速冻水饺是目前冷冻面制品中最为普遍的一种,近几年来市场逐渐发展,成为速冻食品行业中的主流产品。但在实际生产过程中,速冻水饺经常会出现抗冻能力低、耐蒸煮性差等弊端,对水饺质量造成影响。其中主要因素包括馅料性质、产品加工以及原材料性质等等,在速冻过程中,面团质量特征会发生劣变,导致冷藏质量差。因此,选择合适的品质改良剂,对面团在速冻、冷藏直到运输、解冻等过程中的品质有积极作用。以下将选取几种常用的品质改良剂,对采用不同品质改良剂水饺的冻裂率、耐煮性以及韧性进行分析,筛选出合适的品质改良剂,为速冻水饺生产提供依据。 相似文献

Prior investigations have indicated that relationships between price and product quality are considerably weaker for non-durables than for durables. Among non-durables, packaged food products frequently have exhibited the poorest correspondence between price and quality. This study, utilizing data from Consumers Union, analyzes the relationships between price and a measure of product quality for 679 brands in forty packaged food product classes over a fifteen year period. The study generally confirms earlier preliminary conclusions that the correlation between quality and price for packaged food products is near zero. In addition, the findings indicate that convenience foods, particularly frozen foods, display the poorest correspondence between price and product quality with more than 43 percent of all frozen food product classes exhibiting negative relationships between price and product quality. Some possible explanations for these findings and their implications for public policy are advanced. 相似文献

葡萄酒具有很高的营养价值,能够满足人们对于美容养颜功效的追求。葡萄酒中的白藜芦醇还具有独特功效,不仅能够帮助人体抗癌、抑制肿瘤,还能够帮助消费者抗动脉粥样硬化和冠心病。其中,白藜芦醇(C14H12O3)是由碳、氢、氧3种元素组成的,它的相对分子质量为228,随着葡萄酒发酵时间的改变,其白藜芦醇的含量会发生变化,而酒的品质也会发生改变。控制葡萄酒的合理发酵时间,有利于提高葡萄酒的品质。 相似文献

The same (chilled) food product was presented to 77 consumers with either a frozen or chilled label. As predicted, liking for the food product was found to be in line with consumer expectation of liking for the different preservation format labels. For example, consumers that expected chilled foods to taste better than frozen reported higher liking for the product with the chilled label, even though actual quality of all products tasted was the same. Contrary to our prediction that tasting similar quality products perceived to be from different preservation formats would bring expectation of liking for those formats closer together, we found consumers who expressed no preference before tasting the products had developed a preference afterwards. We discuss the implication of these results and similarities between the concepts of conditioning, attitude, expectation and preference. 相似文献

The 2002 Farm Securit and Rural Investment Act mandated that country-of-origin labeling (COOL) be applied to specific food commodities. Using revealed preference data for 1998–2006, a nonlinear AIDS model is used to estimate the demand for uncooked frozen, uncooked fresh, and precooked salmon to assess the impact of the legislation on consumer demand patterns. Findings from a non parametric analysis suggest a possible rotation in the demand curve for fresh salmon that may be linked with the quality signal associated with COOL. However, our findings indicate that COOL had no significant impact on overall consumer demand for the three products. All three were found to be inelastic, with uncooked fresh salmon being slightly more price sensitive than uncooked frozen and precooked salmon. Given the expenditure elasticities, the fresh salmon segment of the industry appear to be more vibrant than the other salmon segments and would likely influence investment decisions in the salmon industry. 相似文献
