Straight chain starch analyzer: a new benchmark for rapid detection of grain quality

In the field of grain quality inspection and food processing, the content of amylose is a key indicator that determines the edible quality, processing adaptability, and market value of grains. The traditional chemical analysis method is cumbersome, time-consuming (usually several hours), and requires high professional requirements for operators, which seriously restricts the efficiency of large-scale detection. The emergence of amylose analyzers, with their automation, intelligence, and high-precision characteristics, has brought revolutionary solutions to the industry.

Core Technology Principle: Integration of Optoelectronic Detection and Automation

The core principle of the amylose analyzer is based on the characteristic of generating specific color complexes through the reaction of amylose, amylopectin, and iodine reagents. The instrument adopts customized wavelength high stability LED cold light source (straight chain: 470nm&620nm; Branches: 540nm&680nm), precisely irradiate the starch iodine complex solution passing through the colorimetric dish. The solution absorbs light of a specific wavelength, and the photodetector captures changes in the light signal and converts it into absorbance values (range: 0.000-2.000 Abs). The instrument is equipped with precision algorithms and standard working curves, which instantly convert absorbance data into precise contents of amylose, amylopectin, and total starch (detection range: 0-50%, accuracy: ± 1%).

Significant technological advantages, solving industry pain points

Efficiency leap and cost optimization: Integrating peristaltic pump continuous automatic injection and flow detection technology, breaking through the limitation of sample quantity, single sample detection only takes about 20 seconds, combined with 60 minutes of sample pretreatment, greatly improving the detection flux in the laboratory or production line, significantly reducing labor and time costs.

Accurate data, stable and reliable: adopting intelligent constant current voltage stabilization technology and automatic light intensity calibration, the light source works for a long time without temperature drift (long-term drift<1% FS/24 hours), and the transmittance repeatability is excellent (≤ 0.3% T). The detection process involves multiple rounds of lighting to ensure highly reliable data, with a minimum reading of 0.001%.

Intelligent control, convenient management: equipped with Android 7.1 system and 7-inch touch screen, providing efficient and intuitive UI interaction. Equipped with dual channel data output: supports WiFi networking to quickly upload data to the cloud data management platform, enabling visual management of historical data and analysis of long-term and short-term food security; Simultaneously supporting direct copying of USB drives (standard USB interface, driver free), flexibly meeting the needs of different scenarios.

Durable and sturdy, widely applicable: suitable for various environments with temperatures ranging from 0 to 40 ° C and humidity ≤ 90% RH (at 40 ° C), compact design (315 * 180 * 250mm, 3.8KG) for easy mobility and deployment. The new generation of high-speed thermal printers supports instant or batch report printing.

Multi domain applications and value realization

Grain storage and quality inspection institutions: quickly classify and grade, strictly control the quality of raw grain storage, and provide accurate data support for the rotation of reserve grain.

Breeding and Agricultural Research: Efficiently screening excellent varieties with amylose content that meets the target, accelerating the breeding process.

Food processing enterprises: precisely control the proportion of raw materials (such as Rice noodles, corn starch, and vermicelli production), optimize the processing technology (such as cooking and puffing), and ensure the stable and consistent quality of end products (such as rice taste, noodle toughness, and snack food crispness).

Market supervision: Quickly screen the quality of grain and oil products in circulation, crack down on adulteration and fraud, and protect consumer rights.

Empirical application cases:

A large flour processing enterprise in East China has long been affected by fluctuations in the amylose content of raw wheat, resulting in poor quality stability of its specialty flour. After introducing the amylose analyzer, rapid (20 seconds/sample) and precise (accuracy ± 1%) screening of each batch of wheat entering the factory has been achieved. Through data platform analysis, the enterprise successfully established a raw material database and optimized the wheat blending plan. Within just six months, the quality control pass rate of specialized powder has increased by 12%, and the customer complaint rate has significantly decreased, effectively enhancing market competitiveness and efficiency.
