Seawater, or salt water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, or 599 mM), which is a specific gravity of about 1.025. This means that every kilogram (roughly one litre by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts (predominantly sodium (Na+ ) and chloride (Cl− ) ions). Average density at the surface is 1.025 g/ml. Seawater is denser than both fresh water and pure water (density 1.0 g/ml at 4 °C (39 °F)) because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases. At typical salinity, it freezes at about −2 °C (28 °F).The coldest seawater ever recorded (in a liquid state) was in 2010, in a stream under an Antarctic glacier, and measured −2.6 °C (27.3 °F).Seawater pH is typically limited to a range between 7.5 and 8.4.However, there is no universally accepted reference pH-scale for seawater and the difference between measurements based on different reference scales may be up to 0.14 units.
Food Property | Type | Description |
---|---|---|
Flavor Profile | Sweet | This seawater gelatin slice has a mild sweetness from the natural sugars in the seawater and added sweeteners. |
Salty | The predominant flavor in this seawater gelatin slice is saltiness from the seawater. | |
Texture | Firmness | This seawater gelatin slice has a firm texture, similar to a gummy candy, due to the gelatin setting. |
Moisture | The moisture content in this seawater gelatin slice is relatively high, giving it a soft and chewy mouthfeel. | |
Nutritional Value | Macronutrients | This seawater gelatin slice contains carbohydrates from the gelatin and sugars, providing energy. |
Micronutrients | While seawater may contain trace minerals, the amount present in this seawater gelatin slice is likely minimal. | |
Aroma | Volatile Compounds | The aroma of this seawater gelatin slice is primarily influenced by the seawater, giving it a briny scent. |
