采用模糊综合评判结合响应面法优化苹果酒发酵工艺参数,并用顶空固相微萃取气质联用(HS-SPME/GC-MS)技术分析其香气成分。以红富士苹果为原料,结合单因素试验结果,选取了酵母接种量、初始糖度、初始pH值三个主要工艺参数,采用中心组合试验设计,以苹果酒品质的模糊评判结果为目标,构建主因素突出型综合评判模型,进行响应面法分析。得到苹果酒最佳发酵工艺条件为:初始糖度19 g/100 mL,初始pH值3.5,接种量10%,发酵温度22 ℃。此条件下的苹果酒颜色金黄,酒体澄清有光泽,口感丰满协调、风格良好。苹果酒中共检测到33种香气成分,结合气味活性值(OAV)法鉴定出10种关键香气组分,这些香气物质构成了苹果酒的独特的风味。 相似文献

以‘金世纪’单一苹果品种及‘金世纪’、‘嘎啦’、‘澳洲青苹’混合(1∶1∶1)苹果品种为原料酿造苹果酒,并对其进行理化指标、多酚物质、香气成分测定及感官品评。结果表明,两种苹果酒理化指标差异不显著(P>0.05);混合发酵苹果酒中的酚类物质总量(61.88 mg/L)显著高于单独发酵苹果酒(56.90 mg/L)(P<0.05),其中以原儿茶酸、儿茶素、原花青素、表儿茶素和绿原酸为主。香气主要以醇类和酯类物质为主,两种苹果酒中醇类物质含量分别为216.83 mg/L和78.85 mg/L;酯类以乙酸乙酯、乙酸丙酯、乳酸乙酯和乙酸己酯为主,前三者在混合发酵苹果酒中含量均显著高于单独发酵苹果酒(P<0.05),使其香气更加浓郁和复杂。混合发酵苹果酒在澄清度、回味、香气、风味平衡方面更好,但在色泽方面稍差。因此,混合苹果品种发酵更适合于苹果酒的酿造。 相似文献

Aroma components play an important role in the quality of cider. To understand the contribution of every component to cider aroma quality, major aroma components present in ten ciders processed with different technological methods with different yeasts and apple orchards were determined by Headspace-solid phase microextraction–gas chromatography–mass spectrometry and internal standard method. Experimental results by principal component analysis indicated that ethyl acetate, acetic acid isobutylester, isopentylacohol acetate, ethyl caprylate, ethyl 4-hydroxybutanoate, isopentylalcohol, 3,4,5-trimethyl-4-heptanol, nonyl alcohol, 3-methylthio-1-propanol serve as the key aroma components in cider from Shaanxi (China) fuji apple. A model was established and verified for evaluating aroma quality based on factor analysis by comparing with the sensory evaluation method. 相似文献

Cross‐modal influence of colour from product and packaging alters perceived flavour of cider 下载免费PDF全文
With recent and rapidly growing consumer demand for alcoholic apple cider, markets have responded to provide for this demand. However, unlike the beer and wine industries, little consumer research exists to explore consumers' perception of cider. A large body of sensory research suggests that altering the colour of a food can significantly influence both perceived flavour of, and hedonic response to the food, despite there being no change to the food's taste or aroma qualities themselves. Our study was designed to understand how colour influences the perception of cider. A stock apple cider was subtly coloured red or green, and presented to consumers to evaluate hedonic response and for perception of flavour attributes. Following this, a cider identical to the control cider was presented with one of two labels, each featuring red or green prominently. Both the colour of the cider itself and the colour of the label significantly influenced perceived flavour and hedonic response to the ciders. Specifically, cider coloured green was perceived as being served at a colder temperature than the control, and the red sample showed an increase in perceived body. Red labelling of the cider made it seem both sweeter and fruitier. This study adds to the body of literature on multisensory perception of flavours, and may have significance for the cider industry's strategies for formulation and marketing.

在苹果酒发酵过程中,酿酒酵母会对各种胁迫和环境变化做出代谢应答。绿原酸是苹果和苹果酒中含量相对较高的一种苹果多酚类物质。本文以绿原酸为代表性苹果多酚,考察不同质量浓度的绿原酸胁迫对酿酒酵母生理特性的影响。结果表明:酿酒酵母CICC 31084在绿原酸胁迫下,主要通过改变胞内超氧化物歧化酶(SOD)活性、过氧化氢酶(CAT)活性和胞内丙二醛(MDA)含量来提高酿酒酵母的抗逆能力。其中,SOD活性随着绿原酸质量浓度的升高而逐渐增强;低质量浓度绿原酸(0.01 g/L)胁迫促使酿酒酵母的CAT活性增强;绿原酸胁迫降低了发酵前期MDA的含量,发酵后期MDA的含量增加。苹果酒中关键香气物质的质量浓度随发酵时间的延长逐渐升高,在发酵中期达到最大值后逐渐降低。相关性分析表明,关键香气物质苯乙醇、乙酸苯乙醇、癸酸乙酯、乙酸异戊酯的质量浓度与绿原酸质量浓度成正相关关系,相关系数分别为0.133,0.253,0.026,0.114;辛酸乙酯、正己酸乙酯的质量浓度与绿原酸质量浓度呈负相关关系,相关系数分别为-0.012,-0.248。 相似文献

Increasing concern about food safety following contamination of unpasteurized apple cider with Escherichia coli O157:H7 reinforces the need for using the best technologies in apple cider production. Pasteurization of apple cider with ultraviolet irradiation (UV) is a low‐cost alternative to heat pasteurization for small processing operations. UV treatment efficacy applied to raw unpasteurized apple cider was examined through evaluation of physical parameters, exposure time and treatment dosage. A UV light processing system was used to treat apple cider. The apple cider received a calculated average dosage of 8777 µW‐s/cm 2 per pass through the system. UV light (at 254.7 nm) was effective in reducing bacteria‐inoculated apple cider by an average of 2.20 logs per pass. In multiple passes, the 5‐log reduction mandated by the Food and Drug Administration was achieved. Sensory analysis yielded no significant differences between the UV‐treated and control apple ciders. Experiments with UV‐treated apple cider indicated a significant extension of product shelf life through inhibition of yeast and mold growth. For low throughput apple cider processing operations, this technology is a viable cost‐effective alternative. 相似文献
