Cold and fresh meat packaging, according to many domestic and international food science research, red meat is mostly adapted to O2=80%, CO2=20%. Under this environment, full myoglobin can be produced inside and outside red meat to maintain meat quality. Bright, while CO2 can destroy the bacterial growth environment. Extend the fresh-keeping period of cold meat to achieve the effect of cold and fresh meat.
Then, the chilled meat gas packaging machine puts strict requirements on:
1 Replace the air conditioning in the box (bag), and do not leave the original natural air as much as possible. In order to achieve a stable ratio of fresh gas. We use the amount of residual oxygen to indicate the cleanliness of the replacement. This is the basic premise of the preservation effect
2 Fill in a stable proportion of fresh gas. The fresh-keeping period fluctuates with the fluctuation of the proportion of fresh-keeping gas, so the ratio of fresh-keeping gas needs to have stable accuracy.
3 equipment stability, due to the production process, it is impossible to monitor the filling of the gas at any time, often due to equipment instability, resulting in fluctuations in the freshness cycle, and will bring losses.
At present, in the country, equipment manufacturers are uneven, shoddy, and even take nitrogen-filled packaging to deceive consumers. Need to remember the following points
1. Replace the air-conditioning packaging machine with the vacuum generator by the vacuum generator method, try not to adopt it, because the air in the package cannot be replaced and the stability is poor.
2. The use of gas flow meters or proportional valves to control the proportion of fresh gas, there will be instability of the preservation cycle
3. The process of making a modified atmosphere packaging machine is the key to the stability of the equipment.
In addition, a good slitting process not only has an aesthetic effect, but also reduces losses and improves efficiency. After the slitting is completed, the packaging is completed uniformly, which can provide continuous packaging for the later packaging, which can also improve the efficiency.
The freshness preservation cycle at different ratios may fluctuate greatly, so it is necessary to accurately and stably keep the proportion of fresh-keeping gas of the same kind of food. In order to ensure the consistency of the food preservation cycle. Another basic condition of the modified atmosphere preservation technology is that all foods can be placed in the cold chain to achieve the effect.
His range of applications: can be widely used in the packaging of baked goods such as meat, poultry, fish and fruits and vegetables, fresh food, cooked meat products, bread and cakes. Foods that have been packaged in modified atmosphere have become more and more popular among food processors and consumers because they maintain the original taste, color, shape and nutrition of the food and achieve a long shelf life.
Nowadays, whether it is in the fresh counters of large and small supermarkets or the packaging of various catering outlets, the packaging box of food is more and more beautiful, novel, and the preservation of the food itself is still very good, which is the use of modified atmosphere packaging machine technology. It has changed some of the ailments caused by simple packaging in the past.
