Removing fruits and vegetables, agricultural medicine, nutritionists teach you how to master the biggest principles by doing 3 steps

The Agricultural Committee announced the 109th Announcement of the Research Results of Agricultural Drug Retention Monitoring for Fruit and Farm Products. This time, 13,673 fruits and vegetables were tested in Taiwan. The unqualified rate of Taiwanese vegetable agricultural drug retention was as follows: peas 28.4%, celery 24.2%, stew 22.6%, leek 18%, beans 11.6%, cowpea 11.5%, okra 11.1%, chili pepper 10.4%, green stew 6.6%, green stew 6.32%, rapeseed 6.25%, spinach 6.2%, mustard 5.9%, bitter melon 5.5%, semi-small chard 5.32%, and green cabbage 5.26%.

Choose to buy vegetables and clean them correctly, and most agricultural medicines can be removed. {999 99}

This list has caused consumers to doubt. Luo Peilun, a nutritionist at Zhonghe Cong Hospital affiliated to Kaohsiung Medical University, emphasized that "encompassing" is the administrative control standard for the government to track whether agricultural medicine is properly sold and used, and is not the boundary of harm to human health. "If you fail to keep fruits and vegetables, it does not mean that you are toxic fruits and vegetables." It is recommended that consumers choose as much as possible to buy vegetables and clean them correctly before taking them to remove most agricultural medicines.

Nutritionist Ropelen said that if agricultural medicine is not used at all, it may increase the labor and price of agricultural products. Organic agriculture is of course a good way, but it is practically difficult to meet the needs of the public at a large scale, stable and affordable price.

Ropelen believes that rational, legal and safe use of agricultural medicine is a relatively economical and economical way under the goal of maintaining agricultural product production and quality. This is also the main reason why the government needs to set safety regulations and conduct continuous inspections to ensure that the amount of agricultural medicine remains in compliance with safety standards.

Remove the retention of agricultural medicine, "wash first and then cut" is the biggest principle.

Agricultural medicines are divided into two types, one is "systemic agricultural medicine" and the other is "contact agricultural medicine". Ropelen said that systematic agricultural medicines are applied to the soil during planting and are scattered in the plants. They decompose naturally in the plants at the same time and cannot be removed through cleaning. The farmers set a safe harvest period. Contact agricultural medicines are on the surface of fruits and vegetables. Cleaning with flowing water can reduce the problem of agricultural medicine.

"Wash first and then cut is the principle." Li Guiyu, a senior nutritionist, said that many people have made mistakes. The three basic steps of cleaning fruits and vegetables are to "soak" for more than 3 minutes before the fruits and vegetables are cut. This is the agricultural medicine that can dissolve the surface; if it is cut at this time, the agricultural medicine may be poured in. Next, it is to "wash" with flowing water to reduce the amount of agricultural medicine through washing. Finally, it is "cutting", and then cut before cooking.

Root pendants, colored peppers, etc. can be paired with soft brushes; the nutrients of cold vegetables are not bad.

Like potatoes, soak and wash, you should also use a soft brush to brush the grooved part; there are also pedicles like colorful peppers that can be brushed under flowing water. Leaf vegetables are like high-quality cabbage and heart-bread cabbage. You can first remove leaves that are not as good as the outside quality, and then wash them.

Some family hosts may feel sorry for the flow of washing vegetables and water, or what should they do when they encounter a water shortage? Nutritionist Li Bingyu suggested that cold vegetables can be selected during water shortage, because the cold vegetables are prepared by cleaning, killing cyanine, and quickly refrigerating, and the nutrients are completely preserved, and there will be no problem of nutrient loss, but some tastes are not as good as fresh vegetables. There are many varieties of cold vegetables, not only the three-color beans in my impression, but also spinach, okra, cauliflower, croaker, green beans, etc.

It is not as efficient as using Xiaosu to wash vegetables; salt water can eliminate fat-soluble substances.

As for the correct idea of washing vegetables with sausage and salted bait? Ropelen said that the chemical name of Suda Xiao is hydrazine carbonate, which is weakly supple and is often used to neutralize acidity in foods. There are many acidic agriculture drugs that degrade faster in a singular environment, but it may take several hours. Generally, washing vegetables can only take more than ten minutes, so the effect of using Xiaosu to clean fruits and vegetables in a short time is not necessarily better than washing with clean water. For example, the malathion malathion, commonly used in cruciferous vegetables or leaf vegetables, has a semi-degradation cycle of 6 days in the pH7 environment and a semi-degradation cycle of 9, and a half-degradation cycle of 9.

How effective is it to wash vegetables with salt? Ropelen said that the ingredients of the agricultural medicine attached to fruits and vegetables are mostly fat-soluble substances. If washed with salt water, the solubility of the salt water to fat-soluble compounds is not good. The diluted salt water is mostly treated with soaking and non-flowing water, and the effect is no longer as clean as washing with clean water.

Vegetable preservation skipping

Senior medical nutritionist Li Guiyu said that the key to extending the shelf life of fruits and vegetables is to "remove the water" before storage. Here are a few small skippings:

1. Do not cut or wash the fruits and vegetables, wrap them with a kitchen towel, put them in the dry prototype, and wipe or dry the fruits and vegetables before putting in. Only one kind of fruits and vegetables can be placed in a bag. If the paper towel is worn, it must be replaced to avoid water affecting the fruits and vegetables.

2. The leaves or leaves should be removed from the external layer with poor quality or leaves.

3. The squid should be removed, cleaned and dried, and sealed with the fresh film.

4. If there are fruit stems like bell peppers, you need to keep them dry.

5. Classify according to different types of vegetables. After drying the moisture, wrap it in cowhide paper or white soft wrapping paper.

6. Temperature is an important factor affecting the failure of agricultural products. It is preserved at refrigeration temperature to reduce the physiological activity of fruits and vegetables.
