Latest company news about Introduction of raw material selection for fruit processing production line

The requirements for the cleanliness of fruit juice processing raw materials in fruit processing production lines mainly refer to the initial bacterial content and pesticide residues on the surface and interior of fruit raw materials. In the juice processing raw material dirt, the dirt contains a large number of microorganisms, some raw materials are mixed with leaves, small tree sap or packaging materials, some fruits are damaged or the surface of the fruit is covered with dirt. It is prone to rapid decay during storage, so cleaning and removing impurities is a very important process. The more important factor in determining the storage performance of a juice processing material is the initial bacterial content of the material at the time of purchase. The content of bacteria also determines the effect and duration of preservation (sterilization), thus ensuring the quality of the juice. At present, countries around the world have very strict requirements on pesticide residues in fruit juice. In particular, some special foods are not allowed to contain pesticide residues, such as baby food and health food.
The entire way to limit pesticide residues in fruit and vegetable raw materials in fruit processing production lines is for fruit and vegetable juice manufacturers to sign contracts with fruit and vegetable raw material suppliers to ensure that they can effectively monitor all planting methods of fruit and vegetable raw materials suppliers, so that the pesticide residues in fruit and vegetable raw materials do not exceed the contract. the specified higher limit. When implementing the contract, the fruit juice production enterprise shall only allow the raw material suppliers to use the inspected, nationally standardized and specified concentration of plant protection agents. When using these pesticides, the time interval should be pre-set. Prevent fruit pests and diseases early (winter spray and growing leaves). After the leaves grow, targeted spraying should be carried out in combination with biological control measures, rather than general spraying, and if possible, no spraying at all. At the same time, fruit juice enterprises should strive to improve the cleanliness of fruit juice processing raw materials and improve the cleanliness of fruit juice processing raw materials.
Juice raw materials that have been spoiled or have begun to spoil in the fruit processing production line cannot be used to make juice; if many juice processing raw materials in the raw material storage warehouse have been seriously spoiled, it is not enough to remove the spoiled fruit. At this point, the taste and smell substances of the rotting fruit have entered the interior of the healthy fruit. Generally speaking, juice raw materials stacked in storage spaces have lost their processing value. Therefore, juice raw materials invaded by various spoilage fungi and insect larvae are damaged. Regardless of the provisions of the Food Sanitation Law or the interests of consumers, juices made from these raw materials are unsanitary and of poor sensory quality, and cannot be used as raw materials for juice processing. If the juice processing material is damaged due to non-parasitic effects, such as the impact during picking and transportation, or damage caused by hail or freezing, the juice processing material should be treated immediately once injured, otherwise it cannot be used.
Generally speaking, the reasons for the deterioration of fruits can be divided into three categories: one is mechanical damage caused by bumping; the other is injury caused by low temperature; the third is mildew and rot caused by microbial infection. Guofeng believes that the selection of fresh fruits is not only to maintain the good reputation of the enterprise, but also to maintain the trust between people.
