sprouts]] Sprouting is the natural process by which or germination and put out shoots, and already established plants produce new leaves or , or other structures experience further growth.
In the field of nutrition, the term signifies the practice of germinating seeds (for example, or ) to be eaten Raw food or Cooking, which is considered more nutritious.
Bean sprouts are a common ingredient across the world. They are particularly common in Eastern Asian cuisine. It typically takes one week for them to become fully grown. The sprouted beans are more nutritious than the original beans, and they require much less cooking time. There are two common types of bean sprouts:
Common sprouts used as food include:
Although whole oats can be sprouted, oat groats sold in food stores, which are Husk and have been steamed or roasted to prevent Rancidification, will not sprout. Whole oats may have an indigestible hull which makes them difficult or even unfit for human consumption. In the case of rice, the Rice hulls of the paddy is removed before sprouting. Brown rice is widely used for germination in Japan and other countries, becoming germinated brown rice. Quinoa in its natural state is very easy to sprout, but when polished, or pre-cleaned of its saponin coating (becoming whiter), it loses its power to germinate.
Sprouts of the family Solanaceae (tomato, potato, paprika, and aubergine/eggplant) and the family Polygonaceae (rhubarb) cannot be eaten raw, as they can be poisonous. Some sprouts can be cooked to remove the relevant toxin, while others cannot.This is an example.
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 toxic chemical dressings. Several countries, such as New Zealand, require that some varieties of imported edible seed be heat-treated, thus making it impossible for them to sprout.
Typically the seeds are first rinsed to remove soil, dirt and the mucilaginous substances produced by some seeds when they come in contact with water. Then they are soaked for from 20 minutes to 12 hours, depending on the type and size of the seed. The soaking increases the water content in the seeds and brings them out of Seed dormancy. After draining and then rinsing seeds at regular intervals, the seeds then germinate, or sprout.
For home sprouting, the seeds are soaked (big seeds) or moistened (small), then left at room temperature () in a sprouting vessel. Many different types of vessels can be used as a sprouting vessel. One type is a simple glass jar with a piece of cloth or nylon window screen 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 swell, may stick to the sides of the jar, and begin germinating within a day or two.
Another sprouting technique is to use a pulse drip method. The photo below on the right shows crimson clover sprouts grown on urethane foam mats. It is a one-way watering system with micro-sprinklers providing intermittent pulses of fresh water to reduce the risk of bacterial cross-contamination with Salmonella and E. coli during the sprouting process.
Sprouts are rinsed two to four times a day, depending on the climate and the type of seed, to provide them with moisture and prevent them from souring. Each seed has its own ideal sprouting time. After three to five days the sprouts will have grown in length and will be suitable for consumption. If left longer they will begin to develop leaves, and are then known as baby greens. A popular baby green is a sunflower after 7–10 days. Refrigeration can be used as needed to slow or halt the growth process of any sprout.
Common causes for sprouts becoming inedible:
can be sprouted either in light or dark conditions. Those sprouted in the dark will be crisper in texture and whiter, as in the case of commercially available Chinese Bean Sprouts, but these have less nutritional content than those grown in partial sunlight. Growing in full sunlight is not recommended, because it can cause the beans to overheat or dry out. Subjecting the sprouts to pressure, for example, by placing a weight on top of them in their sprouting container, will result in larger, crunchier sprouts similar to those sold in grocery stores.
A very effective way to sprout beans like or azuki is in colanders. Soak the beans in water for about 8 hours then place in the colander. Wash twice a day. The sprouted beans can be eaten raw or cooked.
Sprouting is also applied on a large scale to barley as a part of the malting process. Malted barley barley is an important ingredient in beer and is used in large quantities. Most malted barley is widely distributed among retail sellers in North America.
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 small when eaten, they are usually called "soaks".
Raw contain which can be reduced by sprouting or cooking. A downside to consuming raw sprouts is that the process of germinating seeds can also be conducive to harmful bacterial growth.
Sprouts are rich in digestible energy, vitamins, minerals, , proteins, and , as these are necessary for a germinating plant to grow.
"An increase in proteolytic activity during sprouting is desirable for nutritional improvement of cereals because it leads to hydrolysis of prolamins and the liberated amino acids such as glutamic and proline are converted to limiting amino acids such as lysine."
To minimize the impact of the incidents and maintain public health, both the U.S. Food and Drug Administration (FDA) and Health Canada issued industry guidance on the safe manufacturing of edible sprouts and public education on their safe consumption. There are also publications for hobby farmers on safely growing and consuming sprouts at home. The recommendations include development and implementation of good agricultural practices and good manufacturing practices in the production and handling of seeds and sprouts, seed disinfection treatments, and microbial testing before the product enters the food supply.
In June 2011, contaminated fenugreek sprouts (grown from seed from Egypt) in Germany was identified as the source of the which German officials had at first wrongly blamed on cucumbers from Spain and then on mung bean sprouts. In addition to Germany, where 3,785 cases and 45 deaths had been reported by the end of the outbreak, Shiga toxin-producing E. coli (STEC): Update on outbreak in the EU, 27 July 2011 a handful of cases were reported in several countries including Switzerland, Poland, the Netherlands, Sweden, Denmark, the United Kingdom, Canada, and the USA. Virtually all affected people had been in Germany shortly before becoming ill.
Phytic acid, an anti-nutritional factor, occurs primarily in the seed coats and germ tissue of plant seeds. It forms insoluble or nearly insoluble compounds with many metal ions, including those of calcium, iron, magnesium, and zinc, reducing their dietary availability. Diets high in phytic acid and poor in these minerals produce mineral deficiency in experimental animals (Gontzea and Sutzescu, 1968, (1968). 9783805508568, S. Karger; 1 edition (August 28, 1968). ISBN 9783805508568 as cited in Chavan and Kadam, 1989). The latter authors state that the sprouting of cereals has been reported to decrease levels of phytic acid. Similarly, Shipard (2005) (2025). 9780975825204, David Stewart. ISBN 9780975825204 states that enzymes of germination and sprouting can help decrease the detrimental substances such as phytic acid. However, the amount of phytic acid reduction from soaking is only marginal, and not enough to fully counteract its anti-nutrient effects.
