    Abstract: The present work was conducted to evaluate the quality of milk (fresh/acidic/neutralized) on the physico-chemical, textural and fatty acid profile of khoa prepared from buffalo milk and stored in poly-alu-poly laminates for 30 °C/7 days and 5 °C/21 days, ...

    Abstract The present work was conducted to evaluate the quality of milk (fresh/acidic/neutralized) on the physico-chemical, textural and fatty acid profile of khoa prepared from buffalo milk and stored in poly-alu-poly laminates for 30 °C/7 days and 5 °C/21 days, respectively. The degree of deterioration of common quality parameters was rapid during storage at 30 °C as compared to storage at 5 °C. Khoa stored at 30 °C showed greater variation in various physico-chemical and textural parameters as compared to khoa stored at 5 °C. Acidity, ash, tyrosine value, furosine, HMF, FFA, peroxide value, TBA value, butyric acid and stearic acid showed an increasing trend whereas, decrease in pH and oleic acid was observed as storage period progressed. Noticeable changes were observed in textural attributes of khoa during storage. However, the SDS–PAGE pattern of caseins from different types of khoa showed almost negligible deviation during storage.

    Abstract The present study was carried out to evaluate the effect of developed acidity and subsequent neutralization of milk (cow/buffalo) on heat induced protein–protein interactions occurring at various stages during khoa preparation. Protein–protein interactions were studied in terms of surface hydrophobicity (Fmax), sulfhydryl (–SH) group and SDS PAGE. As milk progressed to boiling stage, increase in Fmax and decrease in –SH content was observed. Khoa prepared from cow milk had comparatively higher values for Fmax and lower values for –SH group. Fmax was observed to be highest in acidic samples followed by neutralized and fresh samples. While considering –SH group, maximum values were observed in neutralized samples followed by acidic and fresh samples of both milk and khoa. However, no visible difference was observed in SDS PAGE patterns of casein fractions isolated from different types of samples. The bands of β-lg and α-la did not resolve clearly in the khoa samples due to high heat treatment involved in its preparation, indicating intense denaturation of whey proteins especially in neutralized samples where an alkaline medium resulted in strong binding between casein and whey proteins. The quality of milk also resulted in altered heat induced protein–protein interactions in khoa.

    Abstract Glycomacropeptide (GMP) is a nutraceutical additive, which is released during cheese preparation. In this study, the protein content in a laboratory GMP preparation and two commercial GMP samples, which was estimated by the Bradford, biuret, Lowry and bicinchoninic acid (BCA) assays, were compared using the Kjeldahl method. There were apparent differences in the values of estimated proteins using the different methods. An absence of dose response in the Bradford method and a low dose response using the Lowry method indicated the unsuitability of both these methods. Absorbance in the biuret and BCA methods linearly increased with increasing GMP content. The BCA method was the most sensitive of these methods.
