Almond oil: A comprehensive review of chemical composition,extraction methods,preservation conditions,potential health benefits,and safety

Almond oil, a rich source of macronutrients and micronutrients, is extracted for food flavorings and the cosmetics industry. In recent years, the need for high-quality and high-quantity production of almond oil for human consumption has been increased. The present review examines the chemical composition of almond oil, storage conditions, and clinical evidence supporting the health benefits of almond oil. From the reviewed studies, it appears that almond oil contains a significant proportion of poly and monounsaturated fatty acids, with oleic acid as the main compound, and an important amount of tocopherol and phytosterol content. Some variations in almond oil composition can be found depending on the kernel's origin and the extraction system used. Some new technologies such as ultrasonic-assisted extraction, supercritical fluid extraction, subcritical fluid extraction, and salt-assisted aqueous extraction have emerged as the most promising extraction techniques that allow eco-friendly and effective recovery of almond oil. This safe oil was reported by several clinical studies to have potential roles in cardiovascular risk management, glucose homeostasis, oxidative stress reduction, neuroprotection, and many dermatologic and cosmetic applications. However, the anticarcinogenic and fertility benefits of almond oil have yet to be experimentally verified.

Edible insects – defining knowledge gaps in biological and ethical considerations of entomophagy

ABSTRACT

While seeking novel food sources to feed the increasing population of the globe, several alternatives have been discussed, including algae, fungi or in vitro meat. The increasingly propagated usage of farmed insects for human nutrition raises issues regarding food safety, consumer information and animal protection. In line with law, insects like any other animals must not be reared or manipulated in a way that inflicts unnecessary pain, distress or harm on them. Currently, there is a great need for research in the area of insect welfare, especially regarding species-specific needs, health, farming systems and humane methods of killing. Recent results from neurophysiological, neuroanatomical and behavioral sciences prompt caution when denying consciousness and therefore the likelihood of presence of pain and suffering or something closely related to it to insects. From an animal protection point of view, these issues should be satisfyingly solved before propagating and establishing intensive husbandry systems for insects as a new type of mini-livestock factory farming.     

致敏大豆蛋白P34及其清除方法的研究进展

大豆作为"八大"过敏食品之一,其过敏患者数量约占食物过敏总人数的25%。如何降低大豆产品的致敏性,保证消费者的安全,已经成为食品安全领域一个热议的话题。大豆中含有多种致敏因子,如Gly-m Bd 30K蛋白、Gly-m Bd 28K蛋白和Gly-m Bd 28K蛋白等。其中Gly-m Bd 30K蛋白作为致敏性最强的过敏原,能被65%的大豆过敏患者血清识别,在几种过敏蛋白中占着较突出的地位。本文综述了Gly-m Bd 30K蛋白的抗原表位、去除方法的研究现状。其中,酶法处理、超高压法、挤压膨化法等降低大豆致敏性的研究已取得了一定的成果,这为进一步提高大豆及其制品的品质质量,保证其在食品工业和畜牧业方面的安全利用提供了科学参考。     

药用/工业用转基因植物数据库的构建

药用/工业用转基因植物已经成为转基因生物新的增长点。本研究收集了以植物作为生物反应器生产药用/工业用产品的数据信息300多份,转化事件近200条,并完成信息上传108条。每个转化事件收集了包括外源蛋白表达量、毒性、致敏性、临床数据、安全等级在内的20多种信息。利用Linux Apache Mysql PHP （LAMP）架构首次设计了药用/工业用转基因植物数据库,面向用户不同需求设计了初级检索和高级检索两种检索方式。该数据库具有综合性、专业性、实用性和首创性的特点,为药用/工业用转基因植物新品种的研发提供信息帮助,为政府机构审批和监管以及制定其安全评价标准提供技术支撑。
