sweet sorghum juice


2. It is actually a type of grass not unlike corn. 2 Introduction Bioethanol, a form of renewable energy can be produced from agricultural feedstocks such as sugar cane, sorghum, potato, manioc, and maize. Nonetheless, the main component of sweet sorghum juice indicated that it is a desirable and cheap carbon resource for the fermentative production of LA. Sweet sorghum (SS) syrup is a high antioxidant food material produced by concentrating its sugary juice. Materials and Methods . This study showed that as much as 20% of the fermentable sugars can be lost in 3 days at room temperature because of activities of contaminating bacteria, which lead to significant increases in bacterial count and decreases in pH values. Sweet Sorghum, Juice, Sugar, Panicle, Nitrogen 1. The results indicated that the productivity of ABE fermentation process was improved by gas stripping integration. sugars in sweet sorghum juice are beneficial to the rate of alcohol production. The pH and the density of the juice were not affected by the soil or N. Sweet sorghum [Sorghum bicolor (L.) Moench] is a sugar producing multipurpose crop which is used for simultaneous production of grain (from earhead), sugary juice (from stem) and fodder (leaves and bagasse) for livestock. The juice is cleansed of impurities and concentrated by evaporation in open pans into a clear, amber colored, mild flavored syrup. Sweet sorghum juice supplemented with 0.5% ammonium sulphate was used as a substrate for ethanol production by Saccharomyces cerevisiae TISTR 5048. 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. Sweet sorghum juice extraction, sterilisation and concentration. The juice is cleansed of impurities and concentrated by evaporation in open pans into a clear, amber colored, mild flavored syrup. Juice freshly expressed from Sorghum bicolor for making sweet sorghum syrup contained 10 8 microorganisms per ml. Second, hydroxyl substituents on a given phenolic structure give rise to multiple peaks at different potentials, as observed for quercetin in Fig 1a. In India sweet sorghum syrup is presently being promoted as a health food. The plants were harvested at grain maturity, and juice extracted from the millable stalk was analysed for sucrose contact (Pol percentage), brix and purity. The sweet sorghum juice had higher cell viability at high ethanol concentrations and minimum sugar concentration at the end of the fermentation process. Sweet sorghum juice, obtained from low water consuming, drought resistant, short duration and seed-propagated sweet sorghum crop, was explored as a source to obtain syrup which can be used as sugar alternative for meeting certain requirements of the beverage industry. Sucrose was found to be higher in RSSV 9 (152.20 g/l) as compared to CSH 22SS (106.56 g/l). The ethanol concentration and yield were 8.9% w/v and 0.45 g/g for sweet sorghum in 80 h and 6.5% w/v and 0.37 g/g for sugarcane molasses in 60 h, respectively. and Rutto, L.K. Sorghum syrup, made by essentially evaporating the water from extracted juice from sweet sorghum stalks, is nothing new to the United States. We use cookies to help provide and enhance our service and tailor content and ads. Sweet sorghum (Sorghum bicolor L. Moench) has been considered as an attractive raw material in biorefinery process, and it offers great advantages: greater biomass yield per hectare, high photosynthetic efficiency and wide adaptability to harsh environmental conditions. To combat that you can freeze the juice if not using right away. A field experiment involving 10 sweet sorghum cultivars was undertaken to study the effect of panicle removal at anthesis on juice quality characteristics and sugar yield in sweet sorghum; control plants were left intact. It is one of the many types of cultivated sorghum and is characterized by high sugar content in juice of stem. By continuing you agree to the use of cookies. Sweet sorghum stalks contain up to 75% juice, varying between 12 and 23% in sugar. 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. It is difficult to measure the juice Sugar content in the process of production. As demand for and production of fuel ethanol increase to unprecedented levels, feedstocks for ethanol production will become more diverse. Tìm kiếm fermentation of sweet sorghum juice , fermentation of sweet sorghum juice tại 123doc - Thư viện trực tuyến hàng đầu Việt Nam Thick, juicy stalks make for mighty fine sorghum syrup once squeezed and boiled down over a wood fire. 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. When working with any food product that is to be sold to the public, make sure you follow all state and county requirements. There are also some ammonia acids and minerals in the juice which allows the sweet sorghum juice to be used for other purposes. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. “It was a standard sugar back before World War II. The sugar is composed mainly of saccharose (70-80 %), fructose and glucose, similar to sugar beet. Sweet sorghum is any of the many varieties of the sorghum grass whose stalks have a high sugar content. 2 Experimental 2.1 Materials and chemicals Four different sweet sorghum cultivars, USA 1, USA 2, Honey green and Sugar Graze, were harvested at 3 and 6 months from the Agricol Research Company in Potchefstroom. Raw or unrefined sorghum juice would likely be as hard on a bee's digestive system as unrefined sugar cane juice is. Sweet sorghum is genuinely fit for growing in dryland conditions, as it only requires one-seventh of the irrigation water used by sugarcane. As the crop matures, changes in the composition of the juice and soundness of the stalks influence the syrup quantity and quality. Some features of the site may not work correctly. Arkusz informacyjny. Finally, on combining the cheap nitrogen source and the clarification strategy, 114.6 g L −1 l ‐lactic acid with a productivity of 2.61 g L −1 h −1 was produced by A69 strain in a 5 L bioreactor. 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. Sorghum syrup -- sometimes called sorghum molasses -- has long been a favorite sweetener in the South, and it was particularly popular during the 1800s and early 1900s. Among these isolates, the newly isolated thermotolerant yeast strain, which was designated as Saccharomyces cerevisiae DBKKU Y-53, exhibited great potential for ethanol production from sweet sorghum juice (SSJ) at high temperatures. The term “sorghum molasses” is a collo-quial expression incorrectly applied to sorghum syrup. Soil and N rate significantly impacted the juice yield (P < 0.0001). Well, all over the South at this time of year, folks make a homegrown sugar substitute you might take kindly to: sweet sorghum molasses. This sweet sorghum cane grows up to 12' tall with seed heads that turn amber red when mature. Usually sorghum with over 8 °BX of sugar in the juice is called sweet sorghum. Technical challenges of using sweet sorghum for biofuels are a short harvest period for highest sugar content and fast sugar degradation during storage. Stalk juice from sweet sorghum grown in Southern Illinois, USA, was examined for lipid production through microalgal fermentation. A jar of sweet sorghum syrup. Sorghum syrup and hot biscuits are a traditional breakfast in the Southern United States. Sorghum syrup is also used on pancakes, cornmeal mush, grits and other hot cereals. Juice or syrup is converted into ethanol by Juice is extracted by series of mills (Almodares et al., the yeast Saccharomyces cerevisiae. Significant amount of fermentable sugars remained in the finished beers of these concentrated juices. Semantic Scholar is a free, AI-powered research tool for scientific literature, based at the Allen Institute for AI. The name "sweet sorghum" is used to identify varieties of sorghum, Sorghum bicolor, that are sweet and juicy. 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. The syrup retains all of its natural sugars and other nutrients. The reducing sugars and free fructose in stalk juice ranged between 29.72–33.25 and … A significant interaction was also found between the effect of the year and N on the juice yield (P < 0.0001). Sweet sorghum is known across the southeastern portion of the United States as a sweet and nutritious substitute for sugar products. Thrives in the heat. There are also some ammonia acids and minerals in the juice which allows the sweet sorghum juice to be used for other purposes. We needed another ‘sweet’ option here on the farm too (we tap maple trees and have bee hives). In the photo: Sorghum juice. Sorghum was grown primarily for syrup until the settlement of the semiarid West created a demand for drought-resistant forage crops. In general, loam and sandy loam soils are best for the growth of sweet sorghum for syrup production. a high percentage of extractable juice, (4) contain juice with a high total soluble solids (Brix) content, mostly sugars, (5) ... sweet sorghum, but a soil that has good physical character-istics and good fertility produces the best yield. When grown after cotton (loam 2007) or soybean (loam 2008), the N fertilization did not improve the juice yield (P ≥ 0.29). We’ve always called it ‘cane’ – sorghum is known by many names; sweet sorghum, sorghum cane and all are correct. Ten gallons of sorghum juice will make approximately 1 gallon of syrup. It can be used as a cooking ingredient with a similar sweetening effect as molasses, though blackstrap molasses still has a higher nutritional value than sorghum syrup in most regards. According to the experimental results, the possibilities to make drink with the juice were studied. It was then proved that the efficiency of l ‐lactic acid production was significantly boosted using sweet sorghum juice purified via clarification treatment. Sugar is con- 2008e). By the 1950s, about 90% of the acreage of sweet sorghums in the United States was grown for forage. https://doi.org/10.1016/j.indcrop.2009.10.006. Data rozpoczęcia 1 Lutego 1990. Sorghum-makers press sweet, green juice from the sorghum canes and cook the juice down into a finished syrup. At the end of the fermentation process, the sweet sorghum juice yielded more ethanol with higher ethanol concentration compared to … The dominant bacterium was Leuconostoc mesenteroides, followed by gram-negative rods.Lactobacilli, yeasts, and nonfecal coliform bacteria each comprised about 1% of the microbial population. Sweet sorghum juices usually contain approximately 16–18% fermentable sugar, which can be directly fermented into ethanol by yeast. Sweet sorghum originally had only three utilizations: (1) grain production, (2) sugars and (3) forage. 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). To optimize ethanol yield, a juice extraction rate of at least 50% from the stalks is needed. Keywords. Sorghum juice-derived ethanol is cheaper to produce than corn ethanol because it doesn't require the cooking and enzymes that corn requires for conversion of starch to sugar to fuel grade alcohol. The dominant bacterium was Leuconostoc mesenteroides, followed by gram-negative rods. Fermentation efficiencies of fresh juice, autoclaved juice, and concentrated juice with 20% sugar were higher than 93% in the laboratory shake flask batch process. of sorghum, Sorghum bicolor (L.) Moench, that are sweet and juicy. 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. The high levels of different sugars in sweet sorghum juice are beneficial to the rate of alcohol production. 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. Therefore the drink has stronger competitiveness for its low price. ‘Rio’ sweet sorghum [Sorghum bicolorz (L.) Moench.] Disease can alter sorghum juice, reducing the desirability of syrup and contributing to lodging. A total 24 g/L of ABE solvents was obtained from 59.6 g/L of initial sugar after 80 h of fermentation with gas stripping. First, sweet sorghum juice is expected to contain a complex mixture of polyphenols, rather than a single chemical structure such as quercetin. , 2007). **WARNING** DO NOT FEED RAW SORGHUM LEAVES OR ANY PART OF THE SORGHUM GREENS TO PETS OR LIVESTOCK without researching first. Journal of Biomimetics, Biomaterials and Biomedical Engineering Materials Science. Sweet sorghum juice is a liquid sugar feedstock that can be produced in non-tropical climates. Sweet sorghum also possesses high photosynthetic efficiency and high biomass yield, so it has become more attractive in agricultural production. Glycerol contents in finished beers from concentrated juices were higher than in beers from normal juices. The juice yield ranged from 15.2 to 71.1 m 3 ha −1. Better and faster floc precipitation is further aided by HMW polyanionic acrylamide flocculants which agglomerate particles and add weight. Also, sugarcane is not a salt tolerant plant. 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 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). Components of sweet sorghum stem juice. Sucrose was found to be higher in RSSV 9 (152.20 g/l) as compared to CSH 22SS (106.56 g/l). conditions of sweet sorghum juice during fermentation. Sorghum bicolor, or better known as sweet sorghum, has three different components which can be used for ethanol production: grain, bagasse, and the juice [9,10].The juice extracted from the plant stalks contains plenty of sugars, such as sucrose, glucose, and fructose, which can be directly converted via biological fermentation process into ethanol [11,12].
