Alpha-Galactosidase Sample & Lab Report for Process Trials
For legume processors, plant-protein producers, feed mills and ingredient resellers: test a documented sample in your own process, then request a quote with product, quantity and destination.
Raffinose and stachyose in soybeans, lentils, chickpeas and soybean meal hold back digestibility and product quality, and alpha-galactosidase (EC 3.2.1.22) from Aspergillus niger is used to break them down. Before a production order, a buyer needs proof that the grade works on their own raw material, and that is what a sample with a lab report is for.
The first decision is the grade. Food-grade alpha-galactosidase is sold for food processing, and its label names the food-enzyme standard it is made to. Feed-grade material is labelled for livestock and poultry feed and is made to the producer's own company standard, so the two grades are not interchangeable on paper even though the enzyme is the same.
Our grade works at pH 4.0–6.5 and 40 °C–55 °C, with 1,000–50,000 GalU/g, packed in 1 kg, 5 kg and 25 kg. Spec sheets from different producers print different pH and temperature windows for the same enzyme, so judge the lab report against your own process conditions rather than against another supplier's headline figure. Send your substrate, process target and the quantity you expect to buy after the trial, and the sample, report and bulk quote are prepared together.
Bean and legume processing trials
Use alpha-galactosidase to reduce raffinose and stachyose in soybeans, lentils, and chickpeas during soaking, cooking, or pre-treatment trials. A sample enables process engineers to confirm oligosaccharide reduction under actual plant conditions before scaling up. Evaluations typically focus on enzyme activity, dose response, and retention after heat exposure to ensure fit with line speed and quality targets.
Low-FODMAP bakery development
Bakery formulators apply alpha-galactosidase in extended fermentation systems to lower FODMAP content in sourdough and related doughs. A lab report sample provides activity verification across pH 4.0–6.5 and 40 °C–55 °C. Technical buyers can compare reduction performance, batch consistency, and stability before approving pilot or commercial orders.
Plant-based protein ingredient validation
Producers of plant-based meat and dairy alternatives use alpha-galactosidase to improve digestibility and flavour in legume-derived protein systems. Sampling supports lab screening for pre-treatment of concentrates, isolates, and slurries where galacto-oligosaccharides affect tolerance and functionality. Documented activity data allows procurement to match the grade to required dosage and process windows.
Soybean meal and feed premix trials
Feed-grade alpha-galactosidase is labelled for livestock and poultry feed and targets the alpha-galactosides in soybean meal, mainly raffinose. The label instruction is to mix it in thoroughly: premix the powder with a small amount of feed first, then blend that premix into the main batch. Feed grade is packed in 25 kg bags, with 1 kg bags alongside, so a mill can run its trial on a small bag before ordering full bags.

Frequently Asked Questions
What should a procurement team look for in an enzyme sample?
An enzyme sample should be accompanied by a clear lab report listing declared activity, appearance, storage recommendations, packaging, and shelf life. Confirm that the activity range aligns with your intended process parameters, especially for beans, legumes, sourdough, or soy feed. A well-documented sample allows QA and production teams to test under real conditions before committing to bulk orders, reducing approval risk and shortening the supplier review cycle.
How is alpha-galactosidase typically used in process trials?
Alpha-galactosidase is evaluated in soaking, fermentation, slurry, or pre-treatment trials aiming to lower raffinose-family oligosaccharides. The common working window is pH 4.0–6.5 and 40 °C–55 °C, with dosage determined by substrate load, residence time, and target reduction. During lab trials, multiple enzyme levels may be compared to identify the most efficient dose. The lab report should support these decisions with consistent, reliable activity data.
Can I request an enzyme sample before placing a production order?
Yes. Requesting a sample before commercial approval is standard for technical buyers. It allows laboratories to verify activity, handling behaviour, and process suitability without full-order risk. A sample lab report adds value when comparing grades, checking specification fit, or documenting results for internal procurement and QA review. This practice is common in ingredient qualification and process validation.
What information should the lab report include?
The lab report should cover enzyme identity, EC number, activity range, appearance, storage recommendation, shelf life, and packaging. Including source organism and recommended working conditions helps technical teams align the sample with trials. If pH, temperature, or residence time drive application success, these parameters should be clearly presented for easy reference.
Is this alpha-galactosidase suitable for food and feed applications?
This grade is designed for industrial food and feed processing, including bean and legume treatment, bakery fermentation, plant-based protein systems, and soy meal applications. Buyers often verify food-grade status, certifications such as HALAL and KOSHER, and pack sizes during sourcing. A sample trial confirms whether the enzyme performs as required in your formulation and process equipment, subject to compliance and validation results from your own lab or pilot line.
Should we ask for a food-grade or a feed-grade sample?
Ask for the grade that matches your finished product. Food grade is supplied for food processing, and its label carries the food-enzyme standard. Feed grade is labelled for livestock and poultry feed and is made to a company product standard. A feed-grade lot cannot go into a food product, so name the end market in your inquiry.
How do we compare activity figures from different suppliers?
Feed-grade labels, for example, give activity as a minimum value per gram, not as a typical value. Ask for the assay method with each lab report.
How should the sample be stored when it arrives?
Keep it sealed in the original pack in a cool, dry place out of direct sunlight; labels treat alpha-galactosidase as a biologically active material and give storage conditions for that reason.
