Import Black Glutinous Rice Flour — Buy in Bulk from Supplier in Thailand

Black glutinous rice flour from Khumsub Asia Goods Trading Co., Ltd. is milled from Oryza sativa var. glutinosa, a waxy rice cultivar that yields a starch composition of nearly pure amylopectin with negligible amylose content. The source material is black glutinous rice, whose pigmentation derives from anthocyanin compounds concentrated in the pericarp, giving the flour its characteristic deep purple-black hue. Available packaging configurations span 200 g retail pouches through 50 kg industrial sacks, with intermediate sizes at 500 g, 1 kg, 5 kg, 10 kg, 15 kg, and 20 kg. The supplier lists this material as export grade, though buyers should independently verify current lot analysis certificates and any claimed ISO or FSSAI documentation directly with Khumsub Asia Goods Trading Co., Ltd., as response rate data is not available.

The flour exhibits typical glutinous rice flour functional properties: high swelling power upon gelatinisation, pronounced paste clarity, and a sticky, cohesive texture when hydrated. Standard milling yields a particle size distribution of 80-120 mesh for most food manufacturing applications, though the supplier does not specify exact fineness. Typical moisture content for commercially stable rice flour ranges 10-14% to prevent rancidity and microbial growth during tropical storage. The black colouration indicates elevated antioxidant activity relative to white glutinous rice flour, with anthocyanin retention dependent on drying temperature and milling intensity. Buyers should request per-lot spectrophotometric data if colour consistency is critical to their formulation.

Primary applications include traditional Southeast Asian desserts (khao niao dam, bubur pulut hitam), gluten-free baking, noodle production, and as a viscosity-building thickener in sauces and fillings. The material serves health-conscious food manufacturers targeting clean-label, naturally pigmented products. Functional food and nutraceutical sectors use this flour in antioxidant-fortified formulations. Import buyers should confirm with Khumsub Asia Goods Trading Co., Ltd. the exact Incoterms, minimum order quantities, and whether packaging includes nitrogen flushing or desiccant sachets for extended shelf stability. Lead times and seasonal availability of Thai black glutinous rice harvests should be discussed prior to contract commitment.

Khumsub Asia Goods Trading Co., Ltd. is a Thai-registered supplier currently classified at harbour trust tier with no recorded response rate or average response time data. The company operates as an trading entity rather than a primary miller, sourcing black glutinous rice flour for export-oriented distribution. Its location in Thailand places it within one of the world's principal glutinous rice production zones, where the cool-season harvest (November-January) typically supplies the bulk of annual milling volume. The listing does not disclose factory ownership, milling equipment, or organic certification status.

The supplier profile contains minimal operational detail: no disclosed headcount, revenue, year of establishment, or named domestic or international clients. Buyers must diligence Khumsub Asia Goods Trading Co., Ltd. directly regarding supply chain transparency, specifically whether the company holds direct milling relationships or sources through aggregators. The absence of response metrics suggests potential communication delays; importers should establish alternative contact channels and confirm sample availability, documentation turnaround times, and whether the supplier maintains bonded warehouse capability for consolidated shipments.
