เรื่องของเกลือกับอุตสาหกรรมอาหาร

[บ๊วยเค็ม]

ในอุตสาหกรรมอาหารส่วนใหญ่ผู้ผลิตจะใช้เกลือสมุทรมากกว่าเกลือสินเธาว์เพราะอะไรคะ

เรียน คุณบ๊วยเค็ม
ขอบคุณค่ะสำหรับคำถาม เหตุผล ก็น่าจะมาจาก
1  เหตุผลด้านโภชนาการ เพราะ ปริมาณไอโอดีนที่มีอยู่ในเกลือสมุทร (sea salt) มีมากกว่า ในเกลือสินเธาว์
2  เรื่องของรสชาติ เนื้อสัมผัส เกลือสมุทร ยังก็มีแร่ธาตุอื่น นอกจาก NaCl ที่ช่วยให้อาหารมีรสชาติดี ให้เนื้อสัมผัสที่ดี

ดู เหตุผลสนับสนุน ที่ post ตามมา นะคะ

Taste of sea salt
 
.....A commercial pack of sea salt Gourmets often believe sea salt to be better than ordinary table salt in taste and texture,[7] though one cannot always taste the difference when dissolved. In applications where sea salt's coarser texture is retained, it can provide different mouth feel and changes in flavor due to its different rate of dissolution. The mineral content also affects the taste. It may be difficult to distinguish sea salt from other untreated salts, such as pink Himalayan salt, or grey colored rock salt. Sea salt is purified less than the high mineral pink salt.....

Is sea salt better for your health than table salt?
Answer

Sea salt and table salt have the same basic nutritional value — both mostly consist of two minerals — sodium and chloride. However, sea salt is often marketed as a more natural and healthy alternative. The real differences between sea salt and table salt are in their taste, texture and processing, not their chemical makeup.
Sea salt is produced through evaporation of seawater, usually with little processing, which leaves behind some trace minerals and elements depending on its water source. These insignificant amounts of minerals add flavor and color to sea salt, which also comes in a variety of coarseness levels.

Sea salt is a broad term that generally refers to unrefined salt derived directly from a living ocean or sea. It is harvested through channeling ocean water into large clay trays and allowing the sun and wind to evaporate it naturally. Manufacturers of sea salt typically do not refine sea salt as much as other kinds of processed salt, so it still contains natural traces of other minerals, including iron, magnesium, calcium, potassium, manganese, zinc and iodine.
Proponents of sea salt rave about its bright, pure, clean flavor, and about the subtleties lent to it by these other trace minerals. Some of the most common sources for sea salt include the Mediterranean Sea, the North Sea, and the Atlantic Ocean (particularly in France, on the coast of Brittany). Sea salt is thought to be healthier and more flavorful than traditional table salt. Available in coarse, fine & extra fine grain size, and many sizes in between!
