    本研究旨在研究谷物和发芽的假粒整合到定型型酸奶模拟物中,产生了一种新颖而营养的产品。四组酸奶模仿,即CPY-1,CPY-2,CPY-3和CPY-4,使用不同的益生菌培养物制备,包括嗜酸乳杆菌21,植物乳杆菌14和鼠李糖乳杆菌296以及发酵剂。值得注意的是,用植物乳杆菌和鼠李糖乳杆菌培养并孵育12小时的CPY-2表现出最理想的属性。所得酸奶的酸度为0.65%,4.37的pH和6.38logCFU/mL的益生菌计数。逻辑增长模型拟合揭示了最大增长率(k,1/h)和每个CPY变体的最大细菌计数(NmlogCFU/mL)。结果表明,CPY-2显著提高了蛋白质,膳食纤维,与对照相比,酚类和抗氧化能力。扫描电子显微镜显示CPY-2中更结构化和紧凑的酪蛋白网络,突出了其优越的质地特征。总的来说,这项研究表明,将谷物和发芽的假条掺入定型酸奶模拟物中,可通过增加膳食纤维和β-葡聚糖来提供健康益处。
    This study aimed to investigate the integration of cereal and germinated pseudocereals into set-type yogurt mimic, resulting in a novel and nutritious product. Four groups of yogurts mimic, namely CPY-1, CPY-2, CPY-3, and CPY-4, were prepared using different probiotic cultures, including L. acidophilus 21, L. plantarum 14, and L. rhamnosus 296 along with starter cultures. Notably, CPY-2 cultured with L. plantarum and L. rhamnosus and incubated for 12 h exhibited the most desirable attributes. The resulting yogurt demonstrated an acidity of 0.65%, pH of 4.37 and a probiotic count of 6.38 log CFU/mL. The logistic growth model fit revealed maximum growth rates (k, 1/h) and maximum bacterial counts (Nm log CFU/mL) for each CPY variant. The results revealed that CPY-2 significantly improved protein, dietary fiber, phenols and antioxidant capacities compared to the control. Scanning electron microscopy showed more structured and compact casein network in CPY-2, highlighting its superior textural characteristics. Overall, this study demonstrates the incorporation of cereal and germinated pseudocereals into set-type yogurt mimic offers health benefits through increased dietary fiber and β-glucan.

    过去几十年来,富含碳水化合物的谷物消费量的增加导致了人群中代谢紊乱的增加。饮食中的这种营养不平衡可以通过用富含优质蛋白质的假谷物代替谷物来纠正,膳食纤维,不饱和脂肪,和生物活性化合物(例如,多酚和植物甾醇)与谷物相比。这些营养素与许多健康益处有关,如降血脂,抗炎,抗高血压,抗癌,和肝脏保护特性,以及对肥胖和糖尿病的好处。在这次审查中,藜麦的营养成分和保健功效,栀子,将荞麦与小麦进行比较,玉米,和米饭。随后,应用于藜麦的加工处理,栀子,讨论了荞麦及其在食品中的应用。这是相关的,因为对于假鱼和用假鱼配制的功能性食品都存在巨大的市场潜力。尽管有明显的好处,目前的进展由于这些假虫的种植仅限于其本地地区而减慢。因此,为了满足全球需求,必须支持全球范围内种植这些营养丰富的假单胞菌。
    An increase in the consumption of carbohydrate-rich cereals over past few decades has led to increased metabolic disorders in population. This nutritional imbalance in diets may be corrected by substituting cereal grains with pseudocereals that are richer in high-quality proteins, dietary fibers, unsaturated fats, and bioactive compounds (e.g., polyphenols and phytosterols) as compared to cereal grains. These nutrients have been associated with numerous health benefits, such as hypolipidemic, anti-inflammatory, anti-hypertensive, anti-cancer, and hepatoprotective properties, and benefits against obesity and diabetes. In this review, the nutritional composition and health benefits of quinoa, amaranth, and buckwheat are compared against wheat, maize, and rice. Subsequently, the processing treatments applied to quinoa, amaranth, and buckwheat and their applications into food products are discussed. This is relevant since there is substantial market potential for both pseudocereals and functional foods formulated with pseudocereals. Despite clear benefits, the current progress is slowed down by the fact that the cultivation of these pseudocereals is limited to its native regions. Therefore, to meet the global needs, it is imperative to support worldwide cultivation of these nutrient-rich pseudocereals.

    乳糜泻患者往往饮食不均衡,因为无麸质产品通常含有大量的脂肪和碳水化合物以及少量的蛋白质,矿物,和膳食纤维。这项研究的重点是使用假鱼片开发无麸质功能面包,车前子,和无麸质酸面团来代替商业酵母,用辣木强化他们。用酸面团制作了六种不同的无麸质面包:三种对照面包由酸面团区分(藜麦,栀子,和糙米)和三个富含辣木叶的面包,由酸面团区分。抗氧化能力,酚类化合物,营养成分,物理化学参数(颜色,pH值,和酸度),叶酸含量,氨基酸谱,减少糖,矿物成分,矿物质生物可及性,脂肪酸谱,并对感官可接受性进行了评价。在这些分析中包括商业无麸质(COM)面包。与COM面包相比,发现重新配制的面包具有更好的营养特性。辣木叶增加了面包的营养特性,并强调QM(藜麦/辣木)面包的蛋白质增加,纤维,蔗糖,葡萄糖,麦芽糖,苯丙氨酸,还有半胱氨酸.AM(a菜/辣木)面包也显示出更高的总叶酸含量,抗氧化能力,酚类化合物,9t,11t-C18:2(CLA),和9t-C18:1。富含辣木的配方面包可以满足营养要求,并为乳糜泻患者提供健康益处。
    Celiac patients tend to have an unbalanced diet, because gluten-free products typically contain a high amount of fats and carbohydrates and a low amount of proteins, minerals, and dietary fiber. This research focused on the development of gluten-free functional breads using pseudocereals, psyllium, and gluten-free sourdough to replace commercial yeast, fortifying them with Moringa oleifera. Six different gluten-free breads were made with sourdough: three control breads differentiated by sourdough (quinoa, amaranth, and brown rice) and three breads enriched with moringa leaf differentiated by sourdough. The antioxidant capacity, phenolic compounds, nutritional composition, physicochemical parameters (color, pH, and acidity), folate content, amino acid profile, reducing sugars, mineral composition, mineral bioaccessibility, fatty acid profile, and sensory acceptability were evaluated. A commercial gluten-free (COM) bread was included in these analyses. Compared with COM bread, the reformulated breads were found to have better nutritional properties. Moringa leaf increased the nutritional properties of bread, and highlighted the QM (quinoa/moringa) bread as having increased protein, fiber, sucrose, glucose, maltose, phenylalanine, and cysteine. The AM (amaranth/moringa) bread was also shown to have a higher total folate content, antioxidant capacity, phenolic compounds, 9t,11t-C18:2 (CLA), and 9t-C18:1. Reformulated breads enriched with moringa could meet nutritional requirements and provide health benefits to people with celiac disease.

    (伪)谷物已经是人类营养的基础了数千年。各种类型的谷物通常由谷物收获机收获,并且在食用之前必须以不同的方式进行技术处理。除了基因型和生长条件,(假)谷物的组成特征高度依赖于所使用的过程。在本研究中,脱壳的影响,清洁和刷/抛光小麦,拼写,燕麦,大麦,普通荞麦和苦荞麦籽粒及其在物理参数上的分数(千粒重,内核宽度,分数产量)和营养特性(蛋白质,脂肪,β-葡聚糖,宏观和微量元素)进行了调查。谷物样品含有22.7-148.5毫克/克蛋白质,4.5-69.6mg/g脂肪和0.5-54.4mg/gβ-葡聚糖。宏的内容-(K,Mg,P,S,Ca)和微量元素(Mn,Fe,Zn,Na,Cu,Cr,Mo)在研究的(假)谷物及其谷物部分之间差异很大。方差分析表明,物种和部分显着影响了大多数分析特征。然而,可食用部分的组成不显著依赖于刷洗/抛光过程。
    (Pseudo)cereal grains have been the basis of human nutrition for thousands of years. The various types of cereals are usually harvested by grain harvesters and must be technologically processed in different ways before consumption. In addition to genotype and growing conditions, the compositional characteristics of the (pseudo)cereal grains are highly dependent on the processes used. In the present study, the effects of hulling, cleaning and brushing/polishing wheat, spelt, oat, barley, common and Tartary buckwheat grains and their fractions on physical parameters (thousand kernel weight, kernel width, fractional yield) and nutritional characteristics (protein, fat, β-glucan, macro- and microelements) were investigated. Grain samples contained 22.7-148.5 mg/g protein, 4.5-69.6 mg/g fat and 0.5-54.4 mg/g β-glucan. The content of macro- (K, Mg, P, S, Ca) and microelements (Mn, Fe, Zn, Na, Cu, Cr, Mo) varied considerably among the studied (pseudo)cereals and their grain fractions. Analysis of variance showed that species and fractions significantly influenced most of the analyzed characteristics. However, the composition of the edible fractions was not significantly dependent on the brushing/polishing process.

    藜麦和a菜特别令人感兴趣,因为它们越来越多地用于开发具有增强营养价值的新型烘焙产品。这项研究的目的是评估农艺,微生物,以及在意大利南部种植的藜麦和a菜种子的营养特性。出于这个原因,在坎帕尼亚地区的不同试验田中种植了田藜麦和三种a菜(5、12和14),并分析了种植方面,化学成分,和种子的微生物质量。所有种子对地中海盆地实验区的栽培均表现出良好的适应性。藜麦种子的特点是蛋白质含量较高,脂肪,和灰分含量比a菜种子,其特征是它们在膳食纤维中的价值较高。所有的种子,不管生产的地理区域,被酵母菌污染了,模具,和孢子形成细菌,主要是蜡状芽孢杆菌,B.地衣形,safensis和枯草芽孢杆菌,通过16SrRNA测序分析鉴定。所以,芽孢杆菌的检测。必须受到强有力的监控,因为藜麦和a菜种子可以用于面包生产,在那里它们会导致松弛,给各行业造成了巨大的经济损失。
    Quinoa and amaranth are of special interest since they are increasingly used for the development of new bakery products with enhanced nutritional value. The aim of the study was to evaluate the agronomic, microbiological, and nutritional characteristics of quinoa and amaranth seeds grown in Southern Italy. For this reason, quinoa Titicaca and three amaranth accessions (5, 12, and 14) were cultivated in different experimental fields in the Campania Region and analyzed for the cultivation aspects, chemical composition, and microbiological quality of the seeds. All seeds showed a good adaptability to cultivation in the experimental areas of the Mediterranean basin. Quinoa seeds were characterized by their higher protein, fat, and ash content than the amaranth seeds, which were characterized by their higher value in dietary fiber. All seeds, regardless of the geographical area of production, were contaminated with yeasts, moulds, and spore-forming bacteria, mainly Bacillus cereus, B. licheniformis, B. safensis and B. subtilis, as identified by 16S rRNA sequencing analysis. So, the detection of Bacillus spp. must be strongly monitored, as quinoa and amaranth seeds could be used in bread production, where they can cause ropiness, resulting in great economic losses for the industries.

    a菜蛋白的研究受到特别关注。它们的特点是具有很高的生物学价值,大大超过了粮食作物。从a菜面粉生产蛋白质浓缩物包括初步的酶水解,提取所得混合物,蛋白质沉淀,微滤,和冷冻干燥。在我们的研究中,获得的a菜蛋白浓缩物受缬氨酸限制,氨基酸评分为74%。在体内测定的a菜蛋白浓缩物的真实消化率为97.6±0.3%,显著低于酪蛋白(99.3±0.2%)。浓缩物的蛋白质消化率校正的氨基酸评分值为72.2%。获得的浓缩物是丰富的硒来源,铜,镁,锰,和铁。阿魏酸是在a菜蛋白浓缩物中发现的唯一多酚化合物,但其含量明显高于原面粉。在获得a菜蛋白浓缩物的过程中,皂甙没有完全去除。我们在浓缩物中鉴定出15种皂苷,主要是bidesmoside型,其中皂苷元是齐墩果酸的相关衍生物。因此,所开发的a菜蛋白浓缩物可用作功能性食品中的成分,具有很高的生物学价值。
    Special attention is being paid to the study of amaranth proteins. They are characterized by a high biological value that significantly exceeds those of grain crops. The production of protein concentrate from amaranth flour includes preliminary enzymatic hydrolysis, extraction of the resulting mixture, protein precipitation, microfiltration, and freeze-drying. In our study, the obtained amaranth protein concentrate was limited by valine, with an amino acid score of 74%. The true digestibility of the amaranth protein concentrate determined in vivo was 97.6 ± 0.3%, which was significantly lower than that of casein (99.3 ± 0.2%). The protein digestibility-corrected amino acid score value of the concentrate was 72.2%. The obtained concentrate was a rich source of selenium, copper, magnesium, manganese, and iron. Ferulic acid was the only polyphenolic compound found in the amaranth protein concentrate, but its content was significantly greater compared to the original flour. Saponins were not removed completely during the process of obtaining the amaranth protein concentrate. We identified 15 saponins in the concentrate, mainly of the bidesmoside type, the sapogenins of which are related derivatives of oleanolic acid. Thus, the developed amaranth protein concentrate can be used as an ingredient in functional food products, with a high biological value.

    藜麦(藜藜麦。)地位最近从局限于其原产地的主食作物提高到全球公认的商业粮食作物,在国际市场上广泛交易。食品标签上的声明可能会吸引消费者,因此他们可以购买营养产品,过敏/不耐受,或社会和道德主张,努力做出更健康、更可持续的食物选择。这项工作的目的是(i)调查意大利消费者在电子商务市场上可获得的藜麦食品的营养质量,从营养标签中看出,(ii)询问营养的发生,过敏和不耐受,以及包装上的社会和道德主张。为了这个目标,对意大利市场上的藜麦食品进行了横断面调查。出现了几种藜麦产品类别,谷物和面食是主要的。营养主张通常与无麸质和社会/道德主张相结合。根据营养事实,较高比例的产品符合营养要求。无麸质标记的藜麦和含麸质的藜麦产品之间的比较显示出营养品质的有限差异。
    Quinoa\'s (Chenopodium quinoa Willd.) status has been recently raised from staple food crop confined to its region of origin to a globally recognized commercial food crop, widely traded in the international market. Claims on food labels may attract consumers who can therefore purchase products with nutrition, allergy/intolerance, or social and ethical claims in an effort to make healthier and more sustainable food choices. The aim of this work was (i) to investigate the nutritional quality of quinoa food products available to the Italian consumer over the e-commerce market, as emerged from nutrition labelling, and (ii) to inquire about the occurrence of nutrition, allergy and intolerance, and social and ethical claims on the packaging. To this aim, a cross-sectional survey of quinoa food products available in the Italian market was conducted. It emerged that several quinoa product categories are available and grains and pasta are the major ones. Nutrition claims are generally displayed in combination with gluten-free and social/ethical claims. Based on the nutrition facts, a higher proportion of products are eligible for nutrition claims. The comparison between the gluten-free labelled and gluten-containing quinoa products showed limited differences in the nutritional quality.

    评估无麸质食品的营养质量和热损伤效应对于确保麸质不耐受或乳糜泻患者能够安全地满足他们的需求至关重要。在这项工作中,由谷物制成的十五个不同的商业无麸质面食样品,伪像,和脉冲,单独或混合组合,进行分析以评估其营养价值,必需氨基酸组成,和蛋白质化学评分。研究了美拉德反应的发生,和热处理标记物(呋喃,麦芽酮糖,羟甲基糠醛,和葡萄糖连糖醇)进行了测定。对糠素值的分析表明,用相同原料制成的面食会产生不同程度的热损伤。在任何测试的样品中,没有证据表明美拉德反应在晚期进行。最后,麦芽酮糖和糠氨酸水平之间的相关性证明了将这两种标记物结合起来评估热损伤程度的有效性。
    Evaluating the nutritional quality and thermal damage effects of gluten-free foods is essential to ensure that people with gluten intolerance or celiac disease can safely meet their needs. In this work, fifteen different commercial gluten-free pasta samples made from cereals, pseudocereals, and pulses, alone or in mixed combinations, were analyzed to assess their nutritional value, essential amino acids composition, and protein chemical score. The occurrence of the Maillard reaction was investigated, and the levels of heat treatment markers (furosine, maltulose, hydroxymethylfurfural, and glucosylisomaltol) were determined. Analysis of the furosine values showed that pasta made with the same raw materials can have different degrees of thermal damage. There was no evidence of the Maillard reaction progressing in the advanced phase in any of the samples tested. Finally, the correlation between maltulose and furosine levels demonstrated the usefulness of combining the two markers to assess the extent of thermal damage.

    许多植物的发芽种子是物质的天然来源,可用于补充食物并增加其功能。种子的新陈代谢可以在发芽过程中改变以产生特定的促进健康的化合物。苦瓜是营养丰富的来源。发芽过程中改性的荞麦种子可能有助于作为具有抗动脉粥样硬化特性的新型功能性食品的添加剂。然而,其效果和安全性应在体内研究中进行评估.该研究的目的是评估在致动脉粥样硬化(高脂肪)饮食中添加改良荞麦芽(FagopyrumesculentumMoench)对大鼠形态和消化率参数的影响。通过添加酿酒酵母var的益生菌菌株来修饰荞麦种子。布拉迪尼.这项研究是在32只Wistar大鼠身上进行的,在实验过程中评估消化率和血细胞计数。没有证据表明对动物的体重增加和营养效率有不利影响。然而,注意到冻干荞麦芽对消化率和形态参数的影响。在添加豆芽的高脂肪饮食组中,脂肪消化率在统计学上显着下降。该研究为荞麦芽的使用提供了新的方向。
    The germinated seeds of many plants are a natural source of substances that can be used to supplement food and increase its functionality. The seeds\' metabolism may be modified during germination to produce specific health-promoting compounds. Fagopyrum esculentum Moench is a rich source of nutrients. Buckwheat seeds modified during germination may be helpful as an additive to new functional food products with anti-atherogenic properties. However, their effect and safety should be assessed in in vivo studies. The aim of the study was to evaluate the effect that adding modified buckwheat sprouts (Fagopyrum esculentum Moench) to an atherogenic (high-fat) diet has on the morphology and digestibility parameters of rats. Buckwheat seeds were modified by adding the probiotic strain of the yeast Saccharomyces cerevisiae var. boulardii. The study was carried out on 32 Wistar rats, and digestibility and blood counts were assessed during the experiment. There was no evidence of an adverse effect on the animals\' weight gain and nutritional efficiency. However, the influence of diets with freeze-dried buckwheat sprouts on digestibility and morphological parameters was noticed. Fat digestibility registered a statistically significant decrease in the groups fed a high-fat diet with the addition of sprouts. The study shows a new direction in the use of buckwheat sprouts.
