The almond is a deciduous tree, growing 4–10 m (13–33 ft) in height, with a trunk of up to 30 cm (12 in) in diameter. The young twigs are green at first, becoming purplish where exposed to sunlight, then grey in their second year. The leaves are 8–13 cm (3–5 in) long, with a serrated margin and a 2.5 cm (1 in) petiole.

How do you identify an almond tree?
Identify almond trees by their rounded shape, reaching 15 to 20 feet tall and 10 to 15 feet wide. Almond trees have pale pink spring flowers and dark-green, alternate, 3- to 6-inch-long leaves with fine-toothed margins. Almonds produce fuzzy drupes that look like immature peaches; the hard, thick-shelled nuts are inside.
How do you know if almonds are bad?
"You'll get a handful of these almonds in your mouth, you'll take a couple of chews on them, and you're spitting them out they're so bad," said Alyson Mitchell, a food chemist at the University of California, Davis. While roasting does cause the bad almonds to darken, making them detectable, the two types look the same from the outside when raw.
How do you identify a nut tree?
How to Identify Nut Trees. Many types of nut trees exist, but the most common types include almond, butternut, chestnut, hickory, pecan and walnut. Identify types of nut trees by the characteristics of their leaves, flowers and nuts, as well as their size and form.
How do you harvest almonds?
Learning how to harvest almonds includes knowing when they are ripe, getting them off the tree, and drying them appropriately. Harvest almonds when the hulls begin to split open. Hull split will begin with the nuts at the top of the tree rather than the ones at eye level, so make sure to check the fruits that are higher up!

How To Store Almonds?
In order to store raw almonds for as long as possible, it is best to keep them cold. Therefore, you should place them in the fridge or freezer. The same goes for other almond products like almond butter, almond milk, and almond flour.
How Long Do Almonds Last?
Raw almonds can be stored for at least a year without concern. If you take care to keep them cool and dry, this period may be extended to up to two years.
How To Tell If Almonds Are Bad?
Do Almonds Go Bad? Of course, they do! Just like products made from almonds such as almond flour and almond milk, almonds do go bad eventually. However, it can sometimes be challenging to determine if your almonds have gone bad or not. Here are some of the key signs that your almonds should go in the trash.
What To Do With Almonds About To Go Bad?
If you’ve got a massive packet of almonds you need to find a use for soon, you can consider making almond flour or almond butter out of them. This is relatively easy with the right tools.

Now You Know!
If you are trying to boost your health, grabbing a handful of almonds is an excellent idea. Almonds have been shown to lower cholesterol while providing a good source of iron and protein. They are ideal for vegetarians, vegans, diabetics, and anyone who is watching their weight.
The Danger of Bitter Almonds
Bitter almonds are a variety of regular, sweet almonds. Bitter almonds contain traces of prussic acid—also known as hydrocyanic acid—in its raw state. Hydrocyanic acid is a solution of hydrogen cyanide and water. The byproduct is an organic version of the well-known poison, cyanide.
The Differences Between Bitter and Sweet Almonds
All almonds fall into one of two categories. Almonds are either sweet or bitter. Sweet almonds are scientifically called Prunus dulcis, dulcis being Latin for "sweet." You can scoop out a handful of sweet almonds and eat them on the spot. They might be crumbled and sprinkled atop desserts and other dishes.

Almond Pasteurization and Raw Almonds
The most common form of pasteurization consists of using steam to kill any surface bacteria that might be on the almonds. Our concern was what that did to the nutritional value of the nuts themselves.
Effect of different processing methods on nut nutrition?
When we looked at the testing results, it became clear that there was no significantly measurable difference between the unpasteurized almonds and the pasteurized almonds. The levels of damaged fats were about the same and within the margin of error for the test.
How do we apply what we've learned at Legendary Foods?
As a result of this test, we use pasteurized nuts that have not had any additional heating wherever possible. This ensures product safety while offering the best possible fat in the nuts snacks themselves.
Overview
The almond (Prunus amygdalus, syn. Prunus dulcis) is a species of tree native to Iran and surrounding countries, including the Levant. The almond is also the name of the edible and widely cultivated seed of this tree. Within the genus Prunus, it is classified with the peach in the subgenus Amygdalus, distinguished from the other subgenera by corrugations on the shell (endocarp) surroundin…
Description
The almond is a deciduous tree growing to 4–12.2 metres (13–40 feet) in height, with a trunk of up to 30 centimetres (12 inches) in diameter. The young twigs are green at first, becoming purplish where exposed to sunlight, then gray in their second year. The leaves are 8–13 cm (3–5 in) long, with a serrated margin and a 2.5 cm (1 in) petiole.
Taxonomy
The seeds of Prunus dulcis var. dulcis are predominantly sweet but some individual trees produce seeds that are somewhat more bitter. The genetic basis for bitterness involves a single gene, the bitter flavor furthermore being recessive, both aspects making this trait easier to domesticate. The fruits from Prunus dulcis var. amara are always bitter, as are the kernels from other species of ge…
Distribution and habitat
Almond is native to Iran and surrounding countries and ancient remains of almonds were discovered in the Levant area. It was spread by humans in ancient times along the shores of the Mediterranean into northern Africa and southern Europe, and more recently transported to other parts of the world, notably California, United States. The wild form of domesticated almond grows in parts of the Levant.
Cultivation
Almonds were one of the earliest domesticated fruit trees, due to "the ability of the grower to raise attractive almonds from seed. Thus, in spite of the fact that this plant does not lend itself to propagation from suckers or from cuttings, it could have been domesticated even before the introduction of grafting". Domesticated almonds appear in the Early Bronze Age (3000–2000 BC), such a…
Toxicity
Bitter almonds contain 42 times higher amounts of cyanide than the trace levels found in sweet almonds. Extract of bitter almond was once used medicinally but even in small doses, effects are severe or lethal, especially in children; the cyanide must be removed before consumption. The acute oral lethal dose of cyanide for adult humans is reported to be 0.5–3.5 mg/kg (0.2–1.6 mg/lb) of body weight (approximately 50 bitter almonds), so that for children consuming 5–10 bi…
Uses
Almonds are 4% water, 22% carbohydrates, 21% protein, and 50% fat (table). In a 100-gram (3+1⁄2-ounce) reference amount, almonds supply 2,420 kilojoules (579 kilocalories) of food energy. The almond is a nutritionally dense food (table), providing a rich source (20% or more of the Daily Value, DV) of the B vitamins riboflavin and niacin, vitamin E, and the essential minerals calcium, cop…
In culture
The almond is highly revered in some cultures. The tree originated in the Middle East. In the Bible the almond is mentioned ten times, beginning with Genesis 43:11, where it is described as "among the best of fruits". In Numbers 17 Levi is chosen from the other tribes of Israel by Aaron's rod, which brought forth almond flowers. The almond blossom supplied a model for the menorah which stood in the Holy Temple, "Three cups, shaped like almond blossoms, were on one branch, with a knob …
