ABSTRACT
Objective:
To establish microbiological method for determining biotin in foods and feeds.Methods:
Using biotin dependent microorganisms Lactobacillus plantarum(ATCC 8014), the biotin content was detected indirectly by the growth of cultrued bacteria spectrophotometrically.Results:
The detection limit was 0.03 ng. The relative standard deviations(RSD) of within and between run assays were 2.2%-3.8%,2.1%-5.3% respectively. The recovery of added biotin was 93.4%-104.6%, and RSD was 3.1%-4.1%.Conclusion:
This assay is sufficiently accurate and repoducible for determining biotin in foods and feeds.
