    木材腐烂真菌(WDF)是专门降解木材的真菌。一个有趣的观点是它们用作新型食品或食品成分的来源。这里,第一次,来自A.biennis的水醇和有机提取物的代谢物谱,F.伊贝丽卡,通过NMR方法研究了陆生菌丝体。氨基酸(丙氨酸,精氨酸天冬酰胺,天冬氨酸,甜菜碱,GABA,谷氨酸,谷氨酰胺,组氨酸,异亮氨酸,亮氨酸,赖氨酸,苯丙氨酸,苏氨酸,色氨酸,酪氨酸,缬氨酸),糖(半乳糖,葡萄糖,麦芽糖,海藻糖,甘露醇),有机酸(乙酸,柠檬酸盐甲酸盐,富马酸盐,乳酸,苹果酸,琥珀酸盐),腺苷,胆碱,在水醇提取物中鉴定和定量尿嘧啶和尿苷,而有机提取物的1H光谱显示存在饱和,单不饱和和二不饱和脂肪链,麦角固醇,1,2-二酰基-sn-甘油-3-磷脂酰乙醇胺,和1,2-二酰基-sasgamcilo-3-磷脂酰胆碱。双叶酵母提取物显示出最高的氨基酸浓度。一些化合物仅在特定物种中检测到:甜菜碱和甘露醇。A.biennis中的麦芽糖,伊贝里卡的半乳糖,在F.iberica和S.hirsutum的GABA,和乙酸盐在A.biennis和S.hirsutum。美国陆生显示出最高的饱和脂肪链浓度,而DUFA在A.biennis中达到最高浓度。在双歧杆菌和伊贝里卡中都测量到大量的麦角甾醇。报告的结果可用于开发具有高营养和营养保健价值的基于WDF的产品。
    Wood Decay Fungi (WDF) are fungi specialized in degrading wood. An interesting perspective is their use as a source of Novel Foods or food ingredients. Here, for the first time, the metabolite profiling of hydroalcoholic and organic extracts from A. biennis, F. iberica, S. hirsutum mycelia was investigated by NMR methodology. Amino acids (alanine, arginine, asparagine, aspartate, betaine, GABA, glutamate, glutamine, histidine, isoleucine, leucine, lysine, phenylalanine, threonine, tryptophan, tyrosine, valine), sugars (galactose, glucose, maltose, trehalose, mannitol), organic acids (acetate, citrate, formate, fumarate, lactate, malate, succinate), adenosine, choline, uracil and uridine were identified and quantified in the hydroalcoholic extracts, whereas the 1H spectra of organic extracts showed the presence of saturated, mono-unsaturated and di-unsaturated fatty chains, ergosterol,1,2-diacyl-sn-glycero-3-phosphatidylethanolamine, and 1,2-diacyl-sasglycero-3-phosphatidylcholine. A. biennis extracts showed the highest amino acid concentration. Some compounds were detected only in specific species: betaine and mannitol in S. hirsutum, maltose in A. biennis, galactose in F. iberica, GABA in F. iberica and S. hirsutum, and acetate in A. biennis and S. hirsutum. S. hirsutum showed the highest saturated fatty chain concentration, whereas DUFA reached the highest concentration in A. biennis. A high amount of ergosterol was measured both in A. biennis and F. iberica. The reported results can be useful in the development of WDF-based products with a high nutritional and nutraceutical value.

    本研究旨在评估一种由丝状真菌中间神经孢子菌制成的新型真菌产品,在面包残留物上种植,是使用问卷感知的。要求参与者对真菌汉堡肉饼的特征属性进行评分,并在将其与Quorn和汉堡肉饼进行比较时陈述他们的偏好。对数据进行分析,以评估性别或年龄是否与偏好状况有统计学关联。关于汉堡肉饼的比较,年龄和性别与偏好概况无关。除了年龄和苦涩,年龄和性别也与关于真菌汉堡肉饼的感官特征的偏好概况无关。大多数参与者喜欢真菌汉堡肉饼的特征。结果表明,当信息传播以环境效益为目标时,废物中的真菌产品可以成为公认的产品。此外,被商业接受,应改善产品的咀嚼性和苦味。其他改进应针对整体口味,以迎合喜欢肉类蛋白质来源的人。
    The current study aims to assess how a novel fungi product made from the filamentous fungus Neurospora intermedia, cultivated on bread residuals, is perceived using questionnaires. Participants were asked to rate characteristic attributes of a fungi burger patty and state their preference when comparing it to Quorn and hamburger patties. The data were analyzed to assess whether gender or age was statistically associated with preference profiles. Neither age nor gender was associated with the preference profiles regarding the comparison of burger patties. Except for age and bitterness, age and gender were also not associated with the preference profiles regarding the sensory characteristics of the fungi burger patty. Most of the participants liked the characteristics of the fungi burger patty. The results indicate that fungi products from waste can become accepted products when information dissemination targets environmental benefits. Moreover, to be commercially accepted, the chewiness and bitterness of the product should be improved. Other improvements should target the overall taste in order to cater to people who prefer meat-based protein sources.

    目前全球肉类生产体系面临压力,特别是对环境和动物健康的影响,以及全球日益增长的蛋白质需求。在这方面,养殖肉类目前是工业界的热门话题,政治,和社会领域,揭示自己是上述问题的潜在缓解。然而,其高度的新颖性可能会阻碍消费者的接受程度。这项研究评估了关于内在属性和正外部性的信念,提供信息是影响意大利消费者小组对培养肉的感知和接受的足够工具。感知和尝试意愿的变化,购买,结果表明,感知受到有关安全和营养特征的积极信息的影响,而关于产品风味则相反。此外,调查结果显示,而在提供积极信息后,购买意愿增加,尝试的意愿没有。最后,关于培养肉的内在属性和正外部性的信息必须与不同的方法相结合,以进一步增强消费者的感知和接受度。
    The global meat production system is currently under pressure, particularly for its environmental and animal wellbeing impacts, as well as for the increasing protein demand worldwide. In this regard, cultured meat is currently a hot topic in the industrial, political, and societal arenas, revealing itself as the potential relief for the issues above. However, its high degree of novelty may hamper the extent of consumers\' acceptance. This research assesses for which beliefs concerning intrinsic attributes and positive externalities, the provision of information is a sufficient tool for affecting the perception and acceptance of cultured meat on a panel of Italian consumers. Changes in perception and willingness to try, buy, and pay are assessed by measuring the variation before and after the provision of positive information related to the product. The results show that perception is affected by positive information concerning safety and nutritional characteristics, whereas the opposite occurs regarding the product flavor. Furthermore, findings reveal that, while the willingness to buy increases after providing positive information, the willingness to try does not. Finally, information on intrinsic attributes and positive externalities of the cultured meat would have to be combined with different approaches for further enhancement of consumers\' perception and acceptance.
