Higher productivity in the potato value chain in Rwanda requires good quality seed potatoes. The article analyzes how innovations were introduced in the framework of a development project resulting in a partnership between a firm and two educational institutions to produce better seed potatoes, using the Triple Helix approach.

In the Triple Helix model government, academia and the private sector work together to develop and introduce innovations. This led to producing and introducing improved seed potatoes at an affordable price through a public private partnership (PPP). Interviews with experts and a survey of local producers were carried out to identify factors influencing the success of the partnership.

A Service, Training and Innovation Center (STIC) has been created to produce the first clean potato seeds in Africa on a commercial scale, based on cultivation of in vitro potato plantlets and aeroponics to produce mini-tubers. It is called Seed Potato Advancement Centre, an education–enterprise partnership, using these plantlets to produce mini-tubers through aeroponics. Seed multipliers are responsible for the next three stages of seed multiplication. The final product is the certified potato, sold to ware potato farmers. The availability of disease-free seed potatoes in Rwanda gives a boost to the potato value chains and contributes to food security. The partnership was successful because of the support from the government and donors, with the private sector and the extension services helping to implement the innovations effectively.

The limitation is that the number of experts interviewed is limited and the survey did not only deal with potato-related activities. The focus is on one region only, but the most important potato growing area in Rwanda.

STICs function as a tool for cooperation between government, private sector and the knowledge sector to achieve commercial and development goals. They function as a channel for technology transfer. They allow applied research, including agronomic research; information collection; and dissemination, networking, training, organization of outreach activities. The model can be repeated in other sectors and countries.

The paper looks at a PPP in agriculture with educational institutions. Second, the Triple Helix and value chain literature is used to study the introduction and implementation of appropriate innovations, while factors determining the success of the partnership were identified. This concerns the first production of clean seed potatoes in Africa on a commercial scale.

The purpose of this article is to investigate on changes of the microbial load and the chemical and physical properties of date fruits stored for 6 months under two different temperatures.

A composite sample of 100 kg date fruits from the Khalas variety, season 2019, was collected from the local market in Al Ahsa Province, Saudi Arabia, packaged in 1 kg lots, stored at room and refrigerator temperatures and the microbial contamination and the chemical and physical properties monitored over a period of six months of storage. Total bacteria, lactic acid bacteria, Enterobacteriaceae, yeasts and molds were counted and representatives of yeast and mold contaminants were identified using morphological, physiological and molecular typing techniques. Changes in the color and texture of the samples were also monitored during storage.

The yeasts detected were two strains of each of Lachancea thermotolerans and Rhodosporidiobolus fluvialis and one strain of Cystofilobasidium lacus-mascardii. For molds, one strain of each of Aspergillus niger, Aspergillus flavus, Penicillium chrysogenum and Aspergillus caespitosus have been detected. No significant growth of these microorganisms was observed, but enough load persisted during storage that makes the samples not meeting the microbiological standards. There were significant changes in the color and texture of the fruits during storage.

These findings add important information that can help producers and processors to improve quality and promote marketing of date fruits, especially to international markets.

The application of global indices of nutrition and food sustainability in public health and the improvement of product profiles has facilitated effective actions that increase food security. In the research reported here we develop index measurements further so that they can be applied to food categories and be used by food processors and manufacturers for specific food supply chains. This research considers how they can be used to assess the sustainability of supply chain operations by stimulating more incisive food loss and waste reduction planning. The research demonstrates how an index driven approach focussed on improving both nutritional delivery and reducing food waste will result in improved food security and sustainability. Nutritional improvements are focussed on protein supply and reduction of food waste on supply chain losses and the methods are tested using the food systems of Kenya and India where the current research is being deployed. Innovative practices will emerge when nutritional improvement and waste reduction actions demonstrate market success, and this will result in the co-development of food manufacturing infrastructure and innovation programmes. The use of established indices of sustainability and security enable comparisons that encourage knowledge transfer and the establishment of cross-functional indices that quantify national food nutrition, security and sustainability. The research presented in this initial study is focussed on applying these indices to specific food supply chains for food processors and manufacturers.
