citrinin/oryza

Lovastatin is a main component of Monascus purpureus fermented red rice contributing to the lipid-lowering effect. Citrinin is a toxic fermentation by-product which can be found as a contaminant. An accurate, simple and rapid micellar electrokinetic capillary chromatographic method was developed for

A rapid, simple and effective method for the determination of citrinin in rice by UHPLC coupled to fluorescence detection has been developed and validated. Extraction of citrinin from rice samples was achieved by applying a QuEChERS-based extraction/partitioning process with water and acetonitrile,

OBJECTIVE In order to survey the natural occurrence of citrinin in Monascus products. METHODS A total of 114 samples with either solid or liquid phases, collected from markets or delivered by the food production factories were analyzed by HPLC for citrinin. RESULTS The results revealed that 68

Monascus pigments, which are produced by various species of Monascus, often have been used as a natural colourant and as traditional natural food additives, especially in Southern China, Japan and Southeastern Asia. The limitation of wide using Monascus pigment is attributed to one of its secondary

Red rice is a fermented product of Monascus spp. It is widely consumed by Malaysian Chinese who believe in its pharmacological properties. The traditional method of red rice preparation disregards safety regulation and renders red rice susceptible to fungal infestation and mycotoxin contamination. A

This study reports the fungal and bacterial metabolites associated with natural contamination of 38 composite samples of locally processed rice from five agro-ecological zones of Nigeria (AEZs). The samples were evaluated for the presence of microbial metabolites by LC-MS/MS. Among the identified
