Description

A food composition containing starch
Technical Field
Starch-containing food composition the present invention relates to a starch-containing food composition having improved properties during gelatinization or thickening of the starch, inhibiting elution of sugars from the starch, and having thermal stability.
Background
Typically, starch is used as a thickening or gelling agent in the production of gelled or pasty food products. Further, it is known that cross-linked starches such as phosphoric acid cross-linking and adipic acid cross-linking improve shape retention and hardness of gels and pastes, as compared to raw starch. However, as the degree of starch crosslinking increases, the shape retention and hardness that can be imparted increases, but there are disadvantages that lead to increased brittleness and starch retrogradation rate. This brittleness and aging cause undesirable phenomena such as texture reduction and water separation.
On the other hand, it is known that the starch thickening function and the gel forming function of starch can be improved by enzymatically treating starch granules at a temperature of about 10 ℃ or more and about 70 ℃ or less (see patent document 1). Further, it is known that by treating starch with the thus obtained enzyme, a gelatinous food product rich in elasticity and having an excellent texture is obtained. The enzyme-treated starch disclosed in patent document 1 is used without chemical modification or in combination with chemical modification or physical treatment to produce a gelatinous food product having excellent hardness, shape-retaining property, elasticity, and the like. Has realized and brought valuable technological advances to the food industry.
However, in the past, in gel or paste foods using starch which has not been subjected to chemical treatment or enzyme treatment, a technique which can improve the properties of starch during gelatinization or thickening has been sufficiently studied. There is currently no situation.
In recent years, in the form of gelatinous foods (noodles, buns, etc.) containing starch, which are distributed in supermarkets, convenience stores, etc., starch is gelatinized in advance and distributed as it is, or can be eaten by simple heating. However, such gel foods have the disadvantage that the foods are combined with each other in the dispensing stage. Therefore, a gel-like flowing food in a state in which starch is α can inhibit desired binding to each other.
In addition, starch-containing pasty foods (e.g., flour pastes) have poor heat stability and have a disadvantage that the external shape cannot be stably maintained upon heating. Therefore, there is a need to develop a technology for providing heat resistance to starch-containing paste foods.
Disclosure of Invention

When a drum dryer or extruder is used, a drying step is generally not required because it is heated at an elevated temperature. Furthermore, the semi-gelatinized or gelatinized starch can be dried by, for example, air drying, spray drying or food drying.

Test example 1: evaluation of physical Properties of the gel
1. Preparation of gel each raw material was suspended in water and stirred, and filled into a Kurehalon casing having a folding width of 45 mm. Next, the temperature was raised from 40 ℃ to 90 ℃ over 1 hour and held at 90 ℃ for 30 minutes. Then, the mixture was left standing in a refrigerator (4 ℃ C.) for 16 hours. Next, the sample was left at room temperature (about 25 ℃) for 4 hours to return to room temperature and used as an analysis sample.
2. Measurement of fracture stress, fracture distance the fracture stress and the fracture length of each gel produced (analytical sample) were determined using a rheetech ltd rheometer (RT-2010J-CW). As the measurement conditions of the rheometer, a fracture test was performed as a test item. The height of the sample was 25mm, and the moving speed (breaking speed) of the sample was measured at 6cm/min using an adapter having a viscosity ball Φ 5 (diameter 5mm, area 19.635mm 2). Further, the ratio (%) of the breaking stress of each gel when the breaking stress of each gel produced using starch alone was taken as 100% was calculated as the rate of change in breaking stress. Then, the product value of the breaking stress and the breaking distance was defined as the gel strength (g · cm), and the gel strength ratio (%) at which the gel strength of each gel was 100% was calculated as the gel strength change rate.
3. The result obtained is that the breaking stress in the gel containing cellulose and/or xanthan gum and starch is lower than in the starch alone. On the other hand, in the gel containing the complex cellulose and the starch, the breaking stress and the gel strength are improved as compared with the starch alone. From the above results, it can be seen that the complex cellulose can impart stiffness and elasticity to the starch-containing gel.
