Oat bran
Oat bran or oat bran is a special mill product consisting of oat kernels (see Oat ) is produced for human consumption. Oat bran should not be confused with the husks , which are a by-product of the mill. Oat bran is formed when the aleurone layer (thin skin that surrounds the inner endosperm), the outer layers of the grain ( seed peel, fruit peel) and the seedling are primarily processed from the oat kernel .
Health importance
The calorific value of oat bran is 1298-1470 K J (309 and 350 kcal ) per g 100th
Since oat bran consists primarily of the nutrient-rich components of the oat grain, the nutrient content is higher than in other whole-grain oat products. Therefore, oat bran is suitable for a balanced diet in which attention is paid to the supply of nutrients. With 8.1 grams per 100 grams, oat bran contains almost twice as much beta-glucan (soluble fiber ) as oat flakes. Therefore, oat bran is particularly recommended for maintaining normal cholesterol levels or lowering high cholesterol levels. The ability of oat beta-glucan to bind bile acids leads to the excretion of cholesterol, which leads to a lowering of both total and LDL cholesterol levels. Oat beta-glucan forms a viscous consistency in the stomach and small intestine, which results in a slower absorption of the nutrients from the gel-like mass. This leads to a less pronounced and time-delayed rise in blood sugar levels .
Oat bran can be used in muesli as well as in yogurt and quark dishes. However, it can also be used for hot dishes as well as in pastries and cakes. When using oat bran in the human diet, care should be taken to ensure adequate fluid intake, as otherwise, as is generally the case with high-fiber foods, constipation can occur.
Legal provisions
The EU regulation on nutrition and health claims (Health Claims Regulation) stipulates that ready-to-eat foods containing at least one gram of oat beta-glucan per serving may be advertised as having a cholesterol-lowering effect. To do this, they must be told that a total of three grams of oat beta-glucans are required per day. With four tablespoons of oat bran (40 grams) you get 3.2 grams of beta-glucan.
Possible health claims according to the community list of admissible health-related claims published in 2012 in accordance with Article 13 paragraph 3 of the Health Claim Regulation can be:
| Nutrient / substance / food | Information (VO 432/2012) | Conditions for use (VO 432/2012) |
|---|---|---|
| Beta glucans | "Beta-glucans help maintain normal cholesterol levels in the blood" | “The information may only be used for foods that contain at least 1 g beta-glucans from oats, oat bran, barley or barley bran or from mixtures of these cereals per given portion. In order for the claim to be permissible, consumers must be informed that the positive effect is obtained with a daily intake of 3 g beta-glucans from oats, oat bran, barley or barley bran or from mixtures of these cereals. " |
| Beta-glucans from oats and barley | "The inclusion of beta-glucans from oats or barley as part of a meal helps reduce the rise in blood sugar levels after the meal" | “The claim may only be used for foods that contain at least 4 g beta-glucans from oats or barley per 30 g available carbohydrates in a given portion as part of the meal. In order for the claim to be admissible, consumers must be informed that the positive effect occurs when beta-glucans from oats or barley are included as part of the meal. " |
| Oat grain fiber | "Oat grain fiber helps increase stool volume" | "The claim may only be used for foods that have a high content of this dietary fiber in accordance with the claim HIGH FIBER CONTENT listed in the annex to Regulation (EC) No. 1924/2006." |
