<div>Background: Biogenic amines (BAs) are low molecular weight organic bases with biological activity that are formed in foods by microbial decarboxylation of the corresponding amino acids or by transamination of aldehydes and ketones by amino acid transaminases. As these BAs are toxic and act as a spoilage indicator, their presence determines the quality of food. 
 
Methods: Milk and selected milk products were assessed for the presence of selected BAs such as histamine, tyramine, tryptamine, spermine, spermidine, cadaverine and putrescine using HPTLC.&nbsp; 
 
Result: It was observed that histamine, spermidine and tryptamine were present in the raw as well as pasteurized milk of cow and buffalo. Pasteurised milk found to show low concentration of tryptamine than the raw milk. Cheese was found with the presence of histamine, tryptamine and putrescine throughout the storage. Though, BAs are present within safe limit in all the milk and selected milk products but their presence indicates a serious quality concern.&nbsp;</div>

Assessment of Biogenic Amines in Milk and Selected Milk Products

<div>Background: Gauri takra (GT) was found to be an excellent refreshing drink. The current investigation attempts to assess the phytochemical identification and antioxidant properties of Gauri Takra. 
 
Methods: According to the standard procedures, the food recipe GT was examined for phytochemical identification, total flavonoids, total phenolic content, in vitro radical scavenging assays and HPTLC analysis. 
 
Result: High-Performance Thin-Layer Chromatography analysis of the methanolic extract of GT has been screened for phytochemical identification. The qualitative test revealed that the methanolic extract of GT contained the presence of quercetin and their Rf value was 0.62 and the 6-gingerol Rf value was detected as 0.68. The phenolic content of GT was 2.69&plusmn;0.02 mg TAE/gm and a total flavonoid content of 4.35&plusmn;0.34 mg QAE/gm. Aqueous extract of GT were investigated for their antioxidant properties using DPPH, FRAP and ABTS&bull;+&nbsp;radical scavenging assay. There was a significant dose-dependent inhibition of in-vitro radical scavenging assays as demonstrated by the aqueous extract of GT. Thus, our results show that GT was exhibited strongest antioxidant activity.</div>
