NIR Grain Analyzer vs. Traditional Methods: Which One Is Right for Your Flour Mill?
The continuous growth of the global population has brought food safety and sustainable production processes to a critical point. In this long and complex journey from field to table, establishing a precise grain quality control mechanism is an essential requirement to ensure proper traceability of the product from raw material to final product and to build the system on a solid foundation.
1. What is NIR Analysis and Why is it Important?
The grain sector is moving away from traditional methods such as Kjeldahl and Soxhlet, which are time-consuming, require extensive material usage, involve heavy chemical consumption, are prone to instability over time, and increase the likelihood of human error. These methods demand intensive labor, pose risks to human and environmental health, and may lead to serious long-term health issues.
Today, many reputable companies in the grain industry are transitioning to next-generation technologies based on Near-Infrared Reflectance (NIR) spectroscopy.

Differences between traditional gluten analysis methods not only impose significant economic burdens on producers but also create deviations in results that may lead to irreversible or difficult-to-correct issues in production processes. At this point, the BASTAK 9000 NIR device minimizes deviations and has a high capability to predict wheat functionality.
In today’s competitive food and agriculture industry, having high production capacity is not enough; producers must also prove product quality in a short time. The BASTAK DA (Diode Array) 9000 transforms long, complex, and error-prone laboratory processes into a fast, easy-to-use, high-precision analysis method with standardized measurement principles and a 13-inch LCD touchscreen interface.
2. Old Habits vs. NIR: Which One Moves You Forward?
2.1 Economic Losses, Penalties, and Waiting Times
In the modern flour industry, one of the most important conditions for profitability in sustainability is maintaining quality. Even small variations in quality can result in tons of defective products.
A single faulty shipment in a standard 25–30 ton truck can lead to economic losses ranging from $15,000 to $25,000. Especially in high-volume production, time must be managed efficiently. Reliable and rapid testing devices are essential in logistics.
Traditional methods such as Kjeldahl, oven drying, and manual gluten washing, although accurate, require long processing times:
- Kjeldahl method: 2–4 hours per sample
- Oven (moisture analysis): 1–2 hours + cooling time
- Manual gluten washing: 45–60 minutes
- Zeleny sedimentation test: requires shaking and long settling periods
These delays slow down laboratory workflows and increase costs. Trucks waiting for analysis results generate demurrage costs, and delays can lead to penalties, especially in maritime trade where container waiting costs are significantly higher.
The BASTAK 9000 NIR device delivers results within 30 seconds, providing critical parameters such as moisture, protein, ash, gluten, and Zeleny sedimentation quickly and accurately. This enables real-time decision-making and optimization of operational costs.
Scientific studies show that NIR systems operating within the 750–2500 nm wavelength range, combined with advanced algorithms, provide high accuracy in predicting grain quality.
Comparative analyses conducted to evaluate the performance of the Bastak NIR DA 9000 used reference values from traditional (wet chemistry) methods:
- Protein: Bastak Kjeldahl System
- Gluten: Bastak 6000 and 6100 Gluten Cheq
- Moisture: Bastak Oven
Results showed minimal deviation and high repeatability, with a correlation coefficient of 99%.
Blind Production, Profit Loss, and Energy Inefficiency
One of the biggest mistakes is adjusting machines based on outdated analysis results or operator experience. Wheat hardness and moisture vary, requiring precise adjustments.
Incorrect settings may lead to:
- Excessive pressure → bran mixing → higher ash → lower quality
- Insufficient grinding → repeated processing → up to 2x energy consumption
- Overheating → protein denaturation → poor baking performance
- Increased wear → reduced machine lifespan → higher maintenance costs
Without real-time data, even a small miscalculation (e.g., 0.5% protein difference) directly reduces profit margins.
Labor and Chemical Costs
Traditional methods require skilled labor, attention, and experience. Human error in weighing, titration, and process management affects accuracy.
Challenges include:
- Need for trained chemists/laborants
- Long training periods for new staff
- Limited daily sample capacity
- Increased workforce with higher sample volume
In contrast, the Bastak NIR DA 9000 eliminates operator-related errors and provides highly repeatable results within seconds.
Traditional methods also rely heavily on chemicals:
- High chemical costs (e.g., Kjeldahl reagents)
- Hazardous material storage requirements
- Disposal regulations requiring licensed companies
- Additional costs (filters, glassware, cleaning)
They also consume high energy due to equipment like:
- Ash furnaces (500–900°C)
- Drying ovens
- Distillation units
The Bastak NIR system only consumes power during analysis and eliminates chemical usage, significantly reducing operational risks and costs.

How Protein Analysis Performed by 9000 NIR at BASTAK ?
Introduction
Protein analysis is one of the most critical quality parameters in cereals, flour, and cereal-based products, as protein content directly affects nutritional value, processing behavior, and final product quality. Conventional protein determination methods, although reliable, are often time-consuming, labor-intensive, and require chemical reagents. In response to the increasing demand for rapid, accurate, and environmentally friendly analytical techniques, Near Infrared (NIR) spectroscopy has become a widely accepted alternative in food quality control laboratories.
BASTAK Instruments 9000 NIR Analyzer is extensively used in leading quality control laboratories worldwide for rapid determination of protein and other quality parameters in wheat and flour samples, from raw material intake to final product control.
Working Principle of NIR Spectroscopy
Near Infrared (NIR) spectroscopy is based on the absorption of electromagnetic radiation in the wavelength range of 780–2500 nm (corresponding to 4000–13,000 cm⁻¹). When NIR radiation interacts with a sample, specific chemical bonds absorb energy and undergo vibrational transitions.
In organic molecules, NIR absorption bands mainly arise from overtones and combination vibrations of fundamental molecular bonds such as –CH, –NH, and –OH. These absorption bands often overlap, creating complex spectra that reflect the overall chemical composition of the sample. By applying multivariate calibration models, these spectral patterns can be correlated with reference chemical values such as protein content.
Spectroscopic analysis, in general, relies on measuring and interpreting electromagnetic radiation absorbed or emitted as a result of molecular rotation, vibration, and electronic excitation. Among spectroscopic techniques used in food analysis, infrared spectroscopy and particularly NIR spectroscopy stands out due to its speed, non-destructive nature, and minimal sample preparation requirements.

BASTAK 9000 NIR Technology
BASTAK 9000 NIR Instruments operate on advanced near-infrared transformation principles and are designed for routine quality control applications. Thanks to BASTAK’s superior and robust NIR technology, the DA 9000 enables simultaneous and rapid measurement of multiple quality parameters within seconds.
Using this system, the following parameters can be determined in red bread wheat, white bread wheat, durum wheat, and flour samples:
- Protein content
- Gluten content
- Moisture content
- Ash content
- Zeleny sedimentation value
9000 NIR provides reliable results without the use of chemicals or reagents, making it an environmentally friendly (“green”) analytical solution suitable for high-throughput industrial laboratories.
Protein and Gluten Determination: Reference Methods
For calibration and validation purposes, conventional reference methods are still used. Total protein content is commonly determined by the Kjeldahl method in accordance with ISO 20483:2006, which measures total nitrogen and converts it to protein using a conversion factor. Gluten quality is traditionally evaluated by determining wet gluten using standardized mechanical methods (ISO, 2006).

Importance of Protein Analysis in Wheat Flour
Wheat flour is a key ingredient in a wide range of food products, including bread, cakes, biscuits, crackers, pasta, and noodles. Flour quality is generally characterized by parameters such as total protein, gluten quality, amylose, and amylopectin content. Among these, total protein and wet gluten content play decisive roles in determining dough rheology, processing suitability, and final product performance.
Accurate and rapid determination of these parameters allows manufacturers to:
- Select the appropriate flour for specific product formulations
- Optimize processing conditions
- Ensure consistent product quality
Given the limitations of conventional methods, NIR spectroscopy implemented through instruments such as the BASTAK 9000 NIR provides a practical and efficient solution for modern flour and cereal analysis laboratories.
NIR-based protein analysis offers several advantages:
- Rapid analysis (results within seconds)
- No chemical reagents required
- Minimal or no sample preparation
- Non-destructive measurement
- Reduced operational costs and environmental impact
Studies have shown that NIR spectroscopy provides reliable protein predictions when properly calibrated against reference methods, making it suitable for routine quality control applications.
Nutrition Duel: Quinoa or Bulgur?
Nutrition Duel: Quinoa or Bulgur?
Nowadays, interest in healthy nutrition and various food alternatives is increasing. In this context, quinoa, which has gained popularity in recent years, has become widespread among healthy life enthusiasts. So, can quinoa really be considered an alternative to bulgur? Which food is healthier? We will evaluate these two foods by comparing them in detail.
Quinoa originates from South America and is a food that has been consumed for thousands of years. Quinoa, one of the staple foods of the Inca Empire, is not actually a grain. They are the seeds of a broad-leafed plant from the Chenopodiaceae family. It is classified as pseudo-cereal because its nutritional content is similar to grains. Quinoa attracts attention with its resistance to climatic conditions and high nutritional value. For this reason, 2013 was declared the International Year of Quinoa by the United Nations.
Bulgur, on the other hand, is a semi-cooked food obtained as a result of whole wheat grains going through the stages of boiling, drying, crushing and grinding. Bulgur, which has been in our kitchens for many years, is both a nutritious and economical food.
If we compare the nutritional properties of quinoa and bulgur:
The calorie content of quinoa and bulgur is similar; However, bulgur has lower calorie content. One small bowl of cooked quinoa contains 222 calories, while the same amount of bulgur contains 122 calories. The protein content of quinoa is higher than bulgur.To accurately measure protein, moisture, and fat levels in grains like quinoa and bulgur, laboratories often use advanced NIR analyzers . Quinoa is an important food source, especially for vegans and vegetarians, with its high protein and quality amino acid content.
The fat content of quinoa is higher than bulgur. While 100 grams of bulgur contains 2 grams of fat, the same amount of quinoa contains 6.7 grams of fat. Quinoa is especially rich in linoleic and linolenic unsaturated fatty acids. In terms of fiber content, quinoa has a higher fiber content than other grains except buckwheat. Since quinoa is rich in dietary fiber, it supports the digestive system and contributes to blood sugar management. Bulgur has lower fiber content than quinoa, but still contributes to your daily fiber intake.
Quinoa is rich in carotene, a derivative of vitamin A, vitamin E and B group vitamins. It is also superior to many grains in terms of iron, magnesium, potassium and zinc minerals. Bulgur is especially rich in B vitamins such as niacin, thiamine and riboflavin. Niacin is important for the nervous and digestive systems and bulgur is a rich source of this vitamin.
Evaluating the glycemic index and satiety duration of quinoa and bulgur; Quinoa and bulgur have low glycemic indexes. Thanks to these properties, they do not cause sudden increases in blood sugar and keep you full for a long time. However, quinoa does not absorb as much water as bulgur during cooking, so the feeling of fullness may last longer when bulgur is consumed NILELITRE 7500 plays a key role in grain cooking, storage stability, and overall quality.
Quinoa does not contain gluten and is therefore an ideal food for celiac patients and people with gluten sensitivity. Bulgur contains gluten and therefore should not be consumed by celiac patients.
Quinoa contains high amounts of phytic acid and oxalates. Phytic acid reduces the absorption of minerals such as iron and zinc, while oxalates can cause problems for people prone to kidney stone formation. Therefore, soaking quinoa in water before consuming it is an effective method to reduce the amount of phytic acid.
Quinoa is just beginning to appear in kitchens and can be used in all dishes where bulgur is used. After the shells are removed, they can be used in dishes such as pilaf, barley, stuffed vegetables and stuffed vegetables. Additionally, pasta, pancakes, bread, biscuits, cakes and crackers can be made with quinoa flour.Before processing, grains such as quinoa and bulgur must be thoroughly SAMPLER CLEANER 13500 to remove dust and impurities. For accurate nutritional testing, grain samples are usually CRUSHING MILL 1600 Bulgur production also begins with wheat ROLLER MILL 4000 and controlled processing.
Quinoa and bulgur are both nutritious and healthy options. Both foods are rich in protein, vitamins, minerals and dietary fiber and can be part of a healthy diet when consumed in a balanced manner. You can occasionally choose bulgur or quinoa instead of white rice to increase the vitamin, mineral and dietary fiber content of your diet. Especially for people with gluten sensitivity, quinoa is an excellent alternative to bulgur.
For example, you can get more fiber, healthy fatty acids and iron minerals by using quinoa instead of bulgur or rice when making stuffed zucchini. How about trying your stuffed vegetables, pilafs and wraps with quinoa or bulgur?
Enjoy the Taste of Pizza on World Pizza Day
Join the Flavor Feast!
Pizza, prepared with crispy yeast dough and baked in the oven, was traditionally covered with tomato sauce, mozzarella cheese, and various toppings in the old days. However, nowadays, pizza has become a platform that pushes the boundaries of creativity. It can be topped with various savory ingredients, including sauces, meats, vegetables, and cheeses.
As seen, many people may perceive pizza as a low-nutrient food when they choose it. However, published data often show the opposite to be true. In fact, most pizzas are quite high in nutritional value. Serving as a good source of protein, pizza is also rich in complex carbohydrates, vitamins, and minerals.
Quality Control in Pizza Dough!
The pizza industry is a significant sector worldwide, hence there are many top ingredients that vary from country to country. Pizza is generally a flat tart made from bread dough. Pizza dough can be prepared chemically leavened or yeast-leavened. Flour is a basic ingredient in bakery products production, and there are various types of flour with different protein levels and qualities.
Flour Quality and Protein Content
Pizza dough undergoes a process of freezing, storing, and thawing. Therefore, it's important for the flour used in frozen dough to have good strength and high protein content. Hard wheat varieties of flour with a protein content of 11-14% are often preferred for frozen dough products. Determine the protein property of pizza flour with the latest technology DA 9000 NIR device in less than 1 minute!
Global Consumption and Dough Composition
Traditionally consumed in European countries, especially Italy, pizza has commercial appeal in Latin American countries and the United States. This interest is based on reasons such as the low cost of the product and its ease of preparation for consumption. The basic formulation of pizza dough includes flour, water, salt, sugar, and yeast. Dough constitutes a large part of the product, and its appearance, texture, and taste are important characteristics for consumer acceptance and recognition. Therefore, dough quality is crucial as wheat flour, a structural component, and a basic ingredient play an important role in the quality of cooked foods.
Dough Processing and Fermentation
Processing steps responsible for increasing the volume of dough and trapping gas include mixing and shaping the dough, dividing and shaping it, fermentation, stretching, and baking. Fermentation allows the dough to aerate; this occurs through the production of carbon dioxide in the aqueous phase of the dough and the formation of excess internal pressure forcing expansion in the alveoli. The stabilization of alveoli determines the structure and volume of the dough.
Fermentation Conditions and Gluten Properties
The dough is typically fermented at temperatures between 23 and 26 °C with baker's yeast until its initial volume increases 2-5 times or until the fermentation process. Despite most pizza dough production methods being similar, the lack of standardization reflects on parameters such as the appearance, height, texture, and other quality aspects of the final product. Achieving the appearance, consistency, taste, and consistency of the final product requires understanding gluten properties used in pizza dough. It is critical to determine gluten content of the flour used in crepe production for the purpose of identifying viscoelastic properties, baking behavior, and physical quality characteristics.
Desired Characteristics of Pizza Dough
The edges of the pizza should be puffed up and gently browned. The dough should contain various sizes of pores so that the pizza has a light and tasty texture. The pizza dough should not be overly thick or too thin and crispy. For Quality Control in Pizza Dough, meet with Bastak Reology System Absograph 500 & Resistograph 500!
