Agrifood

With only 1% of land available for food production, Singapore relies on imports for 90% of its food supply. To meet the goal of producing 30% of the nation's nutritional needs locally by 2030, enterprises can adopt innovative agrifood technologies. Technologies that enhance agri-inputs and resource efficiency for highly productive urban farming systems in agriculture and aquaculture, together with innovations in alternative proteins, food side stream valorisation and solutions to enhance food safety can pave the way for sustainable and resilient food systems, contributing to long-term food security for Singapore.

Discover IPI’s curated list of technologies and solutions, as we aim to strengthen Singapore's food security, ensuring resilience in the food supply chain while promoting sustainable and profitable agricultural practices.

Converting Seafood Sidestreams Into Nutritious Foods
Asia accounts for approximately 70% of the world’s seafood consumption, around 69.6 million metric tons. This is more than twice the total amount consumed by the rest of the world.* Commercially, about 30% of the seafood is not consumed, from bones to offals, to skin/shell/scales. These food loss and waste potentially impose environmental and socioeconomic issues.  The technology provider has developed a green chemical process converting seafood sidestreams into food products that are not only high value but also nutritious, addressing Singapore’s demand to increase production of nutrient dense foods. In addition, this method is efficient and cost effective as it requires basic equipment. The technology provider is looking for R&D collaborators and for test-bedding especially with industries who are producing aquaculture food with high nutritional value and interested to utilise their sidestreams more sustainably. * FAO 2018
Cost-effective Okara-based Shrimp Feed Formulation
Feed cost generally accounts for 60% to 70% of the total production costs in an intensive shrimp aquaculture system. Fishmeal, which is often the main ingredient of shrimp feed, is one of the reasons for the high cost. It is also unsustainable to use fishmeal as it is derived from fish, contributing to the depletion of other fish species on a global scale. The technology offer is an alternative protein source in shrimp feed that uses okara, a nutrient-dense side stream from soy milk and bean curd production. Direct application of unprocessed okara into shrimp feed may work, however, due to the presence of anti-nutrients, the absorption of protein and amino acids from the okara may be limited. The technology developer has formulated a shrimp feed with an optimum amount of processing to increase the digestibility and enhance the nutritional properties and at the same time lowering the cost of shrimp feed by up to 50%. Currently, the developer has developed shrimp feed suitable for L. vannamei shrimp species with complete or partial replacement of animal protein which is fish meal. The technology is available for IP licensing and IP acquisition as well as R&D collaboration with industrial partners who are keen to adopt the solution. 
Automated Environmental Control for Indoor Farming
Indoor farming presents a range of different challenges to crop yields compared to outdoor farming activities. Traditional outdoor farmers intuitively know what environmental factors affect the growth of the crop. Indoor farming, on the other hand, requires the farmer to simulate the optimal climate conditions for expected crop yields. The indoor climate can either contribute to the yields or, in unfortunate circumstances, lead to the loss of the crop. However, it is not always easy to create an ideal environment for the crop.  This technology offer is a control system that allows the facility manager to align optimal crop conditions with the equipment settings in their facility, minimising the drift between settings and site-level crop conditions. The control system can also be used to compute the correlation between data across crop production, environment, and business performance. The control system can be customised further by adding other sensors for better accuracy of control.  The technology owner is keen to do R&D collaboration and licensing with innovative industrial automation companies specialising in product development of sensor networks and high-data throughput IoT gateways.   
Temperature Regulated and Modular Rooftop Greenhouse Farming
Singapore is currently only producing 13% of its vegetable consumption. With little farming land available, Singapore relies heavily on imports from other countries. Due to increasing focus on food security, the alternative to solve land scarcity problem is to build greenhouses on concrete rooftop. Although concrete rooftop greenhouse are able to keep pests out, there is a signifcant heating problem which severely inhibits the growth of the vegetables. Therefore, there is a need for a rooftop greenhouse that is able to actively cool itself to avoid such problem. This technology offer is a modular rooftop greenhouse farming system (hydroponics) capable of producing vegetables on concrete roofs to meet the local demand while reducing over-reliance on imports. The design of the greenhouse farming system enables cooling and does not heat up, thus allowing the growth of pest-free vegetables. The system is approximately the size of a typical carpark lot (2.5 x 5 m). The production rate is 30 kg per month (2.5 x 5 m size) and requires minimal human intervention. The technology offer comprises both the farming system and its operation know-how. The modular rooftop greenhouse farming system can be set-up within 3 days or scaled-up when required with guaranteed vegetable growth. The break-even cost of one greenhouse is about 3 years. The technology owner is seeking to out-license their technology.
Optimised Nutrient Formulation for Improving Crop Yield
Different plant species have different nutrient requirements. The current practice of urban farming uses a generic hydroponic nutrient solution that is suitable to most plant types, and a crude sensing system that only measures total ion content in the solution. This approach often results in nutrients deficiency and/or overloading and hence requires consistently monitoring. Overloading of nutrients not only increases the input costs, it also results in greater quantities of contamination in effluent to be disposed after harvest.  A targeted hydroponic nutrient solution reduces the need to periodically adjust the nutrient. The technology provider has studied and formulated different nutrient recipes that had shown improved yield compared to commercial products. This ensures the best growth for each crop type. It also reduces common problem stemming from imbalanced nutrient, e.g. leaf chlorosis due to nutrient deficiency. All these translate to a better yield and a more marketable produce for the farmers. Formulations developed include Mizuna, Kale, Lettuce, Mustard, Kalian, and Caixin. The technology provider is seeking for licensing partners from the agriculture industry.
Rapid Screening of Heavy Metals in Food/Feed Powders
The presence of heavy metals in food or feed powders involves contamination of the food chain and potential harm to public health, as such, rapid detection is a time-critical issue. The uncertainty about food safety caused by the possible presence of heavy metals is of concern to consumers and regulatory authorities and this is typically addressed by increasing the testing frequency of food or feed samples. However, existing testing methods are often time-consuming and require highly skilled laboratory personnel to perform the testing. This technology employs spectroscopic imaging methods and machine learning techiniques to rapidly detect heavy metals in food or feed samples. The machine learning model can perform a multi-class differentiation of the various heavy metals based on spectroscopic measurements. It is also able to predict the concentration of heavy metals present in food or feed powders using spectroscopic measurements. Minimal sample preparation is required for this method, allowing for the rapid screening of food or feed powder samples. The technology owner is interested in collaboration with companies working with food powders, with an interest in heavy metal content within food powders.   
Maximising Cell Cultivation With Low Cost 3D Scaffolding
The current clean meat technologies grow lab meat with conventional 2D cell culture. However, the conventional cell culture technique has an overall low yield of cells, as the cells are restricted to growth on surface areas.  A new 3D scaffolding method has been developed to overcome this problem with the use of microcarrier beads that provide cells with additional surface area to attach onto and proliferate. The microcarrier beads are suspended in the cell culture thus maximizing the 3D volume of the cell culture, leading to an increased yield. A microcarrier type has been identified to yield the highest number of porcine cells. The conditions of the cell culturing process have been optimised to improve the cell viability in a 3D environment Companies interested in cell-cultured meat development could consider using this method to grow cell-cultured meat at a larger scale with a potentially lower cost of production. The technology developer is seeking companies that are keen to scale up lab-grown meat applications. 
Wavelength-selective Solar Photovoltaic System (WSPV) For Urban Rooftop Farming
This technology offer helps to address the problems of global warming, food security crisis and energy crisis. With the increase in human population and rapid urbanisation, the change in weather patterns and increase in food demand has been inevitable. One of the major concerns faced in Singapore, due to global warming, is the urban heat island effect. This occurs when urban areas in cities have a higher air, surface and soil temperature than rural areas. Initiatives for high-rise greenery has been put in place to help solve the problem. However, there has been problems with limited space and high maintenance cost for these greeneries. Rooftop hydroponics farming is a possible solution to offset the running costs of rooftop greeneries or even generate profits for rooftop greeneries as it produces fresh produce, while simultaneously reducing the urban heat island effect. The reduction in urban heat island is due to a combination of green and blue body acting as a thermal buffer and contributing to the building sustainability (due to reducing in cooling costs). This initiative addresses the constraints of limited land, as solar energy generators require large areas for photovoltaic panels to be laid. This technology offer aims to provide an integrated solution to this economic challenge for environmentally sustainable urban planning. This Technology Offer is a luminescent solar concentrator that enables both power generation by photovoltaic modules, as well as efficient urban rooftop farming.
A Distributed Ledger Technology Application to Manage Food Supply Chain
Food tracking and traceability systems can utilize Distributed Ledger Technology (DLT) and Internet-of-Thing (IoT) sensors to streamline the workflow of food supply chain management. Such a traceability system mitigates the complex business processes and speeds up the workflow of working through multiple business owners along the nodes in the value chain. This Technology Offer is a DLT application that can be used to manage the food supply chain. The technology aims to obtain transparency, ease of transactions and speed of delivery, synchronization, tracking and security. As an example, IoT sensors can be attached to livestock to obtain information about them from the source, and is uploaded to the ledger data of the node. When the livestock is shipped to the manufacturer, shipment tracking data can be uploaded. The transport is thus done with trackable ownership, possession and telemetry parameters such as location, temperature, humidity and activity. The manufacturer then processes the livestock, weighs the meat, packs and labels them. The label has a unique cryptographic QR code or NFC tag that links to the data citing the origins of the meat. The packaged meat is then shipped to the distributors, and eventually reaches the buyer. The final buyer can access a complete record of information and trust that the information is accurate and complete.
