This study develops low-fat microwaved peanut snacks(LMPS)using partially defatted peanuts(PDP)with different defatting ratios,catering to people’s pursuit of healthy,low-fat cuisine.The effects of defatting treatment on the structural characteristics,texture,color,and nutrient composition of LMPS were comprehensively explored.The structural characteristics of LMPS were characterized using X-ray micro-computed tomography(Micro-CT)and scanning electron microscope(SEM).The results demonstrated that the porosity,pore number,pore volume,brightness,brittleness,protein content,and total sugar content of LMPS all significantly increased(P<0.05)with the increase in the defatting ratio.At the micro level,porous structure,cell wall rupture,and loss of intracellular material could be observed in LMPS after defatting treatments.LMPS made from PDP with a defatting ratio of 64.44%had the highest internal pore structural parameters(porosity 59%,pore number 85.3×105,pore volume 68.23 mm3),the brightest color(L*78.39±0.39),the best brittleness(3.64±0.21)mm^(–1)),and the best nutrition(high protein content,(34.02±0.38)%;high total sugar content,(17.45±0.59)%;low-fat content,(27.58±0.85)%).The study provides a theoretical basis for the quality improvement of LMPS.

以湘派卤制品卤汁为研究对象,对其贮存过程中产黄曲霉毒素的微生物(产毒菌)进行筛选鉴定并对产毒能力进行测定。采用平板稀释涂布法和紫外荧光法对湘派卤汁进行产毒菌的初筛;对初筛菌株的ITS序列进行PCR扩增、测序,测序结果经NCBI同源性对比、MEGA6.0软件构建系统发育树进行分子生物学鉴定;应用HPLC-MS/MS检测各产毒菌培养液中黄曲霉毒素(aflatoxin,AFs)含量,确定各产毒菌的产毒能力。经平板稀释涂布法、紫外荧光法和分子生物学共筛选鉴定出5株产毒菌株,其中有4株是黄曲霉(Aspergillus flavus),1株为寄生曲霉(Aspergillus parasiticus);经HPLC-MS/MS法确定4株黄曲霉均不产生AFs,寄生曲霉产生黄曲霉毒素B 1(AFB 1)和黄曲霉毒素G 1(AFG 1)。AFB 1在第3天和第7天的含量分别为6.92、8.08μg/L,AFG 1在第3天和第7天的含量分别为5.80、7.24μg/L;湘派卤汁由于贮存条件不当,易受霉变原辅料及环境的影响,存在产AFs的曲霉菌,警示湘派卤制品卤汁中存在AFs污染的安全风险问题。

Tobacco(Nicotiana tabacum)and tomato(Solanum lycopersicum)are two major economic crops in China.Tobacco mosaic virus(TMV;genus Tobamovirus)is the most prevalent virus infecting both crops.Currently,some widely cultivated tobacco and tomato cultivars are susceptible to TMV and there is no effective strategy to control this virus.Cross-protection can be a safe and environmentally friendly strategy to prevent viral diseases.However,stable attenuated TMV mutants are scarce.In this study,we found that the substitutions in the replicase p126,arginine at position 196(R196)with aspartic acid(D),glutamic acid at position 614(E614)with glycine(G),serine at position 643(S643)with phenylalanine(F),or D at position 730(D730)with S,significantly reduced the virulence and replication of TMV.However,only the mutation of S643 to F reduced the RNA silencing suppression activity of TMV p126.A double-mutant TMV-E614G-S643F induced no visible symptom and was genetically stable through six successive passages in tobacco plants.Furthermore,our results showed that TMV-E614G-S643F double-mutant could provide effective protection against the wild-type TMV infection in tobacco and tomato plants.This study reports a promising mild mutant for cross-protection to control TMV in tobacco and tomato plants.

近年来,微创青光眼手术(MIGS)在降低眼压和减少术后并发症中显示出良好的前景。XEN凝胶引流装置植入术作为一种新型的MIGS,在材料特质、房水引流功能以及降眼压机制等方面展现出区别于其他青光眼引流阀装置的独特优势。XEN凝胶引流装置植入术与传统的复式小梁切除术在降低眼压、减少药物使用数量等方面的治疗结果类似,但XEN凝胶引流装置植入术的术后并发症相对较少,安全性更高。因此,XEN凝胶引流装置植入术可能是难治性青光眼持续性高眼压的一种治疗方案。

2019年颁布的《关于建立健全可再生能源电力消纳保障机制的通知》标志着我国可再生能源消纳进入强制考核时代,建立绿色电力证书(简称"绿证")交易市场十分必要。针对各省面临的可再生能源消纳任务,设计了国家绿证交易市场和省级日前电力市场协调均衡机制。针对发电侧可再生能源电厂间的差异性,创新性建立了基于熵权法的绿证核发评价体系用以指导可再生能源的绿证核发;从消纳考核要求出发,构建了省级日前电力市场出清模型与国家绿证交易市场出清模型,发电商和售电公司共同参与省级日前电力市场进行电量和绿证的直接交易;在国家绿证交易市场中,受到不同可再生能源消纳配额百分比的影响,售电公司通过竞价进行绿证的购买和售出;算例分析验证了所述机制的可行性和有效性。
