Description

The present invention relates to a dietary textile product.

(Prior art)

Recently, dietary fiber has been used to prevent obesity, reduce obesity, improve carbohydrate metabolism, improve lipid metabolism, improve physiology of the digestive tract such as promoting bowel movement, prevent gallstones, prevent colorectal cancer, reduce toxicity of harmful substances, etc. Has been shown to be effective, and its importance has been reaffirmed. However, in recent years, the dietary fiber intake has tended to decrease with the westernization of dietary habits, and the necessity of dietary fiber intake has been called out. And, for the purpose of supplementing the insufficiency of ingestion of dietary fiber, it is possible to ingest inexpensive wheat bran, rice bran or other rice bran as it is or in addition to other foods, containing a relatively large amount of dietary fiber. It is being carried out (Japanese Patent Publication No. 62-16621).

By the way, when bran such as wheat bran is eaten as it is or added to other foods, it is necessary to ingest a large amount of bran in order for it to function effectively as a dietary fiber. However, rice bran, such as wheat bran, is inferior in taste, as is clear from the fact that it has been widely used as animal feed rather than human food, and it is difficult to consume them in large quantities. It was difficult.

The present inventors have been conducting various studies on more effective dietary fiber, and on the treatment and effective use of wheat bran containing a large amount of dietary fiber.One of such studies is to grind wheat bran. A method for efficiently obtaining each of the high fiber content category and the low fiber content category (high protein category) by classification was proposed and proposed earlier (Japanese Patent Application Laid-Open No. 1-206962 and Japanese Patent No. 2549411).

Separately, untreated bran 95 of Example 1
Parts by weight, 1 part by weight of a vitamin mixture and 4 parts by weight of a mineral mixture (hereinafter referred to as "untreated bran mixed with BM") Seven groups of 35 rats each weighing 90 to 110 g, each having 5 rats The rats were divided into I to VII (the average weight of rats in each group was 100 g / animal), and each group was fed a diet having the composition shown in Table 3 below in the amount shown in Table 3 for 35 days. Was examined for increased body weight (increased body weight). Table 3 shows the results.

The energy intake in Table 3 was calculated by multiplying the crude protein content (g), crude fat content (g), and carbohydrate content (g) per 100 g of feed by the respective energy conversion coefficients.

In other words, for wheat bran, the energy conversion factor proposed by FAO is calculated using protein 1.82, lipid 8.37, and carbohydrate (fiber + carbohydrate) 2.35. For other feed ingredients, protein conversion factor is Atwater's energy conversion factor. Calculated using 4, lipid 9, and carbohydrate 4.
By the way, according to the calculation method of such energy, the above feed MF is 360Kcal / 100g, BM mixed C category is 231Kcal / 10
Untreated wheat bran mixed with 0 g and BM is 213 Kcal / 100 g.
