Storage of all forms of almond in cool and dry conditions (Maintaining almond quality during long-term storage under ambient conditions is a challenge in emerging export markets, such as China, which may have highly variable temperatures and relative humidities, depending on season and region). A long-term storage study published in the Journal of Food Science evaluated the quality of shelf life of almonds, raw kernels, blanched kernels, and blanched sliced kernels stored for at least 18 months under controlled (including abusive) environmental conditions.
A shelving study conducted by Natick researchers from the United States Army demonstrated that various forms of almonds (raw, roasted, scalded or sliced) can have a three-year shelf life when packaged in optimal packaging (vacuum-sealed trilaminated aluminum bags). The almonds are handed over to the handler for sizing, sorting and sorting, and then stored in containers or other bulk containers under controlled conditions before shipping or further processing. For container shipments to foreign markets, shell almonds are usually packaged in bags. Almonds without shells are naturally packaged in cardboard boxes or fiber containers in bulk, depending on the product and volume.
Sliced almonds and roasted almonds require more protection against moisture and oxygen. Starting with raw almonds, they can last fresh for up to a year or even longer if stored properly. . They should last more or less 2 to 4 weeks after the expiration date.
Shelled almonds come with an expiration date. When they are not open, they can stay in the pantry for 4 months. If you open them, you should refrigerate them to last for about 8 months. If you want them to last even longer, freeze them and they will take 10 months.
raw almonds will stay fresh for at least one year and up to 2 years at most. Unopened snack almonds will retain their quality for at least one week after the expiration date. Once opened, deterioration accelerates, so it's best not to store it for extended periods of time. When it's time to prepare shelled almonds for eating, it's OK to look for ways to use the shells.
After reading the previous section, you already know that almonds usually maintain a reasonably good quality for much longer than the printed date suggests. In fact, most people who hate almonds have probably spoiled them for the first time and may have eaten them. To tell you the truth, it is difficult to say precisely how long almonds last, since the recommendations are a bit exaggerated. Roasted almonds tend to last longer because roasting temperatures reduce mixing levels in walnuts.
Almonds can also pick up the smell of other foods in the fridge, so be sure to store them in an airtight container to prevent this from happening and to prevent excess moisture from entering. Cut almonds are usually packaged in cardboard boxes with a plastic liner or bulk fiber containers with a plastic liner. The plastic lining provides an important moisture barrier. Almonds contain a large amount of fat and become rancid if exposed to hot temperatures, extreme fluctuations in temperature and humidity.
Roasted almonds processed in California are generally packaged in vacuum-packed aluminum bags and shipped in 25-pound (11.3 kg) boxes. Almonds are a big part of your diet, but to get their full benefits, they must be stored properly. On the other hand, shelled almonds will stay fresh for years if stored in a well-ventilated place in the pantry. When bitter almonds undergo heat treatments such as baking, microwaving, roasting or boiling, the cyanide content of bitter almonds is reduced by up to 98%.
