Single cell proteins : A novel value added food product

2016

Single cell proteins are the biomass (dried cells) produced by microorganisms including yeast, bacteria, algae and fungi. This biomass contains proteins, amino acids, vitamins and lipid content. The microorganisms utilize waste materials, agricultural and industrial waste, feed stocks and secrete natural protein concentrates. A variety of substrate s are available for the production of single cell proteins, most common among them is the yeast which produces 250 tons of proteins in 24 h. Single cell proteins can be used as a vital supplement of proteins and regarded as a quantitative approach against malnutrition. Two main reasons for the replacement of single cell proteins by conventional source are its high nucleic acid content and low digestibility. Single cell proteins have a wide field of applications in animal nutrition, in food stuffs and in technological fields. The production process and research and development of single cell proteins are encompassing various fields of scie...

Production of single cell protein from different food waste

IRJET, 2023

Proteins are one of the most important nutrients required for both human as well as animal health. There is a need to find new solutions to suffice the world population's demand for protein consumption which cannot be obtained just by consuming plant-based protein or animal-based protein. Hence, the best alternative would be to switch to Single Cell Protein (SCP) which would also serve to improve the world's food security and scarcity. The food wastes have the potential to be used by microorganisms as substrate during fermentation processes to produce single cell protein. This review focuses on the utilization of several food wastes as a substrate through the process of batch fermentation to produce single cell protein using Saccharomyces cerevisiae as the source of microorganism. Comparative analysis of application of orange peel, banana peel, apple peel, pineapple peel and fish waste as substrate to produce single cell protein has shown that they all can be used together without the need for segregation. The product obtained yielded a good protein content and hence, could be used as a potential protein substitute for animal feed. More sustainable and economical methods of producing single cell protein are being discovered by researchers all over the world. Hence, the application of single cell protein for both human as well as animal feed could be a great alternative solution to protein sources through simultaneous bio-valorization of food waste.

Single Cell Protein for Foods and Feeds: A Review of Trends

The Open Microbiology Journal

Introduction: Predictions on the world’s population in the next few decades suggest that the global demand for animal-derived proteins may not be met if current conventional agriculture approaches are used. One promising solution to this complex crisis lies in the use of single-cell proteins (SCP). SCP refers to the edible biomass of unicellular microorganisms and can be developed as animal feeds or human foods. This paper provides a detailed overview on research towards the production and utilisation of SCPs and trends within the field. Study Design: A bibliometric based study was conducted on 425 SCP research articles collected from the Web of Science database, analysing the most cited papers using VOSviewer software, and contributing authors, affiliations and country of origin. Research publications on SCP started in 1961 and has grown steadily over the years. Discussion: Emerging research topics within SCP production focused on the use of improved fungal strains, the composition...

Review on Production of Single-Cell Protein from Food Wastes

Turkish Journal of Agriculture - Food Science and Technology, 2021

The roles of protein in bodybuilding and the regulation of biological processes are important in sustaining life. A large amount of protein is required by both humans and animals and this cannot be supplied by only conventional sources. This is because of the rapid increase in world population. The present sources of protein will not meet global protein demand in years to come. Scientists explore the production of single-cell protein (SCP), as an alternative source of protein, through the utilization of wastes and low-value materials. SCP can supply high-quality protein containing both essential and non-essential amino acids that can be utilized by humans and animals. Protein from microbial biomass is cheaper than animal proteins because the substrates used in the production are generally cheaper and more readily available. Moreover, the production process does not require arable land and the entire process can be completed within a short time. This article reviewed the process of S...

Single Cell Protein: A Potential Substitute in Human and Animal Nutrition

Sustainability, 2021

Single cell protein (SCP) is the first product of the fermentation process and has proven to be a good protein alternative. Food competition is becoming more intense as the world’s population continues to grow. Soon, SCP may be able to compensate for a protein deficit. Various global businesses are focusing on SCP production, and the scope of its application is expanding as time and knowledge increases. High quantities of SCP can be produced by microorganisms, such as algae, yeast, fungi and bacteria, due to their fast development rate and the significant level of protein in their chemical structure. Beside proteins, SCP contains carbohydrates, nucleic acids, lipids, minerals, vitamins and several important amino acids. SCP has been an effective substitute for more expensive protein sources such as fish and soybean products. In conclusion, SCP can easily replace traditional protein sources in human and animal feed without detrimental effects. Potential substrate candidates and optim...
