The plants were harvested at grain maturity, and juice extracted from the millable stalk was analysed for sucrose contact (Pol percentage), brix and purity. By the 1950s, about 90% of the acreage of sweet sorghums in the United States was grown for forage. Sweet Sorghum, Juice, Sugar, Panicle, Nitrogen 1. We needed another ‘sweet’ option here on the farm too (we tap maple trees and have bee hives). Semantic Scholar is a free, AI-powered research tool for scientific literature, based at the Allen Institute for AI. The high levels of different sugars in sweet sorghum juice are beneficial to the rate of alcohol production. Sweet sorghum juices usually contain approximately 16–18% fermentable sugar, which can be directly fermented into ethanol by yeast. Sorghum belongs to C4 crop with high photosynthetic efficiency and high productivity. , 2007). In general, loam and sandy loam soils are best for the growth of sweet sorghum for syrup production. Sorghum syrup, made by essentially evaporating the water from extracted juice from sweet sorghum stalks, is nothing new to the United States. https://doi.org/10.1016/j.indcrop.2009.10.006. It is difficult to measure the juice Sugar content in the process of production. Sweet sorghum is an ideal feedstock for fuel ethanol production in the Southeast and Midwest. We’ve always called it ‘cane’ – sorghum is known by many names; sweet sorghum, sorghum cane and all are correct. Sugars content in sweet sorghum stalk juice mostly were sucrose and invert sugars which invert sugars are included glucose, fructose, maltose and xylose (Almodares et al., 2008c). Spoilage of juice, manifested by a sour odor, discoloration, and foaming, … Sweet sorghum juice is a liquid sugar feedstock that can be produced in non-tropical climates. Sweet sorghum juice yield varied between 15.2 and 71.1 m 3 ha −1 depending on the year, the soil type, and the N rate (P < 0.0001) (Table 5). Sweet sorghum juice supplemented with 0.5% ammonium sulphate was used as a substrate for ethanol production by Saccharomyces cerevisiae TISTR 5048. The reducing sugars and free fructose in stalk juice ranged between 29.72–33.25 and 11.38–14.40 g/l, respectively, among two genotypes. Stalk juice from sweet sorghum grown in Southern Illinois, USA, was examined for lipid production through microalgal fermentation. In the photo: Sorghum juice. After extraction of sugars containing juice from sweet sorghum stalk, the bagasse is available in large quantities that can be used as fuel in boilers in the sugar mills for the cogeneration process. Defect and Diffusion Forum Enhanced ethanol production from sugarcane juice by galactose adaptation of a newly isolated thermotolerant strain of Pichia kudriavzevii. Sweet sorghum (SS) syrup is a high antioxidant food material produced by concentrating its sugary juice. The sweet sorghum bagasse (SSB) after squeezing the fermentable juice was used as the immobilized carrier. The total sugar content of the juices extracted from the different cultivars used in this study at different harvesting times is presented in Table 1. Samples from each planting date and harvesting stage were stored openly on the ground for 0, 24, and 48 hours before milling. These results help to identify the most important factors affecting the quality of sweet sorghum juice under different processing and storage conditions, enabling development of effective strategies to process the juice, preserve fermentable sugars, and retain the processing properties of the juice during processing, transportation, and storage. conditions of sweet sorghum juice during fermentation. Sweet sorghum is known across the southeastern portion of the United States as a sweet and nutritious substitute for sugar products. The bagasse can be used to feed livestock or pelletized to burn . There are also some ammonia acids and minerals in the juice which allows the sweet sorghum juice to be used for other purposes. CSH 22SS contained higher amounts of reducing sugars and free fructose than RSSV…, Increasing Bioethanol Yield from Fermentation of Sweet Sorghum ( Sorghum bicolor L. Moench) Sap by Mixed Culture Composed of Two Yeast Strains, Xylanase Production by Isolated Fungal Strain, Aspergillusfumigatus RSP-8 (MTCC 12039): Impact of Agro-industrial Material as Substrate, Sweet sorghum-a promising alternative feedstock for biofuel production, AVALIAÇÃO DA FERMENTAÇÃO DE CALDO DE SORGO SACARINO EMPREGANDO LEVEDURAS COMERCIAIS, Chapter 4A – Sugar- and Starch-Based Biorefineries, ETHANOL RECOVERY AND BIOCHEMICAL STUDIES OF SOME ELITE SWEET SORGHUM CULTIVARS, Features of sweet sorghum juice and their performance in ethanol fermentation. “We have been handling sweet sorghum and boiling it down as a sugar for more than 200 years,” Heckemeyer said. Sweet sorghum is a grass of Old World origin. Another option is to pasteurize (boil) and can. Second, hydroxyl substituents on a given phenolic structure give rise to multiple peaks at different potentials, as observed for quercetin in Fig 1a. Sorghum syrup and hot biscuits are a traditional breakfast in the Southern United States. Sucrose was found to be higher in RSSV 9 (152.20 g/l) as compared to CSH 22SS (106.56 g/l). Calcium, from the juice and MOL, and phosphorous that occurs naturally in the sweet sorghum juice are necessary for the formation of calcium-phosphate bridges that aid in the flocculation process. Drought tolerant. Sweet sorghum juice supplemented with 0.5% ammonium sulphate was used as a substrate for ethanol production by Saccharomyces cerevisiae TISTR 5048. The juice yield ranged from 15.2 to 71.1 m 3 ha −1. By continuing you agree to the use of cookies. Technical challenges of using sweet sorghum for biofuels are a short harvest period for highest sugar content and fast sugar degradation during storage. Sweet sorghum is genuinely fit for growing in dryland conditions, as it only requires one-seventh of the irrigation water used by sugarcane. It is actually a type of grass not unlike corn. Sorghum syrup is a 100 percent natural sweetener sometimes called “sorghum molasses,” as its flavor and uses are similar to those of molasses … Sweet Sorghum - A Potential Alternate Raw Material for Bio-ethanol and Bio- energy, An assessment of sweet sorghum cultivars for ethanol production, View 2 excerpts, references background and results, By clicking accept or continuing to use the site, you agree to the terms outlined in our. Sweet sorghum [Sorghum bicolor (L.) Moench] is the best multipurpose crop for simultaneous production of (i) grain from its earhead as food, (ii) sugary juice from its stalk for making syrup, jaggery or ethanol and (iii) bagasse and green foliage as an excellent sugarcane molasses were used for ethanol production in this work. It is one of the many types of cultivated sorghum and is characterized by high sugar content in juice of stem. Sweet sorghum also possesses high photosynthetic efficiency and high biomass yield, so it has become more attractive in agricultural production. As demand for and production of fuel ethanol increase to unprecedented levels, feedstocks for ethanol production will become more diverse. Raw or unrefined sorghum juice would likely be as hard on a bee's digestive system as unrefined sugar cane juice is. Sweet sorghum juice is known to contain different amount of sugars depending on the type of cultivar (Prasad et al. The sweet sorghum juice had higher cell viability at high ethanol concentrations and minimum sugar concentration at the end of the fermentation process. Copyright © 2009 Elsevier B.V.

ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. … Sweet sorghum originally had only three utilizations: (1) grain production, (2) sugars and (3) forage. Interest in sorghum syrup is renewed whenever a shortage of sugar results in higher sugar prices. The objective of this study was to assess the agronomic performance and juice yield of five sweet sorghum cultivars (Keller, Della, Dale, M81E and Sugar Drip) as potential sources of biomass and grain for ethanol production. Extraction requires a roller mill or diffuser equipment. Significant amount of fermentable sugars remained in the finished beers of these concentrated juices. The juice is cleansed of impurities and concentrated by evaporation in open pans into a clear, amber colored, mild flavored syrup. Around the end of World War I, refined sugar products became more readily available and less expensive, thus causing a decline in the use of sorghum as a sweetener. Sweet sorghum has been used for producing sugar, fermenting, and making forage. Sweet sorghum is a grass of Old World origin. Data rozpoczęcia 1 Lutego 1990. The name "sweet sorghum" is used to identify varieties of sorghum, Sorghum bicolor, that are sweet and juicy. At the end of the fermentation process, the sweet sorghum juice yielded more ethanol with higher ethanol concentration compared to … Also, sugarcane is not a salt tolerant plant. The chemical composition of stalk juice of genotypes RSSV 9 and CSH 22SS of sweet sorghum and production of ethanol by fermentation in shake flasks and laboratory fermenter were determined. This sweet sorghum cane grows up to 12' tall with seed heads that turn amber red when mature. It was then proved that the efficiency of l ‐lactic acid production was significantly boosted using sweet sorghum juice purified via clarification treatment. The main component of the sugar in sweet sorghum stem is saccharose. In India sweet sorghum syrup is presently being promoted as a health food. Arkusz informacyjny. Sucrose was found to be higher in RSSV 9 (152.20 g/l) as compared to CSH 22SS (106.56 g/l). Harvesting the Crop The last step in producing the crop and the first step in obtaining high quality sorghum syrup is harvesting the crop at the proper stage of maturity. Abstract. Utilization of sweet sorghum juice as a feedstock for the production of lysine was investigated utilizing the auxotrophic mutant Corynebacterium glutamicum ATCC 21513 in stirred tank bioreactors. In batch fermentation, kinetic parameters for ethanol production depended on initial cell and sugar concentrations. was planted April 1, May 1, and June 1 and was harvested in the flower, milk, dough, and ripe stages of maturity.
