Strawberry Production in Central Europe     

《International Journal of Fruit Science》2013,13(1):91-105

Abstract

This paper focuses on the cropping systems in central European countries such as Belgium, The Netherlands, UK, Ireland, Germany, Switzerland and the northern part of France and Italy. During the last decade there has been a consistent increase in programmed “out-of-season” strawberry production in several central European countries. This is being achieved in part, by using cultivars with different cropping seasons, but mainly by sequential planting of cold-stored plants and by growing strawberries in greenhouses and plastic tunnels. These methods have made it possible to extend the strawberry production for 11 months, from the end of February until mid January in central European countries with moderate climates.  相似文献   

Shelf-Life of Spanish Mackerel (Scomberomorus commerson) from Northern Australian Waters     

《Journal Of Aquatic Food Product Technology》2013,22(4):63-79

Abstract

The shelf-life of Spanish mackerel caught by line fishing in Northern Australian waters was evaluated. Spiked fish were stored in ice either headed and gutted or left uncut and subjected to sensory, nucleotide, pH, histamine and microbial analysts and the rigor pattern recorded. There was little difference between the two product forms. Rigor in uncut fish lasted for 14 ± 9.8 hours and in headed and gutted fish for 19.6 ± 16.3 hours. Spanish mackerel retained good sensory quality for up to 14 days. The bacterial load reached 105 cfu/g by 18 days. K values were low for most of the storage time, < 40%. Histamine levels did not develop more than 10 mg/kg during storage. The pH of Spanish mackerel did not change much even though bacterial levels become high.  相似文献

疫情下乳制品需求旺盛,低温鲜奶市场蓬勃发展     

杨祯妮  王加启  马广旭  程广燕 《中国乳业》2021,(7):13-17

2020年新冠肺炎疫情（简称“疫情”）爆发后,我国乳制品消费量一度下降,随着疫情逐步得到控制,液态乳制品销售量于4月后开始恢复为同比正向增长,此后乳制品消费总量加快增长,消费结构不断优化,尤其是低温鲜奶消费一枝独秀。近年来,我国低温鲜奶消费呈加速增长趋势,2020年同比增幅达25.6%,增速创历史新高。总的看,近年来在政策鼓励、技术创新、市场培育三大因素推动下,低温鲜奶消费持续较快增长,而疫情下消费者对营养健康的关注度提高大大助推了这一进程,预计这一趋势仍将持续,建议顺应消费升级趋势,加大奶源生产基地和冷链设施建设,构筑乳业高质量发展的基础。  相似文献   

Thermal biology and locomotor performance in Phymaturus calcogaster: are Patagonian lizards vulnerable to climate change?     

Rosa L. OBREGÓN  Jose A. SCOLARO  Nora R. IBARGÜENGOYTÍA  Marlin MEDINA 《Integrative zoology》2021,16(1):53-66

Behavioral and physiological traits of ectotherms are especially sensitive to fluctuations of environmental temperature. In particular, niche-specialist lizards are dependent on their physiological plasticity to adjust to changing environmental conditions. Lizards of the genus Phymaturus are viviparous, mainly herbivorous, and inhabit only rock promontories in the steppe environments of Patagonia and the Andes. Herein, we examine the vulnerability of the southernmost Phymaturus species to global warming: the endemic Phymaturus calcogaster, which lives in a mesic environment in eastern Patagonia. We studied body temperatures in the field (T_b), preferred body temperatures in a thermogradient (T_pref), the operative (T_e) and environmental temperatures, and the dependence of running performance on body temperature. P. calcogaster had a mean T_b (27.04°C) and a mean T_e (31.15°C) both lower than their preferred temperature (T_pref = 36.61°C) and the optimal temperature for running performance (T_o = 37.13°C). Lizard activity seems to be restraint during the early afternoon due high environmental temperatures. However, both, the high safety margin and warming tolerance suggest that the expected increase in environmental temperatures due to global warming (IPCC report in 2018) would not threaten, but indeed enhance locomotor performance in this population.  相似文献   

寒冷地区草原有毒有害牧草监测与防治     

周忠义 《畜牧兽医科学(电子版)》2021,(4):108-109

草原是内蒙古地区草食畜牧养殖产业健康发展的基础,同时也是优质牧草的主要来源。有毒有害牧草生长扩散预示着草场退化,对当地草食畜牧养殖产业健康发展会造成毁灭性打击。有毒有害植物生长发育,不仅会危害牲畜健康且还会严重消耗土壤的水分和养分,妨碍优良牧草繁殖生长,使草场产量和质量显著下降。在长时间草场利用过程中,很多农牧民群众只注重索取,不注重生态环境保护,使草场生产能力和抵抗能力逐渐变差,给有毒有害牧草繁殖生长提供了条件。因此需要加强寒冷地区草原有毒有害牧草的监测,并采取针对性措施进行防控,降低发病率。该文主要探讨内蒙古呼伦贝尔市寒冷地区草原有毒有害牧草的种类,并提出相应的防治措施。  相似文献

食品安全与食品低温流通中的温度监控     

徐倩  谢晶 《上海海洋大学学报》2007,(2):180-184

食品的温度监控是一种有效的保证食品安全及保持冷藏链完整的手段,对冷冻冷藏食品在低温流通过程中实行温度监控是非常有必要的。目前,我国冷藏运输中的温度管理情况并不乐观,消费者获得的货物通常不能达到预计的要求。要解决这一问题,必须要借助于时间-温度指示器等来对其整个运输过程进行温度监控。本文对温度立法的必然性和前景,温度监控的重要性、原理以及在冷藏运输中的应用作了较详尽的介绍,并列举了几种国外时间-温度指示器的工作原理。  相似文献
