摘要
以山楂和乳粉为主要原料,经降酸、混合、造粒、干燥、整粒、压片等工序制备山楂风味奶片。以感官评分、质量差异、硬度和脆碎度作为评价指标,在单因素试验的基础上进行BoxBehnken响应面试验,通过优化山楂风味奶片的配方中山楂果粉、微晶纤维素和木糖醇的用量,得到山楂风味奶片的最佳配方为:全脂甜乳粉100 g、山楂果粉42.87 g、微晶纤维素19.71 g、木糖醇14.79 g、硬脂酸镁0.5%。用此配方制得的山楂风味奶片表面光滑,兼有山楂和牛乳的风味。与市售奶片相比,山楂风味奶片含有较高的粗蛋白和较低的粗脂肪,还含有丰富的粗纤维素和黄酮类化合物,营养成分更加丰富,具有较高的抗氧化活性。最佳制备工艺下,得到的山楂风味奶片的口感酸甜,兼有山楂和乳粉的双重营养和保健作用,符合健康饮食的理念。
Using hawthorn and milk powder as the main ingredients,the hawthorn flavored milk tablets was prepared through processes such as deacidification,mixing,granulating,drying,granulating and tableting.With the score of sensory,tablet weight variation,hardness and brittleness as evaluation indicators,the Box-Behnken response surface test was carried out based on single factor experiment to optimize the amount of hawthorn powder,microcrystalline cellulose and xylitol in the formula of hawthorn flavored milk tablets.The best formula of hawthorn flavored milk tablets was:full cream milk powder 100 g,hawthorn powder 42.87 g,microcrystalline cellulose 19.71 g,xylitol 14.79 g and magnesium stearate 0.5%.The hawthorn flavored milk tablets,which prepared by this formula,had a smooth surface and had the flavors of hawthorn and milk.Compared with commercially available milk tablets,the hawthorn milk tablets contained higher crude protein and lower crude fat.And it was rich in crude cellulose and flavonoids,with richer nutrients and higher antioxidant activity.The hawthorn flavored milk tablets prepared with the best preparation technology had sweet and sour taste and had the dual nutritional and health care functions of hawthorn and milk powder,which conforms to the concept of healthy diet.
