Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a novel powdered nutritional composition, more specifically, for use in children and the elderly who are unable to take regular meals, or patients before or after surgery. This invention relates to a powdered nutritional composition used for nutritional supplementation.

[Prior Art] Traditionally, oral feeding formulas and tube feeding formulas have been used as a method of nutritional support for children and the elderly who are unable to consume regular meals, as well as patients before and after surgery. Enteral feeding methods using parenteral nutritional supplements and enteral feeding methods using parenteral nutritional supplements are known.

The nutritional composition used in the former enteral feeding method must have well-balanced nutritional components and high calorie content, be easily digested and absorbed, and not cause diarrhea or abdominal distension. Therefore, it is usually mixed with various nutrients such as natural foods and their decomposed products to form a high-calorie, nutritionally balanced product containing proteins, carbohydrates, lipids, vitamins, minerals, etc. .

Among such nutritional compositions, powdered ones can be prepared by, for example, dissolving an emulsifier in lipids in advance, adding the emulsifier, proteins, carbohydrates, etc. to water, emulsifying the composition, and then drying with hot air. I can do it. The above proteins and emulsifiers are involved in stabilizing the emulsion, especially when the powdered nutritional composition is added to water and made into a liquid.
It is greatly involved in the emulsion stability of the liquid.

By the way, this kind of powdered nutritional group. In order to administer RLT products to patients, they are usually added to warm water to make a liquid, and then the prepared liquid is administered enterally orally or through a tube or catheter in the same manner as a static drip. therefore,
The preparation may be left at room temperature for several hours or stored at a low temperature for about 2 days until administration to the patient is completed. For this reason, the preparation liquid may undergo lipid creaming, oil odor removal, etc. at the time of preparation or when stored at room temperature or low temperature.
It is also necessary to maintain a homogeneous emulsified dispersion state to prevent precipitation of proteins.

[Problem to be solved by the invention] Under these circumstances, the present inventors first developed an ester of polyglycerin with a polymerization degree of 3 to 1O and a fatty acid as an emulsifier, and the ester bond thereof. have discovered a tube feeding composition using a polyglycerin fatty acid ester having a number of 1 to 10 (Japanese Patent Application Laid-Open No. 193928/1983);
The present invention provides a powdered nutritional composition containing protein and/or its decomposition products, carbohydrates, lipids, vitamins, and minerals as main components, which has superior emulsification and dispersion stability when added to water and made into a liquid form. It was done for the purpose of

[Means for Solving the Problem] As a result of intensive research to develop a powdered nutritional composition having the above-mentioned preferable properties, the present inventors have developed a powder containing succinic acid monoglyceride as an emulsifier in a specific proportion. m
We have discovered that when a certain substance is added to water and made into a liquid, it has superior emulsion stability of lipids and dispersion stability of tambata compared to conventional products, achieving the objective.Based on this knowledge, we have developed the present invention. It was completed.

That is, the present invention provides a powdered nutritional composition containing proteins and/or their decomposition products, carbohydrates, lipids, vitamins, and minerals as main components, in which 0.02 to 5.00% by weight of succinic acid monoglyceride is used as an emulsifier. Contains n@
It provides powdered nutritional supplements.

The present invention will be explained in detail below.

The succinic acid monoglyceride used in the composition of the present invention is obtained by further esterifying a fatty acid monoglyceride of glycerin and a fatty acid having 12 to 20 carbon atoms with succinic acid, and may be used alone or with other fatty acids. It may be used in combination with emulsifiers such as egg yolk phospholipids, monoglycerides, sucrose fatty acid esters, polyglycerin fatty acid esters, and organic acid monoglycerides other than succinic acid.

This succinic monoglyceride is present in the powder composition at 0.0
2-5. It is necessary to contain 0% by weight, preferably 0.50 to 3.00% by weight. If this content is less than 0.02% by weight, the effect of improving emulsion dispersion stability will not be sufficiently exhibited, and if it exceeds 5.00% by weight, the improvement in this effect will not be recognized much considering the amount.

The composition of the present invention is mainly composed of protein and/or its decomposition products, carbohydrates, lipids, vitamins, and minerals, and can sufficiently supply nutrients necessary for the human body.

The proteins and their decomposition products used in the composition of the present invention include those that are easily digestible and highly nutritious, such as chicken egg protein, milk protein, soybean protein, fish protein, meat protein, caseins, and enzymatic decomposition thereof. Examples include things. These evening bacteria and their decomposition products are 1
A seed may be used or two or more types may be used in combination, and the blending amount is usually selected within the range of 10 to 40% by weight based on the powder composition.

Examples of carbohydrates used in the composition of the present invention include starch, dextrin, monosaccharides such as glucose and fructose, and disaccharides such as maltose and lactose. One type of these carbohydrates may be used, or two or more types may be used in combination, and the blending amount thereof is usually selected within the range of 50 to 80% by weight based on the powder composition.

Examples of the lipids used in the composition of the present invention include fatty acids such as linoleic acid and linolenic acid, animal and vegetable oils and fats such as soybean oil, corn oil, rapeseed oil, coconut oil, lard, beef tallow, and fish oil, and medium-chain fatty acid triglycerides. Examples include processed oils and fats. These lipids may be used in one type, or two types may be used.
ffl or more may be used in combination, and the blending amount thereof is usually selected in the range of 5 to 35% by weight based on the powder composition.

Vitamins and minerals, which are trace components, are added in nutritionally necessary amounts as appropriate. Also, emulsion stabilizers such as phosphates and citrates, fruit juice, flavors, etc. may be added to the composition of the present invention, if necessary.

The powdered nutritional composition of the present invention can be prepared by adding the above ingredients to water and emulsifying the mixture, and then drying the emulsion by spray drying or the like to form a powder. At this time, cono)citric acid monoglyceride may be used after being dissolved in lipid beforehand, or may be used after being dissolved in water.

Moreover, it is advantageous for the powdered nutritional composition of the present invention to be prepared by preparing a powdered fat or oil in advance and mixing it with other powdered ingredients. That is, using lipids, succinic acid monoglyceride, proteins, and a portion of carbohydrates, these are added to water and emulsified, and then dried by spray drying or the like to obtain powdered fats and oils. In this case, the entire amount of succinic acid monoglyceride contained in the composition of the present invention is used. The powdered oil obtained in this way has good emulsion dispersion stability when added to water and made into a liquid, and maintains a homogeneous emulsion dispersion state even when left at room temperature for several hours or at low temperature for about 2 days. shows. The powdered nutritional composition of the present invention can be obtained by thoroughly mixing this powdered fat and oil with the remaining powdered ingredients.

The powdered nutritional composition of the present invention is prepared by adding it to water or hot water to prepare an emulsion so that the solid content concentration is usually 5 to 40% by weight, preferably 20 to 25% by weight, and then administered orally. It can be easily and quickly supplied to digestive organs such as the stomach and intestines using a tube or the like.
