Kinjirushi’s quality check extended to ingredients

1. Ingredients inspection

Ingredient inspection

The inspector removes wasabi ingredients sent from production farmers, checks if there is any problem with color or condition and whether it is a safe ingredient not contaminated with microorganisms. In the case where ingredients are judged to have quality problems, the arrival is immediately stopped and a trace system assesses whether there is any possibility that ingredients with other problems are received.

2. Factory sanitation and question inspections

Factory sanitation and question inspections

Several check items for delivering safe products are done everyday by an inspector of sanitation, such as whether the interior of the factory is kept clean, if dirt is not adhering to the manufacturing machine, or whether workers at the site correctly handle the product. In addition, products in the manufacturing process are inspected in the adjacent quality inspection room, and when the state is different from usual, the staff of the quality control department take an order to quickly investigate the cause and solve the problem.

3. Shipment inspection

Only products that have cleared the inspection items performed in all processes from the ingredient arrival up to the final product are shipped. In addition, an inspection is done to check whether quality is kept within the use range, such as the expiration date specified in each product and storage method, and whether the quality changes even when it exceeds the range of the storage method.

Strictly set ingredients quality standards

In order to produce high quality and delicious wasabi products, Kinjirushi has established strict ingredients quality standards.

  • Ingredient that passed quality standards

Traceability system

We operate a traceability system in order to instantly investigate the cause and take measures in the case where a problem occurs. This system provides a system to quickly grasp the ingredients cultivation information, the usage status of auxiliary ingredients and food additives, and storage to distribution process, as well as to ensure safety.

The quality control department monitors all processes from wasabi cultivation to sales. Check items can be broadly divided into "cultivation method", "pesticide to be used", "fragrance" and "standard". We visit each production place and perform unannounced checks on cultivation and pesticide used, such as "Are you cultivating in a determined way?", "Are you using defined agricultural chemicals?". In addition, the fragrance of the wasabi ingredients is inspected by gas chromatography according to the standard, and the shape and freshness are visually confirmed.
Since wasabi is handled the same as fresh foods, it is a very delicate ingredient that can not be sterilized by heating, so thorough storage and transport management are necessary. After harvesting, it is important to process wasabi as quick as possible. In households, room-temperature type tube wasabi is the norm, but if you do not recognize that wasabi is a vegetable, genuine fragrance or pungent cannot be delivered.
