How to Distinguish the Quality of Longkou Vermicelli from Shandong

Simply put, Longkou vermicelli from Shandong is a dried starch product processed into thread-like or strip-shaped strands using beans and potatoes as raw materials. As demand for Longkou vermicelli grows, many low-quality, overpriced products have flooded the market. Today, we'll help you spot the difference with a keen eye.

When visually assessing the color of vermicelli, hold the product under bright light for direct observation—this is the first method: color identification.

1. High-quality Shandong Longkou vermicelli should be pure white with a lustrous sheen.

2. Lower-quality vermicelli appears slightly dull or faintly brownish with minimal sheen.

3. Inferior Shandong Longkou vermicelli exhibits a dull, grayish color with no luster.

For sensory evaluation of vermicelli texture, first observe directly, then bend or fold it by hand to assess its toughness and elasticity. Boiling the vermicelli reveals whether it was made with bean starch—this is the second method: texture evaluation.

　1. High-quality Shandong Longkou vermicelli should be uniformly thick (with consistent width for wide noodles), free of clumped strands or broken pieces, and exhibit a supple, elastic texture with no impurities.

2. Inferior Shandong Longkou vermicelli is uneven in thickness, contains clumped or broken strands, lacks flexibility and elasticity, and may contain minor general impurities.

3. Inferior Shandong Longkou vermicelli contains numerous tangled strands and broken pieces, mold spots, significant impurities, or harmful contaminants.

Additionally, here's a helpful tip: When purchasing, visually inspect for signs of mold, ensure packaging is sturdy, neat, and aesthetically pleasing, and verify that the packaging clearly displays the manufacturer's name, address, product name, production date, shelf life, ingredients, and other relevant information.
