Many buyers frequently confuse mineral salts, table salt and food additives, holding misunderstandings regarding their applications, applicable sectors, pricing and raw material sources. Based on frequent inquiries from frontline business scenarios, this article systematically sorts out core industry knowledge, corrects prevalent misconceptions, and highlights the core strengths of Penglai Marine’s products. Worth saving for professional reference!
Q1: What are mineral salts? How do they differ from food additives?
The two differ fundamentally in product hierarchy and inherent properties and must never be equated.
Mineral salts are high-purity basic bulk raw materials rich in essential trace elements for the human body. Featuring stable indicators, universal compatibility and extensive application scenarios, they serve as fundamental materials supporting R&D and manufacturing across numerous industries, including food, pharmaceuticals, cosmetics, general industry and animal feed.
Food additives, by contrast, are legally compliant ingredients specially formulated for finished food products, with nutritional fortifiers classified as a subcategory thereof. Strictly speaking, only food-grade and pharmaceutical-grade mineral salts can be used as raw materials to manufacture food additives and nutritional fortifiers. Industrial-grade and feed-grade mineral salts fail to meet impurity and heavy metal thresholds, and are strictly prohibited from food processing applications.
Q2: Are mineral salts exclusively used in the food industry?
Mineral salts are universal essential bulk materials far beyond the food sector.
Apart from conventional food, functional food and health food, they are also applied in pharmaceutical raw materials, cosmetic formulations, livestock & poultry feed, industrial manufacturing, tobacco and other fields. Graded product lines are precisely tailored to satisfy manufacturing, R&D and quality control benchmarks of each respective industry.
Q3: Can mineral salts be consumed directly?
Direct ingestion or self-formulated oral administration is strictly forbidden.
Mineral salts are highly concentrated mineral raw materials with intensely enriched trace elements, fundamentally different from common edible table salt for seasoning. Human trace element intake is subject to stringent safety thresholds. Direct consumption or arbitrary formulation may lead to excessive intake, burden the metabolic system and cause nutritional imbalance.
The proper application method requires professional formula matching and standardized industrial processing before end use. For daily mineral supplementation, consumers are advised to select qualified finished health products and functional foods with scientifically calibrated formulas for safe and efficient absorption.
Q4: What causes drastic price gaps among commercially available mineral salts?
Pricing discrepancies of mineral salts stem mainly from four determining factors: raw material sources, production techniques, product grades and quality control protocols.
Low-end products adopt inferior feedstock and crude production processes, accompanied by high impurity levels, unstable chemical composition and inconsistent batch performance. Mostly categorized as basic industrial or feed grades with minimal standardized QC management, they come with low production costs and competitive low selling prices.
Premium products are manufactured from high-purity feedstock via refined extraction and multi-stage purification processes, delivering uniform composition and consistent batch quality. High-spec grades including food grade and pharmaceutical grade undergo rigorous screening for impurities and heavy metals. Supported by complete qualification certification and closed-loop full-process quality management systems, these products boast markedly improved purity, safety and stability, delivering higher comprehensive application value.
Q5: Origin of the brand name Penglai Marine. Do all its products derive from seawater sources?
Numerous clients misjudge the brand name and assume all products are extracted from the ocean. In fact, "Penglai Marine" is a geographic brand title inspired by Penglai’s coastal geographic features, bearing no mandatory link to product raw material origins.
The company’s core mainstream products are produced from terrestrial high-purity mineral ores, alongside a series of specialty items fabricated via seawater-derived processes to upgrade overall product performance:
Magnesium series (magnesium oxide, magnesium hydroxide, magnesium carbonate): produced from marine brine
Calcium carbonate: supplied in two variants from terrestrial mineral ores and biologically extracted marine oyster shells to meet diverse production demands
High-end products such as magnesium glycinate: manufactured with seawater-based technological routes to rigorously control heavy metal residues, reduce impurity content and elevate product purity and application safety
Q6: Does Penglai Marine provide export services? What are its export capabilities and certification credentials?
Penglai Marine boasts mature global export capabilities with well-established overseas business layouts and widespread market recognition. The company currently serves over 600 cooperative clients worldwide, with products exported to more than 50 countries and regions. Exports account for over 70% of total sales, covering mainstream international markets including Europe, America, Japan, South Korea, Australia and Southeast Asia.
All products comply with domestic and international authoritative specifications, conforming to Chinese national standards, Chinese Pharmacopoeia (ChP), United States Pharmacopeia (USP) and British Pharmacopoeia (BP) requirements. The enterprise holds a full portfolio of import & export certifications: ISO9001, ISO22000, FSSC22000, ISO14001 and GMP system certifications, plus Kosher and Halal special certifications. These credentials fully satisfy market access and inspection standards for food, pharmaceutical and feed industries across global regions, guaranteeing stable supply and consistent product compliance.
