Quality Control

Quality Control

Tianz Grain Products Co., Ltd. applies structured quality control practices to support the safety, consistency, and specification compliance of grain ingredients, staple foods, baked products, snacks, noodles, cereals, and grain-free food and pet food products. Quality requirements are defined according to the product type, customer specifications, intended market, and applicable regulatory expectations. Inspection records and production information are maintained to support traceability and effective communication with international buyers.

1. Incoming Material Inspection

Quality control begins with the evaluation of incoming grains, flours, starches, ingredients, packaging materials, and other production inputs. Materials are checked against internal acceptance criteria and purchasing specifications before they are released for use.

• Identity and documentation: Product names, lot information, supplier documents, and specified material details are reviewed.
• Physical condition: Materials are examined for appearance, color, odor, cleanliness, moisture-related concerns, infestation, and visible foreign matter.
• Specification checks: Relevant characteristics may include moisture, particle size, composition, and other product-specific parameters.
• Packaging integrity: Bags, cartons, liners, seals, and labels are inspected for damage, contamination, or incorrect identification.
• Risk-based verification: Additional testing may be arranged when required by the product specification, customer agreement, or destination-market requirements.

2. In-Process Quality Control

Production conditions are monitored at defined stages to reduce variation and help ensure that each batch follows the approved process. Controls are adapted to operations such as cleaning, milling, blending, forming, baking, drying, cooking, extrusion, and packing.

• Process parameters such as time, temperature, moisture, weight, and mixing conditions are monitored where relevant.
• In-process samples may be evaluated for color, texture, flavor, aroma, dimensions, bulk density, or cooking performance, subject to the product type.
• Measures are applied to manage foreign-material risks and maintain appropriate production hygiene.
• Allergen-related controls and production sequencing are managed according to formulation and facility procedures.
• Nonconforming materials are identified and controlled to help prevent unintended use or release.

3. Finished Product Inspection

Finished products are assessed against agreed specifications before release. Inspection plans vary across wheat, corn, rice, oats, barley, millet, buckwheat, quinoa, rye, sorghum, noodles, pasta, breakfast cereals, bakery products, snacks, and grain-free products.

• Appearance and sensory characteristics: Color, shape, surface condition, aroma, texture, and overall uniformity are reviewed as applicable.
• Physical and compositional characteristics: Net weight, dimensions, moisture, particle size, or other specified attributes may be verified.
• Performance: Cooking behavior, rehydration, baking performance, crispness, binding properties, or palatability-related characteristics may be evaluated according to the intended application.
• Food safety parameters: Relevant chemical, microbiological, allergen, and contaminant checks are determined by product risk, specifications, and applicable requirements.
• Lot identification: Batch information is reviewed to support product identification and traceability.

4. Packaging and Pre-Shipment Checks

Packaging is reviewed to help protect products during storage and international transportation. Before shipment, Tianz Grain Products Co., Ltd. verifies key order details against the approved commercial and product requirements.

• Primary and secondary packaging is checked for cleanliness, integrity, sealing, and suitability for the product.
• Labels are reviewed for product identity, lot coding, net content, date information, and customer-specific details where applicable.
• Pack quantities, carton markings, pallet configuration, and shipping marks are checked against order instructions.
• The loading area and transport container may be inspected for cleanliness, dryness, visible damage, unusual odors, and other conditions that could affect the goods.
• Required inspection and shipment documents are reviewed for completeness before dispatch.

5. Feedback, Corrective Action, and Continuous Improvement

Customer feedback and quality concerns are documented and reviewed to identify the relevant product lot, process stage, and possible cause. When an issue is confirmed, appropriate containment, corrective action, and follow-up measures are determined based on the findings.

Inspection results, production observations, supplier performance, and customer requirements are used to refine internal controls. This practical improvement process helps Tianz Grain Products Co., Ltd. maintain consistent communication, strengthen risk management, and support dependable long-term cooperation with B2B customers.
