Frozen Sliced Beans

Main Product: IQF Cross-Cut Green Beans

We prepare the standard product from fresh, clean and sound pods of Phaseolus vulgaris L. Suitable raw material is trimmed, washed, cut transversely, blanched, cooled, individually quick frozen, sorted and packed. The standard ingredient declaration is 100% green beans, without added salt, sugar, color or preservative.

The 20–40 mm cut offers controlled portioning and even distribution in foodservice sides, ready meals and frozen vegetable blends. Length alone is not enough: pod diameter influences maturity, fiber, cooking time and visual uniformity. We therefore quote length and diameter as separate fields.

Product Forms and Exact Style Definitions

We keep the form name and the physical definition together. Codex defines cut beans as transversely cut pods in which at least 70% by count are 20–65 mm long, short cut as pieces more than 10 mm but less than 20 mm, and sliced beans as pods sliced lengthwise or at an angle with a maximum thickness of 7 mm. Our commercial offers narrow these broad definitions to the requested production range.

Length, Diameter and Grade Selection

Cut length controls piece count and visual distribution. Diameter is a separate maturity and texture variable. For round-type beans, recognized diameter references include extra small up to 6.5 mm, very small up to 8 mm, small up to 9.5 mm, medium up to 11 mm and large over 11 mm. We normally quote practical production bands such as 6–8 mm, 7–9 mm or 8–10 mm and state whether the measurement applies before or after freezing.

Diameter measurement is recorded separately from the 20–40 mm cut length.

Standard Grade A starting point: at least 85% by count within the nominated cut-length band; natural green and reasonably uniform color; tender character after controlled preparation; no objectionable flavor or odor; and the numerical defect limits shown below.

Processing grade: a wider size distribution and broader cosmetic tolerance can reduce cost for soup, sauce, filling or blended processing where the bean is not the main visible component. Food-safety, foreign-material and pathogen requirements are not relaxed.

Commercial Product Specification

Defect Tolerances for a Grade A Quotation

USDA and Codex grade systems distinguish extraneous vegetable material, stems, blemishes, mechanical damage, short pieces, color defectives and fiber. We convert those categories into a readable commercial starting profile. The signed specification states the sample size, unit of measure and whether a sub-limit is included in the total defect tolerance.

Factory Process and Blanching Control

1. Raw-material reception: we inspect variety, maturity, color, pod diameter, field defects and lot identity.
2. Trimming and washing: we remove ends and plant material, then wash the pods before cutting.
3. Cutting and calibration: we set the cross-cut, short-cut or French-style form and check the declared dimensions.
4. Blanching: we apply a controlled heat treatment to stabilize color and flavor. Peroxidase can be specified as negative when required.
5. Cooling and draining: we stop the heat process and remove excess surface water before freezing.
6. IQF freezing: we pass the product quickly through the principal ice-crystal formation range and bring the thermal center to −18°C or below.
7. Final inspection and packing: we check defects, free-flowing condition, foreign material, metal-control result, net weight, seal and code.

Foreign-Material and Pack Inspection

Natural raw material can carry plant matter, stems, field debris or damaged pieces into the process. We combine washing, sorting, visual inspection and the applicable detection equipment. The finished specification defines visible foreign material as absent in the inspected sample; detector settings and verification records follow the plant's validated control program.

Microbiological, Residue and Heavy-Metal Profile

We quote the microbiological criteria against the product's intended use and destination. Our standard commercial target below is more demanding than many general industrial frozen-vegetable specifications. A retailer, ready-to-eat program or buyer-specific sampling plan can require a different scope and is priced accordingly.

For EU orders, pesticide residues are assessed against the MRL applicable to beans with pods and the selected active substances. Where no specific MRL is set, the general default is 0.01 mg/kg. Our EU-oriented heavy-metal starting limits are lead ≤0.10 mg/kg and cadmium ≤0.020 mg/kg on wet weight, with the legally applicable destination requirement taking precedence. The offer states the multi-residue panel, laboratory scope, reporting limit and testing frequency instead of using a vague "residue compliant" sentence.

Sampling and COA Actual Results

For size inspection, we take a representative frozen sample from cartons distributed across the lot. Pieces are mixed, measured and separated into in-range, undersize and oversize groups. We report cut-length conformity by count and small fragments by weight. For diameter-calibrated product, a 1 kg frozen sample provides the measurement basis unless the signed plan states another quantity.

Defect inspection separates plant material, stems, blemishes, mechanical damage, color defects, strings and fiber instead of placing every nonconformity into one undefined total. Codex uses 1 kg for extraneous vegetable material and stem ends and 300 g for other visual defect categories; a buyer plan can use a larger composite sample for higher-volume lots. The agreed method remains the same for pre-shipment release and arrival review.

We provide a batch COA according to the contracted test scope. The specification limit is the maximum or minimum acceptance criterion. The Actual Result is the result measured for the applicable production-lot sample; it is not copied from the specification and is not described as an actual value before testing. Typical COA fields include lot number, production date, cut, organoleptic result, microbiology and peroxidase where required. Residues and metals can appear on the COA, an accredited laboratory report or both.

Application Matching

Packaging, MOQ and Private Label

For private label, we review bag dimensions, film structure, seal area, net weight, units per carton, label language, nutrition-panel input, barcode position, date coding, carton marks and pallet requirement. The approved artwork revision is linked to the order. Net-weight and seal checks form part of the packing release.

Documents, Certification Files and Traceability

We prepare the product specification, batch COA, packing list, commercial invoice, bill of lading and certificate of origin for the applicable order. A health certificate, phytosanitary certificate, residue report, heavy-metal report, microbiological report, temperature record and pallet statement can be included according to the destination and sales agreement.

The lot code links raw-material reception, processing date, cutting specification, blanching, freezing, packing, frozen storage and shipment records. Certification support is stated by production site, scope and validity. A facility certificate is not described as a product-specific certificate, and certified organic status is offered only for an order covered by valid organic scope and transaction documentation.

Cold Storage and Reefer Loading

We hold finished product at −18°C or below and maintain the frozen state during staging and loading. Repeated thawing and refreezing can increase clumping, surface ice, color loss and texture damage, so carton condition and product temperature are reviewed before shipment. Standard shelf life is 24 months in unopened packs under continuous frozen storage.

A 20-foot reefer normally plans approximately 10–12 metric tons. A 40-foot high-cube reefer normally plans 22–24 metric tons. The final payload depends on carton dimensions, palletization, carrier equipment and destination weight limits. We state the practical loading quantity in the sales confirmation.

Blanching Verification and Processing Performance

Blanching is a functional control step rather than a marketing phrase. Insufficient heat treatment can leave enzyme activity that contributes to color and flavor deterioration during frozen storage. Excessive blanching can weaken brightness, soften the pod and increase sloughing, where the outer surface separates from the bean tissue. We balance time and temperature against pod diameter, cut form, line load and downstream use.

Peroxidase is commonly used as a practical indicator of blanching adequacy. When the buyer's specification requires it, we include peroxidase: negative as an acceptance field and place the applicable result on the COA or production record. That result does not replace texture evaluation. A bean can pass an enzyme test yet still be unsuitable for a long secondary heating process if the raw-material maturity or blanching profile does not match the application.

For ready meals, foodservice and institutional programs, we recommend an application trial using the nominated cut and diameter. The frozen sample should be evaluated after the actual regeneration method, sauce contact and holding time. We can record color, tenderness, fiber, broken-piece development and drained yield under a written test condition. Cross-cut 20–40 mm pieces generally provide even distribution, while a larger diameter or longer piece gives stronger visual identity but may require a longer heating profile.

A drain-loss comparison must state the frozen sample weight, heating or thawing condition, screen size, drain time and calculation. Results from different methods cannot be compared as if they were the same test. Where water release affects sauce viscosity, tray fill or net yield, the approved sample and repeat-order specification should use one fixed procedure.

Pre-shipment Acceptance and Retained Samples

Our release review connects physical inspection, laboratory scope, packing checks and frozen condition to the same lot code. A pre-shipment sample can be assessed for cut distribution, diameter, color, defect categories, fiber, free-flow condition, net weight, bag seal, carton marks and sensory character. Laboratory samples remain separately sealed and identified so microbiological or chemical results are not confused with the physical sample.

For recurring programs, the quality agreement can state how many cartons are selected, the composite sample mass, the number of sample units and the acceptance rule. Codex references an AQL of 6.5 for presentation and quality factors, while retailer or industrial programs may use their own sampling plan. We do not describe one small hand sample as proof of an entire shipment unless the agreed plan permits that conclusion.

Where retained samples are required, the agreement states quantity, seal identification, retention period and storage temperature. We keep the sample frozen at −18°C or below. If an arrival result is disputed, the retained sample provides a lot-linked reference, but it is interpreted together with transport temperature, container condition, arrival sampling and laboratory method.

Product photographs can document appearance and packing, but they do not replace measured results. The accepted sales specification, sample record, COA and shipment file provide the commercial evidence for release.

Order Change Control and Arrival-Claim Evidence

The sales specification carries a revision date or number and is linked to the purchase order. It records the product name, species, style, cut direction, length, diameter, grade, defect limits, blanching status, microbiology, chemical scope, packing, storage, shelf life and documents. Artwork, carton marks and pallet configuration are approved as separate controlled files.

If crop availability requires a different variety, diameter band, production site, pack material or test scope, the changed field is presented before shipment. A substitution is not allowed to silently turn cross-cut beans into French-style strips, widen 20–40 mm into an ungraded cut or replace a contracted retail film. Written approval keeps the changed order traceable.

For an arrival claim, the useful evidence set includes purchase order, specification revision, container and seal numbers, bill of lading, temperature recorder, affected carton quantity, outer and inner-pack condition, lot-code photographs, sampling method, photographs of the frozen product and the test report. Unopened affected cartons and a representative frozen sample should be preserved where practical. These records help separate a specification deviation from transport damage, temperature abuse, seal failure or handling after arrival.

Claim timing and inspection rights belong in the sales contract. A clearly documented review establishes what was ordered, what was shipped, how the product was handled and what the measured deviation is.

Frequently Asked Questions

1. Are frozen sliced beans the same as frozen cut green beans?

They often refer to the same transverse-cut product, but "sliced" can also mean French-style lengthwise strips. We write the cutting direction and dimensions into the quotation to prevent a form mismatch.

2. What is the standard cut length?

Our main cross-cut specification is 20–40 mm. We also supply 30–50 mm, 40–60 mm and 10–20 mm short cut according to the application and volume.

3. What is French-style sliced green bean?

French style means the pod is sliced lengthwise, or at a limited angle to the longitudinal axis, into thin strips. We quote a maximum thickness of 7 mm and keep it separate from cross-cut beans.

4. Can you control green bean diameter?

Yes. Practical bands include 6–8 mm, 7–9 mm and 8–10 mm. Diameter and cut length are measured as separate specification fields.

5. Are the beans blanched before IQF freezing?

Yes. We trim, wash and cut the beans, apply controlled blanching, cool and drain them, then freeze them individually. Peroxidase can be specified as negative where the buyer requires that verification.

6. What Grade A defect limits do you offer?

Our starting profile includes at least 85% within the cut band, small pieces below 10 mm at no more than 5% by weight, mechanical damage no more than 3%, total blemishes no more than 3% and color-defective pieces no more than 2%. The order specification states the sampling unit and final tolerances.

7. How do you control tough strings and fibrous pieces?

We inspect raw-material maturity and include tough strings and fibrous units in finished-product defect sorting. The Grade A starting limit is no more than 1% by count.

8. What microbiological limits are available?

Our standard quotation target is TPC ≤100,000 CFU/g, coliforms ≤100 CFU/g, E. coli <10 CFU/g, yeast and mould each ≤1,000 CFU/g, and Salmonella and Listeria monocytogenes not detected in 25 g.

9. Do you provide pesticide and heavy-metal reports?

Yes. We can provide the agreed multi-residue and heavy-metal scope by lot or monitoring frequency. For EU-oriented business, our starting metal limits are lead ≤0.10 mg/kg and cadmium ≤0.020 mg/kg, subject to the applicable destination rule.

10. Does the COA show actual batch results?

Yes. The specification field shows the acceptance limit, while Actual Result records the measured result for the sampled production lot. We do not use the limit as a substitute for the test result.

11. What bulk and retail packaging can you supply?

Bulk options include a 10 kg PE-lined carton, with 20 lb and 20 kg formats by order plan. Foodservice and retail options include 2.5 kg, 1 kg, 750 g, 500 g and 400 g bags.

12. What is the MOQ and lead time?

Standard bulk cut beans normally start at 10–12 metric tons. Custom cut or retail packing normally starts at 15 metric tons. Lead time is normally 15–20 days after specification, packaging and order details are approved.

13. Can frozen sliced beans be loaded with other vegetables?

Mixed-container planning can begin at 3–5 metric tons per SKU where the production schedule, carton dimensions and destination documents are compatible. Send the full SKU list for a loading plan.

14. What information should be included in an RFQ?

Send the cutting direction, cut length, diameter, grade, defect limits, microbiology, pack format, quantity, destination port, application, private-label needs, document list and delivery window.
