Is sugarcane an allergy-inducing food?

Irritating foods are foods that have the effect of aggravating human conditions. Especially when people have allergies or skin diseases, they should not eat irritating foods because they will aggravate the severity of these conditions. Common foods that cause allergies in our daily lives include seafood, but sugarcane is a plant that is available in large quantities in winter. Many people prefer to eat sugar cane because it tastes sweet, but is sugar cane considered an allergenic food?

Is sugarcane a hair-raising food?

Sugarcane is actually not a food that causes allergies.

Fascinating foods refer to foods that are rich in nutrition or have irritating properties and are particularly likely to induce certain diseases (especially old illnesses) or aggravate existing diseases.

Most foods in our lives are not allergenic. The most basic vegetables, staple foods, and fruits are mostly not allergenic. For example, tomatoes, cucumbers, cabbage, rapeseed, pakchoi, winter melon, bitter melon, mung beans, coix seed, red dates, bananas, apples, oranges, watermelons, strawberries, potatoes, kidney beans, white radish, carrots, etc. can all be eaten.

Sugarcane knowledge

Sugarcane is an annual or perennial tropical and subtropical herb and a C4 crop. The sweet cylindrical stem is erect, tillering, clustered, and has nodes with buds on the nodes; the internodes are solid, covered with wax powder, purple, red or yellow-green in color; the leaves are clustered, with thick white midribs; large panicles are terminal, with long silver hairs at the base of the spikelets, and small oblong or oval caryopsis.

Sugarcane is a tall, solid perennial herb. The rhizome is thick and well developed. The culm is 3-5(-6) meters tall. 2-4(-5)cm in diameter, with 20-40 nodes, the lower internodes are shorter and thicker, covered with white powder. The leaf sheath is longer than its internodes, and is glabrous except for the soft hairs at the sheath mouth; the ligule is very short and ciliated, the leaf blade is up to 1 meter long, 4-6 cm wide, glabrous, with a thick, white midrib and serrated and rough edges. The panicle is large, about 50 cm long. The main axis is glabrous except for the nodes, and the part below the inflorescence is not pubescent with filamentous pubescence. The racemes are mostly whorled and dense; the internodes of the raceme axis and the spikelet stalk are glabrous; the spikelets are linear-oblong, 3.5-4 mm long; the base has filamentous pubescence 2-3 times longer than the spikelets; the first glume is veinless, not pubescent, with a pointed apex and a membranous margin; the second glume has 3 veins, the midrib is ridged, rough, glabrous or ciliated; the first lemma is membranous, nearly as long as the glume, and glabrous; the second lemma is small, awnless or degenerate; the second palea is lanceolate; the scales are glabrous. Chromosome 2n=60, 80, 90 (Bremer, 1931), 68 (Kuwada Y., 1915), 80 (Price, 1958).

What to do if sugarcane is not sweet

In fact, there is generally no remedy. You can only pay attention next time you buy sugarcane. Be careful to choose some good sugarcane so that it will taste good.

1. As the sugar grows, the amount of sugar produced increases, while the amount of nutrients consumed decreases. The excess sugar is stored in the lower part of the sugarcane. Therefore, the lower part of mature sugarcane is sweeter than the upper part. In addition, since sugarcane leaves need a lot of water for photosynthesis, sugarcane mainly relies on roots to absorb water and nutrients during the seedling stage, and then delivers them to the leaves. The leaves absorb carbon dioxide and the nutrients delivered to them, and produce the nutrients they need under the sun.

2. As the sugarcane grows bigger, you need to peel its leaves several times. This can accelerate the upward growth of the sugarcane and allow the stalk to be directly exposed to sunlight, because the stalk is the main part of sugar production.

3. Check whether the sugarcane is straight. Bent sugarcane may have fallen over or have worm holes. Straight sugarcane is sweeter.

4. The reason why sugarcane becomes sweet after being exposed to the sun is that it loses water, which causes the proportion of sugar to increase; the reason why sweet potatoes become sweet after being stored for a long time is because starch is decomposed into sugars. Sweet potatoes are rich in starch, but starch itself is not sweet, and the decomposition products are sugars such as glucose, so they become sweet.

5. All sugars are first stored in the roots, so the sugarcane grows from the bottom to the top, but the sugar stored is always more concentrated as it goes down. Therefore, the root of sugarcane is much sweeter than the head of sugarcane.
