胡萝卜-甜橙复合果汁乳饮料的工艺设计.doc

长春工业大学本科毕业论文PAGE-34-摘要在各种饮料中，乳饮料独树一帜，它在解渴的同时，还添加了牛乳，是一种营养丰富，风味独特的新型饮料。制作乳饮料的胡萝卜营养丰富，有治疗夜盲症、保护呼吸道和促进儿童生长等功能。此外还含较多的HYPERLINK"http://baike.baidu.com/view/39101.htm"\t"_blank"钙、HYPERLINK"http://baike.baidu.com/view/39167.htm"\t"_blank"磷、HYPERLINK"http://baike.baidu.com/view/4649.htm"\t"_blank"铁等矿物质。科学表明，经常食用胡萝卜不仅益肝明目，利膈宽肠，而且可健脾除疳，增强免疫功能。胡萝卜降糖降脂，是糖尿病人、高血压、冠心病患者的食疗佳品。甜橙含有大量维生素C，可以达到美白和抗感冒的作用，长期食用还有抗癌功效。为充分利用胡萝卜和甜橙，开发研究胡萝卜-甜橙复合乳饮料。胡萝卜和橙子榨汁后，调制成复合果汁，再与鲜奶混匀制成复合奶，加入白砂糖和CMC-Na，经均质、杀菌和灌装等工序得成品。同时本实验对胡萝卜-甜橙复合乳饮料的最佳配方进行了探索，经多次调配后，得出最佳配方：胡萝卜汁与橙汁的比例为2:3，复合果汁加入量为45％，鲜奶加入量为45％,加糖量为10％，稳定剂CMC-Na用量为0.3％。成品呈浅粉红色，酸甜可口，粘度适中，PH值为3.8～4.1，糖度为l0％，蛋白质≥0.75％，脂肪≥0.85％，总固形物≥l1％。关键词：胡萝卜汁；橙汁；复合乳饮料。TheDevelopmentofCompoundMilkBeveragewithCarrotandSweetOrangeAbstractInavarietyofbeverages,milkbeverageisunique.Notonlycanitrelievethirst,butitisalsoaddedtomilk,whichhasrichnutritionanduniqueflavorofthenewdrink.Thenut-ritionofthecarrotisrich,itcantreatnightblindness,protectrespiratorytractandpromotechildren'sgrowth,andotherfunctions.Inaddition,itwithmorecalcium,phosphorus,ironandotherminerals.Scienceshowsthateatingcarrotfrequentlycannotonlyprofitliveandclearvision,favordiaphragmandwideintestine,butalsomaybegoodforthespleenandtoeliminatemalnutrition,enhanceimmunologicfunction.Thecarrotfallsthesugarandfat,whichisthediabeticpatient,hypertension,coronarydiseasepatient'snutritionalandhighqualityfoods.SweetorangecontainsalotofvitaminC,mayachievethewhiteningandtheanti-cold'sfunction,long-termediblealsohastheanticancertreatmenteffect.Inordertomakefulluseofcarrotandorange,thecompoundmilkbeveragewithcarrotandorangeisdeveloped.Afterbeingsqueezed，carrotjuiceandorangejuicearemixedwithfreshmilk，thenaddedwithgranulatedsugarandCMC-Na，andthengethomogenized，sterilizedandcanned，thefinalproductisproduced．Itsoptimalingredientsareasthefollowings：theratioofcarrotjuicetoorangejuiceis2:3，theamountofcompoundjuiceis45％，theamountoffreshmilkis45％，theamountofsugaris10％，theamountofstabilizationagentCMC-Nais0.3％Withalightpin
