Flour Type 405

Availability and types of Flour Type 405

Origin:
Flour Type 405 is usually made from wheat, specifically from a variety called soft wheat. During milling the hard outer shell (bran) and the germ are almost entirely removed, leaving mainly the white interior of the grain, which makes Flour Type 405 very light and fine. The name “405” indicates how much mineral matter remains as ash after burning the flour – at 405 it is very little, which is why the flour appears almost white. You can imagine it like this: the lower the number, the “whiter” and finer the flour is.

Growing regions:
Wheat for Type 405 grows in many parts of the world. Important regions include:

For us in the supermarket it is often not important which exact country the flour comes from, but farmers in these regions grow wheat because the climate (not too hot, not too dry) is suitable.

Available types and variants:
Although “Type 405” describes a certain lightness and fineness, there are different variants you can buy. Here are some simple examples:

Simple comparison:
Imagine flour as sand: Type 405 is like very fine, white sand, perfect for delicate constructions (cakes). Coarser flours like Type 550 or wholemeal are more like coarser sand or gravel, better for strong structures (bread).

Availability:
Flour Type 405 is available almost everywhere: supermarkets, bakeries, corner shops, health food stores and online. It is sold in small packages (500 g, 1 kg) and in large sacks for bakers. If you want to know exactly where your flour comes from, you can check the label: it often states the country of origin, whether it is organic and which additives (if any) are included.

Thus Flour Type 405 is a very common, light wheat flour characterized by its fine texture and available in various variants – from organic to freshly milled or as baking mixes – and is easy to obtain.

Flour Type 405 is a widely used, finely milled wheat flour in Germany, characterized by a low mineral content and a pale color. The type number 405 indicates the ash content in milligrams per 100 grams of dry matter and corresponds to an ash proportion of about 0.405 %. It is mainly a flour milled from the inner endosperm of the wheat grain, with bran and germ largely removed.

Composition and nutritional values
Chemically, Type 405 mainly consists of starch (a polymer of amylose and amylopectin), complemented by water-soluble carbohydrates, proteins (especially gluten proteins), small amounts of lipids and traces of minerals and vitamins. Typical nutritional values per 100 g of flour are approximately in the following ranges:

These values should be understood as averages; exact contents vary with grain variety and batch.

Processing and physical properties
In milling for Type 405 the harder outer grain layers are separated, resulting in a particularly fine and light product. The low fat content due to removal of the germ extends shelf stability compared with wholemeal flours. Typical characteristics are the fineness of the flour particles, a relatively high water absorption compared with very starch-rich flours and a moderate gluten quality. The starch granules typically gelatinize during heating in a temperature range of about 60–75 °C, which gives structure to baked goods.

Baking-technical aspects
Type 405 is preferred for fine baked goods such as cakes, pastries, light rolls and sauces. The moderate to low protein content results in a tender crumb and lower gluten strength than bread flours. For yeast-based breads or very extensible doughs, flours with a higher protein content (e.g. Type 550 or bread flours) are often used. Laboratory chemical parameters such as the farinograph water absorption profile or the alveograph are used to assess baking properties, providing information on mixing behavior, elasticity and extensibility of the gluten.

Health aspects
As a refined flour, Type 405 contains comparatively few fibers, vitamins and trace elements compared with wholegrain products, since bran and germ are largely removed. The lower phytic acid load can mean better mineral availability, however useful secondary plant compounds are also missing. People with celiac disease or wheat allergy must avoid gluten-containing flour; for the general population moderate consumption as part of a balanced diet is common. Because of the high starch content this flour has a relatively high glycemic index, which is relevant for blood sugar management.

Storage and quality
Proper storage in dry, cool and dark conditions prevents microbial infestation and quality loss. Due to the low fat content Type 405 is less prone to rancidity than wholegrain flours, yet long storage times should still be avoided as aroma and baking properties decrease over time.

Overall Flour Type 405 is a versatile, technically well-described product for fine baked goods and classic kitchen applications. Its physical and chemical properties result from the targeted removal of outer grain material during milling, producing pale color, fine texture and specific baking properties, while nutritionally the reduction of fiber and micronutrients should be taken into account.
