Thorough Checks of Ingredient Specifications and Quality

As a fabless company, DyDo DRINCO subcontracts mass production to external plants, while product concepts, recipes, and other planning and development tasks are conducted in-house. To ensure the products that reach our customers are safe and reliable in addition to being tasty, we prioritize maintaining a dependable quality assurance and management framework. Starting at the phase of product planning, we apply attention to checking the ingredient and quality specification sheets provided by suppliers for each ingredient that will be used in a product. In addition to confirming that legal requirements are met for all ingredients and furthermore we review safety-related information such as residual agricultural chemicals or allergens.

Pre-evaluation meetings at product planning stage
  • Quality Control Section
  • Product Dvelopment Section
Reviews of composition, labeling, and product design.
  • Check via ingredient specification sheet
    Review of details including ingredient manufacture, country of production, blending ratio, allergen presence, GMO presence, presence of beef- or pork-derived ingredients
  • Check via quality specification sheet (statement of quality assurance)
    Quality standards, manufacturing processes, handling conditions, safety according to Food Sanitation Act,* checking for the presence of residual agricultural chemicals
Only safe ingredients that meet legal requirements are used in products

* The Food Sanitation Act is a Japanese law established to set standards for foodstuffs to prevent sanitation hazards resulting from ingestion of food or drink, including additives used to protect people from toxic and harmful substances or bacteria.

Visits to Production Regions and Processing Plants

We establish strict standards for ingredients at the product planning stage and then procure those ingredients only from suppliers that clear those standards. For major imported ingredients our managers visit and check in person on growing conditions of agricultural products at farms, and manufacturing processes, hygiene management, and other aspects at processing plants. We also work to assure safety and improve the quality of ingredients by communicating the results of our visits directly to our business partners.

A Double-Check System for Products

DyDo DRINCO has established a system of double checks as a fabless company that subcontracts manufacturing to affiliate plants. We work with affiliate plants on ensuring a rigorous management and inspection system to constantly maintain safe and reliable manufacturing and distribution.
Safety and reliability are not achievable by individuals working alone. It is achieved by using an organization-wide system that emphasizes keeping safety in mind at all times and involves daily quality control efforts based on the methodologies of 5S (seiri, seiton, seiso, seiketsu, and shukan [sort, organize, clean, maintain, and discipline ]) and 5W1H (who, what, where, when, why, how).

Checks at Each Affiliate Plant

Based on quality control standards at the respective affiliate plant, various tests are conducted—tests for each process, post-manufacturing product inspection, constant temperature testing, bacteriological testing, etc.

  • Control panel
  • Monitoring panel
  • Sensory evaluation
  • Monitoring room

DyDo DRINCO Checks

Product samples and inspection check sheets from each affiliate plant are verified, amongst other measures.

  • Component analysis data screen
  • Component extractor
  • Sensory evaluation
  • Quantitatice analysis check of tannins, caffeine, etc.
  • High-speed liquid chromatography (HPLC)

Production Control Department,

We always try to see things from the customer's perspective and supply products that we would recommend to our own families with confidence. Prior to a product's release we thoroughly investigate any areas of risk with regard to product labeling or ingredients to guarantee the product's safety.
We also check that no operational problems are encountered with a product at the manufacturing plant, and do not rely solely upon the plant's assessment. Before shipping, we always conduct a visual examination of the product and labeling, check the product's characteristics and physical properties, and perform a sensory evaluation to ensure there are no problems.
We aim to assure the safety of products and further improve quality from the customer's perspective so that DyDo products are liked by one and all.

Quality Assurance Audits at Affiliate Plants

DyDo DRINCO conducts annual quality assurance audits at the affiliated plants to which it outsources production. We ask plants to self-assess a quality assurance audit check sheet that features more than 150 items covering eight categories, and also send our own inspectors to conduct on-site assessment verifications. Feeding back the results of these audits, we consider solutions to issues together with affiliated plants, and in so doing seek to raise safety and quality in the production process, as well as cultivate relationships of trust.

Ensuring Safety and Comfort for Customers Using Our Vending Machines
Ensuring Safety and Comfort for Customers Using Our Vending Machines

At DyDo DRINCO, we view vending machines as customer-facing "retail outlets," and work to ensure a retail environment that customers can use in comfort. Each vending machine has a team member assigned to it who is responsible for visits, resupplies, and product lineup changes, as well as collecting empty cans and bottles, and cleaning up the immediate vicinity. Through our unique system, we monitor vending machine stocking levels and conduct thoroughgoing quality control right up until the point of consumption.

Using Good Water

Water is a vital ingredient for energy drinks, as it comprises the bulk of the beverage. DAIDO Pharmaceutical's plant is located in an area with rich natural resources, and high-quality underground water is pumped up for use, and well water is purified. In the process of purifying well water, quality checks are performed three times a day using an inspection sheet devised in-house, along with other measures employed to secure and maintain the safety of water used as the base for our energy drinks.

Among general utilities for supporting the manufacturing process, I am in charge of maintenance and management of water equipment. Awareness of water has changed in recent years, including from the perspective of food safety, and we are working hard in maintenance and management to further improve the quality of water-related equipment. For example, we periodically review and update the check items in the inspection chart used for quality inspection of processes involving water for manufacturing to ensure they are optimal. Going forward, we will continue to keep in mind that "good water is good for people," and work to provide products with higher safety that can contribute to the health and happiness of our customers. We want to continue improving, with the objective of maintaining our position as No. 1 in the industry in terms of quality as well as sales.

Food Defense Measures
Food Defense Measures

DAIDO Pharmaceutical takes food defense measures for building a safe, concern-free production system. Entry into the plant is restricted by ID card, and over 100 quality assurance cameras are set up inside and outside the plant to capture footage that can be used for analysis if trouble ever does occur in the manufacturing process. In addition to strengthening such physical measures, we have established an open and transparent workplace environment where management and team members can mix freely and engage in unfettered interaction on a daily basis.

Our Approach to Quality at Tarami

At Tarami, we consider thorough quality management to be an essential condition for delivering tasty food products to our customers. The company is certified under both the ISO 9001 international standard for quality management systems and FSSC 22000 international certification scheme for food safety systems. Moving forward, we will continue to conduct strict quality and product inspections and aim to further improve quality.
