Background and Objectives Cereal‐based bioethanol stillage, the main by‐product of industrial bioethanol production, is a potential substrate for fructans. However, the quantification of fructans in such complex sample matrices is still a challenge for the corresponding analytics to be overcome to allow for the identification and utilization of such unused fructan sources. Especially a possible utilization or rather the corresponding process development requires appropriate analytics first. Thus, this paper aims to develop and apply a method for fructan quantification in bioethanol stillage using common a high‐performance liquid chromatography–refractive index detector. Findings A new approach for fructan quantification is presented allowing for simple fructan determination in bioethanol stillage for comparably high sample throughput. The developed analytical method performs fructan quantification by means of fructose‐ and glucose‐equivalent determination after targeted acidic hydrolysis adapted to the respective sample matrix. On the basis of this method, up to 2.5% of fructans were found in the dry matter of cereal‐based bioethanol stillage. Conclusion Cereal‐based bioethanol stillage is assessed to be a potential source of fructans. The presented analytical method can be the basis for respective process development and, thus, may contribute to a higher‐value utilization of stillage. Significance and Novelty According to current knowledge, no determination of fructans in stillage or corresponding analytical methods have been published so far.

Bioethanol stillage, the main by-product of industrial bioethanol production, is a potential substrate for fructans. However, the determination and quantification of fructans in such complex sample matrices is still a challenge for the corresponding analytics to be overcome in order to allow for the identification and utilisation of such unused fructan sources. Especially a possible utilisation or rather the corresponding process development requires appropriate analytics first. Thus, this paper aims to illuminate the basics of fructan quantification in stillage and the corresponding challenges particularly arising with widely used HPLC-RID systems. On this basis, a new approach for fructan quantification is presented based on such HPLC-RID systems allowing for a reliable and especially simple fructan determination in bioethanol stillage for comparably high sample throughput. The developed method performs fructan quantification by determination of fructose and glucose equivalents after a targeted acidic hydrolysis adapted to the respective sample matrix. By means of two different stationary phases, the problem of limited resolution in case of HPLC-RID is overcome and thus measurement errors are reduced. The approach towards the adapted analytical method can be transferred easily to comparable complex sample matrices.

“…Several nutritional strategies have been identified to minimize the stress associated with abrupt weaning, such as optimizing energy levels of the diet and using feed additives (probiotics, prebiotics, SCFA, phytogenic compounds and nucleotides) post-weaning (7,9). Several studies (10)(11)(12)(13)(14) have reported the beneficial effects of several prebiotics such as inulin, fructans, fructo-/galactooligosaccharides, and resistant starch on weaning animals, such as boosting intestinal immunity, regulating microbial fermentation, and modulating intestinal tight junction in weaned piglets. In recent years, there has been a growing body of literature that highlights the importance of prebiotics for easing the impact of weaning stress in young animals.…”

IntroductionAbrupt weaning is a major stressful event, contributing to intestinal abnormalities and immune system dysfunction in weaned kids. Inulin is a prebiotic fiber with many positive functions, including promoting intestinal fermentation and enhancing host immunity in monogastric animals. However, the effects of a high-inulin, energy-rich diet on ruminal fermentation characteristics, methane emission, growth performance, and immune systems of weaned kids have not been investigated.MethodsA fully automated in vitro fermentation system was used to investigate ruminal fermentation characteristics and methane emission of a mixed substrate of inulin and fat powder (1.31: 1) in comparison with maize grain-based starter concentrate. During a 1-week adaptation and 4-week trial phase, 18 weaned kids (8.97 ± 0.19 kg) were randomly assigned to two groups, one with a conventional diet (83% maize grain; CON) and the other with a low-carbon, high-inulin diet (41.5% maize grain, 14.4% fat powder, 18.9% inulin; INU).ResultsIn the in vitro rumen fermentation experiment, the total gas production was not different (p > 0.05); however, a lower (p < 0.05) methane production was observed for INU as compared to CON. The average daily gain and the ratio of feed intake and growth performance of kids fed with INU were higher (p < 0.05) than those fed with CON. Serum concentrations of alanine transaminase (ALT) and lactate dehydrogenase (LDH) were lower (p < 0.05), whereas the concentration of high-density lipoprotein (HDL) and cholesterol (CHOL) were higher (p < 0.05) in kids fed with the INU diet as compared CON. Dietary inulin significantly increased (p < 0.05) the secretion of immunoglobulins (IgA, IgG, and IgM) and inflammatory cytokines (IFN-γ and IL-10) in ileum tissue. Although no differences (p > 0.05) were observed in mRNA expression of tight junction markers, the INU diet tended to increase (p = 0.09) gene expression of ribosomal protein S6 kinase beta-1 (P70S6K) in the mammalian target of rapamycin (mTOR) pathway of longissimus dorsi muscle.ConclusionOur findings highlighted that a low-carbon high-inulin energy-rich diet could be used as a promising strategy to improve gut immunity and growth performance of weaned kids under abrupt weaning stress and reduce methane production.
