Frozen Flat Green Beans

High-quality raw material procurement:
Selecting high-quality green beans is the basis for ensuring product quality. Purchase from reputable suppliers who can provide green beans that meet quality and safety requirements. For example, the supplier's planting base should adopt good agricultural practices (GAP), including the rational use of pesticides and fertilizers, to ensure soil quality and the safety of irrigation water.
Strict inspection of raw materials is an essential link. When purchasing, check the basic indicators of green beans such as appearance, size, and freshness, and also test items such as pesticide residues and heavy metal content. Professional testing equipment can be used, such as gas chromatography-mass spectrometry (GC-MS) to detect pesticide residues and atomic absorption spectrometers to detect heavy metal content.
Traceability system establishment:
Establish a complete raw material traceability system to record information such as the source, planting process, fertilization and medication of green beans from the planting stage. In this way, when there is a quality problem with the product, the source of the problem can be quickly traced back and corresponding measures can be taken. For example, by assigning a unique identification code to each batch of raw materials, information such as its growing farm, picking date, and transportation route can be recorded.

During the production and processing process, we strictly follow the good manufacturing practice. This includes keeping the production workshop clean and hygienic, cleaning and maintaining the equipment regularly, and preventing cross contamination. For example, the floor, walls and equipment surfaces of the processing workshop should be easy to clean and disinfect, and the processing personnel should wear work clothes, masks and gloves that meet hygiene standards.
Strictly control key parameters such as temperature and time in the production process. For frozen green beans, the temperature and speed of the quick freezing process have a great impact on product quality. Generally speaking, the quick freezing temperature should be lower than - 30℃ to ensure that the green beans pass through the ice crystal formation zone quickly, reduce the damage of ice crystals to cells, and maintain the taste and nutritional content of the product.
Establishment of quality inspection system:
Establish a complete quality inspection system, including online inspection during the production process and final inspection of finished products. Online inspection can promptly detect quality problems in the production process, such as detecting whether there are metal foreign bodies mixed in the product through a metal detector. Finished product inspection is to comprehensively check whether the product meets the quality standards of the target market. The inspection items include pesticide residues, heavy metals, microorganisms, sensory indicators, etc.
We regularly conduct internal audits and management reviews of our quality testing system to ensure its effectiveness and reliability. At the same time, we also participate in the proficiency testing activities of external laboratories, compare with other laboratories, and improve our own testing capabilities.
