In the intriguing world of tobacco, Cut Rolled Expanded Stems stand as a testament to innovation, skill, and craftsmanship. But what makes them so special? Why are they considered the future of tobacco?
Cut Rolled Expanded Stems (CRES) are rolled, flattened, and shredded tobacco leaf stems that are expanded by being soaked in water and rapidly heated and then dried. They can be used in cigarette production with no adverse effect in terms of taste or general blend characteristics. Expanded Stems can also be used as a means for reducing standard ISO tar and nicotine yields.
Filling capacity is an important physical characteristic for evaluating CRES quality and for designing cigarettes. A study was conducted to establish a calibration model to estimate the filling capacity of CRES from Vis-NIR spectrum of the stem. After 47 single-grade stem samples were ground, they were measured using Vis-NIR spectroscopy. The filling capacity of CRES produced from each stem sample was measured using a conventional method. The obtained values were indexed, with 100 representing the filling capacity of a certain grade. A calibration model was developed, showing that absorption around 670 nm and 2360 nm had an important role in the model.
Cut Rolled Expanded Stems: An Overview
Cut rolled expanded stems (CRES) are a fascinating and integral part of the tobacco industry, playing a significant role in cigarette production. These stems are rolled, flattened, and shredded tobacco leaf stems that are expanded through a process involving water soaking, rapid heating, and drying.
Understanding Cut Rolled Expanded Stems
These expanded stems are unique in that they can be used up to a certain percentage in cigarette production without adversely affecting the taste or general blend characteristics of the cigarette. This makes them a crucial ingredient in the tobacco blending process.
The Process of Producing Cut Rolled Expanded Stems
The production of CRES involves a specific process. After the tobacco leaf stems are rolled and flattened, they undergo a rapid heating and drying process. This results in the expansion of the stems, thus giving them their unique physical characteristics.
The Role of Cut Rolled Expanded Stems in Cigarette Production
Filling Capacity: A Key Quality Measure for Cut Rolled Expanded Stems
One important physical characteristic of CRES is their filling capacity. This attribute is significant when evaluating the quality of CRES and is crucial for the design of cigarettes. In other words, the filling capacity of CRES can impact the overall performance and characteristics of a cigarette.
The Impact of Cut Rolled Expanded Stems on Cigarette Design
CRES contribute to the overall design and functionality of cigarettes. By using CRES in the blend, manufacturers can manipulate the characteristics of the cigarette to meet certain requirements and standards, without compromising on the taste or general blend characteristics.
Technological Advancements in Cut Rolled Expanded Stems
Estimating Filling Capacity: From Manual to Machine Learning
Recent studies have focused on establishing calibration models to estimate the filling capacity of CRES from the visible-near infrared (Vis-NIR) spectrum of the stem. This technological advancement provides an economical and cost-effective approach to estimating the filling capacity of CRES, replacing inefficient pre-production trials with a practical, rapid, and low-cost method.
The Role of Vis-NIR Spectroscopy in Quality Assessment
Vis-NIR spectroscopy has emerged as a crucial tool in the quality assessment of CRES. By analyzing the Vis-NIR spectrum of the stem, researchers can estimate the filling capacity of CRES, which is a significant measure of their quality. The calibration model developed for this purpose has been found to be a useful and rapid evaluation tool for filling capacity estimation and for subsequent CRES blending assessment.
The Future of Cut Rolled Expanded Stems Production: Innovation and Efficiency
With technological advancements like Vis-NIR spectroscopy, the production and quality assessment of CRES are expected to become more efficient and accurate. This will not only improve the quality of CRES but also increase the efficiency of cigarette production, paving the way for further innovation in the tobacco industry.

As the tobacco industry continues to evolve, the role of CRES is expected to become even more significant, further shaping the future of cigarette production and design.
Statistics:
When comparing different types of expanded stem materials in cigarettes, it was found that cigarettes containing expanded shredded stem (ESS) delivered more tar, nicotine, and phenol, and less CO and HCN than cigarettes containing expanded cut stem (ECS) or CRES. When the proportion of stem material in the cigarette blend was 20%, the deliveries of tar, nicotine, and phenol in the smoke of ESS cigarette increased by 6.3%, 11.2%, and 10.8%, while the deliveries of CO and HCN reduced by 11.6% and 3.4%, respectively, compared with ECS cigarette.
