FAQ: Professional Terms on Low GI70 soba

1. What is Glycemic Index (GI) and why under 70 is significant for soba?

GI indicates the carbohydrate absorption rate and its impact on blood sugar. Sub-70 means a slower glucose release, essential for diabetic and prediabetic management. Low GI70 soba is accredited for this property by 3rd-party labs (ISO 17025).

2. What is "moisture content" in semi-dried noodles?

Moisture content is the percentage of water remaining post-drying—here, 21.5%±1.5%. It affects shelf life, texture, and microbial stability. Controlled semi-dry methods (ISO 22000) allow for longer shelf stability and consistent cooking quality.

3. Why is buckwheat the primary material and how is it sourced?

Buckwheat flour provides low GI, high-quality protein, micronutrients, and is gluten alternative friendly. All buckwheat used in Low GI70 soba comes from pesticide-monitored crops, with every batch tested under ISO 17025 labs for residues and trace heavy metals.

4. What testing standards guarantee the safety of Low GI70 soba?

Production, packaging, allergen control, and shelf-life validation are conducted according to ISO 22000, HACCP, and FDA GRAS guidance, including in-process metal/x-ray checks and final batch microbial testing.

5. What is the shelf life and how to store Low GI70 soba?

The shelf life under ambient storage (10–28°C, no direct sunlight, unopened) is 9 months. No artificial preservative is needed due to low-water activity (aW ~0.5). It is recommended to reseal after first opening or refrigerate if not cooked immediately.

6. Are there gluten-free or allergen-controlled variants available?

Yes, upon large volume OEM/ODM request, full gluten-free (wheat-free) versions can be produced using pure buckwheat and selected gluten-free binders. All allergen control protocols comply with FDA 21 CFR 101.9 and EU 1169/2011 regulations.

7. What is the cooking performance (texture, loss) and can it be used in foodservice bain-maries?

Low GI70 soba demonstrates high elastic modulus (3.2–3.7 N/mm²), low cooking loss (<6.1%), and minimal stickiness. Lab/catering simulation shows texture stability up to 40 min in serving pans, ideal for institutional batch serving.

8. What is the procurement/lead time for custom orders?

Standard items: 3–10 business days ex-stock. OEM/ODM received: typically 2–4 weeks after specification approval; all cycles tracked in ISO 9001-enabled ERP.

9. What support/warranty is offered?

All shipments are batch traceable and have a quality warranty of 6 months or shelf expiry (whichever sooner). Technical support (English/Japanese/Chinese) available via online or on-site consult. Onsite product/culinary training for B2B clients.

Delivery Cycle, Warranty & Customer Support

Standard orders (≤5 MT): 3–10 days after payment.
OEM/ODM custom >10 MT: 14–20 days, including sample batch approve period.
6-month quality guarantee (batch traceable, replacement or refund for certified product issues).
24/7 technical and culinary support, installation/training guidance for institutional accounts.
Free sample packs (for approved F&B, institutional clients, via website request).
