Public policies and Canadian ethanol production: history and future prospects for an emerging industry

ABSTRACTThe Canadian ethanol industry has grown rapidly and is approaching a crossroads. Government funding has played a role in increasing domestic ethanol production, but the future of such funding is uncertain. Government renewable fuel mandates have helped create a demand for ethanol, but domestic production will soon achieve the mandates. Therefore, the Canadian ethanol industry finds itself in a situation where current policies have largely been played out, and within a global market where large established players dominate market share. Within this context, the future prospects for Canadian ethanol are highly uncertain, being dependent on public policies, the future price of oil, and technological progress that could tilt production towards second-generation feedstock, where Canada may have a comparative advantage.

Biofuel and Advanced Biofuel

A. Ethanol From Cellulose Cellulosic ethanol is the most promising second-generation biofuel, but the cost of production limits its viability, though costs are declining. (203) In order to qualify for a renewable identification number for cellulosic ethanol, production must meet requirements include lifecycle greenhouse gas emissions, as determined by the Administrator, that are at least 60 percent less than the baseline lifecycle greenhouse gas (GHG) emissions from gasoline or diesel, whichever the fuel is replacing. (204) In June 2012, the first tradable renewable identification number was issued to Blue Sugars for cellulosic ethanol production, but the company went bankrupt in 2013. (205) The CAA requires 0.1 billion gallons of cellulosic biofuel to be used in the year 2010 and its use to increase in steps to 16.0 billion gallons in 2022. (206) The administrator of EPA is given limited power in CAA section 211(o)(4) to modify the advanced biofuel and cellulosic requirements concerning the mandated percentages of GHG reductions. Section 211(o)(7)(A) allows the Administrator to modify the utilization requirements to prevent harm to the economy, the environment, or because of inadequate production. (207) This power has been used to adjust production requirements; in 2012, the industry produced only 20,069 gallons of fuel. (208) An alternative approach proposed by EPA to deal with the industry's performance is to change the definition of cellulosic ethanol to allow more fuels to qualify as cellulosic biofuels. (209) Technical amendments to the RFS to clarify the number of cellulosic biofuel identification numbers for fuels of varying cellulosic content were promulgated on July 8, 2014. (210) Ethanol produced from cellulose or other non-food inputs is a promising source of biofuels. It can be produced from trees and forest residues, although there is no commercial production of fuel from woody biomass except for the use of pulp and saw mill wastes to produce heat, steam, and electricity. (211) Fast growing woody crops such as hybrid willow and poplar have the potential to be feedstock for cellulosic fuel. (212) Another potential feedstock is perennial grass, such as switchgrass or Giant Miscanthus. Switchgrass is a perennial Midwest and Southeast grass with nearly three times the yield of hay. Giant Miscanthus is a native of Asia has some use as a fuel in Europe. The advantage of perennial grasses is they are not normally irrigated and therefore require less water, fertilizer, and pesticides than most crops, and their extensive root system reduces soil erosion and provides habitat for wildlife. (213) Some of the plants approved for renewable fuel production by EPA, such as giant reed and napier grass, are invasive species other government agencies are trying to control. (214) Agricultural residues not specifically grown for food such as corn stover can be used to produce cellulosic ethanol, although the use of corn stover for fuel could lead to increases in soil erosion. (215) A 2007 lifecycle study found the energy requirements for cellulosic fuel production are low for switchgrass and hybrid poplar feedstock when compared to corn crops. Other experts claim cellulosic ethanol has a 100 percent energy gain, compared to the 34 percent energy gain for corn. (216) Utilizing non-food inputs is important because if all of the United States corn harvest is devoted to ethanol production it would offset about 25 percent of national gasoline demand. (217) An advantage of using cellulosic feedstock is it can be grown on marginal or degraded land can provide increased regional agricultural income without utilizing land used for food production. (218) Moreover, cellulosic feedstocks require less pesticides and fertilizer than corn-based ethanol. (219) However, demand for cellulosic ethanol could result in adverse impacts on forests if they were cut to produce fuel or converted to plantations of fast growing trees. …

Enhanced ethanol production via electrostatically accelerated fermentation of glucose using Saccharomyces cerevisiae.

The global demand for ethanol as an alternative fuel continues to rise. Advancement in all aspects of ethanol production is deemed beneficial to the ethanol industry. Traditional fermentation requires 50–70 hours to produce the maximum ethanol concentration of 7–8% (v/v). Here we demonstrate an electrostatic fermentation method that is capable of accelerating the fermentation of glucose using generic Saccharomyces cerevisiae as the fermenting microorganism to produce ethanol. The method, when applied to the batch fermentation of 1 liter fermenting mixture containing dry yeast without pre-culture, is able to achieve ethanol yield on the high gravity level (12.3% v/v) in 24 hours. The fermentation results in almost complete consumption of glucose. With pre-cultured yeast, ethanol yield can reach 14% v/v in 20 hours. The scale-up capability of the method is demonstrated with 2 liter fermenting mixture. The method does not consume external energy due to its electrostatic nature. Our results indicate the applicability of the fermentation technique to industry applications.

Overview on Mechanical-Chemical Ionic Liquid Pretreatment Study on Bioethanol–Based Lignocellulosics Biomass

Due to rapid growth in population and industrialization, worldwide ethanol demand is increasing continuously. The abundant sources of lignocellulosic biomass (LB) from agricultural wastes are attractive feed stocks to become a sustainable source for bioethanol production. There are many crucial engineering steps involved in the bioethanol production route especially on the pretreatment which comprises of chemical, mechanical and biological approaches. In this study we reviewed the various pretreatment involved in biofuel production. By considering the all steps required which may incur costs then influence the price of bioethanol an effective pretreatment technology is required for minimizing the cost and concurrently minimizing other problem especially environmental pollution caused by the pretreatment process. Therefore, a compact step combining all or some of the steps and with additional application of green technology with ionic liquid (IL) will be beneficial to the future direct production of liquefied biofuel with chemical-mechanical-biological based techniques starting from the pretreatment study which therefore lessen cost incurred and process time.

An Approach to Identify the Suitable Plant Location for Miscanthus-Based Ethanol Industry: A Case Study in Ontario, Canada

The life cycle (LC) of ethanol extracted from Miscanthus has been evaluated to identify the potential location for the Miscanthus-based ethanol industry in Ontario, Canada to mitigate greenhouse gas (GHG) emissions and minimize the production cost of ethanol. Four scenarios are established considering the land classes, land use, and cropping patterns in Ontario, Canada. The net energy consumption, emissions, and cost of ethanol are observed to be dependent on the processing plant location and scenarios. The net energy consumption, emissions, and cost vary from 12.9 MJ/L to 13.4 MJ/L, 0.79 $/L to 0.84 $/L, and 0.45 kg-CO2e/L to 1.32 kg-CO2e/L, respectively, which are reliant on the scenarios. Eastern Ontario has emerged as the best option. This study reveals that Miscanthus is a potential feedstock for the ethanol industries in Ontario, even if it is cultivated on marginal land. This study also highlights the contribution of energy crops (Miscanthus) to avoid the potential technical and economic constraints of lignocellulosic biomass for the renewable energy industry. Miscanthus may help avoid competition with food crops for prime land (higher quality land that is suitable for food crops), avoid the food versus fuel debate, help meet the ethanol demand, and achieve the GHG emissions abatement target of Canada.

Exploring the policy and social factors fueling the expansion and shift of sugarcane production in the Brazilian Cerrado

Within the past decade, the sugarcane ethanol industry in Brazil has increased its production capacity to meet rising domestic demand for ethanol. However, to achieve this growth the industry has had to expand into new frontiers in the Brazilian Cerrado, specifically in the states of Goias and Mato Grosso do Sul, which is now the second largest producing area of ethanol in Brazil. We argue that the expansion into the Brazilian Cerrado is a result of the interactions between the increase in demand, governmental policies, infrastructure, and factors that have prevented traditional sugarcane producing regions from meeting the increasing demand for ethanol. This paper analyzes the policies that have shaped the sugarcane industry in Brazil and the expansion of the industry across the country. The policies and issues examined include those that led to the concentration and consolidation of the sugarcane industry in the state of Sao Paulo and the consequences of this consolidation; the influence of governmental policies on the decision-making process of producers and industry; the state-level policies designed to expand the industry into Goias and Mato Grosso do Sul states; infrastructure development; and the Sugarcane Agroecological Zoning policies. Through this study we conclude that the ethanol industry identified the Cerrado states as an opportunity for investment, given the good agricultural conditions for producing sugarcane, affordable land prices and favorable state-level fiscal incentive policies. In addition, there is a need for further regional development policies as the interaction between the sugarcane sector and regional government is likely to continue into the future.

Hybrid Input‐Output Life Cycle Assessment of First‐ and Second‐Generation Ethanol Production Technologies in Brazil

SummaryA hybrid approach combining life cycle assessment and input‐output analysis was used to demonstrate the economic and environmental benefits of current and future improvements in agricultural and industrial technologies for ethanol production in Brazilian biorefineries. In this article, three main scenarios were evaluated: first‐generation ethanol production with the average current technology; the improved current technology; and the integration of improved first‐ and second‐generation ethanol production. For the improved first‐generation scenario, a US$1 million increase in ethanol demand can give rise to US$2.5 million of total economic activity in the Brazilian economy when direct and indirect purchases of inputs are considered. This value is slightly higher than the economic activity (US$1.8 million) for an energy equivalent amount of gasoline. The integration of first‐ and second‐generation technologies significantly reduces the total greenhouse gas emissions of ethanol production: 14.6 versus 86.4 grams of carbon dioxide equivalent per megajoule (g CO2‐eq/MJ) for gasoline. Moreover, emissions of ethanol can be negative (–10.5 g CO2‐eq/MJ) when the system boundary is expanded to account for surplus bioelectricity by displacement of natural gas thermal electricity generation considering electricity produced in first‐generation optimized biorefineries.

Estimation of cumulative energy demand and green house gas emissions of ethanol foamed WMA using life cycle assessment analysis

The purpose of this project is to evaluate the possibility of using ethanol as a foaming agent for low emission asphalt technology via life cycle assessment (LCA) analysis. LCA analysis was conducted at two different stages. Firstly, the analysis was performed to estimate the energy consumption and CO2 emission in the cradle to gate stages incorporating the effects of various foaming agent contents. In the second assessment, the analysis attempts to incorporate the required information based on the available published papers to get a clear idea about the energy consumption and GHG emission involved in all stages from the raw materials production to the end of life of asphalt pavement. The scope and boundaries of this analysis have been set based on several assumptions made prior to performing the analysis. LCA software, SimaPro 7.3, was used to estimate the cumulative energy demand and global warming potential (GWP) of Ethanol-foamed Warm Mix Asphalt (EWMA) and compare these to the results of Hot Mix Asphalt (HMA) and Water-foamed Warm Mix Asphalt (WWMA). Eco-Indicator 95 analysis was also conducted to establish the weighting factors for the various environmental effects of each asphalt mixture. Based on the results, it was found that the EWMA performed better in terms of energy demand, and lowered GHG emissions compared to HMA and WWMA. EWMA has high potential to reduce the detrimental impacts from the asphalt pavement industry based on Eco-Indicator 95 analysis, which has a lower impact in terms of GHG emissions, ozone layer depletion, acidification, eutrophication, summer smog, and winter smog, as well as energy resources.

Distributional Effects of Selected Farm and Food Policies: The Effects of Crop Insurance, Snap, and Ethanol Promotion

This paper investigates the influence of three federal policies often conjectured to have some of the most pronounced effects on food markets: subsidized crop insurance; the Supplemental Nutrition Assistance Program (SNAP); and ethanol promotion. Results indicate that removing subsidized crop insurance would yield economic benefits of $932 million per year. Removing crop insurance would reduce producer and consumer surplus, with taxpayers being the only aggregate beneficiaries, suggesting that the costs are hidden in the form of a higher tax burden. Agricultural producers in several western states would benefit from the removal of crop insurance subsidies, whereas producers in the Great Plains states would be the biggest losers. Depending on how SNAP recipients spend their disbursements, the projected benefits of dismantling SNAP range from $12.7 billion to $42.8 billion per year. Reducing ethanol demand is projected to benefit livestock producers and food consumers while harming corn producers.

Adding sweet sorghum juice into current dry-grind ethanol process for improving ethanol yields and water efficiency.

Sweet sorghum is a promising energy crop due to its low fertilizer and water requirements, short growth period, and high biomass yield. However, the challenge for sweet sorghum as a feedstock for ethanol production is its short harvest period and the extreme instability of its juice, both of which make achieving a year-round production process difficult. One way to solve this challenge and to meet the growing demand of bio-renewable ethanol is to incorporate sweet sorghum juice into the current dry-grind ethanol process. In the dry-grind process, the whole grain kernel is milled and fermented to produce ethanol. In this study, sweet sorghum juice with varying grain sorghum flour contents was liquefied, saccharified, fermented, and distilled to produce ethanol. Ethanol yield from sweet sorghum juice with the optimum grain sorghum flour loading was about 28% higher than that from the conventional ethanol process. Enzymatic hydrolysis with this process could be reduced by 30 min. The fermentation performance of sweet sorghum juice with grain flour using a raw starch hydrolyzing enzyme was also investigated, and ethanol yield was about 21% higher than that from the conventional process. This innovative technology enabling ethanol production from sweet sorghum juice could improve ethanol yield, save energy, and significantly decrease water use in the current dry-grind ethanol process.

Food Grade Ehanol Production With Fermentation And Distillation Process Using Stem Sorghum

10% -12% of sugar in its stem which is the optimum sugar concentration in fermentation process for bioethanol production. Sorghum has a high potential to be developed as a raw material for food-grade ethanol production which can be used to support food-grade ethanol demand in Indonesia through a fermentation process. This research focused on the effect of microorganism varieties in the fermentation process which are mutant Zymomonas mobilis (A3), Saccharomyces cerevisiae and Pichia stipitis mixture. The Research for purification process are separated into two parts, distillation with steel wool structured packing and dehydration process using molecular sieve and eliminating impurities using activated carbon. The research can be concluded that the best productivity shown in continuous fermentation in the amount of 84.049 (g / L.hr) using the mixture of Saccharomyces cerevisiae and Pichia stipitis. The highest percentage of ethanol yield produced in batch fermentation using the mixture of Saccharomyces cerevisiae and Pichia stipitis that is equal to 51.269%. And for the adsorption, the best result shown in continuous fermentation by using Zymomonas Mobilis of 88.374%..

Assessing the importance of the riparian zone for stream fish communities in a sugarcane dominated landscape (Piracicaba River Basin, Southeast Brazil)

In the Neotropics, the effect of agriculture on freshwater habitats is still poorly understood, particularly with respect to sugarcane expansion to meet increased ethanol demands. The variation in taxonomic composition, community attributes and trophic structure of fish assemblages from streams under different riparian zone preservation conditions were studied. Nine stream reaches under the following riparian vegetation conditions were selected: Native Forest (NF), with mostly primary forest; Secondary Forest (SF), which included sites with vegetation in an advanced stage of regeneration surrounded by sugarcane plantations; and Sugarcane sites (SC), located in areas without riparian vegetation, adjacent to sugarcane crops. Forty-one species were collected. The variance partitioning and partial Redundancy Analysis (pRDA) indicated that community composition and trophic structure were significantly explained by riparian condition and spatial variations, while diversity, richness, abundance and biomass were only explained by season and space, with higher diversity and richness at the SF sites. Abundance-Biomass curves (ABC curves) suggested that sugarcane plantations destabilized fish assemblages, especially at the more intensively managed sites, which seem to influence stream integrity and associated fish fauna. We concluded that both physical conditions of streams and some attributes of fish communities reflected the different levels of preservation of the riparian buffers, but given the influence of regional processes which have a pervasive role in shaping local assemblages, land use at the watershed scale seemed to be important especially to explain the higher richness and diversity found at the SF sites.

Soil carbon, nitrogen and phosphorus changes under sugarcane expansion in Brazil

Historical data of land use change (LUC) indicated that the sugarcane expansion has mainly displaced pasture areas in Central–Southern Brazil, globally the largest producer, and that those pastures were prior established over native forests in the Cerrado biome. We sampled 3 chronosequences of land use comprising native vegetation (NV), pasture (PA), and sugarcane crop (SC) in the sugarcane expansion region to assess the effects of LUC on soil carbon, nitrogen, and labile phosphorus pools. Thirty years after conversion of NV to PA, we found significant losses of original soil organic matter (SOM) from NV, while insufficient new organic matter was introduced from tropical grasses into soil to offset the losses, reflecting in a net C emission of 0.4Mgha−1yr−1. These findings added to decreases in 15N signal indicated that labile portions of SOM are preserved under PA. Afterwards, in the firsts five years after LUC from PA to SC, sparse variations were found in SOM levels. After more than 20years of sugarcane crop, however, there were losses of 40 and 35% of C and N stocks, respectively, resulting in a rate of C emission of 1.3Mgha−1yr−1 totally caused by the respiration of SOM from C4-cycle plants. In addition, conversion of pastures to sugarcane mostly increased 15N signal, indicating an accumulation of more recalcitrant SOM under sugarcane. The microbe- and plant-available P showed site-specific responses to LUC as a function of different P-input managements, with the biological pool mostly accounting for more than 50% of the labile P in both anthropic land uses. With the projections of 6.4Mha of land required by 2021 for sugarcane expansion in Brazil to achieve ethanol's demand, this explanatory approach to the responses of SOM to LUC will contribute for an accurate assessment of the CO2 balance of sugarcane ethanol.

EXPANSÃO DA CANA-DE-AÇÚCAR NA MICRORREGIÃO SUDOESTE DE GOIÁS: ANÁLISE ESPACIAL DAS MUDANÇAS DO USO E COBERTURA DO SOLO NOS ANOS DE 2001, 2006 E 2011

The worldwide interest in reducing dependence on fossil fuels and diversify the energy matrix to mitigate global warming, has attracted attention to bio fuels, especially ethanol from sugar cane, which promoting strongly expansion of sugar cane cultivation area and increase of number of mills, concentrated on Cerrado region, particularly on Goiás and Mato Grosso do Sul states. To face the growing demand for ethanol it is necessary to increase the production of sugar cane as much as the increase of the cultivated area as well as increasing the productivity. The southwestern Goiás (SW) is dominated by agribusiness, especially for meat - grains chain activities which, during the last decades, were practically absolute in defining the spatial dynamics in this region. The objective was to analyze the conversion of the use and land occupation for sugar cane in the SW of Goiás, in the years 2001, 2006 and 2011. Of all the area cultivated with sugarcane in the region in 2011, 55%, 28% and 17% occurred in areas where, in 2006, were occupied with agriculture activity, grassland and savanna, respectively. Thus, the areas of agriculture represent more than half of all the areas replaced by sugar cane SW of Goiás in 2011, showing a preference for agricultural areas, due to agronomic advantages compared to grazingareas.Key words: sugar cane, crop substitution, remote sensing, southwest of Goiás.

Performance evaluation for Bioethanol production in three reactors: Batch, packed bed and Fluidized bed bio-reactors

Ethanol demand has continued to grow, both as an alternative fuel and as a petroleum fuel extender because of gasoline shortages. Ethanol production from renewable carbohydrate materials has attracted worldwide interest, and much research has focused on ethanol production using immobilized viable microbial cells in continuous systems. Biochemical pathway, the main reactor used for fermentation is classical well-mixed reactor need to be improved to the continuous reactor to reduce the operation cost, product inhibition and wash out. Immobilized biomass (Saccharomyces cerevisiae) activity has been given more attention, since it has been acknowledged to play a significant role in bioreactor performance. An attempt has been made to compare the production of bioethanol in batch, packed, fluidized bed bio-reactors. Present study, focused mainly sodium alginate (2% to 6%) as micro-organism support for production of bio-ethanol in all three reactors and find the better reactor and better concentration of sodium alginate for immobilization of yeast.

Experiences, situation and prospects of biofuels production in India

Inspite of several efforts and policies by the state on biofuels, the progress of biofuels has not been significant so far. Thus, biodiesel has been not developed though there were some areas where ethanol production has been growing steadily being related to sugarcane plants. This paper review the biofuel situation, feed stocks condition and the prospects of biofuel production in India. Though, several states have been promoting Jatropha but eventually in the coming years, the grower farmers were not motivated by it. Majority of the farmers has uprooted and replaced Jatropha with other agricultural crops. Also, since Jatropha required several processes in order to convert into biodiesel oil, some industry would prefer to rely on hassle free imported biofuels such as palm oil in place of Jatropha. The high competition of ethanol against potable alcohol needs a clear and strong strategy to increase the ethanol demand. Also, several studies of the state had shown that some were quite promising while some were not that worth mentioning. Therefore, doubt still arises if the programmes should continue on a large scale.

Land cover change from cotton to corn in the USA relieves freshwater ecotoxicity impact but may aggravate other regional environmental impacts

Purpose Rising corn prices in the USA due partly to increasing ethanol demands have led to a significant expansion of corn areas displacing natural vegetation and crops including cotton. From 2005 to 2009, cotton area harvested in the USA nearly halved with a reduction of 2.5 million hectares, while that of corn increased by 1.8 million hectares. However, environmental impacts of land shifts from cotton and corn have been largely neglected in literature.

The impact of biofuel demand on agricultural commodity prices: a systematic review

By diverting agricultural land away from food, feed, and livestock production, increased production of biofuel feedstock crops tend to drive up prices for agricultural commodities. But by how much? This question has been heavily debated in recent years, following the food price crisis of 2007–2008. A systematic review of 121 studies that quantifies the impact of biofuel demand on agricultural commodity markets reveals that there is still considerable uncertainty around the exact magnitude of the price response. Increased demand for corn ethanol in the United States—the focus of the majority of studies—is estimated to have accounted for 14–43% of the rise in US corn prices in the period 2000–2008. The divergence in results between studies is mainly due to different assumptions regarding demand and supply elasticities for agricultural commodities, and there is very limited empirical evidence that can help reduce the uncertainty around the value of these parameters, especially outside the United States. Few studies analyze the impact of biofuel demand beyond current or near‐future levels and it is argued that estimated price effects can neither be extrapolated to large‐scale biofuel demand shocks, nor are most models able to capture accurately the impacts of such shocks due to weaknesses in how land markets and land transformation process are modeled. To better gauge current and future impacts of biofuel demand on agricultural commodity markets, we need better data on supply and demand responses, both in the short and long run, as well as improved modeling of land competition and land‐use change.

Predicted avian responses to bioenergy development scenarios in an intensive agricultural landscape

AbstractConversion of native prairie to agriculture has increased food and bioenergy production but decreased wildlife habitat. However, enrollment of highly erodible cropland in conservation programs has compensated for some grassland loss. In the future, climate change and production of second‐generation perennial biofuel crops could further transform agricultural landscapes and increase or decrease grassland area. Switchgrass (Panicum virgatum) is an alternative biofuel feedstock that may be economically and environmentally superior to maize (Zea mays) grain for ethanol production on marginally productive lands. Switchgrass could benefit farmers economically and increase grassland area, but there is uncertainty as to how conversions between rowcrops, switchgrass monocultures and conservation grasslands might occur and affect wildlife. To explore potential impacts on grassland birds, we developed four agricultural land‐use change scenarios for an intensively cultivated landscape, each driven by potential future climatic changes and ensuing irrigation limitations, ethanol demand, commodity prices, and continuation of a conservation program. For each scenario, we calculated changes in area for landcover classes and predicted changes in grassland bird abundances. Overall, birds responded positively to the replacement of rowcrops with switchgrass and negatively to the conversion of conservation grasslands to switchgrass or rowcrops. Landscape context and interactions between climate, crop water use, and irrigation availability could influence future land‐use, and subsequently, avian habitat quality and quantity. Switchgrass is likely to provide higher quality avian habitat than rowcrops but lower quality habitat than conservation grasslands, and therefore, may most benefit birds in heavily cultivated, irrigation dependent landscapes under warmer and drier conditions, where economic profitability may also encourage conversions to drought tolerant bioenergy feedstocks.

Authentication of dried distilled grain with solubles (DDGS) by fatty acid and volatile profiling

Demand for ethanol substituted fuels from the utilisation of cereal based biofuel has resulted in an over production of dried distillers grains with solubles (DDGS) that are now readily available on the animal feed market. With this rapid emerging availability comes potential variability in the nutritional value of DDGS and possible risks of feed contaminants. Subsequently, the authentication and traceability of alternative animal feed sources is of high priority. In this study and as part of the EU research project “Quality and Safety of Feeds and Food for Europe (QSAFFE FP7-KBBE-2010-4) an attempt was made to classify the geographical origin of cereal grains used in the production of DDGS material. DDGS material of wheat and corn origin were obtained from Europe, China, and the USA. Fatty acid profiles and volatile fingerprints were assessed by gas chromatography flame ionisation (GC-FID) and rapid proton transfer reaction mass spectrometry (PTR-MS) respectively. Chemometric analysis of fatty acid profiles and volatile fingerprints allowed for promising classifications of cereals used in DDGS material by geographical and botanical origin and enabled visual representation of the data. This objective analytical approach could be adapted for routine verification of cereal grains used in the production of DDGS material.
