Analysis of Chemical Contents in Raw Material of Rich Minerals Sea Salt

Abstract

The mineral content of seawater is a natural raw material to produce rich mineral sea salt. Rich mineral sea salt is a consumption salt with a NaCl content of <50% used to live a low sodium diet for a healthy lifestyle. In general, traditional sea salt was produced with the multistage evaporation method to obtain a NaCl content of ≥ 94.7%, whereas the production of rich mineral sea salt uses a total evaporation method and then removes the salt flower at a certain concentration to get low sodium chlorine and contain other natural minerals. This study aims to analyze the chemical content of the raw material of rich mineral sea salt. The location of seawater used as raw material for rich mineral sea salt is Camplong District, Sampang Regency. Samples were obtained from sea level with a distance of ± 400 m from the coastline and carried out during high tide conditions. The chemical analysis of seawater samples consists of Na, Mg, Ca, K, Fe, Cl− dan SO42−. The analysis method is based on the Indonesian National Standard of environmental quality test. The results of the major mineral analysis showed that the largest mineral content of seawater was calcium (Ca2+) at 492.350±10.395 mg/L and Sodium (Na+) at 482,000±1.979 mg/L. In contrast, the smallest mineral content is iron mineral (Fe2+) of < 0.08 mg/L. These results will be used for preliminary data before producing naturally rich mineral sea salt.

“…Non-compliance with mineral content requirements in salt has significant health implications, including nutritional deficiencies [ 70 ], increased health risks [ 20 ], population health burdens [ 28 ], and vulnerability to certain demographic groups [ 35 ]. Inadequate mineral intake leads to osteoporosis [ 32 ], cardiovascular diseases [ 34 ], and muscle cramps [ 16 ], and legal and regulatory consequences for manufacturers and producers, such as recalls and fines [ 9 ], undermine consumer confidence in food products' safety and quality [ 2 ], leading to skepticism about fortification programs [ 68 ]. According to Ref.…”

“…This suggests that non-iodate salts are most likely present in the public environment, undermining the effectiveness of iodization programs and exacerbating nutritional deficiencies among the population [ 9 , 12 ]. Other minerals such as Nitrate (NO 3 − ), phosphate (PO 4 3− ), sulphate (SO 4 2− ), iron (Fe 2+ or Fe 3+ ), manganese (Mn 2+ ), ammonium (NH 4 + ), and copper (Cu 2+ ) are necessary for general health and nutrition [ 8 , 16 , 32 , 33 ], their deficiencies have profound effects on increased risk of anemia, osteoporosis, and cardiovascular disease [ 34 ].…”
