Sodium alginate is a by-product after extracting iodine and mannitol from kelp or Sargassum of brown algae, and its molecule is composed of β -D- mannuronic acid (β -D-mannuronic, m) and α -L- guluronic acid (α -l -L-guluronic, g) press (1→ 4) key connection, which is a kind ofNatural polysaccharideIt has the stability, solubility, viscosity and safety required by pharmaceutical excipients. Sodium alginate has been widely used in food industry and medicine.

Sodium alginate is a non-toxic food, which was included in the United States Pharmacopoeia as early as 1938. Sodium alginate contains a lot of — COO--,which can show polyanionic behavior in aqueous solution and has certain adhesion, can be used as a drug carrier for treating mucosal tissue. Under acidic conditions, — COO--into — COOH,ionization degreeWhen decreasing, the hydrophilicity of sodium alginate decreases, the molecular chain shrinks and the pH value increases, — COOH group dissociates constantly, and the hydrophilicity of sodium alginate increases and the molecular chain stretches. Therefore, sodium alginate has obvious pH sensitivity. Sodium alginate can quickly form gel under extremely mild conditions, when Ca2+, Sr2+ and so on are present.cationWhen it exists, Na+ on G units reacts with divalent cations, and G units pile up to form cross-linked network structure, thus forming hydrogel.

Because of these excellent characteristics, sodium alginate has been widely used in food industry and medicine.

The typhoon is coming! Typhoon Miaobai on the 2nd this year may be the "first stage" to land in Guangdong this year! Although the typhoon is approaching, but! It's still very hot during the day today! There will be showers or thunderstorms in the afternoon, and the rain will become more obvious at night.
The typhoon is coming! Will it affect kelp harvesting?

As of 8: 20 this morning (12th), typhoon warnings have been hoisted at 43 stations in Guangdong, including Haifeng, Lufeng and Shanwei, while blue warnings were hoisted at 25 stations and white warnings were hoisted at 15 stations. At present, Shanwei has released information on suspension of classes.

According to the Central Meteorological Observatory, this year's No.2 typhoon "Miaobai" (tropical storm class, English name: MERBOK) was located at 5 o'clock this morning (12th) in the northeastern South China Sea, about 345 kilometers south of Shanwei, Guangdong Province. The maximum wind force near the center was 8 (20m/s), the lowest pressure in the center was 996 hectopascals, and the radius of the 7-level wind circle was 140-260 kilometers.

It is estimated that Miaobai will continue to move to the north-west direction at a speed of about 20 kilometers per hour, and its intensity will be strengthened. The maximum intensity is expected to be tropical storm level or strong tropical storm level (9-10, 23-25m/s), and it will land in the coastal area from Zhuhai to Shantou at night on the 12th, and the intensity will still be tropical storm level or strong tropical storm level (9-10, 23-25m/s)According to the latest forecast of Guangdong Meteorological Observatory, "Miaobai" will land in the coastal area of Huilai in Shenzhen from this evening to midnight.

Precipitation forecast: From 08: 00 on the 12th to 08: 00 on the 13th, there will be heavy rain in central and eastern Guangdong, including heavy rain (100-180mm) in the southeast of Guangdong.

Experts pointed out that there are three unfavorable factors in defending against typhoon Miaobai. First, Miaobai will become the first typhoon to land in Guangdong this year, and its later path and intensity are very uncertain, so the defense preparation time is tight. Second, after landing, "Miaobai" will go deep into inland areas and bring heavy rainfall to Meizhou, Heyuan and other places. This heavy rainfall basically coincides with the heavy rainfall area in central and eastern Guangdong in early June. In some areas, the disaster prevention ability is reduced in the early stage, and the soil water content in the area tends to be saturated, which is likely to lead to secondary disasters such as flash floods and mudslides. All localities must attach great importance to it and do all kinds of defense work as soon as possible. Third, after the change of party committees and governments at all levels, some new cadres lack experience in wind prevention, and the change of village residence is under way, which is prone to empty responsibilities and carelessness.

The Guangdong Provincial Defense General requires that the relevant regions and departments resolutely overcome the paralysis, proceed from the most unfavorable situation, further strengthen preventive measures, and do their best to prevent tropical cyclones in the South China Sea.

Shanghai dawn, the best news at this time is that the boss said "get off work early". Affected by the tropical depression, from today (12th) afternoon to the day after tomorrow (14th), there were heavy rains in eastern Guangdong, some cities and counties, and some cities and counties in the Pearl River Delta had moderate to heavy rains.
     Because the typhoon is located in the south, it will not affect the Shandong Peninsula, so it will not be affected by rainfall and strong winds, and the kelp harvest will not be affected.
