Do your food additives comply with national safety standards in China?
Yes. All products are manufactured in strict accordance with the National Food Safety Standard for the Use of Food Additives (GB 2760) and relevant product standards (e.g., calcium propionate meets GB 1886.28-2020). Our company insist each batch undergoes multi‑dimensional quality and risk testing before shipment, and inspection reports are available upon request.
Both calcium propionate and sodium propionate are mold inhibitors. How should we choose between them in practical use?
Both are highly effective and safe preservatives for food and feed. The main differences are:
Sodium propionate generally offers slightly better mold inhibition in feed preservation and does not interfere with chemical leavening agents, making it widely used in bakery products like bread.
A customer wants to achieve a bread shelf life of 30+ days. How should we design a preservation solution using calcium propionate combined with encapsulated sorbic acid?
To achieve a bread shelf life of over 30 days, the combination of calcium propionate and encapsulated (microencapsulated) sorbic acid is currently recognized as one of the most effective solutions in the industry. Using calcium propionate alone has limited effectiveness—even adding 2%–4% calcium propionate only extends bread shelf life to 5-9days. However, through proper combination and encapsulation technology, results far exceeding single preservatives can be achieved. The two preservatives exhibit a significant synergistic effect:
Calcium Propionate: Primarily inhibits mold and bacterial growth while stabilizing bread texture, and does not inhibit or kill yeast.
Encapsulated Sorbic Acid: Uses microencapsulation technology (with hot‑melt fat as the wall material) to coat sorbic acid, effectively preventing direct contact between sorbic acid and yeast, avoiding yeast inactivation, and ensuring normal dough fermentation. The sorbic acid is gradually released during the baking process, which does not affect the fermentation stage while continuously inhibiting microbial growth in the later stage.
How should Aspartame be stored after opening to maintain optimal performance?
Aspartame should be stored in a cool, dry, and well-ventilated warehouse, protected from direct sunlight. As aspartame may absorb moisture and cake in humid environments, the container must be tightly sealed after opening. Recommended storage conditions are: temperature not exceeding 30°C and relative humidity below 75%. Aspartame shows good stability in dry powdered beverage mixes and other dry products. Avoid contact with strong acids, strong alkalis, or high-temperature environments to prevent decomposition and loss of sweetness.
Aspartame has limited solubility in cold water (approximately 1% at 25°C). Direct addition often leads to slow dissolution, clumping, or floating. How can this be effectively improved?
Gentle Heating: The solubility of aspartame increases with temperature. It is recommended to dissolve it in water heated to 50–60°C. This significantly speeds up the dissolution process while avoiding temperatures that are too high (e.g., above 60°C), which could cause hydrolysis and loss of sweetness.
pH Adjustment: Aspartame is more soluble in acidic environments, with maximum solubility near pH 2.2. Before dissolving, you can add a small amount of edible acid (such as citric acid or malic acid) to the water to lower the pH. Then add aspartame, or add both simultaneously—both approaches can significantly improve the dissolution rate and extent.
Sprinkle Slowly and Enhance Mixing: When dissolving, sprinkle the aspartame powder slowly and evenly into the water to prevent clumping from adding it all at once. At the same time, strengthen the mixing process (e.g., using high‑speed stirring).
Pre‑mix with Dry Ingredients: Before dissolving, dry‑mix aspartame with a small amount of sugar, other powdered excipients, or stabilizers. This helps dispersion in water and prevents clumping.
How to prevent CMC from clumping in beverages? Why is the viscosity of my CMC solution unstable?
When dissolving, add CMC slowly and evenly into water under high‑speed stirring, avoiding adding a large amount at once. It can also be mixed with a small amount of dry powder such as sugar before dissolving.
B: Viscosity instability may be related to pH, temperature, or electrolytes. CMC has the highest viscosity at pH 6–9, and prolonged high‑temperature storage or high salt content may cause its degradation.
What key parameters are needed for a price quote for CMC (Carboxymethyl Cellulose)?
Please provide the following core parameters, as they directly affect pricing:
Viscosity – the most critical property (thickening, suspension, water retention). State your target viscosity range.
Test Concentration – viscosity must be measured at a specified concentration (usually 1% or 2% w/v). Values at 1% are much lower than at 2%. Please specify which concentration you require.
Degree of Substitution (DS) – affects solubility, clarity, and acid resistance. High DS (≥0.9) for clear beverages; low DS (0.5–0.7) for non‑clear systems. State your required DS range.
Can you cooperate with pre‑shipment inspections before loading?
Yes, we fully support customers’ pre‑shipment inspection requirements and have extensive experience in this area. We understand that pre‑shipment inspection is a critical step in ensuring product quality, protecting customer interests, and ensuring smooth international trade. Our services include:
PVOC (Product Verification of Conformity) : We have solid experience cooperating with PVOC inspections required for East African countries such as Kenya and Uganda. We are familiar with the entire PVOC certification process and can assist customers in obtaining the CoC (Certificate of Conformity).
Customer‑Designated Third‑Party Inspections: We can cooperate with any qualified third‑party inspection agency designated by the customer, including on‑site sampling, laboratory testing, and sample retention.
