摘要： Black cumin seed oil has high nutritional value. However, due to its peppery taste, strong odor, and rapid oxidative deterioration, its application in food formulations has been limited. Encapsulation techniques with hydrocolloids combined with other nutritive wall materials may overcome these problems and provide more health benefits for consumers. For these reasons, cold-pressed black cumin seed oil was microencapsulated by spray drying in four different microcapsule models, including gum arabic alone (GA) and in combination at a 50:50 ratio with maltodextrin (GM), inulin (GI), or whey protein (GW). The microencapsulation efficiency of GA presented the highest yield of up to 88%. Replacing 50% of the gum arabic with whey protein (GW) reduced the microencapsulation efficiency from 88 to 75% while GI and GM were 86.12 and 83.51, respectively. The wettability and solubility of the microencapsulated powders prepared (GI, GM, and GW) were superior to those of the microcapsules prepared by gum arabic alone. Under SEM, the GA and GM powders collapsed at the surface, while the GI and GW powders were spherical and smooth. The highest thymoquinone content was found in the GI powder. There were no differences (P.0.05) in the thymoquinone content observed among all powders.

关键词： 课程思政   物理化学   高校教学  

摘要： 课程思政是课程教学之魂。本文从教学目标、教学内容、学习理论和思政教育4个维度给出了课程思政本质内涵的认知,结合新时代高等教育课程教学新要求,给出了在符合情感态度品德教育理论的前提下实施课程思政的教学方法。以《物理化学》课程为例,根据其课程思政目标内容,进行了课程思政点、线、面、体的整体内容设计和教学策略设计;根据“格物-致知-明德”教育理念,基于“CEPRAE”六步基本教学法,设计并实施了课程思政生成性课堂教学模式,教学实践表明,“格物-致知-明德”的课程教学在更新教学观念、紧跟时代需求、创新教学内容、应用信息技术、立足课程思政和开展对外交流等方面均表现了很好的成效。

关键词： 药学专业   物理化学   课程思政   设计与探索  

摘要： 对在药学专业物理化学中融入课程思政元素进行了设计与探索。首先,改革后的教学目标除知识目标外,增加了5个素质目标;其次,围绕素质目标对教学内容进行设计,融入五大思政要素,在专业课中引入“狭义”思政元素,即思想品德教育;再次,通过教学环节的设计,采用多种教学模式,培养学生的综合素质,引入“广义”思政元素;最后,在教学效果评价中增大素质目标考核的比例,促进素质目标的达成。通过以上途径,在实际教学中取得了较好的效果,一定程度完成了专业课的育人职责。

关键词： Arabinoxylan hydrolysate   Soy protein isolate   Maillard conjugates   beta-Carotene emulsions   Physicochemical stability  

摘要： The physicochemical stability of beta-carotene emulsions and the bioaccessibility of beta-carotene stabilized by arabinoxylan hydrolysate (AX(H))-soy protein isolate (SPI) conjugates (formed by dry heating) was evaluated. p-Carotene emulsions were prepared using SPI, AX(H)/SPI mixtures and AX(H)-SPI conjugates separately. Results of mean droplet size and zeta potential indicated that AX(H)-SPI conjugates-stabilized emulsions are less sensitive to environmental stress, and exhibit better stability during long time storage and simulated gastrointestinal digestion, as compared with emulsions stabilized with AX(H)/SPI mixtures or SPI alone. In addition, emulsions stabilized by AX(H)-SPI conjugates exhibited higher chemical stability and bioaccessibility of beta-carotene. These results suggested that AX(H)-SPI conjugates-stabilized emulsions developed in this study have potential applications as protectors and carriers of liposoluble active ingredients.

关键词： Bioative   Light cream cheese spread of goat milk   Brazilian cheese   Fat reduction   &ldquo   Requeijao cremoso&rdquo  

摘要： This study aimed to develop a light cream cheese spread of goat milk enriched with phytosterols, and to evaluate the physicochemical, rheological, and microbiological parameters. Three formulations of light cream cheese spread were developed: without phytosterols (LGC), with 3 g of phytosterols/100 g (LGC3) and with 6 g of phytosterols/100 g (LGC6). Traditional cream cheese spread (TGC) was used as a control. The light formulations showed high protein content (15.88 g/100 g) and reduced fat content (12.00 g/100 g), which contributed to the caloric reduction of the products when compared to (TGC). The apparent viscosity at 10 s-1 (201.8-224.8 Pa s) and adhesiveness (12.80-13.20 mJ) parameters in LGC3 and LGC6 differed significantly from TGC product. All spreads were in accordance with the microbiological standards recommended by Brazilian legislation during the 90 days of monitoring. The results indicate that the light cream cheese spread from goat milk can be used as matrix for introducing phytosterols. Therefore, the light cream cheese spread from goat milk with the addition of 6 g of phytosterols/100 g presented characteristics of a functional food with potential for LDL cholesterol reduction.
