Start with the finished food
A sauce manufacturer, a seasoning blender and a meal-kit packer may all ask for dehydrated garlic but need different ingredients. Before requesting a quotation, describe the finished product, whether garlic pieces should remain visible, and when the ingredient enters your process. Include mixing, cooking and holding conditions used in your own trial. A product name alone leaves too much room for interpretation.
Shortlist a form by its job
- Flakes are a starting point when recognisable pieces matter. Check their appearance after your actual preparation process, rather than judging only a dry handful.
- Granules are worth testing when you want a measurable particle texture in a blend or topping. Specify the size distribution and check how the ingredient mixes with the other components.
- Powder is worth testing when visible pieces are unwanted. Check dispersion, dust during weighing, colour in the finished recipe and the dosing equipment you intend to use.
These are trial directions, not promises that one form will suit every application. If the product will be rehydrated, compare samples at the same water ratio, temperature and time. If it will be added dry, test it dry in the intended mixture.
Put particle size into writing
Words such as fine, coarse and premium are not a complete specification. For flakes, agree a size range and the permitted proportion of broken pieces. For granules and powder, ask which sieve standard is used, the opening sizes, and the percentage passing or retained. A mesh number without a test basis can make two quotations difficult to compare.
Keep a labelled sample alongside the written specification. Record its batch code and the date received, so the next discussion refers to an identifiable material rather than a photograph.
Compare performance at a fixed dose
Use the same recipe, equipment and garlic addition rate for the first comparison. Record aroma before and after processing, visible particles, texture, colour and any operational problems. Then adjust the dose if needed. This separates the cost per kilogram from the cost of achieving your required result.
For a dry seasoning, include a mixing and dispensing check. For a sauce, inspect the finished product after its normal holding period. Ask your team to describe an unwanted result precisely: noticeable particles, uneven distribution or excessive darkening is more actionable than simply saying the sample is unsuitable.
Separate moisture checks from safety checks
The CSIRO fact sheet hosted by USDA Agricultural Research Service explains that moisture content and water activity are different measurements. Ask for the measurement relevant to your specification and its test method; do not substitute one number for the other.
FDA’s spice risk profile documents microbial hazards in spices. A dry appearance therefore does not establish microbiological suitability. Ask about the applicable treatment, batch testing and handling controls, and agree acceptance criteria with your quality team for the intended use.
Send an RFQ that can be answered
- Product form and intended food application.
- Particle-size requirement and preferred test basis.
- Trial quantity, estimated order quantity and packing size.
- Ingredient declaration, treatment information and required batch documents.
- Storage requirements and desired remaining shelf life at receipt.
- Destination, delivery timing and any customer-specific specification.
If the size is undecided, say so and describe the result you need. Surge Garlic can use that brief to discuss suitable forms and sample requirements before a final specification and quotation are agreed.
