Study of relations between chemical, colour and fluorescence properties of raw and dried meat powders of cow and yak (Bos grunniens)

Cıldızay ÖZBEKOVA | Asılbek KULMIRZAYEV

Gluteus medius, Longissimus thoracis, and Semitendinosus muscles from the cow and yak (Bos grunniens) reared in the Kyrgyz Republic were dried by convective (hot air) drying and freeze drying. The dried muscles were grinded into fine powders and along with raw muscles were evaluated for water activity (aW), chemical composition (moisture, fat, protein), colour characteristics (L, a, and b values), fluorescence of intrinsic fluorophores (tryptophan, vitamin A, and riboflavin). Processing of measured data tables using common components and specific weights analysis (CCSWA) showed close relations ...Более

Study of moisture content and water activity of rice using fluorescence spectroscopy and multivariate analysis

Cıldızay ÖZBEKOVA | Asılbek KULMIRZAYEV

The potential of fluorescence spectroscopy for non-destructive and rapid measurement of moisture content (MC) and water activity (a(W)) of rice was examined. A total of n 15 samples of rice produced at different locations were studied. The emission fluorescence spectra of tryptophan (305-600 nm, excitation: 290 nm) and emission fluorescence spectra of riboflavin (410-700 nm, excitation: 370 nm) were collected from milled rice. MC and a(W) of the rice samples were measured. Spectral data were subjected to principal component analysis (PCA) and partial least squares discriminant analysis (PLSDA) ...Более
