If you’ve ever wondered how konjac products are made—whether it’s konjac noodles, vermicelli, or meal replacements—you’re not alone. Behind this plant-based health food is a carefully controlled process that ensures safety, consistency, and quality. Whether production takes place in traditional workshops or modern mechanized factories, the core steps remain the same.

In this article, we walk through the konjac manufacturing process step by step and explain what makes high-quality konjac products stand out in the market.

Overview of the Konjac Production Process

The general production flow includes:

Raw Material Screening → Milling → Formulation → Extrusion & Forming → Freezing → Thawing and Demolding → Shaping and Dehydration → Drying → Final Screening and Packaging

Let’s break down what each stage involves and why it matters.

Raw Material Selection: The Foundation of Quality

Konjac Tuber or Konjac Flour

The primary ingredient in our products is high-glucomannan konjac, sourced directly from our own plantations.

Unlike traditional milling, Eastern Morning utilizes a multi-stage ethanol purification technology in our Anzhou plant to ensure our konjac flour reaches 90–95% glucomannan purity with zero odor — the gold standard for global export.

This high purity level is essential for achieving superior transparency and premium texture in the final product.

Key criteria for raw konjac material:

• Dry and firm, white or light yellow in color
• Moisture content below 15%
• Free of mold, burnt spots, or damage
• Peeling rate above 85%
• Compliant with food hygiene regulations

Rice as a Secondary Ingredient

Some konjac products, especially vermicelli, include rice in the mix for texture or structure. The rice should be:

• Fresh, not moldy or insect-damaged
• Free from rot
• Moisture content under 15%
• Must meet national food-grade standards

Milling: Achieving the Right Particle Size

Both konjac and rice must be finely ground to 60–80 mesh particles to ensure smooth blending and consistent gelling. This uniform texture is critical for high-quality final products, especially noodles or konjac jelly.

Formulating the Recipe

The formulation is a critical factor in product performance. At Eastern Morning, we offer distinct formulations tailored to different market needs:

Dry Konjac Pasta / Rice Formulation

Composition:

• Konjac Flour: 38%–48%
• Rice Flour / Starch: 50%–60%

Characteristics:
High satiety, lightweight for export, and a texture identical to traditional starch-based pasta.

Wet Shirataki Formulation (Traditional)

Composition:

• Purified Water: 97%
• Konjac Flour: 3%
• Alkalizing Agent (Calcium Hydroxide): <0.1%

Characteristics:
Ultra-low calorie (near zero), keto-certified, and ready-to-eat after rinsing.

This versatility allows us to support private label brands in diversifying their healthy food catalogs.

Shaping, Freezing, and Dehydration

Once the mixture is prepared:

• It is molded into desired shapes (like noodles or blocks)
• Then frozen to stabilize its structure
• Later thawed and demolded for further processing

After shaping, the product is dehydrated to remove moisture, which helps enhance texture, extend shelf life, and prepare the product for final drying.

Final Drying and Packaging

After dehydration, konjac products go through a controlled drying process to ensure they reach a stable, low-moisture state. The products are then screened for consistency, removing irregular pieces or defects, and finally packaged for distribution.

Modern facilities often use automated machines for this final stage, ensuring clean, hygienic, and efficient production that meets food safety standards.

Why This Matters for Buyers

Understanding the konjac production process is especially valuable if you are:

• A distributor or wholesaler seeking consistent product quality
• A private label brand looking to ensure food safety compliance
• A food entrepreneur or R&D team developing new konjac-based products

By sourcing from manufacturers that follow this standardized process and use reliable machines for milling, mixing, and drying, you ensure better product texture, safety, and customer satisfaction.
