近年来,随着鱼类加工产量的增加,其加工产生的副产物也随之增多。鱼皮作为鱼类加工副产物之一,含有丰富的蛋白质、氨基酸、矿物质和不饱和脂肪酸等,具有较强的加工潜力,但目前能够将其进行加工的企业较少,通常是将鱼皮直接丢弃,这不仅造成大量的浪费,而且污染环境。本文梳理了鱼皮中的营养成分、胶原蛋白的提取方法以及已有的鱼皮加工制品,对鱼皮在食品、功能性产品、化妆品、医疗和服饰领域等不同方面的研究现状及应用概况进行综述,提出现阶段鱼皮加工应用领域中所存在的问题,并对未来鱼皮加工产品的走向和发展进行展望,以期为鱼类加工副产物的高值化利用提供参考依据,对优化和拓宽我国水产品副产物的研究领域和提升国家经济效益具有重要意义。 相似文献

目的:研究蓝莓花青素(BA)对罗非鱼鱼皮挥发性化合物的影响,揭示其脱腥机理。方法:采用不同质量浓度的蓝莓花青素处理罗非鱼鱼皮,通过电子鼻、GC-IMS、GC-MS等分析风味物质的变化。结果:0.03,0.06,0.12,0.24 mg/mL BA组鱼皮在表征风味物质的电子鼻传感器中,获得比空白组和对照组(0.06 mg/mL GA)较低的响应值,特征传感器W2S、W1W、W1S中空白组响应值分别为1.106,1.196,1.114,表明BA处理可有效减少鱼皮中的醇、醛、酮类、含硫化合物、芳香族化合物等物质。GC-IMS鉴定指纹图结果表明,经BA处理的鱼皮的挥发性物质与空白组存在差异。GC-MS定量结果再次验证鱼皮中的特征性风味化合物的含量及气味活性值受BA的影响,庚醛含量由159.16μg/kg减少到121.46μg/kg,辛醛含量由121.62μg/kg减少到99.90μg/kg,壬醛含量由445.57μg/kg减少到419.58μg/kg(P<0.05)等,BA处理使鱼皮中反式-2-壬烯醛的含量出现显著差异,0.03 mg/mL BA组含量为17.00μg/kg(P<0... 相似文献

斑点叉尾(鱼回)鱼皮明胶的风味成分及其脱腥的研究 总被引:1,自引:0,他引:1
采用顶空固相微萃取和气质联用技术,分析了斑点叉尾(鱼回)鱼皮明胶的风味成分,比较了活性炭、β-环糊精和酵母3种脱腥剂对明胶的脱腥效果。结果表明:斑点叉尾(鱼回)鱼皮明胶的风味成分主要是一些含有羰基的饱和或不饱和的醛类和酮类;(鱼回)鱼皮明胶腥味最为相关的成分为正己醛、正庚醛、2,4-庚二烯醛、2,6-壬二烯醛。活性炭、β-环糊精和酵母都有一定的脱腥效果,其中活性炭脱腥效果最好。活性炭脱腥前醛、酮种类个数分别为13和6,脱腥后减少为5和4;活性炭脱腥前醛、酮含量为27.89%,脱腥后降至10.92%。尤其与腥味相关的正己醛、正庚醛、2,4-庚二烯醛、2,6-壬二烯醛等成分在脱腥后,均未被检出。 相似文献

目的 研究添加黑线鳕鱼(Melanogrammusaeglefinus)皮对鱼糜凝胶特性和蛋白质结构的影响。方法以傅里叶变换红外光谱法和十二烷基硫酸钠-聚丙烯酰胺凝胶电泳技术的分析方法,探究黑线鳕鱼皮不同添加比率对鱼糜凝胶的凝胶强度、质构、持水性、p H和蛋白质分子组成及其二级结构的影响规律。结果 当鱼皮添加比率为5%时,混合凝胶的凝胶强度、弹性和持水性虽下降但无显著变化(P>0.05),分别为2654.4 g·mm、2.83 mm和85.7%,而硬度显著下降至22.83 N (P<0.05);随着鱼皮添加比率的增加,鱼糜凝胶的凝胶强度、质构、持水性均下降;鱼皮的添加阻碍了肌球蛋白重链发生交联,同时,鱼糜凝胶蛋白质结构无显著变化(P>0.05)。结论为提高鱼皮的利用率,可适量将鱼皮与鱼糜混合制备鱼糜凝胶,鱼皮添加比率不宜超过5%。 相似文献

Clinical and instrumental evaluation of a food supplement in improving skin hydration 总被引:1,自引:0,他引:1
Topically applied cosmetic products can be helpful in improving skin hydration. The study shows how oral supplementation could be helpful in improving and preventing the skin dehydration. A total of 32 healthy female volunteers entered the study. Of which, 16 were treated with a food supplement based on vegetable ceramides, amino acids, fish cartilage, antioxidants and essential fatty acids for 40 days and 16 with placebo. The results of the clinical and instrumental evaluations carried out in this study, have highlighted how the active treatment is effective in improving skin hydration and in reducing the cutaneous smoothness and roughness and the depth of furrows, in comparison to the placebo. In fact, concerning several important parameters, as stratum corneum hydration and skin roughness, the improvement measured exceeded 25%. We therefore suggest that a combination of treatments (oral and topical) can be more effective in improving skin hydration. 相似文献

The topically applied cosmetic products can be helpful in improving the aged skin condition. The present study shows how oral fish-cartilage food supplementation can be helpful in improving the treatment of ageing skin. A total of 30 healthy women with signs of skin ageing were studied. Fifteen of the women were treated with a food supplement based on polysaccharides derived from the fish cartilage and a natural mix of antioxidants for 2 months and the other 15 with a placebo. Clinical evaluation and biophysical parameters related to skin function and wrinkle severity, such as silicone replica, skin thickness, mechanical properties, skin colour and capacitance, were measured. The results showed statistically significant changes in the active-treated group in comparison to the placebo. In particular, dermal thickness (treatment: from 1.13 to 1.23 mm; P < 0.001), skin wrinkling (treatment: from 9.5 to 3.5 R(a); P< 0.002), skin colour (treatment: brighter and less pigmented; P < 0.02) and viscoelasticity (treatment: from 0.70 to 0.97%; P < 0.02) showed considerable improvement. Most of these parameters are related to changes occurring within the dermal matrix, which is improved after the treatment, whereas most of the topically applied cosmetic products have a short-term effect on superficial structures. A combination treatment (oral and topical) can be more effective in reducing the signs of skin-ageing. 相似文献

Gelatin was extracted from the skin of farmed giant catfish (GC) and tilapia (TP) at a yield of 19.50% and 23.34% (wet wt). It was high in protein (84–88%) but low in fat (0.09–1.24%) and ash content (0.15–0.17%). The GC exhibited lower emulsifying activity (24–35%), but greater foam ability (98–110%), water holding capacity (477–844%) and fat binding capacity (2541–3314%) than commercial beef skin gelatin (BF) (P < 0.05). GC and TP showed comparable functional properties to BF. SDS‐PAGE patterns of TP gelatin showed high band intensity for the α‐ and β‐components, while the lowest band intensity of the major component was found in the BF. From the study, it can be concluded that the farmed freshwater fish skin GC and TP is a prospective source for producing a significant gelatin yield with desirable functionalities. Because of these, fish skin gelatin could be more effectively and widely used in food industries as a good food ingredient. 相似文献
