Sample Preparation

Accurate quality testing begins with standardized sample preparation. Whether for wheat, paddy rice, or milled rice samples, analyses of protein, gluten, starch, nutritional components, and safety indicators require standardized pretreatment steps—sampling → dehulling → grinding → weighing—to ensure accuracy and reproducibility of test results.

Paddy Dehulling and Milled Rice Preparation

For rice quality testing, paddy rice must first be processed into brown rice and then into milled rice.

  • Small-scale husker → used for rapid removal of rice husks to obtain standard brown rice samples
  • Small-scale whitener → further removes the bran layer and germ from brown rice to prepare milled rice samples that meet testing requirements, providing a basis for determining head rice yield, chalkiness, palatability score, and nutritional composition analysis.
  • Rice mill → combines the “dehusking” and “whitening” steps into a single integrated machine.
  •  

Sample Grinding and Homogenization

To ensure uniform particle size and good reproducibility of test samples, cereals or milled rice need to be ground.

  • Hammer cyclone mill → widely used; samples are pulverized into fine, uniform powder by high-speed hammers; used for gluten value, falling number, viscosity, fatty acid value, and near-infrared (NIR) analysis of protein
  • Pneumatic grinding mill → prepares samples for aged-grain testing and wheat wholemeal gluten determination; used for gluten value, falling number, viscosity, fatty acid value, and near-infrared (NIR) analysis of protein
  • Laboratory flour mill → a pretreatment instrument for dough rheological testing, serving as a front-end preparation device for farinographs, extensographs, and alveographs

Dough Rheology

Dough rheological properties are important indicators for evaluating the processing performance of flour. By simulating the changes in dough during mixing, fermentation, and processing, these tests analyze flour’s water absorption, stability time, degree of softening, and extensibility.

Electronic Farinograph – Extensograph – Alveograph

  • Electronic Farinograph
  •  
  • The Electronic Farinograph is used to measure the rheological properties of dough during the mixing of flour with water. It is one of the most commonly used quality evaluation instruments in flour mills, baking enterprises, and research institutions.By recording the changes in dough resistance during mixing, it evaluates the water absorption capacity of flour and dough stability, providing a basis for recipe formulation and quality control.
  •  
  • Extensograph 
  •  
  • The Extensograph is used to measure the mechanical properties of fermented dough during stretching, simulating the extensional behavior of dough during fermentation and processing.This instrument evaluates the strength and extensibility of the gluten network structure and is an important piece of equipment for quality evaluation of bread flour and high-gluten flour.
  •  
  • Alveograph
  •  
  • The Alveograph continuously inflates a dough film until it bursts, simulating the behavior of dough during fermentation and baking as gas expands.
  • Widely used in European and international flour trade, it is an important tool for evaluating the quality of bread flour, baguette flour, and pizza flour.

Gluten Quality

Gluten is a key component that determines dough structure and processing quality. Gluten quality directly affects bread volume, noodle elasticity, and baking performance.

Our gluten testing system consists of three independent instruments: a Gluten Washer, a Gluten Index Centrifuge, and a Gluten Dryer. Together, they can simultaneously provide important indicators including wet (and dry) gluten content, gluten index, and gluten water retention capacity.

Starch & Enzyme Activity

Starch properties and enzyme activity determine flour gelatinization behavior, fermentation characteristics, and the texture of final products. These tests are widely used in flour processing, grain trading, and food research and development.

Falling Number Analyzer 

The Falling Number Analyzer is mainly used to determine α-amylase activity in flour or cereals. When grains undergo sprouting or become damp, α-amylase activity increases, accelerating starch degradation, which leads to poor dough structure, bread collapse, and reduced product quality. Therefore, falling number has become an important indicator in international grain trading and flour quality evaluation.

Amylose Analyzer

The ratio of amylose to amylopectin determines the texture, viscoelasticity, staling rate, and eating quality of food products.

  • Rapid Visco Analyzer (RVA) 
  •  
  • The RVA measures viscosity changes during starch gelatinization by simulating the heating, holding, and cooling processes.

Rapid Composition

A spectrophotometer can quickly detect some components of flour, but it cannot fully reflect the processing quality of flour. For key indicators such as gluten quality, dough rheological properties, and starch gelatinization properties, it is still necessary to use professional equipment such as gluten analyzer, flour analyzer, tensile analyzer, RVA rapid viscosity analyzer, etc. for accurate measurement.
