Silk and husk material
Method D09-01 · proposed order procedure · reviewed 17 October 2026
Definition: Loose corn silk, attached silk, husk leaf and broken cob core are four separate classes; kernel pericarp is not silk.
Sample state: As received frozen; sweet-corn kernels and cob ears are separate sample states; cooked aliquot only after safe-use approval.
Sampling and quantity: Use P1: five sampling positions and separate 500 g analytical units for the proposed contract pilot; preserve pack/stratum identity and use a separate matched unit for destructive tests. For P05 official cob grade, use separate four-ear or eight-short-ear sample units and its method.
Inspection procedure: For kernels spread still-frozen sample on white tray and sieve on buyer-signed mesh; collect loose silk, loose husk and cob core separately. For cob style run the separate official water-thaw route only when P05 grade is contracted; photograph each ear then aggregate attached/loose husk area and dark/readily noticeable silk strand length over the 4-ear or 8-short-ear official sample unit.
Calculation and reporting: Kernel pilot: class g / net kernel g. Cob pilot: attached/loose class g / net cob sample g and affected-ear count/total ears as supplementary observations. P05 grade: total husk square inches and qualifying silk inches across the whole official sample unit; do not grade by affected-ear percentage. Retain all five results. Pool only matching ratios by summed numerators and denominators; report non-ratio measurements separately.
Product control response: Husker/silker and trimmer settings; processor QC keeps material classes distinct. Record adjustment time and affected lot boundary; inspect pre/post adjustment material before deciding rework.
Records: Record lot/pack/harvest identity, sample weight and count, method revision, equipment calibration where used, photographs of each class, raw tally, operator/date and any rework/retest. Retain Husker/silker or sheller setup, cob-trimmer setting, freezer discharge and cold-store event record.
Hold and release: Hold affected lot for buyer-agreed class limits; reclean/regrade and resample before release; do not hide cob-core fragments in a silk total. The actual processor QC identifies and holds the affected lot/stratum, documents any permitted rework and retest, and its authorized quality manager signs release only after the signed criterion and independent safety checks pass; GreenLand coordinates buyer review.
Source applicability: P05 applies only to the corn-on-cob portion of this card and only under its exact grade route. Loose-kernel steps, analytical mass calculations and P1 are proposed buyer methods, with no USDA kernel-grade claim.

Damaged kernels
Method D09-02 · proposed order procedure · reviewed 17 October 2026
Definition: Cracked kernel retains most flesh; broken kernel loses flesh; loose pericarp is a separate skin fragment.
Sample state: As received frozen; sweet-corn kernels and cob ears are separate sample states; cooked aliquot only after safe-use approval.
Sampling and quantity: Use P1: five sampling positions and separate 500 g analytical units for the proposed contract pilot; preserve pack/stratum identity and use a separate matched unit for destructive tests. For P05 official cob grade, use separate four-ear or eight-short-ear sample units and its method.
Inspection procedure: Inspect loose-kernel SKU frozen in one layer; use signed photos to distinguish cracks, missing-flesh broken kernels and loose pericarp. For cob SKU follow P05 water-thawed per-ear broken-kernel counts and short/regular-ear table, excluding cut-end damage as P05 directs.
Calculation and reporting: Loose kernel pilot: separate defect mass/net kernel food mass ×100. Cob grade: count broken/crushed kernels per ear and score under P05 §52.941 Table IV; record official sample size. Retain all five results. Pool only matching ratios by summed numerators and denominators; report non-ratio measurements separately.
Product control response: Sheller or cob-handling setup; compare line-side before/after freezer. Record adjustment time and affected lot boundary; inspect pre/post adjustment material before deciding rework.
Records: Record lot/pack/harvest identity, sample weight and count, method revision, equipment calibration where used, photographs of each class, raw tally, operator/date and any rework/retest. Retain Husker/silker or sheller setup, cob-trimmer setting, freezer discharge and cold-store event record.
Hold and release: Quarantine if buyer's form-specific breakage limit is exceeded; adjust sheller/sorter, then regrade and repeat sample. The actual processor QC identifies and holds the affected lot/stratum, documents any permitted rework and retest, and its authorized quality manager signs release only after the signed criterion and independent safety checks pass; GreenLand coordinates buyer review.
Source applicability: P05 applies only to the corn-on-cob portion of this card and only under its exact grade route. Loose-kernel steps, analytical mass calculations and P1 are proposed buyer methods, with no USDA kernel-grade claim.
