Sugar profile in dairy formulations
Compare lots using one analytical method. Ask for source and allergen documentation.
Powder-to-syrup substitution
Normalize to dry GOS first. Compare residual lactose, glucose and water introduced to the formula.
Purchase specifications and incoming inspection
Include the intended grade or current specification in the enquiry. Use the table to compare selection criteria and inspection conditions. The specification agreed by both parties defines the contractual limits. ENVO · Galacto-oligosaccharides product information ↗
| Property | Unit | Published or agreed specification | Test conditions and checks |
|---|---|---|---|
| GOS content | % on a dry basis | The public catalogue distinguishes grades including 57% and 70%. | Identify the powder or syrup grade and the chromatographic peaks included in integration. |
| Total solids | % by mass | Request an as-received measurement | Record sampling temperature and analytical method. Verify any conversion from refractometer readings. |
| Syrup dry matter | % by mass | ENVO syrup example: 74.0–76.0%. | Compare the two catalogue syrup grades, 57 and 70. Use the measured moisture content for powders. |
When approving a sample, record the grade, methods, limits and specification revision. On receipt, match the packing lot number to the lot-specific COA and record the measured values and release decision.
From samples to commercial delivery
Packaging and receiving
Record net mass and solids for syrup, or bag net weight and moisture for powder. Use form-specific receiving records.
Storage and handling
Order powder and syrup separately. Check dry matter, net weight and origin declaration; for liquid also check closure and receiving tank.
Sample and order lead times
State food category, sales market, pilot quantity and required arrival date. Confirm MOQ, batch documents, availability and remaining shelf life separately for samples and commercial orders.
Questions from the plant
How can we check both target oligosaccharides and the actual sugar contribution?
Compare batches using the same analytical method. Request raw-material origin and allergen documentation.
Is the name GOS sufficient for allergen review?
Obtain source, milk constituent and cross-contact declarations from the supplier. Link them to the lot submitted for approval.
Report a delivery or batch issue
Include the order number, lot number from the package, label photos and inspection records for the affected lot. When retesting, check GOS assay method, lactose and monosaccharides, dry matter.
