Description

  The present invention relates to a cooked rice-like food. More specifically, the present invention relates to a new cooked rice-like food that has a texture of cooked rice and is low in calories and hardly aged.

  Rice is a Japanese staple food. However, in recent years, changes in dietary habits have been seen due to adult diseases such as obesity and diabetes, diet orientation, etc., and rice consumption has been steadily decreasing. However, after all, the staple food of Japanese is rice, and there are many people who cannot wipe out the desire to eat a lot of rice during meals. In addition, allergic disease patients and kidney disease patients may not be able to take rice.

In order to solve those problems, it has a composition of starch 20% by weight or less, dextrin 20% by weight or less, gelling agent 0.1 to 7% by weight, cellulose 1 to 20% by weight and moisture 40 to 90% by weight. Although low-calorie artificial rice such as rice-like food (Patent Document 1) characterized by having an appearance and texture for cooked rice is provided, it contains carbohydrates such as starch and dextrin, It cannot be said that the reduction is sufficient. In addition, especially at convenience stores and supermarkets, rice balls and rice are often sold refrigerated, and thus there is a problem that aging occurs due to the inclusion of starch.
JP-A-6-46773

  The present invention has been made for the purpose of providing a new cooked rice-like food that has a low-calorie rice-like texture and is less likely to age.

  As a result of intensive studies to solve the above problems, the present inventors have found that in cooked rice-like foods, a specific amount of dietary fiber material, a specific amount of native gellan gum, a specific amount of agar and / or gellan gum and / or Cooked rice-like foods that contain thickening polysaccharides other than kappa carrageenan, specific amounts of native gellan gum, agar, gellan gum, and kappa carrageenan have found low-calorie, cooked rice-like foods that have a cooked rice-like texture. The present invention has been completed.

  That is, the first of the present invention is at least one selected from the group consisting of 2 to 40% by weight of dietary fiber material, 0.2 to 3% by weight of native gellan gum, agar, gellan gum and κ carrageenan in the whole cooked rice-like food. 0.2 to 2 wt%, native gellan gum, agar, gellan gum, 0.2 to 7 wt% thickening polysaccharide other than kappa carrageenan, 45 to 91 wt% water, and 0 to 3 wt% starch. It relates to a cooked rice-like food characterized by that. A preferred embodiment relates to the cooked rice-like food as described above, wherein the dietary fiber material contains cellulose. The second of the present invention is a cooked rice mixture comprising (A) cooked rice-like food and (B) cooked rice and / or ingredients as described above, wherein the weight ratio ((A) / (B)) is It is related with the rice cooking rice mixture characterized by being 5 / 95-95 / 5.

  By using the present invention, a cooked rice-like food having a low-calorie rice-like texture and less likely to age can be provided.

  Hereinafter, the present invention will be described in more detail. Dietary fiber materials that can be used in the present invention include foods such as cellulose, polydextrose, indigestible dextrin, guar gum enzyme degradation product, low-molecular sodium alginate, psyllium seed coat, inulin, water-soluble soybean polysaccharide, gum arabic, and corn fiber. It is a fiber material. However, even if it is a dietary fiber, the thing which reacts with other thickeners etc. which are remarkably thickened like glucomannan etc. is not included. The addition amount of the dietary fiber material is preferably added in the range of 2% by weight to 40% by weight in the whole cooked rice-like food. If the added amount is less than 2% by weight, the texture may become watery, and if it is more than 40% by weight, the texture may become heavy. In any case, the texture does not match the texture of the cooked rice-like food. Moreover, in order to put out the white color close | similar to cooked rice, it is preferable to contain a cellulose. In this case, the content of cellulose is preferably 0.5 to 10% by weight, more preferably 0.5 to 5% by weight, and still more preferably 0.5 to 2% by weight in the whole cooked rice-like food. If the cellulose content is less than 0.5% by weight, the color may be too light, and if it is more than 10% by weight, the glutinous texture may be impaired.

The native gellan gum of the present invention is generally obtained by the following production method by culturing microorganisms. Specifically, Pseudomonas elodea (ATCC31461) or an equivalent strain thereof, for example, glucose: 3%, KH ₄ NO ₃ : 0.05%, MgSO ₄ .7H ₂ O: 0.01%, NH ₄ NO ₃ : Inoculated into a liquid medium containing 0.09% and a small amount of organic components as a nitrogen source, and cultured on an aerobic condition at about 30 ° C. for about 50 hours. Native gellan gum can be obtained by isolating and recovering the mucilage produced in 1) without deacylation. Since native gellan gum has a natural origin, its structure can change slightly depending on the production microorganism used and the purification conditions. Therefore, the native gellan gum used in the present invention is not limited based on a specific structural formula (Sanderson, GR, FOOD GELS, ed. Peter Harris, Elsevier Science Publishers LTD., England, 1990, p.204). Any native gellan gum produced by a microorganism (ATCC 31461) according to the above method may be used. However, if the thickening polysaccharide obtained by the same production method using other strains has the same physical properties as native gellan gum, they may be used. The amount of native gellan gum added is preferably in the range of 0.2 wt% to 4 wt% in the whole cooked rice-like food. If the addition amount is less than 0.2% by weight, the elasticity may be low, and if it is more than 3% by weight, the elasticity may be too strong. In any case, the texture of the cooked rice-like food is not suitable. .

  The agar of the present invention can be extracted from seaweeds of red algae such as sea cucumbers, Amakusa, and buckwheat with hot water and dried through filtration, gelation, dehydration and drying. The gellan gum of the present invention is obtained by deacetylating native gellan gum (Moorhouse, R., Colegrove, GT, Sandford, PA, Baird, JK and Kang, KS: ACS Symp., Ser., 150, In "Solution Properties of Polysaccharides "(Brant, DAed.), P.111, 1981. Although native gellan gum and gellan gum are similar in structure, their properties as thickeners and gelling agents are completely different. Is a different gum. The kappa carrageenan of the present invention is a kind of red polysaccharide-derived acidic polysaccharide (carrageenan) having a repeating structure of β-D-galactose and 3,6-anhydro-α-D-galactose as monomers. Carrageenans are mainly classified into three types, κ-type, ι-type, and λ-type, depending on the position of the sulfate group and the presence or absence of an anhydro sugar, and α-D-galactose is preferably used in the present invention. It is a κ-type carrageenan having a sulfate group bonded to the C4 position. It is preferable that at least one selected from the group consisting of the above-mentioned agar, gellan gum, and kappa carrageenan is contained in the cooked rice-like food of the present invention, and the addition amount is 0.2% by weight to 2% in the whole cooked rice-like food. It is preferable to add in the range of% by weight. If the added amount is less than 0.2% by weight, it may be softer than cooked rice, and if it is more than 2% by weight, it may be too hard than cooked rice. In either case, it does not match the texture of the cooked rice-like food. .
