Raw Material Risk Management for Food Manufacturers and How to Use Dried Vegetables

What you will learn from this article

• The overall picture of raw-material sourcing risks food manufacturers face
• Measures for each of bad weather, import restrictions, and logistics stagnation
• Concrete methods of risk hedging using dried vegetables
• The way of thinking about building raw-material sourcing into a BCP (business continuity plan)
• Supplier selection criteria for building a stable sourcing structure

In the summer of 2024, a record heat wave temporarily sent the price of leafy vegetables jumping more than double. At that time, many sourcing managers must have rushed to secure raw materials.

Honestly, such situations are likely to happen more frequently going forward. For food manufacturers facing climate change, environmental risk, and supply anxiety over raw materials, systematic analysis of raw-material risk, in-house training, and the development of various BCP systems have become urgent tasks. Climate change, geopolitical risk, labor shortages — the risks surrounding raw-material sourcing only increase, with no sign of decreasing.

We at Agriture manufacture dried vegetables in Kyoto, and consultations from our client food manufacturers about "how to prepare for the risk of raw materials becoming unavailable" have clearly increased over the past two to three years. This time, drawing on that field experience, we will organize practical methods of raw-material risk management.

Types of raw-material sourcing risk food manufacturers face

Bad weather and natural disaster risk

The most familiar and impactful risk for food raw materials is weather-related risk. Let us organize the concrete patterns.

It is easy to overlook, butover-advanced growth caused by a warm winteris a genuine risk too.Napa cabbageand daikon reaching harvest all at once triggers a troublesome pattern: the market crashes temporarily, and then supply dries up during the off-season gap.

Import restrictions and geopolitical risk

If you rely on overseas raw material procurement, import restrictions and geopolitical risk cannot be ignored either.

Recent cases still fresh in memory include the following.

• Tighter residual pesticide standards for agricultural produce imported from China
• Delays in ocean shipping and surging freight rates due to container shortages
• Import suspension measures against specific countries (political factors)
• Export restrictions in the country of origin (imposed on grounds of domestic food security)

Such risks are hard to predict and their impact is significant when they materialize, so the higher an item's import dependence, the more important it is to secure alternative procurement sources.

Logistics and supply chain risk

Even if there is no problem with the raw material supply itself, it means nothing if you cannot move it. Logistics risk has surfaced rapidly in recent years.

• The 2024 Problem: Reduced transport capacity due to tighter regulations on drivers' overtime work
• Surging fuel costs: Rising logistics costs passed on to raw material costs
• Port strikes: Delayed arrival of imported raw materials
• Shortage of warehouse capacity: Chronic shortage of available refrigerated and frozen storage

Fresh raw materials that require refrigeration or freezing in particular take the full brunt of logistics constraints. This is where we want you to note the logistical advantages of dried vegetables.

Why dried vegetables serve as a risk hedge

Long-term storage at room temperature

The greatest strength of dried vegetables is that they can be stored long term at room temperature for one to two years. Since no refrigeration or freezing equipment is needed, storage costs are greatly reduced and logistical risk is mitigated as well.

Let's compare the storage conditions of fresh and dried vegetables.

Because the weight drops to roughly 5–15% of the fresh product,transport costs are also greatly reduced. This really pays off especially when procuring from distant sources.

Buffering the impact of poor weather with inventory

With fresh vegetables, trying to respond after bad weather hits is already too late. Dried vegetables, however, let you hold inventory bought cheaply in normal times so it functions as a buffer during periods of poor weather.

As a concrete operating method, the following inventory strategy is effective.

• Standard inventory: 1 to 1.5 months of monthly usage
• Safety inventory: 0.5 to 1 month of monthly usage (a hedge against weather risk)
• Strategic inventory: additional volume procured when prices are low (1 to 2 months of monthly usage)

Combining these three layers of inventory builds a system that can withstand supply disruptions of around three to four months.

Consistent quality and stable specifications

Fresh vegetables vary in quality by growing region and season. Size, color, taste, moisture content—anyone in quality control knows well that every fluctuation in these requires adjusting the production line.

Because dried vegetables have their moisture content and cut size managed uniformly during the manufacturing process,specification variance is small, which is a defining feature. When raw material specifications are stable, product quality control becomes far easier.

How to build raw material procurement risk into your BCP (business continuity plan)

Set priorities with risk mapping

Applying the same level of countermeasures to every raw material is not realistic. Start by setting priorities with risk mapping.

Evaluate each raw material along the following two axes.

• Impact: How much impact the business would suffer if that raw material became unavailable
• Likelihood: How frequently the procurement risk materializes

Prepare a list of alternative raw materials in advance

We strongly recommend preparing an "alternative raw material list" for each of your core raw materials. Completing quality tests and prototype runs for substitutes during normal times makes switching in an emergency go smoothly.

The information to include in the alternative raw material list is as follows.

• Name and specifications of the alternative raw material (cut size, moisture content, color tone, etc.)
• Supplier information (manufacturer name, contact, minimum lot, lead time)
• Quality test results (differences from the existing raw material, impact assessment on the product)
• Production line adjustments required when switching
• Estimated cost difference

At Agriture, we also propose alternative recipes using multiple dried vegetable raw materials and provide prototype support for our food manufacturer clients. Preparing from the "we might use it someday" stage makes a world of difference in your initial response when the need actually arises.

Build an information-sharing framework with suppliers

A BCP cannot be completed by your company alone. It is important to agree with suppliers during normal times on the communication framework and alternative supply arrangements for when a risk materializes.

Specifically, having arrangements like the following provides reassurance.

• Emergency contacts and communication flow (including backup contacts when the person in charge is unavailable)
• Timing for sharing information when an event affecting raw material procurement occurs
• Priority order when supply becomes difficult (what percentage of the existing contracted volume is guaranteed)
• Process and approval flow for switching to alternative products

Steps to build a dual-source system

Step 1: Visualize your current procurement structure

The first thing to do is to "make visible" how concentrated your current raw material procurement is. Organize the following items.

• Number of suppliers and order share per item
• Each supplier's dependence on growing regions (whether there is concentration in a specific region)
• Ratio of imported to domestically grown products
• Procurement lead time (from order to delivery)

Step 2: Clarify the criteria for selecting a second source

When choosing a new supplier, evaluate not just on price but from the following viewpoints.

Step 3: Diversify orders in phases

Switching orders drastically all at once carries risk. A phased approach like the following is recommended.

1. Evaluation phase(1–2 months): sample evaluation, factory audit, prototype testing
2. Trial operation phase(3–6 months): switch 10–20% of the total to the new supplier
3. Full operation phase(6 months onward): expand the ratio to 30–40%
4. Stable operation phase: stabilize at 60–70% main and 30–40% secondary

Concrete examples of procurement strategies using dried vegetables

Case 1: Partial switch from frozen vegetables to dried vegetables

One prepared-foods manufacturer switched part of the frozen spinach it used as a soup ingredient to driedSpinach,.

The effects it achieved as a result are as follows.

• Reduced freezer space by 30%
• Near-zero disposal of raw materials past their best-before date
• Able to cope with three months of inventory even during poor weather
• Reduced logistics costs (freezer truck → ambient truck)

Case 2: A stable procurement system for domestically grown raw materials

For manufacturers that make "use of domestically grown vegetables" a product differentiator, securing a stable supply of domestic raw materials is a lifeline. Relying solely on fresh domestic vegetables carries the risk of procurement grinding to a halt in a year of poor weather.

Holding domestically grown dried vegetables as strategic inventory is a growing approach to hedging supply risk while maintaining a "100% domestic" claim.

Case 3: Domestically grown dried vegetables as a response to import risk

There are also increasing cases of manufacturers that had depended on Chinese dried vegetables moving forward with a phased switch to domestic products in response to geopolitical risk. At Agriture, when we receive inquiries about such a switch, we propose a phased transition plan that accounts for quality and price.

FAQ

Q1: Do the taste and texture change when switching to dried vegetables?

To be honest, they cannot be exactly the same as fresh vegetables. That said, when used in heat-cooked dishes such as soups, stews, and takikomi rice, the texture and flavor after rehydration return to a level close to fresh. Selecting the right item for the application and optimizing the rehydration conditions matter.

Q2: How much safety inventory of dried vegetables should I keep?

Generally, 2 to 3 months of monthly usage is the benchmark. Since they store at room temperature and take up little space, the hurdle to holding inventory is lower than with fresh or frozen. Building up inventory before summer, when weather risk is high, provides reassurance.

Q3: What are the minimum requirements to ask of a supplier for BCP purposes?

Confirm at minimum these three points: HACCP certification, an established emergency communication framework, and a commitment to alternative supply (what percentage of the contracted volume is guaranteed). If possible, you should also conduct a supplier audit about once a year.

Q4: Are there any items that domestically grown dried vegetables cannot cover?

Vegetables not cultivated domestically (such as some herbs) naturally have no domestic product. Also, for items likegarlic, where domestic production is limited, it can be difficult to secure the entire volume domestically. It is important to check the domestic supply capacity for each item in advance.

Q5: How long does it take to build a dual-source system?

Expect roughly 6 months to 1 year from quality evaluation to stable operation. Quality testing and verification on the production line in particular take time. Scrambling to find a source only after a risk materializes is too late, so the key is to start with plenty of lead time.

Q6: What evaluation points are especially important when selecting a dried vegetable manufacturer?

The three points are the quality control system (certifications such as HACCP and FSSC 22000), transparency of raw material growing-region information, and manufacturing capacity for stable supply. Choosing on price alone often leads to headaches over inconsistent quality and unstable supply, so caution is needed.
