When grown after cotton (loam 2007) or soybean (loam 2008), the N fertilization did not improve the juice yield (P ≥ 0.29). A significant interaction was also found between the effect of the year and N on the juice yield (P < 0.0001). Technical challenges of using sweet sorghum for biofuels are a short harvest period for highest sugar content and fast sugar degradation during storage. There are also some ammonia acids and minerals in the juice which allows the sweet sorghum juice to be used for other purposes. 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. 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. sugarcane molasses were used for ethanol production in this work. Sweet sorghum is an ideal feedstock for fuel ethanol production in the Southeast and Midwest. Nonetheless, the main component of sweet sorghum juice indicated that it is a desirable and cheap carbon resource for the fermentative production of LA. Sorghum syrup is a 100 percent natural sweetener sometimes called “sorghum molasses,” as its flavor and uses are similar to those of molasses … The bagasse can be used to feed livestock or pelletized to burn . It is actually a type of grass not unlike corn. The term “sorghum molasses” is a collo-quial expression incorrectly applied to sorghum syrup. To optimize ethanol yield, a juice extraction rate of at least 50% from the stalks is needed. Sweet sorghum stalks contain up to 75% juice, varying between 12 and 23% in sugar. Sweet sorghum is made from 100 percent pure, natural juice extracted from sorghum (Sorghum bicolor (L.) Moench) cane. Sweet sorghum juice supplemented with 0.5% ammonium sulphate was used as a substrate for ethanol production by Saccharomyces cerevisiae TISTR 5048. overall quality of your sweet sorghum syrup, pay close attention to the cookoff process.

The juice is cleansed of impurities and concentrated by evaporation in open pans into a clear, amber colored, mild flavored syrup. Sweet sorghum juices usually contain approximately 16–18% fermentable sugar, which can be directly fermented into ethanol by yeast. Making drink with sweet sorghum stem juice has great superiority because sweet sorghum is very productive and makes the resource for drink production very rich, and also because this drink is cheaper. Extraction requires a roller mill or diffuser equipment. Spoilage of juice, manifested by a sour odor, discoloration, and foaming, … Sweet sorghum juice supplemented with 0.5% ammonium sulphate was used as a substrate for ethanol production by Saccharomyces cerevisiae TISTR 5048. 15 The content of fermentable sugars in sweet sorghum juice (SSJ) from the stalk could reach 160.00–180.00 g L −1. Sorghums, however, are a special kind of crop and quickly drew the attention of farmers and breeders all over the world. Optimization of media conditions for the production of ethanol from sweet sorghum juice by immobilized Saccharomyces cerevisiae. Sorghum syrup, made by essentially evaporating the water from extracted juice from sweet sorghum stalks, is nothing new to the United States. The sweet sorghum juice had higher cell viability at high ethanol concentrations and minimum sugar concentration at the end of the fermentation process. According to the experimental results, the possibilities to make drink with the juice were studied. Keywords. The juice needs to be processed immediately as it will spoil in seven days. We needed another ‘sweet’ option here on the farm too (we tap maple trees and have bee hives). Identyfikator umowy o grant: JOUB0016 . Disease can alter sorghum juice, reducing the desirability of syrup and contributing to lodging. 2.1. Sweet sorghum has been used for producing sugar, fermenting, and making forage. Glycerol contents in finished beers from concentrated juices were higher than in beers from normal juices. To combat that you can freeze the juice if not using right away. Sweet sorghum juice and traditional ethanol substrate i.e. 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. Well, all over the South at this time of year, folks make a homegrown sugar substitute you might take kindly to: sweet sorghum molasses. Sweet Sorghum, Juice, Sugar, Panicle, Nitrogen 1. of sweet sorghum juice harvested from different cultivars were investigated with regard to pH, yeast concentration, nitrogen source and dilution rate. “We have been handling sweet sorghum and boiling it down as a sugar for more than 200 years,” Heckemeyer said. Samples from each planting date and harvesting stage were stored openly on the ground for 0, 24, and 48 hours before milling. 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. The syrup retains all of its natural sugars and other nutrients. Sweet sorghum (SS) syrup is a high antioxidant food material produced by concentrating its sugary juice. Data zakończenia 31 … Sweet sorghum is a grass of Old World origin. Sorghum belongs to C4 crop with high photosynthetic efficiency and high productivity. Usually sorghum with over 8 °BX of sugar in the juice is called sweet sorghum. 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. Originating in Africa and Asia, where it is still a dietary staple, sweet sorghum was in wide use across the United States from the mid-19th century until the turn of the 20th, when its popularity declined due to the convenience of granulated sugar. Sweet sorghum juices usually contain approximately 16–18% fermentable sugar, which can be directly fermented into ethanol by yeast. 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. Fermentation Sweet sorghum stalk processing for ethanol production Fermentation is a multidisciplinary process based on Juice extraction the chemistry, biochemistry and microbiology of the raw materials.

There are also some ammonia acids and minerals in the juice which allows the sweet sorghum juice to be used for other purposes. The name "sweet sorghum" is used to identify varieties of sorghum, Sorghum bicolor, that are sweet and juicy. Components of sweet sorghum stem juice. In general, loam and sandy loam soils are best for the growth of sweet sorghum for syrup production. The juice yield ranged from 15.2 to 71.1 m 3 ha −1. As demand for and production of fuel ethanol increase to unprecedented levels, feedstocks for ethanol production will become more diverse. Possible ethanol yield can be 600-650 gal/a if all the fermentable sugars in sweet sorghum are converted to ethanol (Wu et al., 2008). 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. 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 juice is known to contain different amount of sugars depending on the type of cultivar (Prasad et al. The reducing sugars and free fructose in stalk juice ranged between 29.72–33.25 and … Enhanced ethanol production from sugarcane juice by galactose adaptation of a newly isolated thermotolerant strain of Pichia kudriavzevii. Materials and Methods . Within the biodiversity found in this crop, there are sorghums that accumulate sugars in the stem, the so-called sweet sorghums. It is difficult to measure the juice Sugar content in the process of production. The sugar is composed mainly of saccharose (70-80 %), fructose and glucose, similar to sugar beet. Sweet sorghum is a grass of Old World origin. … By the 1950s, about 90% of the acreage of sweet sorghums in the United States was grown for forage. 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. 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. The dominant bacterium was Leuconostoc mesenteroides, followed by gram-negative rods. 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.
