Date fruit based products are gaining popularity among the consumers in almost all date growing countries due to its added nutritional value. Therefore, novel products were developed by combining two types of foods i.e., soft ripened cheeses and date fruit syrups or date powder. This study is the first to report the surface mold-ripened cheese production with date syrup and date powder. Model cheeses were prepared from pasteurized milk inoculated with Streptococcus thermophilus, Penicillium camemberti and Geotrichum candidum. Date syrup-1, date syrup-2, date powder or the date mixture were added at the stage of curdling. Based on the kinetic growth of the microbial groups in all the treatments, there was no change in the growth of these in various date palm product. On the contrary It may be said that addition of the date fruit product supports their growth. After 35 days, the amounts of total poly phenols were 128.3 ± 1.01, 81.8 ± 1.11, 33.5 ± 2.19, 156.23 ± 1.27 mg GAE/100 g in the cheeses support with date syrup-1, date syrup-2, date powder or the date mixture, respectively. Antioxidant activity of date fruits ranged from 80.13 IC50 (date syrup-2) to 82.23 IC50 (date syrup-1). Based on the chemical characteristics and sensory analysis, the study results showed the potential for innovative application of date products for developing new functional dairy products as an ideal medium for the delivery of biological active compounds with beneficial health effects over.
由于其增加的营养价值,枣类水果制品在几乎所有枣类种植国家的消费者中越来越受欢迎。因此,通过将两种类型的食物即软熟奶酪和枣类水果糖浆或枣粉结合,开发出了新颖的产品。本研究首次报道了用枣糖浆和枣粉生产表面霉菌成熟奶酪。模型奶酪由接种嗜热链球菌、卡门培尔青霉和白地霉的巴氏杀菌牛奶制成。在凝乳阶段添加枣糖浆-1、枣糖浆-2、枣粉或枣类混合物。基于所有处理中微生物群体的动力学生长,在各种枣椰产品中这些微生物的生长没有变化。相反,可以说添加枣类水果产品支持它们的生长。35天后,在分别添加枣糖浆-1、枣糖浆-2、枣粉或枣类混合物的奶酪中,总多酚含量分别为128.3±1.01、81.8±1.11、33.5±2.19、156.23±1.27mg GAE/100g。枣类水果的抗氧化活性范围为80.13 IC50(枣糖浆-2)至82.23 IC50(枣糖浆-1)。基于化学特性和感官分析,研究结果表明枣类产品在开发新型功能性乳制品方面具有创新应用潜力,可以作为传递具有有益健康作用的生物活性化合物的理想介质。
