating the causal nuts or foods that contain them among their ingredients, and a prompt treatment if there is an accidental ingestion. Total avoidance is complicated because the declaration of the presence of trace amounts of allergens in foods is not mandatory in any country, with the exception of Brazil.
  
  Tree nut allergies are distinct from peanut allergy, as peanuts are legumes, whereas a tree nut is a hard-shelled nut.
  
  Section::::Signs and symptoms.
   The belaying pins and deadeyes aboard USS "Constitution" and many other sailing ships were made from lignum vitae. Due to its density and natural oils, they rarely require replacement, despite the severity of typical marine weathering conditions, and also resisted jamming in their mortise holes. The sheaves of blocks on sailing vessels were made of lignum vitae until the introduction of modern synthetics.
   Prevention involves an exclusion diet and vigilant avoidance of foods that may be contaminated with tree nuts, nut particles, or oils extracted from nuts. In the United States, the federal Food Allergen Labeling and Consumer Protection Act (FALCPA) requires that any packaged food product that contains tree nuts as an ingredient must list the specific tree nut on the label. Foods that almost always contain tree nuts include pesto, marzipan, Nutella, baklava, pralines, nougat, gianduja, and turrón. Other common foods that may contain tree nuts include cereals, crackers, cookies, baked goods, candy, chocolates, energy/granola bars, flavored coffee, frozen desserts, marinades, barbecue sauces, and some cold cuts, such as mortadella. Tree nut oils (especially shea nut) are also sometimes used in lotions and soaps. Asian and African restaurants, ice cream parlors, and bakeries are considered high-risk for people with tree nut allergy due to the common use of nuts and the possibility of cross contamination.
