SBA Detection: A Complete Guide to Hazards, Standards, Kits and Applications

SBA detection is essential for quality control of soybeans and soybean meal. SBA (Soybean Agglutinin) is a typical anti-nutritional factor that seriously affects intestinal health and growth performance of livestock. Therefore, SBA detection has become a necessary test item in feed industry.

1. Hazards of SBA

SBA is heat-stable and difficult to degrade. High residual SBA causes serious hazards:

1. Intestinal mucosal damageSBA binds to intestinal epithelial cells, damages villi structure, reduces nutrient absorption and causes diarrhea.

2. Growth inhibitionSBA reduces feed utilization efficiency, leading to slow growth and high feed conversion ratio.

3. Immune and organ disordersHigh SBA intake causes pancreatic hyperplasia, liver enlargement and weakened immunity.

4. Poor feed qualityUnder-processed soybean products usually contain high SBA, reducing feed safety.

2. National Standards for SBA Detection

There is no mandatory national limit for SBA, but strict internal control is widely implemented.The official standard method for SBA detection is:GB/T 40220-2021 Determination of Soybean Agglutinin in Plant Metabolites — ELISA MethodIndustrial reference: SBA ≤ 0.2 mg/g in qualified soybean meal.
