Description

本発明は、酸性乳化液状調味料に関し、より詳細には、少なくとも、食用油脂及び水を含有する酸性乳化液状調味料に関する。   The present invention relates to an acidic emulsified liquid seasoning, and more particularly to an acidic emulsified liquid seasoning containing at least edible oil and water and water.

従来、酸性乳化液状調味料の代表的製品としてマヨネーズやサラダドレッシング等が知られている。これらの中でも、油脂含有量が多い調味料は、油脂が酸化することによって保存中に風味が劣化することが知られている。油脂含有量が多く、かつ賞味期間の長いマヨネーズやサラダドレッシングのような酸性乳化液状調味料においては、酸化による風味劣化の抑制が重要な課題であった。酸化の抑制方法として、海外ではエチレンジアミン四酢酸(EDTA)を含有させることが多く行われているが、日本では食品衛生法により缶詰又は瓶詰食品以外での使用は認められていない。したがって、これらの調味料において、長期保存中にもより良好な品質を保つための手段が求められている。   Conventionally, mayonnaise, salad dressing and the like are known as representative products of acidic emulsified liquid seasonings. Among these, it is known that seasonings with a high fat content deteriorate in flavor during storage due to oxidation of the fat. In acidic emulsified liquid seasonings such as mayonnaise and salad dressings that have a high fat content and a long shelf life, suppression of flavor deterioration due to oxidation has been an important issue. As a method for suppressing oxidation, ethylenediaminetetraacetic acid (EDTA) is often contained overseas, but in Japan, use other than canned or bottled food is not permitted by the Food Sanitation Act. Therefore, in these seasonings, means for maintaining better quality during long-term storage is required.

上記の課題に対して、クロロフィル類の含有量が従来の植物油脂よりも低減され、さらに一定の範囲内とした大豆油を使用することにより、長期保存中にも風味の変化が少ない酸性調味料を提供することが提案されている(特許文献1参照)。   In response to the above problems, the use of soybean oil in which the content of chlorophylls is lower than that of conventional vegetable oils and within a certain range makes it possible to reduce the change in flavor even during long-term storage. Has been proposed (see Patent Document 1).

By controlling the temperature to 65 ° C. or lower, the heat denaturation of egg yolk protein can be suppressed, the viscosity is close to that of raw egg yolk, it can be easily mixed with other raw materials, and the production of an acidic emulsified liquid seasoning is facilitated. Moreover, the production | generation of an egg yolk lipid oxide can be suppressed and an astringent taste can be suppressed. The aging temperature is a temperature that is maintained substantially constant during the aging time described later, but may be increased and decreased within the above range. Further, by aging the mixture while heating at the above aging temperature, the temperature becomes the optimum temperature of the enzyme and the degradation rate can be improved, so that the aging period can be shortened. Furthermore, since the aging period is shortened, the amount of sodium chloride added can be reduced from the viewpoint of storage stability, so that it is possible to prevent umami and richness from being damaged by excessive saltiness.

(熟成時間)
熟成時間は、好ましくは24時間以上300時間以下であり、より好ましくは24時間以上240時間以下であり、さらに好ましくは48時間以上192時間以下である。熟成時間を上記範囲内とすることで、十分に熟成させて卵黄タンパク質を分解し、コク味を増すことができ、また、卵黄脂質酸化物の生成を抑制し、収斂味を抑えることができる。
