Control the field, control the quality

One accountable source

Corn is grown on Yuyuan's own farmland — more than 10,000 mu of it in Shandong — rather than bought in from scattered suppliers. One source means one variety, one standard and one party accountable when something needs explaining. There is no point in the chain where the answer to "where did this come from" becomes a company name instead of a field.

Traceable from seed

Because cultivation is ours, every lot traces back to its field and its season. Seed is Longping High-Tech's Shengtian Baizhu; planting, harvest timing and processing dates sit in the same operation. That continuity is what makes clean documentation possible for a destination market rather than merely promised.

Graded before it ships

Ears are selected and graded for sweetness, size and appearance so each format leaves against a consistent specification. Grading against a single known variety is a different exercise from grading a mixed intake — the expected profile is fixed, so deviations are visible.

Speed as a quality control

Corn bound for IQF is processed and flash-frozen within hours of picking. Frozen product is then held and moved at −18°C from our facility onward, so the texture the fast freeze preserved is not given back during storage or transit.
