China is the world's largest rice growing and consuming country.The requirements of people on the rice color,aroma,taste and taste and so on also with China's rapid development of economic and people's living standards continue to improve is also getting higher and higher,rice is not only to eliminate hunger,but to meet the comprehensive needs more nutrition and taste of.The development of deep processing of agricultural products is the core content of the strategic adjustment of agricultural structure,agricultural economic development support,to broaden the market demand of agricultural products,improve agricultural efficiency,increase the income of the farmers is important.From the fact of the character of the war and the army,future war requires protection food must be high scientific and technological content of the food,both civilian food in general,but also has its particularity,to the troops in extreme environments,such as nuclear pollution,biological pollution,extreme high pressure and low temperature and extreme temperature and pressure conditions,still can meet the needs of modern warfare.From foreign armies advanced field rations experience,combined with the comprehensive consideration of national conditions of our country,full nutrition,high energy composite convenient protection rice may is the development trend of military food.In this paper,the northeast rice and beef powder,carrot powder as the main raw material,add salt and monoglyceride are fully mixed,using a twin-screw extruder re made in the shape of a grain of rice,the physicochemical characteristics of the system and analyze the products designed to explore the impact of full nutrition,high energy composite square and protection of rice taste taste of deep-seated reasons,looking for full nutrition high energy composite convenient protection of rice the best ratio of raw materials,full nutrition high energy composite convenient protection of rice production technology twin-screw extrusion parameters and complex water exploration,main research results such as:(1)Study on the high energy compound and convenient military rice raw material proportioning.In this experiment,the taste of military rice was used as a reference index,and the extrusion parameters of the double screw extruder were fixed.And through the orthogonal experiment results show that the composite convenient protection rice beef content is 15%,carrot powder adding amount is 10%,edible salt addition amount is 1.2%,monoglyceride adding amount was 0.8%,the best taste,the carrots and salt on composite convenient protection rice taste effect maximum.(2)Study on the taste and re-water time of the whole nutrient-high-energy compound and convenient military rice with twin-screw extrusion.Through the single factor experiment,compound protection of rice taste and rehydration time as index,fixed ratio of material parameters and drying conditions were investigated.Composite protection rice extrusion parameters effect on the taste and rehydration.On the basis of single factors determined the range,composite protection rice taste and rehydration time as the index design orthogonal experimental program,determine the combined protection of rice extrusion parameters of the optimal scheme: double screw extrusion machine temperature zone temperature is 65 DEG C,2,3 temperature zones temperature of 115 DEG C,liquid feed water is 20%,double screw speed 180 Rpm.At this time of the comprehensive score of the highest and the barrel 2 and 3 temperature zone temperature and barrel temperature zone temperature on the protection of rice taste effect maximum.The extrusion parameters of the optimal scheme are combined to facilitate the micro structure analysis of the military rice and the rice and raw materials,the internal structure of the compound military rice is more loose,and the complex water performance is better.Through scanning electron microscope analysis,the raw material rice surface starch granule basically intact without damage.Raw rice starch granules were mostly irregular polyhedron structure,edges and corners.After extrusion cooking processing,rice starch particles melt,not observed the complete structure of the starch granules.The commercially available convenient internal structure Steamed Rice rice closely,a small amount of space,forming a relatively smooth surface.Composite extrusion m internal rubbery plate structure obviously.This structure helps to delay the aggregation of starch molecules,inhibiting starch retrogradation.(3)Composite convenient protection of rice by squeezing the gelatinization,with a certain degree of gelatinization,therefore has the diversity of consumption,in order to meet the requirements of the instant,the hot water immersion rehydration edible.Through single factor experiment,the effect of the compound water meter water ratio,the complex water time and the water temperature on the taste of the compound convenient military rice were investigated.Through the orthogonal experiment results show that when the complex water meters of water ratio of 1:0.8,rehydration time was 13 min,the rehydration temperature is 70 DEG C for the protection of rice complex water condition is verified by the experiment,to obtain complex water samples,test the products taste score the highest.If the composite rice absorbs water less than 30%,then in the process of re water,because the water is too little,rice is not enough water,it will directly affect the quality of rice.Compound water time is too long or complex water temperature is too high,the rice in the soluble nutrients will lose too much,the white degree of rice will also reduce the rate of burst waist is also increased,seriously affect the quality of rice.Complex water time is too short,easy to make the composite protection rice cooked rice,time is too long,the amount of water too much,the starch gelatinization excessive,the rice is too soft,no elasticity.Through of raw rice,city sale of convenient rice composite protection rice basic physicochemical indexes determination and analysis,can understand the amount of loss of the essential nutrients for composite protection of rice in the process of production is not high,and add the beef and carrot sake,making the main nutritional components of composite protection of rice more high,especially protein content,fat content and total sugar content increased significantly.
