Why is sugar cane sweet? Is sugar cane sweet on top or underneath?

Fruits have a sweet taste! It's just that the depth of sweetness is different!

The lower part is sweet. The photosynthesis and respiration of sugarcane leaves are very strong, so the water and minerals absorbed by the roots are constantly transported to the tail and leaves of the stem, and the water content of sugarcane is particularly high.

Excess organic matter is constantly being transported downwards, so the lower organic matter of the sugarcane accumulates more and more. So the lower part of the cane is sweeter than the upper part. It is said that "there are no two sweet canes", which means that usually the cane is sweet at only one end, and the closer to the bottom the sweeter it is.

Sugarcane buying tips.

1. When choosing purple sugarcane, the skin is bright, with hoarfrost, the darker the color, the darker the color, and the older the sugarcane, the sweeter it is.

2. There may be insect mouths when sugarcane bends around, so we must choose relatively straight sugarcane, not too curved.

3. Choose sugarcane with few joints and uniformity, such sugarcane tastes more refreshing, so when we choose sugarcane, we must pay attention to the above points in order to buy good fresh sugarcane.

1. Look at the thickness.

First of all, when buying sugarcane, don't just be stupid and pick coarse, not that the thicker the cane, the sweeter, nor the finer the better, but choose the kind of sugarcane with moderate thickness. Because sugarcane that is generally too thick is likely to be eaten by hollow insects, it is not so sweet. If it is too fine, there is very little flesh in it and less juice, so the next time you pick sugarcane, it is best to choose sugarcane of equal thickness!

When buying sugarcane, don't be stupid and only pick the rough one, remember 4 points, sugarcane is sweet and juicy, and it is really useful.

2. Look at the epidermis.

When buying sugarcane, you can also take a look at the outer skin of sugarcane, high-quality fresh sugarcane, its skin color is dark purple, and glossy, if the outer skin color of sugarcane is relatively light, sugarcane may not be ripe, and it tastes more astringent. And there is a layer of hoarfrost on the surface that is clearly visible like grapes. Some people think that it is dust, but in fact it is not, this layer of hoarfrost is naturally hung during the growth of sugarcane, and it is the fruit powder secreted by sugarcane itself.

If there is no hoarfrost or less hoarfrost on the surface of the sugarcane, it means that the sugarcane has been stored for too long and it is not recommended to buy it.

3. Look at the section head.

We know that the appearance of sugarcane looks like a section, and this section is relatively hard, if you want to buy delicious sugarcane, you have to look at the section of sugarcane. Generally, the sugarcane with fewer knots and the distance between the knots will be sweeter, and the nutrients can be absorbed better with fewer knots, the sweetness is higher, and the bite is easier. If it is a sugarcane with a short knot head or a different distribution of knots, it is relatively hard and difficult to bite, and the taste is generally not sweet.

When buying sugarcane, don't be stupid and only pick the rough one, remember 4 points, sugarcane is sweet and juicy, and it is really useful.

4. Look at the bend straight.

Finally, when buying sugarcane, try to choose a straighter, straight-shaped sugarcane, which grows better in the growth process, while picking crooked, strange-shaped sugarcane is likely to have insect mouths, and the nutrient absorption is not good in the process of growth, and the taste will not be too sweet. Therefore, when you buy sugarcane, you should choose a relatively straight sugarcane.

When buying sugarcane, don't be stupid and only pick the rough one, remember 4 points, sugarcane is sweet and juicy, and it is really useful.

The above is the skills of selecting sugarcane, according to these methods to select, to ensure that the sugarcane picked is accurate and sweet, in addition, but also to pay attention to the integrity of the sugarcane skin, whether there is damage and cracks. If you find that the sugarcane has insect eyes and cracks, it is recommended that you do not buy it. If you find that the flesh is red, it means that the sugarcane has become moldy and spoiled, and eating it is not good for your health, so you can't eat it and can't buy it.

1.Selection of high-quality sugarcane: the principle of "touching, seeing, and smelling" should be mastered when identifying sugarcane, and touching is to test the softness and hardness of sugarcane; Look is to see whether the flesh of sugarcane is fresh (the texture of fresh sugarcane is hard, the part is milky white, and has a clear fragrance); Smell is to identify whether sugarcane has an odor or not.

The mildew cane has a soft texture, and the color of the pulp is slightly darker, light brown, and it smells tasteless or slightly wine trough;

2.Do not eat those sugarcane that have been spoiled by fungal infection, otherwise, it will cause vomiting, convulsions, coma and other poisoning symptoms after eating;

3.50 grams of cane juice and wine are commonly used in folks, mixed and taken once in the morning and once in the evening, which has a good effect on chronic gastritis and nausea and vomiting.

In short, the color is bright, the color is lighter, and the thickness is the sweetest.

The plants will provide some nutrients for their own growth, while the rest will be stored. Most plants are stored in the roots. Of course, the same goes for sugar cane, which converts excess nutrients into sugars and accumulates in the roots.

Since most of the nutrients produced by sugarcane stems are sugars, the accumulated sugars are even thicker.

If you want to eat sweet sugar cane, you have to watch the sugar cane festival first. The cane knot should not be too tight or too loose. Sugar cane that is too tight tastes delicious.

Sugar cane that is too loose and too thin is not sweet. In conclusion, the cross-section of sugarcane should be well-proportioned, so sugarcane tastes sweet and cool.

In fact, the underside of the sugar cane is sweeter. The top is more bitter, so many people will choose to buy the bottom of the sugarcane when they buy it.

Of course, the lower section of sugarcane is sweeter, because sugarcane is generally thicker in the lower section, and it absorbs more nutrients, so it is naturally sweeter in the lower section.

Sugar cane contains sugar. Sugarcane is a solid herb of sugarcane, which grows rapidly through photosynthesis, and the plant's respiration will consume nutrients, but the respiration of sugarcane is small, and the nutrients are converted into sugar and stored in the sugarcane. Sugarcane is widely cultivated in Fujian and other areas in the southern Rechaifeng belt, which is suitable for planting Suizhen in places with fertile soil, abundant sunshine and large temperature difference between winter and summer.

Sugarcane is widely cultivated in southern tropical areas such as Fujian, China, and is suitable for planting in places with fertile soil, abundant sunlight, and large temperature differences between winter and summer.

It is a raw material for the manufacture of sucrose and can be refined into ethanol as an energy alternative.

Problem description: Leaf photosynthesis of sugarcane.

Sunlight and what produces sugar? 〉

Analysis: Because sugarcane is constantly consuming nutrients during the growth process. Small sugar cane is not sweet up and down.

When they grow up, on the one hand, the amount of sugar produced increases, and on the other hand, the consumption of nutrients decreases, and the excess sugar is stored in the lower part of the sugarcane. So ripe cane is sweeter than the upper part of the lower section. In addition, because sugarcane leaves need a lot of water for photosynthesis, most of the water in sugarcane itself is near the leaves of Nian Hui, and the roots are relatively small, so the concentration of sugar in the roots is relatively high, so the lower part of the sugarcane is sweeter than the upper section.
