Abstract Nowadays, consumers demand high-quality and fresh-like food products. In the fruit juices industry, the applied processes to guarantee safety and increase shelf life often negatively impact final product quality. Although thermal treatments are the most frequently applied processes to preserve fruit juices, heating may induce undesirable changes in sensory and nutritional characteristics. These facts prompted research on alternative and mild-non-thermal processes that assure the quality and safety of this type of liquid food. In this context, UV-C light has emerged, presenting several characteristics that make it a promising alternative to traditional processing and appropriate for liquid foods. UV-C light attributes and their application in the food industry are described in this work. Due to the recognized potential of this non-thermal technology on fruit juices, numerous researchers have been focusing on this subject. A compilation of those works is presented and discussed, emphasizing the UV-C light impact on quality/nutritional aspects and microbial inactivation in fruit juices. This critical review paper aims to be a valuable tool for finding characteristics/conditions of UV-C treatments and determine the corresponding impact on quality and safety parameters of fruit juices, opening topics for further research.
如今,消费者对高品质、新鲜的食品有着强烈的需求。在果汁行业中,为了保证安全性和延长保质期而采用的工艺往往会对最终产品质量产生负面影响。虽然热处理是保存果汁最常用的方法,但加热可能会引起感官和营养特性的不良变化。这些事实促使研究替代和温和的非热工艺,以确保这类液体食品的质量和安全。在这种情况下,UV-C光出现了,呈现出几个特性,使其成为传统加工的有希望的替代品,适用于液体食品。本文介绍了UV-C光的特性及其在食品工业中的应用。由于认识到这种非热技术对果汁的潜力,许多研究人员一直在关注这一主题。本文介绍和讨论了这些工作的汇编,强调了UV-C光对果汁质量/营养方面和微生物失活的影响。这篇重要的综述论文旨在为发现UV-C处理的特征/条件,确定相应的对果汁质量和安全参数的影响,开辟进一步研究的课题提供有价值的工具。

Abstract Meat is a perishable product due to its protein and high-water activity (Aw) and is thus prone to microbial and oxidative processes, which lead to spoilage and undesirable changes in meat physicochemical characteristics. Edible coatings, combined with antioxidant and antimicrobial substances, have been used to improve meat shelf life by creating an oxygen barrier against lipid oxidation, acting as an antimicrobial agent, and to keep meat color. Here, we reviewed the use of active edible coatings and their effects on physicochemical and sensory characteristics of chicken, pork, beef, lamb meat, and fish.
肉类是一种易腐产品,由于其蛋白质和高水分活性(Aw),因此容易受到微生物和氧化过程的影响,从而导致腐败和肉类物理化学特性的不良变化。可食用涂层与抗氧化和抗菌物质相结合,通过形成氧气屏障来防止脂质氧化,作为抗微生物剂,并保持肉的颜色,从而延长肉的保质期。本文综述了活性食用涂层的应用及其对鸡肉、猪肉、牛肉、羊肉和鱼类的理化和感官特性的影响。

Abstract The basic tenet of crop improvement is the novel genetic variability that is achieved through selection, hybridization, mutation and recombination. The new technological innovations of plant breeding offer scope for transforming crop improvement with more precision and resolution. Advances in genomic-based tools and high-throughput phenotyping have enabled the analysis of genetic variation and identification of molecular signatures of agronomic traits. Molecular markers and molecular-marker-assisted breeding have facilitated the speedy selection of new, novel genetic combinations in breeding for high-yielding, stress-tolerant and nutritionally enriched crops. Transgenic methods have revolutionized modification for stress tolerance and higher productivity, and several genetically modified crops are under cultivation. Availability of genome sequencing platforms and genomic resources has significantly contributed to accessing novel genes and validating their functions. Genome-editing tools and recent advances of prime editing are now accessible for precise genetic alteration of plant traits. The new plant breeding tools will certainly foster development of highly productive, improved crop varieties for achieving food security and climate resilience.
作物改良的基本原则是通过选择、杂交、突变和重组获得新的遗传变异。植物育种的新技术创新为作物改良提供了更高的精度和分辨率。基于基因组学的工具和高通量表型的进步使遗传变异分析和农艺性状的分子特征鉴定成为可能。分子标记和分子标记辅助育种促进了在高产、耐胁迫和营养丰富作物育种中快速选择新的、新的遗传组合。转基因方法已经彻底改变了转基因技术,使其具有抗逆性和更高的生产力,并且有几种转基因作物正在种植中。基因组测序平台和基因组资源的可用性为获取新基因和验证其功能做出了重大贡献。基因组编辑工具和引体编辑的最新进展现在可以用于精确的植物性状遗传改变。新的植物育种工具肯定会促进高产、改良作物品种的发展,从而实现粮食安全和气候适应能力。

Abstract MicroRNAs (miRNAs) were envisioned, in recent years, as alternative, environmental friendly molecular tools to confer crop protection. This view was based on their ability to move across Kingdoms and to modulate gene expression at the post-transcriptional level, inhibiting pathogens or parasites' invasive processes or promoting plant favorable microorganisms. Strategies based on miRNAs, complementing the already existing technologies or creating new unexplored ones, are expected to provide valuable tools to reduce crop biotic damage, increasing food production and safety. This review provides a brief overview of miRNA-based technologies applied so far for plant protection and reports some new approaches suggested by recent acquisitions on miRNA.
摘要:近年来,人们设想MicroRNAs (miRNAs)作为一种可替代的、环境友好的分子工具来赋予作物保护。这种观点是基于它们跨越王国的能力,并在转录后水平调节基因表达,抑制病原体或寄生虫的入侵过程或促进植物有利微生物。基于mirna的策略,补充现有技术或创造新的未开发技术,有望为减少作物生物损害、增加粮食生产和安全提供有价值的工具。本文综述了迄今为止基于miRNA的植物保护技术的应用情况,并报道了近年来miRNA研究的一些新方法。

Abstract At its 10th meeting in 2010, the Conference of the Parties of the CBD adopted the 'Nagoya Protocol (NP) on access to genetic resources and the fair and equitable sharing of benefits arising from their utilisation' which entered into force on 12 October 2014. Currently, the NP has been adopted by 129 parties, including the EU. This article reviews information retrieved from a variety of different sources dealing with the implications of Access and Benefit Sharing (ABS) regulations, including the NP, for biological collections, especially regarding material accession, conservation and research in botanic gardens. Problems encountered with adhering to ABS regulations and the NP include the following: increasing bureaucratic and administrative burdens arising from the many different ABS-related regulations at the national level; difficulties in identifying and engaging with national authorities designated as competent signatories for the NP in user and provider countries; and problems arising from ambivalent and inconsistent use of terms in the NP and in national ABS legislation. The authors encourage parties to fulfil the CBD requirement for 'simplified measures on access for non-commercial research purposes' and point out that NP-related impediments to conservation (and fundamental research) will have negative impacts on human development and biodiversity.
在2010年第10次缔约方大会上,《生物多样性公约》缔约方大会通过了《关于获取遗传资源和公平公正分享利用遗传资源所产生惠益的名古屋议定书》,该议定书于2014年10月12日生效。目前,包括欧盟在内的129个政党都采用了国家党。本文综述了从各种不同来源检索到的信息,涉及包括NP在内的获取和利益分享(ABS)法规对生物收藏的影响,特别是关于植物园材料的获取、保护和研究。在遵守ABS法规和NP方面遇到的问题包括:由于国家一级许多不同的ABS相关法规而增加的官僚主义和行政负担;在使用者和提供者国家查明并与指定为NP主管签署国的国家当局接触方面存在困难;以及NP和国家ABS立法中术语使用的矛盾和不一致所产生的问题。这组作者鼓励缔约方履行《生物多样性公约》关于“非商业研究目的获取的简化措施”的要求,并指出与np相关的保护(和基础研究)障碍将对人类发展和生物多样性产生负面影响。

Abstract The longhorn date palm stem borer, Jebusaea hammerschmidtii Reiche has become an important pest that causes economic damage in date palm groves. The beetle has established itself in many date palm-producing countries as one of the most important biotic factors that threatens date palm cultivation and genetic diversity. The larvae of the longhorn stem borer, the destructive stage, are endophytic developing inside the date palm tissues. This article consolidates the scant literature on the beetle biology, ecology, economic impact, possible field management measures, and future research priorities.

Abstract The quality and safety of pepper (Piper nigrum L.) are a function of crop management practices, harvest maturity, harvesting methods and subsequent handling after harvest, including storage conditions and processing methods. The review shows that volatile oil decreases with shade intensity (15-30%). Essential oil, oleoresin, piperine and monoterpenes (thujene, α-pinene, sabinene, limonene, α-phellandrene and linalool) increase with altitude, while β-caryophyllene and total phenol decrease with increase in altitude. Fermentation of ripe pepper fruits forms odorants (butanoic acid, 3-methylindole, and 4-methylphenol) attributing intense faecal/shed-like off-flavour white pepper powder. Low-drying temperature (≤56°C) and duration (≤3 hrs) lead to low bulk density (0.17 g/ml) and low moisture loss (31%). Excessive soaking of black peppercorns prior to mechanical decortication reduces volatile oil and increases moisture content and broken berries. Availability of heavy metals in grinding machines increases the level of heavy metals; Fe (69.8-1147 mg/kg), Pb (21.3-947 μg/kg) and V (64.1-1072 μg/kg) in pepper powder. Storing peppercorns along with other materials enhances cross-contamination of heavy metals; Pb, Cd and Cr. High moisture content (> 13%) and farmers' unawareness resulted in high (2200 to > 30000 cfu/g) mycotoxins contamination. Environmental and industrial pollutants such as plasticizers, bisphenol A, polycyclic aromatic hydrocarbons and pesticides are also pepper contaminants of high merit. Radiofrequency pasteurization, vacuum-assisted steaming, ethylene oxide fumigation, atmospheric pressure plasma, dry heat sterilization, gamma-irradiation and ultraviolet-C light treatments are among strategies to enhance the quality and safety of pepper. More precautions also have to be taken to regulate the shade, drying temperature and duration, soaking duration, hygienic processing and storage in order to retain quality, minimize the risk of microbial or chemical contaminations and comply with standards.
辣椒(Piper nigrum L.)的质量和安全是作物管理实践、收获成熟度、收获方法和收获后的后续处理(包括储存条件和加工方法)的函数。结果表明,随着遮荫强度的增大,挥发油含量降低(15-30%)。精油、油树脂、胡椒碱和单萜(苏烯、α-蒎烯、sabinene、柠檬烯、α-茶树烯和芳樟醇)随海拔升高而升高,而β-石竹烯和总酚随海拔升高而降低。成熟的胡椒果实发酵形成气味(丁酸,3-甲基吲哚和4-甲基苯酚),导致强烈的粪便/牛粪味白胡椒粉末。低干燥温度(≤56℃)和持续时间(≤3小时)导致低堆积密度(0.17 g/ml)和低水分损失率(31%)。在机械去皮之前过度浸泡黑胡椒会减少挥发油,增加水分含量和破碎的浆果。磨床中重金属的可用性增加了重金属水平;胡椒粉中的铁(69.8 ~ 1147 mg/kg)、铅(21.3 ~ 947 μg/kg)、钒(64.1 ~ 1072 μg/kg)。将胡椒与其他材料一起储存会增加重金属的交叉污染;高含水量(> 13%)和农民不知情导致真菌毒素污染高(2200 ~ > 30000 cfu/g)。增塑剂、双酚A、多环芳烃和农药等环境和工业污染物也是辣椒污染物。射频巴氏杀菌、真空辅助蒸煮、环氧乙烷熏蒸、常压等离子体、干热杀菌、γ辐照和紫外- c光处理是提高辣椒质量和安全的策略。还必须采取更多的预防措施来调节阴影,干燥温度和持续时间,浸泡时间,卫生处理和储存,以保持质量,最大限度地减少微生物或化学污染的风险,并符合标准。

What is happening to insect numbers, and what does it mean? 昆虫数量发生了什么变化?这意味着什么?

Abstract Reports of declines in abundance of a number of insect species have been increasing over the last two decades. These have variously been attributed to climate change, urbanisation, deforestation, agricultural intensification, habitat fragmentation and pesticide usage. The picture has been complicated by the fact that not all insect groups have shown the drastic declines reported for others, flawed methodology, paucity of long-term studies, the lack of data from the tropics with most long-term studies emanating from Europe and North America. In addition, the number of insect groups studied has largely been restricted to charismatic species such as Hymenoptera, Lepidoptera, Coleoptera and Odonata. Despite this, the evidence for long-term declines in insect abundance is incontrovertible. To aid in our understanding of the problem we need to set up more globally coordinated studies, use past data in innovative ways and convince policy makers and governments to support these studies.
在过去的二十年里,关于一些昆虫物种丰度下降的报道越来越多。气候变化、城市化、森林砍伐、农业集约化、栖息地破碎化和农药使用是造成这些问题的不同原因。并不是所有的昆虫种群都显示出其他昆虫种群的急剧下降,方法有缺陷,缺乏长期研究,缺乏热带地区的数据,大多数长期研究来自欧洲和北美,这些事实使情况变得更加复杂。此外,研究的昆虫类群数量主要局限于膜翅目、鳞翅目、鞘翅目和翅翅目等魅力型物种。尽管如此,昆虫数量长期下降的证据是无可争议的。为了帮助我们理解这个问题,我们需要建立更多的全球协调研究,以创新的方式使用过去的数据,并说服决策者和政府支持这些研究。

To aid in our understanding of the problem we need to set up more globally coordinated studies, use past data in innovative ways and convince policy makers and governments to support these studies.","PeriodicalId":39273,"journal":{"name":"CAB Reviews: Perspectives in Agriculture, Veterinary Science, Nutrition and Natural Resources","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84210231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract The emergence and re-emergence of infectious diseases including zoonoses and persistence of neglected zoonotic diseases threaten the global health and economy of rural societies now more than any time in the history of humanity. Animals are the main reservoirs of zoonotic disease agents, and zoonotic pathogens are transmitted to humans by direct contacts with infected animals or indirectly through animal products and the environment. A range of factors contribute in persistence and emergence of zoonoses, and globalization, climate change, and lack of proper coordination among the governmental organization responsible for human and animal health are the key indicators. Given the shared nature of zoonotic diseases and the spread, emergence, and re-emergence of zoonotic diseases in human and animal populations, integrated One Health is the only effective approach to solve this most important health issue. In this article, different aspects of zoonotic diseases, their role in incremental poverty, and the needs for integrated activities for their control and management are reviewed and discussed in detail.
包括人畜共患病在内的传染病的出现和再次出现以及被忽视的人畜共患病的持续存在比人类历史上任何时候都更严重地威胁着全球卫生和农村社会的经济。动物是人畜共患疾病病原体的主要宿主,人畜共患病原体通过与受感染动物的直接接触或通过动物产品和环境间接传播给人类。造成人畜共患病持续存在和出现的因素有很多,全球化、气候变化以及负责人类和动物卫生的政府组织之间缺乏适当协调是关键指标。鉴于人畜共患疾病的共同性质,以及人畜共患疾病在人类和动物群体中的传播、出现和再次出现,一体化的“同一个健康”是解决这一最重要健康问题的唯一有效方法。在本文中,详细审查和讨论了人畜共患疾病的不同方面、它们在增加贫困中的作用以及为控制和管理人畜共患疾病而开展综合活动的必要性。

5 With the impact of climate change becoming increasingly apparent, there have been calls for 6 world leaders to take measures aimed at mitigating the potential effect on the environment of 7 the rapid expansion in human population, urbanisation, deforestation, agricultural 8 development, industrialisation and the rampant burning of fossil fuels. This paper reviews 9 literature on the spiritual dimensions of environmental sustainability from an Islamic 10 perspective, with emphasis on the sustainable utilisation of agricultural resources linked to 11 production and consumption. The religious standpoint on stewardship of nature ( Khilafa ), 12 climate change and animal welfare are explored from within the Islamic scriptures to gain a 13 better understanding of sustainable development from an Islamic perspective, particularly with 14 regard to meat production. The description of humans as stewards or guardians of nature in 15 Islamic literature is a direct call from God for humanity to safeguard the natural capital in order 16 to maintain synergistic relationship between flora, fauna and other biodiversity. 17
随着气候变化的影响越来越明显,人们呼吁世界各国领导人采取措施,以减轻人口迅速增长、城市化、森林砍伐、农业发展、工业化和化石燃料的猖獗燃烧对环境的潜在影响。本文从伊斯兰的角度回顾了有关环境可持续性精神层面的文献,重点是与生产和消费相关的农业资源的可持续利用。宗教对自然管理(Khilafa)、气候变化和动物福利的立场从伊斯兰经文中进行了探讨,以从伊斯兰的角度更好地理解可持续发展,特别是在肉类生产方面。在伊斯兰文献中,人类被描述为自然的管家或守护者,这是真主直接呼吁人类保护自然资本,以维持植物、动物和其他生物多样性之间的协同关系。17
