The white sapote tree is cultivated in Egypt on a limited scale owing to its dietary fruits. For its medical and functional characteristics, different levels of dried white sapote fruit (DWSF) were utilized in the manufacturing of probiotic goat yoghurt drinks as a milk fat replacer, as well as yoghurt cultures of La-5 and Bb-11. The implications of DWSF on the rheological properties (apparent viscosity, flow behavior index, plastic viscosity, consistency coefficient, and yield stress), gross composition, color, sensory, bioactive, and microbiological properties of yoghurt drinks were studied throughout 15 days of storage at 4 °C. The addition of DWSF enhanced the bioactive compounds, water-holding capacity, sensory properties, rheological parameters, color, and bacterial growth. Furthermore, mold, yeast, and coliform were not found in any of the samples until the storage time was over. The total number of viable cells in probiotic treatments was kept at a functional level (>10 CFU/mL) for 15 days. The aggregate results showed that it is possible to generate high-quality bio-yoghurt drinks from goat milk with a delightful flavor, appearance, body & texture, and color by substituting goat milk fat with up to 75 % dried white sapote fruit. The successful creation of high-quality bio-yoghurt drinks from goat milk, enriched with DWSF, not only presents a delightful flavor, and pleasing texture but also signifies a health-conscious innovation. This research paves the way for further investigations into the integration of novel fruit-based ingredients in dairy products, offering new dimensions in the functional foods field.
由于其食用果实,埃及对人心果进行了小规模种植。鉴于其医学和功能特性,不同含量的干燥人心果果实(DWSF)被用于生产益生菌山羊酸奶饮料,以替代乳脂肪,同时还用于生产La - 5和Bb - 11酸奶发酵剂。在4℃下储存15天的过程中,研究了DWSF对酸奶饮料的流变学特性(表观粘度、流动行为指数、塑性粘度、稠度系数和屈服应力)、总体成分、颜色、感官特性、生物活性和微生物特性的影响。添加DWSF提高了生物活性化合物、持水能力、感官特性、流变学参数、颜色和细菌生长。此外,在储存期结束前,任何样品中均未发现霉菌、酵母菌和大肠菌群。益生菌处理中的活细胞总数在15天内保持在功能水平(>10 CFU/mL)。总体结果表明,用高达75%的干燥人心果果实替代山羊乳脂肪,有可能从山羊奶中生产出具有宜人风味、外观、质地和颜色的高品质生物酸奶饮料。成功地用富含DWSF的山羊奶制作出高品质生物酸奶饮料,不仅具有宜人的风味和令人愉悦的质地,还标志着一种注重健康的创新。这项研究为进一步研究将新型水果基成分融入乳制品铺平了道路,为功能性食品领域提供了新的维度。
