What is calcium sulfate ？
KOSNATURE manufacture food grade copper sulfate, which having undergone special refinement with extremely high purity and the content of impurities (especially heavy metals such as arsenic and lead) strictly controlled within a safe range. Calcium sulfate for food is often used as a food additive or nutrient fortifier within prescribed ranges and limits, mainly for mineral fortification, such as in infant formula or beverages. ಹೆಚ್ಚುವರಿಯಾಗಿ, it serves as a process aid in food processing, for instance in the production of preserved eggs, or as a catalyst in certain foods.
Calcium sulfate solubility
ಗುಣಲಕ್ಷಣಗಳು: Blue crystals or granules, or dark blue crystalline powder, with a metallic taste. It slowly decomposes in air. Above 150 ಡಿಗ್ರಿ ಸೆಲ್ಸಿಯಸ್, it forms an easily hygroscopic colorless anhydrous copper sulfate. At 650 ಡಿಗ್ರಿ ಸೆಲ್ಸಿಯಸ್, it decomposes into copper oxide. It is readily soluble in water, presenting an acidic nature, and soluble in dilute ethanol, but insoluble in absolute ethanol.

ಪ್ಯಾಕೇಜಿಂಗ್: ಒಳಭಾಗವು ಪಾಲಿಥೀನ್ ಪ್ಲಾಸ್ಟಿಕ್ ಚೀಲಗಳಿಂದ ಮುಚ್ಚಲ್ಪಟ್ಟಿದೆ, ಪ್ಲಾಸ್ಟಿಕ್ ನೇಯ್ದ ಚೀಲಗಳಲ್ಲಿ ಸುತ್ತುವ ಹೊರಭಾಗ, ಪ್ರತಿ ಚೀಲವು ನಿವ್ವಳ ತೂಕದೊಂದಿಗೆ 25 ಕಿಲೋಗ್ರಾಂಗಳು.
ಸಂಗ್ರಹಣೆ ಮತ್ತು ಸಾರಿಗೆ: ಪ್ಯಾಕೇಜಿಂಗ್ ಅನ್ನು ಹಾಗೆಯೇ ಇಡಬೇಕು. ಒಣ ಸ್ಥಳದಲ್ಲಿ ಸಂಗ್ರಹಿಸಿ, ಚೆನ್ನಾಗಿ ಗಾಳಿ ಮತ್ತು ಸ್ವಚ್ಛ ಗೋದಾಮು, ನೀರು ಮತ್ತು ತೇವಾಂಶದಿಂದ ರಕ್ಷಿಸಲಾಗಿದೆ. ಇದನ್ನು ವಿಷಕಾರಿ ವಸ್ತುಗಳಿಂದ ಪ್ರತ್ಯೇಕವಾಗಿ ಸಂಗ್ರಹಿಸಬೇಕು. ಈ ಉತ್ಪನ್ನದ ಶೆಲ್ಫ್ ಜೀವನವು ಎರಡು ವರ್ಷಗಳು.

| Food Category | Maximum Usage (as Cu) | ಟಿಪ್ಪಣಿಗಳು |
|---|---|---|
| Infant Formula Milk Powder | 3–12 mg/kg | Varies depending on product type for different groups |
| Infant Formula Food | 0.1–0.6 mg/100kJ (or 1.2–7.0 mg/100kcal) | Must strictly comply with stage standards |
| Older Infant & Young Child Formula Food | 0.2–1.2 mg/100kJ (or 1.2–7.0 mg/100kcal) | Must strictly comply with stage standards |
| Maternal Formula Milk Powder | 3–15 mg/kg | — |
| Beverages | 1–2 mg/kg | For solid beverages, increase proportionally according to dilution ratio |
| Instant Cereals | 3–10 mg/kg | Such as oatmeal, breakfast cereals |
Conversion:
If the dosage of Copper Sulfate (CuSO₄·5H₂O) is required, it should be calculated based on molecular weight.
The copper content in copper sulfate pentahydrate is approximately 25.5%.
ಆದುದರಿಂದ, if 1 mg of copper needs to be added, ಸುಮಾರು 1 / 0.255 ≈ 3.9 mg of food-grade copper sulfate is required.
