Description

A packaging technology for porridge

technical field

The invention relates to the technical field of food packaging, in particular to a porridge packaging technology.

Background technique

In industrial production, food additives such as thickeners, stabilizers, antioxidants and preservatives are often used to ensure porridge in a soft state, attractive color and long shelf life. The use of food additives can not only improve porridge The sensory quality of the porridge can also maintain a good state for a long time, and the cost is low, which is beneficial to long-term large-scale production; People's health is becoming more and more important. Consumers start to pay attention to food ingredients instead of taste when purchasing food. People are more inclined and advocating natural food.

Therefore, there is a need for an additive-free porridge with good food quality and natural taste in the market. According to the principle of modified atmosphere packaging, vacuum packaging technology is used to replace the air in the bowl with inert gas, which can better maintain the original food quality. The taste and color can avoid the use of food additives to a certain extent, and also achieve good shape and long preservation time.

Contents of the invention

The present invention makes improvements to the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the present invention is to provide a packaging technology that does not add any food additives and can ensure the mouthfeel and color of the porridge.

In order to solve the above problems, the present invention provides the following technical solutions:

A kind of packing technology of porridge, the packing technology of described porridge comprises the following steps:

1) Put the raw materials into the sterilized PP plastic container through the automatic filling machine, and then inject the prepared material liquid into the plastic container;

2) Send the filled plastic container into the modified atmosphere packaging machine for vacuuming, then fill it with inert gas, and seal the plastic container filled with inert gas with a sealing film;

3) Put the sealed plastic container into the sterilizer for sterilization.

Further, the plastic container is a plastic bowl with a cover.

Further, the temperature of the feed liquid injected into the plastic bowl is 70±1°C.

Further, the inert gas charged into the plastic bowl is nitrogen or a mixed gas composed of nitrogen and carbon dioxide.

Furthermore, the volume ratio of carbon dioxide in the mixed gas composed of nitrogen and carbon dioxide is not more than 50%.

Further, the sealing film is made of high barrier PP material.

Beneficial effects: the present invention fills the plastic bowl with inert gas by means of modified atmosphere packaging without using any chemical additives, prolongs the storage life of the porridge, and at the same time ensures the natural taste and color of the porridge to the greatest extent.

Detailed ways

Below in conjunction with accompanying drawing and embodiment of description, the specific embodiment of the present invention is described in further detail:

Specific embodiment one:

With reference to the packaging technology of a kind of porridge shown in Fig. 1, the packaging technology of described porridge comprises the following steps:

1) Put the raw materials into the sterilized PP plastic bowl through the automatic filling machine, and then inject the prepared material liquid with a temperature of 70±1°C into the plastic bowl;

2) Send the filled plastic bowl into the modified atmosphere packaging machine for vacuuming, then fill it with nitrogen, and seal the plastic bowl filled with inert gas with a high-barrier PP sealing film;

3) Put the sealed plastic bowl into the sterilizer for sterilization.

Specific embodiment two:

With reference to the packaging technology of a kind of porridge shown in Fig. 1, the packaging technology of described porridge comprises the following steps:

1) Put the raw materials into the sterilized PP plastic bowl through the automatic filling machine, and then inject the prepared material liquid with a temperature of 70±1°C into the plastic bowl;

2) Send the filled plastic bowl into the modified atmosphere packaging machine for vacuuming, then fill it with a mixed gas composed of nitrogen and carbon dioxide, wherein the volume ratio of nitrogen gas is 70%, and the volume ratio of carbon dioxide is 30%, and use The high-barrier PP sealing film seals the plastic bowl filled with inert gas;

3) Put the sealed plastic bowl into the sterilizer for sterilization.

Specific embodiment three:

With reference to the packaging technology of a kind of porridge shown in Fig. 1, the packaging technology of described porridge comprises the following steps:

1) Put the raw materials into the sterilized plastic bowl through the automatic filling machine, and then inject the prepared material liquid with a temperature of 70±1°C into the plastic bowl;

2) Send the filled plastic bowl into the modified atmosphere packaging machine for vacuuming, then fill it with a mixed gas composed of nitrogen and carbon dioxide, wherein the volume ratio of nitrogen gas is 50%, and the volume ratio of carbon dioxide is 50%, and use The high-barrier PP sealing film seals the plastic bowl filled with inert gas;

3) Send the sealed material bowl into the sterilizer for sterilization.

The invention has been repeatedly verified by theory and practice. Before sealing, the technology of vacuuming and filling inert gas is adopted. The sealing film used is a sealing film with high barrier performance, which can convert the air in the package and create a microscopic environment suitable for long-term storage for the porridge. The environment ensures the natural taste and color of the porridge to the greatest extent, and achieves the purpose of air-conditioning preservation and long-term preservation. Among them, in order to ensure that all the air in the bowl is evacuated, the time for vacuuming is 10-15 seconds, and the time for filling inert gas is also 10-15 seconds.

The above description is only a preferred embodiment of the present invention, and does not make any limitation to the technical scope of the present invention, so any minor modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention are still valid. It belongs to the scope of the technical solution of the present invention.
