Description

This invention relates to an apparatus for shelling eggs, particularly an apparatus for obtaining a mixed product, namely a mixed product of egg yolk and egg white, or an apparatus for obtaining egg yolk and egg white separately, wherein the shelled product can be obtained with a longer shelf life compared to prior art solutions, provided that other processing conditions are equal. In the field of food processing, there is a strong need to both achieve a long shelf life and produce products with sensory characteristics similar to those of fresh produce. In the field of egg processing, extended shelf life is achieved by adjusting pasteurization parameters. In other words, a product to be pasteurized, whether it is a mixture of egg yolk and egg white or pure egg white, is brought into contact with a high-temperature surface, from which it receives pasteurization heat. The pasteurization temperature must be maintained substantially within the range of 57°C to 72°C, depending on the product being pasteurized, in order to avoid degrading the product at a high temperature or to avoid obtaining insufficient pasteurization at a low temperature. The purpose of pasteurization is to reduce the bacterial load present in the product being pasteurized. Therefore, along with the temperature, the main parameters of the pasteurization process are the duration of the isothermal period, i.e., the duration for which the product is maintained at the pasteurization temperature. Within the temperature limits mentioned above, longer isothermal periods determine a greater reduction in the bacterial load; therefore, depending on the intended use of the final product, higher pasteurization temperatures may be selected and combined with shorter isothermal periods, or conversely, longer isothermal periods may be combined with lower temperatures. The pasteurization temperature and relative isothermal period are determined according to the bacterial load contained in the product to be pasteurized. Higher temperatures combined with shorter isothermal periods are beneficial for productivity, while lower pasteurization temperatures and longer isothermal periods are advantageous for the sensory quality of the resulting product. Generally, the sensory quality of the resulting product improves as the thermal pasteurization treatment is less stringent; that is, as the temperature is lower and the isothermal period is shorter.
