Frequently Asked Professional Questions (FAQ)
We've compiled answers to some of the most common technical questions we receive from professional buyers.
Caliber refers to the diameter of the walnut at its widest point, measured in millimeters (mm). It is a critical specification for several reasons. Firstly, for buyers using automated cracking machines, a consistent caliber is essential for the machinery to operate efficiently and minimize kernel breakage. Secondly, in a retail setting, larger, uniform walnuts have a higher perceived value and better shelf appeal. We use precision mechanical graders to sort our walnuts in shell bulk into specific calibers like 28mm, 30mm, and 32mm+ to meet these diverse commercial needs.
The ideal moisture content for long-term storage of walnuts in shell is 8% or less. Above this level, the risk of mold and aflatoxin development increases dramatically, compromising the entire shipment and posing a food safety risk. Below 5%, the kernel can become overly brittle. We control this critical parameter using large-scale, controlled-environment drying rooms. Unlike sun-drying, which can be uneven, our method circulates air at a consistent, low temperature, gradually bringing the moisture down to the target
Optical sorting is a high-technology quality control step that uses high-speed cameras and computer algorithms to inspect each individual walnut. The cameras can identify discoloration, cracks, stains (from mold), or misshapen shells that may indicate a poor-quality kernel inside. When a defective walnut is detected, a precise puff of air removes it from the production line. This technology operates at a speed and accuracy that is impossible to achieve with the human eye alone, allowing us to significantly reduce the "imperfect rate" to below 5% and deliver a cleaner, more reliable final product.
Yes, our Xinjiang Xinfeng variety is renowned for being 'paper-shelled' or 'thin-shelled'. While not an official grading term, it's widely used in the industry to describe walnuts with a shell thickness typically between 0.8mm and 1.2mm. This is significantly thinner than many other varieties, which can have shells up to 2.0mm thick. The primary technical advantage is a much higher kernel-to-shell ratio (kernel rate), often exceeding 55%. This means buyers get more edible product for the same weight, directly improving their return on investment.
To maximize the 12-month shelf life, we recommend storing the walnuts according to HACCP and GMP (Good Manufacturing Practices) guidelines. The ideal storage conditions are:
Temperature: Between 0-10°C (32-50°F).
Relative Humidity: Between 55-65%.
Environment: A clean, dry, and well-ventilated warehouse, away from direct sunlight and strong odors (as walnuts can absorb ambient smells).
Following these protocols will preserve the freshness, crispness, and flavor of the kernels.
Yes, upon request, we can provide a Certificate of Analysis (COA) for each batch of walnuts in shell bulk that we ship. This document provides third-party or in-house lab-verified data for key quality parameters, including moisture content, aflatoxin levels (e.g., B1, B2, G1, G2), kernel rate, and peroxide value. The COA is a critical document for quality assurance and is often required for customs clearance in many countries, providing our clients with an extra layer of confidence and trust.
Our raw walnuts are 100% natural. The only "treatment" they undergo is washing with clean water and controlled-air drying. Some producers, to achieve a whiter shell appearance, may use chemical bleaching agents like sodium hypochlorite or fumigants like sulfur dioxide. We strictly avoid these practices. Chemical treatments can alter the natural taste of the kernel and may leave residues. By offering a truly raw and natural product, we cater to the growing market demand for clean-label, unprocessed foods and ensure the authentic, rich flavor of the Xinjiang walnut is preserved.
