“冷冻酸奶”及其制造 总被引:3,自引:0,他引:3
前言冷冻酸奶(Frozenyoghurt)是欧美各国十分流行的冷冻饮品,它将酸奶的香味与冰淇淋的冰凉感觉有机地结合,物理形态上类似冰淇淋、带有冰淇淋独特滋味、质地,是有益于健康的一种冷冻甜食。在酸奶消费的带动下,冷冻酸奶的消费亦呈上升趋势。“冷冻酸奶”与冰淇然中的新品──—酸奶冰淇淋都要通过盛冻机打膨胀率,外观形态、保存销售条件相似,许多人将两者混为一谈。严格地讲,无论从配方还是工艺,都有明显的不同。在酸奶冰淇淋中,突出酸奶味道,酸奶作为一种配料加入,主要是为了呈现风味,可以说适当调节混合料的酸度再加入适当… 相似文献

通过添加不同改性淀粉制备冷冻酸乳冰淇淋,分别研究不同改性淀粉及添加量在冷冻处理前对酸乳样品的硬度和黏度的影响,以及在冷冻处理后对冷冻酸乳冰淇淋样品冻融稳定性和感官品质的影响。结果显示,随着改性淀粉添加量在0~1.2 g/100 g范围增加,酸乳样品的硬度和黏度均呈现不同程度的增加,并且全部冷冻酸乳冰淇淋样品的乳析指数均呈现不同程度的下降,其中添加辛烯基琥珀酸酐(OSA)酯化淀粉微粒的样品,其硬度和黏度的增幅最大,分别为67.64%和93.43%,并且表现出最佳的冻融稳定性,其乳析指数下降幅度最大,为52.28%。当OSA酯化淀粉微粒添加量为0.8 g/100 g时,其感官品评综合得分最高,为90.54分,表明此种改性淀粉在提高冷冻酸乳冰淇淋品质上具有良好的应用效果。 相似文献

在冰激凌中添加益生菌,既可以丰富冰激凌产品的种类,制作兼顾健康与美味的功能性产品,又为益生菌合理利用找到新的载体。益生菌冰激凌可以改善人体肠道吸收营养物质的情况,但是益生菌在冰激凌搅打过程和冷冻保存条件下容易受到机械损伤从而降低其益生活力。为此,通过在冰激凌配方中添加益生元,蛋白质等固形物以改善菌种的生存条件,从而保护益生菌的益生作用。配方固形物种类繁多,对益生菌抗冷冻胁迫的方式亦有不同,本文从酸乳冰激凌的添加配方出发,对各类对益生菌在冷冻胁迫条件下起保护作用的固形物的理化特性和作用机理进行综述,为益生菌冷冻胁迫保护和益生菌冰激凌的生产提供新的思路。 相似文献

In the present work, fat reduction of Greek strained yoghurt ice cream (YIC) was carried out in three proportional milkfat levels i.e. 30, 50 and 70% using three types of oligosaccharides namely long-chain inulin, oligofructose and maltodextrin 12 DE. Greek strained yoghurt was blended with ice cream mixes in ratios of 1:3 and 1:1. The physico-chemical, textural and thermal characteristics of the YIC mixes and their obtained frozen end products were determined. The sensory modalities (olfactory, gustatory, tactile and oro-tactile) of the YIC were monitored following 2 and 16 weeks of quiescent frozen storage at ?25 °C. Milkfat reduction impaired significantly (p?<?0.05) the perceived creaminess and mouthcoating sensation stimuli, whist it intensified the oral tissue friction associated sense stimuli such as astringency, wateriness and coarseness. Long-chain inulin- and maltodextrin-based samples received the highest scores for creaminess, mouthcoating, gumminess, hardness and iciness. The increase of the yoghurt to ice cream mix ratio escalated the friction/recrystallization-associated sensations e.g. astringency, sourness, coarseness and wateriness. Notwithstanding yoghurt supplementation reinforced the pseudoplasticity and macroviscosity of the ice cream mixes, it suppressed their aeration capacity leading to heavy-bodied ice creams. However, no significant effects of yoghurt supplementation level on the colligative and meltdown rate of the YIC formulations were identified. Partial least squares coupled discriminant analysis (PLS-DA) revealed that fat reformulation of YICs using oligosaccharides results in a substantially diversified sensory profile. Generally, a 50% fat reduction of YICs using long-chain oligosaccharides appears to be a technologically tangible solution. 相似文献

Commercially available antibodies were used for the detection and quantitation of ovalbumin in ice cream and cheese. Electrophoretic separation of protein components, followed by blotting and immunochemical recognition of ovalbumin allowed the detection of the addition of 50 g kg-1 egg white to processed cheese and allowed detection of egg in ice cream. For quantitative purposes a competitive ELISA method was set up. Calibration curves for ovalbumin in various products were obtained. A marked matrix effect was evident in ice cream, cheese and yoghurt. Different types of cheese gave nearly identical matrix effects. Analytical application of the method should therefore be possible, at least within a given class of products. A study on the influence of thermal treatments on the ELISA response showed that melting of cheese at various temperatures modifies only slightly the ELISA response for ovalbumin. 相似文献
