Freeze concentration techniques as alternative methods to thermal processing in dairy manufacturing: A review

Journal of Food Science, Journal Year: 2022, Volume and Issue: 87(2), P. 488 - 502

Published: Jan. 20, 2022

Freeze concentration technology is applied to concentrate liquid foods at low temperatures, thus separating pure ice crystals from the final solution. This method an interesting alternative food with high water levels and significant nutritional value such as dairy products, since several bioactive compounds are reduced when exposed elevated temperatures. Considered that, this technique may be a great concentrating maintaining both sensory characteristics of foods. The present review aims introduce freeze procedures eligible choice for conserving products', also addressing its effects on matrix. PRACTICAL APPLICATION: study reports main techniques applications in used industrial laboratory scale, aiming improve quality products obtained.

Valorization of biorefinery residues for sustainable fertilizer production: a comprehensive review

Biomass Conversion and Biorefinery, Journal Year: 2023, Volume and Issue: 13(16), P. 14359 - 14388

Published: July 24, 2023

Abstract The management of biowaste and agricultural solid waste is gaining attention due to rising landfill disposal costs the need for locally available feedstocks. biorefinery concept aims achieve zero through valorizing residues as fertilizers. Despite containing NPK macronutrients, may not promote plant growth limited nutrient availability phytotoxic compounds. production valuable organic, mineral-organic, or mineral fertilizers with confirmed agronomic properties marketable products remains understudied. This comprehensive review broadens our understanding fertilizer in biorefineries, which complements energy (thermal, biogas, biodiesel) chemical compounds (e.g., succinic acid, propanediol, protein concentrates) that are also generated within biorefineries. It among first reviews investigate importance fertilizers, emphasizing methods leading commercial rationale behind this process. findings confirm directly applying unprocessed soil does fully exploit their value by-products. study contributes practical analysis barriers (legal, chemical, biological, technological) opportunities (rising prices reduced global fertilizers) related biorefining

Sustainable Resource Recovery from Dairy Waste: A Case Study of Hydrothermal Co-liquefaction of Acid Whey and Anaerobic Digestate Mixture

Energy & Fuels, Journal Year: 2023, Volume and Issue: 37(4), P. 2897 - 2911

Published: Jan. 27, 2023

Uncontrolled emission of carbon and nutrients due to mismanagement dairy waste leads global warming, eutrophication water bodies, aerosol pollution, acidification ecosystems. We studied hydrothermal liquefaction (HTL) sustainably recover resources by converting the wastes into carbon-dense biocrude oil a nutrient-rich aqueous-phase coproduct. evaluated acid whey as an alternative source catalyst, replacing acetic acid, for HTL anaerobically digested cattle manure (manure digestate). Using well-designed experiments, we investigated effects several factors on product formation fate elements well underlying chemistry. The included reaction temperature (280–360 °C), time (10–50 min), mixing ratio digestate (AW/MD 0–2), amount additional required, that is, specified based final feedstock pH between 3.5 5.5. experimental results suggested following optimal conditions enhanced maximal nutrient yield in coproduct: AW/MD 1.21, mixture 4.5, 354 °C 21 min, respectively. Under such conditions, was 40–50% (equivalent 60–80% energy recovery) via cyclic acetalization, hydroxymethylation, isomerization, Piancatelli rearrangement, oxidation, condensation with heteroatom removal deoxygenation denitrogenation mechanisms. Moreover, these provided adequate solubilize Mg-carbonate Ca-phosphate minerals catalyzed deamination N-heterocyclics other nitrogenous compounds, producing higher recoverable Mg, NH3-N, P, K coproduct, 60–70, 30–40, ∼40, >95%, This study demonstrated potential using coprocessing measurably valorize biomass key component achieving circular bioeconomy industry.

Pathways for the Valorization of Animal and Human Waste to Biofuels, Sustainable Materials, and Value-Added Chemicals

Environments, Journal Year: 2023, Volume and Issue: 10(3), P. 46 - 46

Published: March 6, 2023

Human and animal waste, including waste products originating from human or digestive systems, such as urine, feces, manure, have constituted a nuisance to the environment. Inappropriate disposal poor sanitation of often cause negative impacts on health through contamination terrestrial environment, soil, water bodies. Therefore, it is necessary convert these wastes into useful resources mitigate their adverse environmental effect. The present study provides an overview research progress different thermochemical biological conversion pathways for transformation human- animal-derived valuable resources. physicochemical properties are meticulously discussed, well nutrient recovery strategies. In addition, bibliometric analysis provided identify trends in knowledge gaps. results reveal that USA, China, England dominant countries areas related resource waste. researchers University Illinois, California Davis, Chinese Academy Sciences, Zhejiang front runners areas. Future could be extended development technologies on-site resources, exploring integrated pathways, safe processing methods.

Climate change, characterized by the increased frequency and intensity of extreme weather events, is greatest environmental challenge threatening global food systems. Its impacts are particularly severe for livestock production systems in developing countries. In low-and middle-income countries (LMICs), provides critical livelihoods millions vulnerable people plays a significant role security. However, sector highly susceptible to adverse effects climate change. change LMICs associated with erratic rainfall, rising temperatures, flooding, drought, desertification, higher events. particular, when temperatures exceed thresholds projected Intergovernmental Panel on Change (IPCC), subjected heat stress, which reduces productivity, lowers conception rates, can be life-threatening many species. response, various adaptation strategies have been implemented enhance resilience This review evaluates existing including their effectiveness proposes simplified targeted build Key measures include genetic improvement diversification species, early warning systems, precision farming technologies, climate-smart strategies, institutional policy frameworks capacity-building initiatives. Further, key factors influencing outcomes such as governance, financial investment, community engagement, technological infrastructure were highlighted. While some breeding programs heat-tolerant yielded positive results, challenges limited resources, weak frameworks, resistance hinder widespread adoption. The also recommendations improving enhanced investment data-enabled innovations, integration policies into national development plans, participatory approaches involving local farmers. conclusion, this study roadmap building climate-resilient ensure sustainable improved under changing climate.
