| description | Malting process leads to changes in the protein content and protease activity of cereal crops. Total protein content and soluble protein content are important indicators of the quality of cereal crops, as they can affect the digestibility and bioavailability of the proteins for human consumption. Protease activity is also important, as it can influence the breakdown and release of amino acids from proteins, which are essential for human nutrition. The study aims to investigate how the total and soluble protein content and protease activity change during the production of malted wheat and barley flours at different germination times (0, 1, 2, 3, and 4 days). The findings indicated that during malting there was an increase in the amount of soluble proteins and protease activity in both wheat and barley. Although the total protein content did not change significantly, the increased amount of soluble proteins suggests that the malting can improve the nutritional value of the cereal crops. Moreover, the increase in protease activity with the extension of the germination time suggests that there is an optimal time for germination that could maximize the nutritional benefits of the malting process. Investigation revealed barley had a higher content of total and soluble proteins and higher protease activity compared to wheat. The outcomes of this study could be valuable for optimizing the malting process for maximum nutritional benefits, and for developing new better nutritional products. |
