Sprouting is the practice of soaking, draining and then rinsing seeds at regular intervals until they germinate, or sprout. This can be a semi - automated or fully automated process when done on a large scale for commercial use.

Seeds that can be sprouted

One of the most common sprouts is that of the mung bean (Vigna radiata); another common sprout is the Kala Chana & alfalfa sprout and the barley sprout.

Other seeds that can be sprouted include adzuki bean, almond, amaranth, annatto seed, anise seed, arugula, basil, brown rice, navy bean, pinto bean, lima bean, broccoli, buckwheat, cabbage, canola seed, caragana, cauliflower, celery, chia seed, chickpeas, chives, cilantro (coriander, dhania), clover, cress, dill, fennel, fenugreek, flax seed, garlic, hemp seed, kale, kamut, kat, leek, green lentils, lupins, pearl millet, mizuna, mustard, oats, onion, black-eyed peas, green peas, pigeon peas, snow peas, peanut, psyllium, pumpkin, quinoa, radish, rye, sesame, soybean, spelt, sunflower, tatsoi, triticale, watercress, and wheat berries.

Sprouting is also applied on a large scale to barley as a part of the malting process. Malted barley is an important ingredient in beer and is used in huge quantities.

However, many sprouts are in fact toxic when eaten, like kidney beans. Some sprouts can be cooked to remove the toxin, while others will be toxic either way and should be avoided.1 So before eating any sprouts, find out if that species is edible as a sprout.

With all seeds, care should be taken that they are intended for sprouting or human consumption rather than sowing. Seeds intended for sowing may be treated with chemical dressings. Several countries, such as New Zealand, also require that some varieties of edible seed be heat-treated, thus making them impossible to sprout.

Many varieties of nuts, such as almonds and peanuts, can also be started in their growth cycle by soaking and sprouting, although because the sprouts are generally still very tiny when eaten, they are usually called "soaks."

Sprouting

To sprout seeds, the seeds are moistened, then left at room temperature (between 13 and 21 degrees Celsius) in a sprouting vessel. Many different types of vessels can be used. One type is a simple glass jar with a piece of cloth secured over its rim. ‘Tiered' clear plastic sprouters are commercially available, allowing a number of "crops" to be grown simultaneously. By staggering sowings, a constant supply of young sprouts can be ensured. Any vessel used for sprouting must allow water to drain from it, because sprouts that sit in water will rot quickly. The seeds will swell and begin germinating within a day or two.
