摘　　要：研究以白桃、白桃清汁、青柠原浆、奇亚籽和果葡糖浆为原料,不添加食品添加剂,采用合理的制作工艺制成一种应用于酸奶的新型复合果酱。通过单因素试验、正交试验和工艺验证试验,确定白桃奇亚籽果酱的最佳配方工艺:以白桃丁+白桃汁+果葡糖浆质量100%计,白桃丁添加量50%、白桃清汁添加量20%、果葡糖浆添加量30%、奇亚籽添加量4%、青柠原浆添加量5.5%,真空度0.05 MPa、加热温度85℃、熬制时间10 min。在此最优配方工艺下制作的白桃奇亚籽果酱,产品pH 3.6,黏稠度为8.0~9.0 cm/30 s,可溶性固形物含量为34.7 Brix;菌落总数<10 CFU/g,大肠菌群、霉菌和致病菌均未检出。果酱添加到原味酸奶中,酸奶口味酸甜可口、细腻爽滑,具有浓郁的白桃独特风味和奇亚籽的清香,气味协调;白桃丁色泽鲜艳、口感硬脆;奇亚籽比例恰当、分布均匀,咀嚼感丰富。A new type of compound jam used for yoghurt was made by white peach,white peach clear juice,lime puree,chia seed and glucose-fructose syrup as the raw materials,with non-additives,though appropriate processing technology.The optimal formula of white peach and chia seed jam was determined by single-factor experiment,orthogonal experiment and verification test.Following the weight of top three raw materials 100%,the additive amount of each raw materials was 50%white peach,20%white peach clear juice,30%glucose-fructose syrup,4%chia seed and 5.5%lime puree,and heating time was 20 minutes at 85℃in vacuum degree of 0.05 MPa.The pH of white peach and chia seed jam under such conditions was 3.6,the viscosity was 8.0-9.0 cm/30 s,and the content of soluble solid was 34.7 Brix.The total number of bacterial colonies were less than 10 CFU/g,and coliform bacteria,fungi and pathogen were not detected.When adding the jam of white peach and chia seed,the yogurt was moderate sweetness and sourness,delicate and smooth,fullness white peach and chia seed flavor.The white peach cubes of jam were naturally bright-colored and crisp texture,and the chia seeds were well-proportioned and chewy.
