This work aim to verify the importance of milk thistle seed powder (MTSP) as a medicinal plant and effect of fortification wheat flour (WF) with MTSP on chemical and nutritional properties. Therefore, the chemical composition such as ether extract, dietary fiber, crude protein, vitamin C, amino acids and minerals contents were determined. Also, the antioxidative properties such as phenolic compounds and flavonoid compounds and scavenging activity on DPPH free radicals were also determined. Furthermore, the possibility to use MTSP in bread sticks preparation, where the use of MTSP as replacer of WF at different extents (4, 8 and 12%) to prepare bread sticks rich in protein and minerals, as well as organoleptic evaluation of prepared bread sticks were investigated. Results indicated that MTSP have high amount of protein (25%), ether extract (25.56%), crude fiber (29.68%), minerals content (4.55%), vitamin C (4.59 mg∕g), flavonoids (20,65 mg/g), and phenolic compounds (40.33 mg as Gallic /g) (antioxidants) which, could be used as alternative natural source for synthetic antioxidants in industry. The indispensable and dispensable amino acids are more abundant in MTSP protein. Sensorial evaluation of the obtained products indicated that successful replacement was 4, 8 and 12% of MTSP. So, it could be recommended to use the investigated plant seeds in bread sticks production for its nutritional concept and antioxidative effects. Finally, the use of inexpensive available natural sources of bioactive material and incorporated to our low-cost foods for treatment or protection of our widespread disease is innovated road to produce low price therapeutic foods available to wide levels of our people.
As part of this functional food covenant, the world is searching for new healthy food products with ample quantities of bioactive components such as fibre, mineral elements, essential amino acids, and phenols. Since CHIA seeds powder has both nutritious and pharmaceutical properties, integrating it into pan bread may be beneficial to human health. The sensorial parameters of pan bread enriched with CSP, amino acids composition, and proximate compositions of the pan bread were investigated in this study by partially replacing wheat flour (WF) with CHIA seeds powder (CSP) at levels of 3 percent, 6 percent, 9 percent, and 12 percent. The addition of CSP to pan bread improved the mineral content of the bread. With only a minor depreciation in bread quality, CSP could partially replace WF 72 percent extraction in pan bread, increasing its nutritional value in terms of fibre, essential amino acids, and minerals. Sensorial evaluation revealed that pan bread supplemented with up to 12% CSP was acceptable to the panelists, with notable differences in crumb texture, appearance, crust color, crumb grain, taste, odor, and overall acceptability as compared to pan bread control. When compared to pan bread without CSP, the CSP mixture increased the mineral content, essential amino acid content, and nutritional properties.
