    断奶前的营养和健康会影响小牛未来的生育能力,产卵年龄,生产,和载波长度。小牛极易感染新生儿小牛腹泻(NCD),这可能是致命的。NCD是由于低血容量和酸中毒,这可能涉及厌食症和共济失调。“一个健康”原则要求大幅减少抗菌药物的使用。一种方法是改善动物健康并减少由于生物活性化合物而具有有益效果的抗生素和功能性成分的使用。可以考虑几种功能成分和添加剂,and,特别是对于这项研究,考虑了夜蛾。本研究旨在评估结球芽孢杆菌作为一种功能性成分在新生小牛代乳品中的作用。十二只断奶前的荷斯坦弗里斯小牛,在相同的环境条件下安置在十二个单独的围栏中,分为两组,每组六只动物:对照组(CTRL,n=6)用牛奶替代品喂养,和一个治疗组,在他们的饮食中接受富含10克结节状芽孢杆菌的牛奶(TRT,n=6)为42天。每天进行粪便评分(3-0量表),以监测两组腹泻的发生率。每周评估体重,每两周收集一次粪便进行微生物评估,使用选择性培养基进行平板计数,乳酸,和大肠杆菌。为了验证乳酸菌的存在,双歧杆菌,和大肠杆菌,使用实时qPCR。在审判开始和结束时,采集血样进行血清代谢物分析.两组的增长表现均无差异,但观察到中度腹泻的发生率存在显着差异(p值<0.0113),其中TRT组在42天期间的病例发生率较低。血清分析显示白蛋白含量较高,钙,磷,与CTRL相比,TRT组的总胆固醇(p值<0.05)。总之,在小牛的饮食中实施结球芽孢杆菌可以导致更好的动物福利,并可能减少抗生素的使用。
    Nutrition and health during pre-weaning affect the calves\' future fertility, calving age, production, and carrier length. Calves are highly susceptible to neonatal calf diarrhea (NCD), which can be fatal. NCD is due to hypovolemia and acidosis, which may involve anorexia and ataxia. The One Health principle calls for a drastic reduction in antimicrobial use. One approach is to improve animal health and reduce the use of antibiotics and functional ingredients that have beneficial effects due to bioactive compounds. Several functional ingredients and additives can be considered, and, in particular for this study, Ascophyllum nodosum was considered. The present study aimed to evaluate the role of A. nodosum as a functional ingredient implemented into the milk replacer in neonatal calves. Twelve pre-weaned Holstein Frisian calves, housed in twelve individual pens in the same environmental conditions, were divided into two groups of six animals: a control group (CTRL, n = 6) fed with a milk replacer, and a treatment group receiving milk enriched with 10 g of A. nodosum in their diet (TRT, n = 6) for 42 days. The fecal score was evaluated daily (3-0 scale) to monitor the incidence of diarrhea in the two groups. The body weight was evaluated weekly, and every two weeks feces were collected for microbiological evaluation using a selective medium for plate counting of total, lactic acid, and coliform bacteria. To verify the presence of Lactobacillus, Bifidobacterium, and Escherichia coli, real-time qPCR was used. At the beginning and at the end of the trial, blood samples were obtained for serum metabolite analysis. The growth performance did not differ in either of the two groups, but significant differences were observed in the incidence of moderate diarrhea (p-value < 0.0113), where the TRT group showed a lower incidence of cases during the 42-day period. Serum analysis highlighted higher contents of albumin, calcium, phosphorus, and total cholesterol in the TRT group compared to CTRL (p-value < 0.05). In conclusion, implementation of A. nodosum in the diet of calves can lead to better animal welfare and may reduce the use of antibiotics.

    近几十年来,消费者对健康生活方式和多样化饮食的承诺经历了快速增长,导致对更好的食品质量和品种的需求增加。食品工业选择了创新和寻找新的食物来源,这些趋势导致需要制定欧洲监管框架。新食品符合法规(EU)2015/2283(原法规(EC)第258/97号),这一概念包括在1997年5月15日之前未在欧盟用于人类消费的重要措施中使用的所有食品,并且包括在任何已建立的食品类别中。目前,有26种提取物被授权为新型食品或配料,是最多的群体之一。这些提取物是浓缩的营养来源,其中23种可用于食品补充剂。考虑到它们的异质性组成和进行的感知风险评估,有时,授权仅限于某些人口群体。目前的工作是对富含营养素的提取物的全面审查,这些提取物被授权作为欧盟食品补充剂中的新成分。根据它们的来源提出了分类,导致四个主要组:植物提取物,动物,藻类,和真菌起源。还介绍了每种提取物的描述以及对潜在使用限制和健康益处的评估。
    Consumers\' commitment to healthy lifestyles and a varied diet has experienced rapid growth in recent decades, causing an increase in the demand of better food quality and variety. The food industry has opted for innovation and the search for new sources of food, and these trends led to the need to develop a European regulatory framework. Novel foods are under Regulation (EU) 2015/2283 (formerly Regulation (EC) No 258/97), and this concept includes all food not used in an important measure for human consumption in the EU before 15 May 1997, and which is included in any of the food categories established. Currently, there are 26 extracts authorized as novel foods or ingredients, being one of the most numerous groups. These extracts are concentrated sources of nutrients, and 23 of them can be used in food supplements. Given their heterogeneous composition and the perceptive risk assessments performed, sometimes, the authorizations are limited to certain population groups. The present work is a comprehensive review of the extracts rich in nutrients authorized as novel ingredients to be used in food supplements within the EU. A classification is proposed according to their source of origin, resulting in four main groups: extracts of plant, animal, algae, and fungal origins. A description of each extract as well as the evaluation of the potential use restriction and health benefits are also addressed.

    3D printing is a technology capable of presenting creative, unique and intricate items in an attractive format, with specific compositions. However, novel ingredients must be developed to satisfy this new technological requirement. This work proposes dry heating treatment (DHT), a simple physical technique, as a method for modifying cassava starch, with particular focus on its use for 3D printing. DHT processing was conducted at 130 °C for 2 and 4 h (named DHT_2h and DHT_4h, respectively). Different gelatinization conditions (65, 75, 85, and 95 °C) were applied, and the hydrogels were evaluated considering different storage periods (1 and 7 days). Cassava starch properties were evaluated, focusing on the application of its hydrogels to 3D printing. The increase of DHT time produced a starch with higher carbonyl content and bigger granule size. It also reduced the water absorption index, increased the water solubility index, affected granule crystallinity and reduced molecular size. The longest storage period increased gel firmness. Increasing the temperature used in the gelatinization process reduced the gel strength of the native and DHT_2h. DHT_4h showed the lowest peak apparent viscosity and provided the strongest gels for all the evaluated conditions. Gels produced with DHT starches exhibited better printability than the native starch, mainly for the DHT_4h. This treatment was chosen to print 3D stars, and displayed better resolution than the native gels. Therefore, by using DHT, it was possible to obtain hydrogels with enhanced pasting properties, gel texture, and printability, thereby expanding the potential of applying cassava starch to 3D printing.

    The feasibility of producing durum wheat pasta enriched with a lipophilic phytocomplex, extracted using supercritical carbon dioxide (SC-CO2), from ripe pumpkin, as free oil or as ready-to-mix oil/α-cyclodextrins (α-CDs) powder, was explored. Four types of pasta were prepared: (i) control spaghetti (S-CTRL); (ii) spaghetti supplemented with α-CDs (S-α-CD); (iii) spaghetti supplemented with pumpkin oil (S-Oil) and (iv) spaghetti supplemented with the pumpkin oil/α-CD powder (S-Oil/α-CD). The chemical, antioxidant, textural and sensory attributes of the different pasta were evaluated and compared. S-Oil and S-Oil/α-CD spaghetti were significantly enriched with phytosterols, squalene, carotenoids, tocochromanols and unsaturated fatty acids. Spaghetti containing α-CDs were slightly improved in terms of fiber content. Oil chlatration increased the stability of some bioactives during pasta production and ameliorated poor textural and sensory characteristics of the cooked spaghetti compared with S-Oil sample. S-Oil/α-CD spaghetti might be accepted by customers, if the potential health benefits were also explained.
