为研究烤制鸽肉工艺便捷设计方法和确定关键工艺参数,采用烤制工艺制备烤制鸽肉,探究腌制时间、烘烤时间和烘烤温度对产品食用性状的影响,以回复性、弹性、硬度、咀嚼性、胶着性、内聚性及感官评分为食用性状评价指标,采用信息熵法确定各指标的熵权系数,计算出综合值,利用响应面法(response surface methodology, RSM)和反向传播(back propagation, BP)人工神经网络耦联遗传算法(genetic algorithm, GA)(BP-GA)进行参数优化及预测。结果表明,RSM得到最优工艺参数组合为腌制时间15.4 h、烘烤时间10 min、烘烤温度205℃,该法相对误差为2.54%;BP-GA神经网络得到最优工艺参数组合为腌制时间14 h、烘烤时间10 min、烘烤温度240℃,该模型相对误差为0.17%。BP-GA神经网络的相对误差小,拟合与优化性能好,且试验次数少,可容纳参数多。依托BP-GA神经网络优化的参数制作的烤制鸽肉综合值与RSM一致。该研究可为鸽肉加工工艺优化提供一定的参考。 相似文献

The effects of pre-salting methods on water distribution and protein denaturation of dry salted and rehydrated cod - A low-field NMR study 总被引:1,自引:0,他引:1
Low field Nuclear Magnetic Resonance (LF-NMR) relaxation time measurements were used to evaluate the effect of different pre-salting methods (brine injection of salt and/or phosphates followed by brining, solely brining, pickling and kench salting) on the protein denaturation and change in muscle properties during the production steps of dry salted cod fillets followed by rehydration. The NMR relaxation curves were affected by the salting method and represented well the structural differences between the salting methods at each processing step. Significant correlations were observed between the NMR relaxation parameters and all physicochemical quality properties measured, except the cooking yield, when samples from all processing stages were analyzed together. The longitudinal relaxation time T1, and the faster relaxing transverse relaxation time T21 were shown to be especially sensitive to protein denaturation in the fillets. The water distribution indicated that the salting and rehydration processes changed the cells irreversibly. The study indicated that pre-brining by brine injection followed by brining, with low salt concentrations, led to the least protein denaturation during the dry salting and rehydration process. 相似文献

为开发非油炸果蔬脆片产品,本文以黄桃为原料,采用流化-微波-烘焙相结合的生产工艺,以色差、Vc含量、感官评分和脆度等为评价指标,采用单因素实验和正交实验研究流化温度、流化风速、微波功率、微波时间、烘焙温度和时间等因素对黄桃脆片品质的影响,并分别对流化、微波和烘焙阶段进行工艺参数进行优化。试验结果表明:黄桃脆片的最佳生产工艺为流化温度55℃、流化风速300 m3/h;微波功率400 W、微波时间600 s,流化和微波转换时黄桃水分含量约20%;烘焙温度65℃、烘焙时间为35 min。在该工艺下研发的黄桃脆片口味甚佳,色泽较好,感官评分为91分,脆度值为469 g。该研究为非油炸果蔬脆片的加工提供了理论依据,也为果蔬类干制产品的开发拓宽了思路。 相似文献

Feta cheese was manufactured by using five different salting methods (dry salting for one day followed by addition of 6% NaCl brine, dry salting for 1,2 or 3 days followed by addition of 7% NaCl brine and dry salting for 3 days followed by addition of 8% NaCl brine). The effects of salting method and storage time on the composition, physicochemical, organoleptic and rheological properties of feta cheese were studied. It was found that moisture was not affected by salting method or storage time. The salting method but not the storage time had a significant effect on salt content. As the salt content of cheeses increased or the storage time was prolonged the moisture decreased. pH and cheese yield were not influenced by salting method but did decrease with storage time. Protein content was not affected by salting method or storage time, whereas fat content was affected by both factors. Proteolysis, lipolysis, organoleptic and rheological properties of cheeses were not influenced by the salting methods applied. On the other hand, storage time had a significant effect on proteolysis, lipolysis, cheese appearance, fracturability and percentage compression at the yield point. Dry salting of cheese for one day and preservation in 7% NaCl brine was considered as the most appropriate salting method for practical application. 相似文献

水焗法生产盐焗鸡工艺初探 总被引:2,自引:0,他引:2
文章以盐焗鸡感官评分和色差为指标,采用单因素和正交试验考察了水焗时间、烘制时间、烘制温度对成品的影响,并优化了水焗法加工工艺。研究结果表明:卤水焗制30min,在100℃下烘制12h效果最佳,成品香味较浓,保持了传统盐焗骨香味浓的特色。作为盐焗鸡生产三法之一,水焗法工艺简单、生产周期短,但成品特色不明显,需进一步改善。 相似文献
