The refinement process typically includes:
Milling: Wheat grains are cleaned and conditioned to a specific moisture content before milling. This process separates the endosperm from the bran and germ. Modern milling techniques use roller mills, which break the grain into smaller particles, allowing for precise control over the granulation and texture of the flour.
Sieving and Purification: After milling, the flour is sieved to remove larger particles and bran specks. Purifiers and plansifters are used to ensure that only the finest particles pass through, resulting in a smoother, more consistent flour.
Bleaching and Aging: Some flours undergo bleaching to improve color and aging to enhance baking properties. Bleaching agents like benzoyl peroxide may be used, while aging allows for the natural oxidation of flour, improving gluten strength and dough elasticity.
Enrichment: Refined flour is often enriched with vitamins and minerals to replace nutrients lost during milling. This enrichment not only improves the nutritional profile of the flour but also enhances its functional properties in noodle making.
In recent developments, advances in flour refinement technology and ingredient processing have led to more consistent quality in alkaline noodles. Innovations in noodle-making machines also allow for better control over dough thickness and texture, enhancing the overall eating experience. Furthermore, understanding consumer preferences has led to formulations that balance traditional qualities with modern taste expectations.
In conclusion, making alkaline noodles involves a meticulous process and attention to key factors like protein content, dough strength, and starch viscosity. The addition of alkaline salts not only affects the noodles' pH and color but also enhances their texture and flavor. With advancements in technology and ingredient processing, particularly in flour refinement, the quality and consistency of alkaline noodles continue to improve, meeting the evolving demands of consumers.
