Starch energy gum is an emerging movement of food, it's a huge potential for development, the broad consumer market, but domestic produce less, different product formulations and foreign markets, the price is more expensive. The paper in accordance with the special requirements of the sports food - easy to carry, easy to swallow, easy to digest, quick energy supply, long shelf life, such as corn starch digested for energy as an energy gum substances amylase hydrolyzate should have the properties, and in accordance with the characteristics of the energy gum its properties, structural analysis, determine the optimum energy plastic raw materials and formulations to prepare a good performance of the carbohydrate energy gum. First, corn starch, potato starch, waxy maize starch as raw material, starch hydrolysis reaction process parameters to prepare a series of enzymatic degradation products of starch and its analysis and comparison, according to the characteristics of the energy gum DE values, transparency, viscosity of the indicators were investigated, initially identified the Preparation of starch energy gum with corn starch as raw starch. Second, using scanning electron microscopy, high-performance liquid chromatography, gel chromatography, rheometer starch hydrolysis product of the nature of structural analysis. The results show that: the as the the starch hydrolysates DE value increases, the viscosity of the product becomes low, the transparency becomes high, difficult to retrogradation, the stability becomes good. The surface grain structure, the sugar composition, the size of the molecular weight and molecular weight distribution, the difference is caused by the difference of the sample properties. The larger the sample molecular weight, the higher the content of macromolecules, more particulate occurring molecules, molecular weight distribution is more uneven, the worse the stability of the nature of the sample, water-soluble is worse the higher the viscosity, the more prone to retrogradation; MW Etsu low, the higher the content of small molecules, the molecular weight distribution is more uniform, more stable the sample nature. Thus obtained as the main raw material of the energy gum was prepared DE value should be between 10-20, a concentration of 60% or less as well. Determine the best recipe starch energy gum: raw materials made products F, that is the total mass of the products per bag of 45g, containing starchy 25g, Sodium 50mg, Potassium 30mg every 30-45 minutes of exercise consumption of a bag. Add 22.5mg sodium citrate and 0.5mL concentration of 1% natural flavors and active role in the performance of the products, and will not add it affects the speed of energy gum provides energy. Established model of carbohydrates in vitro digestion experiments using trypsin hydrolysis of carbohydrates, reducing sugar release rate to examine the energy gum digestion rate that the energy release rate. Experimental results show that the energy gum can provide energy within 30min. Compared with native starch products are much higher than ordinary starch digestion rate and extent of complete digestion. Animal experiments showed that the group of mice fed with the energy gum mean exhaustive swimming time and the time of death than the control group increased 9.1% and 10.7%, respectively, indicating that energy intake before exercise glue for mouse motion required ability to contribute to the improvement of exercise capacity, the energy developed in this subject starch glue in quickly for good performance and improve athletic ability, to achieve the desired effect.
