Delice salt is a natural spring salt obtained from the evaporation of spring water from the Central Anatolia region of Turkey and is a food grade salt with a geographical indication certificate. The aim of this study was to evaluate the compliance of Delice natural spring salt (Delice NSS), a commercial product, with food grade criteria by physicochemical characterizations and to investigate whether it contains microplastics. The NaCl%, moisture suspended solids and acid insoluble matter contents of Delice NSS were analyzed and determined as 98.79% (w/w), 0.301% (w/w), 0.16% (w/w) and 0.01% (w/w), respectively. Sodium, other minerals, and heavy metals were analyzed by inductively coupled plasma-optical emission (ICP-OES) spectrometry. In addition, fluoride, nitrate, and sulphate ions were analyzed by ion chromatography (IC). The chemical and thermal properties of Delice NSS were characterized by FTIR, X-ray fluorescence (XRF) and thermogravimetric analyzer (TGA). Moreover, Delice NSS was investigated whether it contains microplastics and some particles were detected under fluorescence microscopy. However, it was concluded that particles were not microplastics after TGA and FTIR analyses. The results revealed that Delice NSS does not carry a risk in terms of physicochemical properties as a foodstuff.

德利采盐是一种天然泉水盐，由土耳其安纳托利亚中部地区的泉水蒸发制得，是一种具有地理标志证书的食品级盐。本研究的目的是通过理化特性评估商业产品德利采天然泉水盐（Delice NSS）是否符合食品级标准，并调查其是否含有微塑料。对Delice NSS的NaCl%、水分、悬浮固体和酸不溶物含量进行了分析，分别测定为98.79%（w/w）、0.301%（w/w）、0.16%（w/w）和0.01%（w/w）。通过电感耦合等离子体发射光谱法（ICP-OES）分析钠、其他矿物质和重金属。此外，通过离子色谱法（IC）分析氟化物、硝酸盐和硫酸盐离子。采用傅里叶变换红外光谱（FTIR）、X射线荧光光谱（XRF）和热重分析仪（TGA）对Delice NSS的化学和热性能进行了表征。此外，对Delice NSS是否含有微塑料进行了研究，在荧光显微镜下检测到了一些颗粒。然而，经TGA和FTIR分析后得出结论，这些颗粒不是微塑料。结果表明，Delice NSS作为食品在理化性质方面不存在风险。
