Clones (1534) in the second clonal stage (Stage 2) of the Canal Point Cultivar Development Program (CPCDP), three reference cultivars, CP78-1628, CP96-1252, and CP00-1101, and three disease-spreader cultivars, CP88-1762, CPCL02-6848, and CP01-2390, were screened to determine SCYLV infection using tissue-blot immunoassay. One hundred seventy-three clones (11%) were infected with the SCYLV, 29 had 100% SCYLV infection, 19 had 80%, 30 had 60%, 38 had 40%, 57 had 20% of SCYLV infection, and 1361 clones had no SCYLV (0%) infection. The 1534 test clones were derived from 400 crosses that utilized 127 female and 86 male parents in various combinations; 70% of these crosses, 46% of the males, and 54% of the females were related to SCYLV-free clones. The reference and disease-spreader cultivar CPCL02-6848 had 48% infection, followed by CP88-1762 with 38% infection, CP96-1252 with 13% infection, CP01-2390 with 6% infection, CP00-1101 with 5% infection, and CP78-1628 with 3%. The results show that SCYLV can infect many susceptible clones within 3 years of exposure from seed germination to Stage 2. However, the effect of SCYLV infection on yield was not significant in this study. Therefore, the yield losses from SCYLV should be limited by planting virus-free seed cane and good agronomic practices in Florida.","PeriodicalId":54362,"journal":{"name":"Sugar Industry-Zuckerindustrie","volume":"4 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89703721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper describes the extraction process as well as its gel forming capability, as one of its most promising functionalities. The excellent gelation properties of this protein make it a highly attractive ingredient in meat alternatives and as an egg-white replacer in many other applications.

A conventional Graver HRT (high retention time) clarifier with a retention time of 150 min at the Tanuku sugar plant was replaced by an SRI-NG (short retention time) SRT clarifier with a residence time of 45 min. A Louisiana Low Turbulence (LLT) SRT clarifier with a residence time of 37 min was then installed on a pilot scale at the Taduvai sugar plant and successfully ran parallel to an existing Graver clarifier. In the off crop, the Graver clarifier was modified to an LLT clarifier. Lamella plate clarifiers are successfully used for many applications, and The Andhra Sugars Ltd. tried lamella clarifiers for juice and syrup clarification during the 2019/20 season. A lamella clarifier with a juice retention time of 7 min was built and used at the Taduvai sugar plant. Based on the encouraging results of the lamella juice clarifier, a lamella syrup clarifier with a syrup retention time of 9 min was installed and operated. The performance of the lamella juice and syrup clarifiers over three consecutive seasons is described. Product quality from the lamella clarifiers was as good as or better than that obtained from conventional clarifiers. The clarifiers operated with significantly lower residence times, with beneficial implications for sugar losses and heat losses. The lamella clarifiers have considerably higher surface loadings than other clarifiers, and their compact size results in much reduced capital costs.","PeriodicalId":54362,"journal":{"name":"Sugar Industry-Zuckerindustrie","volume":"3 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83385231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper reviews non-thermal methods for concentrating juices, mainly focusing on the developments of forward osmosis (FO) membranes for juice processing, detailing the benefits and limitations of this technology. A laboratory FO membrane was used in this preliminary study to concentrate pure sucrose solutions and clarified juice from ~10 to 45% rds using a calcium chloride draw solution. A small amount of reverse salt flux was observed. \u0000The non-sucrose substances in factory juices had little impact on flux performance, with the flux reducing inversely with the volumetric concentration factor. By concentrating to a limit of 45% rds, concentration polarisation factors that can have a detrimental impact on the flux were not realised.

They are characterised by a neutral sweet taste and do not lead to foam or floc formation in applications. Invert sugar syrups are microbiologically more stable than sucrose solutions due to their reduced water activity and the increased osmotic pressure. They are water-clear, odourless and allow easy and safe processing. These are used, for example, in the beverage, confectionery, tobacco and animal feed industries. In Germany alone, more than 10,000 t of invert sugar syrup are used annually for winter feeding of honeybees.\u0000The production takes place in batch or continuously running processes on the scale of the tonnes using homogeneous, heterogeneous acid or even enzymatic catalysis, whereby the molecular incorporation of water increases the amount of sugar, i.e., a mass increase of about 5% takes place. Many invert sugar syrup products can be produced, depending on the degree of inversion. One very important invert sugar syrup product in Germany in terms of quantity has a dry substance of 72.7% and an inversion degree of 66%.","PeriodicalId":54362,"journal":{"name":"Sugar Industry-Zuckerindustrie","volume":"49 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88515821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vanweelden","doi":"10.36961/si29709","DOIUrl":"https://doi.org/10.36961/si29709","url":null,"abstract":"Wireworms (Coleoptera: Elateridae) are the main soil insect pests of sugarcane (Saccharum spp. hybrids) in Florida. Melanotus communis (Gyllenhal) is the most abundant wireworm in Florida sugarcane fields, reducing stalk populations by feeding on buds of sugarcane seed pieces and on young sugarcane plants. At-planting use of the organophosphate insecticide phorate is the main wireworm management tactic in Florida; however, phorate is a hazardous and relatively expensive insecticide. Thiamethoxam is a neonicotinoid insecticide that has potential to become registered for use on sugarcane in the United States. Previous studies suggested that thiamethoxam decreases wireworm injury to sugarcane seed pieces but does not increase wireworm mortality. The present study conducted between 2018 and 2022 aimed to comprehensively evaluate thiamethoxam for wireworm control under laboratory, outdoor, and field conditions. In two laboratory bioassays, M. communis mortality associated with thiamethoxam (3–20%) was not different than mortality for the non-treated check (0–7%), whereas mortality associated with phorate attained 93–100%. In three large container experiments conducted outdoors with controlled M. communis infestations, thiamethoxam and phorate generally protected young sugarcane plant populations at comparable levels. Insecticide efficacy was mainly associated with the protection of seed-piece buds. However, the number of recovered live wireworms was 2.7–8.0 times greater in thiamethoxam treatments than in phorate treatments. In three field experiments, young sugarcane plant populations in thiamethoxam- and phorate-treated plots were not different than those in non-treated plots. However, the at-planting application of thiamethoxam decreased the number of sugarcane thrips, Fulmekiola serrata (Kobus), by 67–89% in two experiments with thrips infestations 12 weeks after planting. Although the evaluation of insecticide efficacy under natural wireworm infestations was inconclusive, this study confirmed that thiamethoxam should be considered as an alternative to phorate if registered. However, the long-term effects of low wireworm mortality associated with thiamethoxam use should be studied.","PeriodicalId":54362,"journal":{"name":"Sugar Industry-Zuckerindustrie","volume":"28 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83675077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These bioactive molecules can be used in the green synthesis of metal nanoparticles. Metal nanoparticles have gathered attention because of their novel physico-chemical properties and potential biological applications (e.g., biocides, fungicides, pesticides, targeted drug and gene delivery, biosensing, medical implants, and plant biostimulants). Gold, silver, iron, and copper nanoparticles are of particular interest as they can be easy to operate and are cost effective, and biocompatible, and their biological activities can be enhanced by surface modifications. In this study, the reducing potential of the phenolic compounds in molasses was investigated for the synthesis of silver nanoparticles without the external addition of reducing agents. The reddish color formation and peak appearance at 420 nm were indications of the successful synthesis of the silver nanoparticles. The synthesized nanoparticles and reducing biomolecules were further characterized by microscopy (SEM, TEM, EDS) and spectroscopy (FTIR) techniques indicating nanoparticles of spherical shape and with particle sizes ranging from 15 nm–45 nm. Their antimicrobial activity was evaluated against several Gram-positive and Gram-negative bacteria. The synthesized nanoparticles showed a biocidal effect, further confirmed by microscopy techniques. It appears that the nanoparticles are interacting with the cell surface of bacteria, penetrating the cell and also causing the disruption of intracellular organelles.","PeriodicalId":54362,"journal":{"name":"Sugar Industry-Zuckerindustrie","volume":"24 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74149875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
