Antioxidant, Antimicrobial and Physicochemical Properties of Beef Sausages Enriched with an Aqueous Extract of Senduduk (Melastoma malabathricum L.) Leaf
The use of natural products in sausages has become a new trend for health reasons. A natural product that could be incorporated into sausages is an extract of the senduduk (Melastoma malabathricum L.) leaf. Senduduk is an abundant shrub herb in Indonesia. This kind of plant is mostly used as a traditional medical remedy and as an ingredient in some culinary recipes. This study was carried out to investigate the effect of an aqueous extract of senduduk leaf (SLE) on the antioxidant, antimicrobial and physicochemical properties of beef sausage. Four treatments were used: ingredients consisting of beef, vegetable oil, skim milk, tapioca, salt, phosphate, ice cubic, garlic, pepper, dan nutmeg as a Control; the Control ingredients plus 0.01% of butylated hydroxytoluene (BHT); the Control ingredients plus 0.83% of SLE (SLE-1), and the Control ingredients plus 1.1% of SLE (SLE-2). All ingredients of each formula were homogenously blended and the sausage mix was cooked. The addition of BHT and SLE affected the proximate composition, with the moisture content decreasing as the duration of chilled storage increased. The addition of SLE lowered the pH and aw value and both tended to increase during chilled storage. SLE also enhanced the WHC of the sausages which increased in value during chilled storage. The addition of BHT and SLE could increase the antioxidant activity of the sausages as indicated by scavenging DPPH free radicals. SLE in sausages could inhibit microbial growth during chilled storage. It can be summarized that the addition of an aqueous extract of senduduk could improve the physicochemical, antioxidant and antimicrobial properties of beef sausages.

Value propositions for improving the competitiveness of short food supply chains built on technological and non-technological innovations
There has been growing consumer demand for the products and services of the short food supply chains (SFSCs) in recent times. A procedure was developed to identify the technological and technological innovations that can improve the performance and competitiveness of the SFSCs. The needs of the SFSCs for innovative solutions were collected by interviewing 18 SFSCs from 9 countries. An inventory was prepared to contain 136 technological and non-technological innovations, meeting these needs. The innovations were collected from the good practices of the 18 SFSCs, experiences of the project partners and state of the art. The success factors and bottlenecks of each short food supply chain operation and their current value propositions were identified. From the inventory, those innovations were selected for each short food chain case study which can be applied to eliminate or reduce the bottlenecks or enhance the success factors leading to new, upgraded value propositions with increased added value for the consumers. The new, upgraded value propositions can serve as a starting point for developing a strategy for improving the competitiveness of a short food chain organisation through the application of innovations.

Handling Practices and Quality Attributes Along the Supply Chain of gboma (Solanum Macrocarpon): A Leafy Vegetable in Southern Benin
gboma is a leafy vegetable commonly consumed in Benin, which plays an important role in food security. This study assessed the handling and preservation practices as well as quality attributes of gboma along the supply chain in Southern Benin. A survey among 785 people (285 producers, 180 whole salers/retailers, and 326 consumers) living in four Departments of Benin was conducted to evaluate the consumption frequency, the transportation mode, the preservation methods and quality attributes of gboma during purchasing. The survey revealed that, in general, gboma sauce is consumed twice to three times a month in all the departments covered. Different practices, including humidification, were used to preserve the leaves during selling. Traditional baskets or old clothes were used for the transportation and storage of gboma. Important quality attributes mostly used by actors during purchasing were freshness and color followed by physical damage and, to a lesser extent, weight and leaf surface at different degrees. gboma is currently sold in informal markets; however, improving handling and selling practices could preserve the freshness of this leafy vegetable that could then be placed in conventional supermarkets. Thereby, the selling and consequently the production level will increase, with positive impact on the income of producers.

Optimization of bromelain isolation from honi pineapple crown
Bromelain is a proteolytic enzyme that can be found in all parts of pineapple plant varieties. Pineapple crown (PC) has higher bromelain activity than other pineapple wastes such as peels and leaves. This study isolated bromelain from one variety of PC, namely Honi, and determined the optimum drying temperature as well as concentration of ammonium sulphate to obtain the best bromelain characteristics such as protein content, unit activity and specific activity. Honi PC was dried at various drying temperatures (35, 40, 45, 50, and 55 °C), and then extracted and purified using ammonium sulphate in various concentrations (20, 40, 60, and 80%), in order, to get bromelain. Furthermore, the yield of isolated bromelain was calculated and the protein content, unit activity and specific activity of bromelain characterised. The highest yield of crude bromelain (CB) was achieved at 35 °C. However, the highest protein level, unit activity and specific activity of CB were achieved at 55 °C (p < 0.05). Purification of CB using concentrations of ammonium sulphate in the range 40 to 80% resulted in a higher protein level (p < 0.05). The highest unit activity and specific activity of bromelain were achieved at a 60% concentration of ammonium sulphate (p < 0.05). 55 °C and 60% were the optimum drying temperature and concentration of ammonium sulphate respectively to achieve the best characteristics (2.16% protein level, 1.61 U/mL unit activity and 0.75 U/mg specific activity) for bromelain isolated from Honi PC. Honi PC isolated bromelain was shown to inhibit the browning reaction on apple fruits. The agroindustry waste product, Honi PC, has potential as a future alternative bromelain source.

Drinking coffee may reduce chances of developing Alzheimer’s disease: systematic literature review and meta-analysis
Coffee is a popular beverage, and it contains caffeine, a psychoactive substance. Consuming coffee may reduce the risk of developing Alzheimer’s disease (AD). However, the association between the reduced risk of developing AD and the consumption of coffee is controversial. Therefore, we conducted a systematic literature review and quantitative synthesis meta-analysis that included dose-response analysis on the relationship between the consumption of coffee and the risk of developing AD. Based on PRISMA guidelines, we analysed standard databases of journals published between January 1999 and May 2020. We included the two population-based cohort studies and one case-control study. All studies included looked at the association between consuming many cups of coffee, the amount of coffee consumed in milligrams per day and the risk of developing AD. The systematic literature review and meta-analysis had 1670 participants with follow-up years that ranged from 5 to 21. The consumption of moderate or 3-5 cups per day reduces the risk of developing AD. The pooled relative risk and 95% confidence interval of the 3 included studies were 0.63 (0.3, 1.54). Dose-response curve analysis appears to be U-shaped. The results of the forest plot showed that there is low heterogeneity between the studies. Plotting the funnel plot and the Galbraith plot demonstrated publication bias of the three included studies. More prospective and long-term studies have to be conducted in other countries to determine the exact risk of developing AD.

Understanding social innovation in short food supply chains: an exploratory analysis
Short food supply chains (SFSCs) are alternative food chains that have gained ground and contribute to the global food system's sustainable transition. To explore how to enhance their capacity to act and benefit society at large, we turned to scholarly and policy work on Social Innovation (SI). We concentrated on understanding what SI in SFSCs is and how it may stimulate their potential, following a two-phase approach. In Phase 1, employing a two-step systematic literature review, we generated a rich database of SI definitions, but no suitable definition was found. We proceeded to craft a domain-specific systems-centred definition, positing that SFSCs can be seen as social living systems, while SIs in SFSCs may be seen as processes that bring about change (e.g., new mentalities) and result in the creation of sustainable value for the actors involved and beyond. With the aid of an additional scholarly review, we also determined that the drivers of SI that matter are those that secure actor engagement in the co-design and co-development stages of SI (e.g., training). In Phase 2, we attempted to empirically validate the findings from Phase 1 in 12 Community of Practice (CoP) events in nine European countries. We found partial support for the SI definition, strong support for the vital role of trust, and concluded that, in any SFSC, it is critical to have a group of dedicated actors that have realized their role as (co-)leaders in co-shaping their own future.

Views of Food Stakeholders on Packaging Factors
Packaging has an enabling role in supply chains (SCs) as it facilitates a range of functions, specifically (i) marketing; (ii) logistics and SC management; (iii) food technology; and (iv) environmental protection. This study explores the appreciation towards certain food packaging factors and attributes by consumers and industrial experts for a range of food product types. Primary data was collected through a questionnaire in the Greek market and then analysed using a 1-way ANOVA and the Tukey test. The study findings reveal that food SC stakeholders mainly appreciate packaging attractiveness. Other attributes that promote environmental sustainability and facilitate logistics operations were of high importance as well.

An online innovation platform to promote collaboration and sustainability in short food supply chains
A sustainable Short Food Supply Chain (SFSC) requires collaboration among all actors, which nowadays is facilitated by information and communication technologies (ICT). However, not all SFSC stakeholders network with others in this way, and it is not clear what will draw them to ICT interaction. A simple, user-friendly website, the SMARTCHAIN Innovation Platform, evolving since March 2019, may facilitate interaction and cooperation among SFSC stakeholders. This article presents the Platform's development and evaluates its efficacy and impact by analysing data from Google Analytics (GA) and other sources. Primary Platform features promote communication and information sharing: these are the 1) Innovation Hubs in 9 European countries, 2) Inventories including 150 SFSC innovations and 50 SFSC initiatives, 3) Resources databases of Publications and Weblinks, and 4) Training section. GA showed that visitors to the Platform increased slowly in the 16 months since its start, and the number of page views increased with the amount of time on the Platform. The most visited page of the Platform was the information-providing Innovation Inventory. Most Platform users were in partner countries of the SMARTCHAIN project, but not all Innovation Hubs had high numbers of users. Most users arrived at the Platform by direct link, but LinkedIn was the most important originating social network. Taken together, these data suggest growth potential for an easy-to-use website that provides useful and up-to-date information but little inclination for SFSC stakeholders to use an online Platform for communication.

Lactobacillus spp. inhibits the growth of HCT-116 and reduces IL-8 secretion by Salmonella typhimurium-infected HCT-116 colorectal carcinoma cells
Salmonella typhimurium causes symptoms resembling typhoid fever and gastroenteritis in humans. Its toxicity is due to an outer membrane consisting largely of lipopolysaccharides (LPS) which is responsible for the host immune response. The aim of this study is to evaluate the antimicrobial, anti-apoptotic ability of Lactobacillus plantarum and reduce Salmonella-induced pro-inflammatory cytokine IL-8 secretion. Adhesive tests were performed using lactobacilli co-cultured with the colon cancer cell line HCT-116 for 2 hours. The strains displaying the highest adhesion were selected for downstream 3- (4, 5- Dimethylthiazol -2-yl) -2, 5- diphenyltetrazolium bromide (MTT) tests to assess cytotoxicity. The supernatants of Lactobacillus cultured with HCT-116 cells for 24 and 48 h to evaluate the inhibitory effect. To determine Interleukin 8 (IL-8) secretion in colon cancer induced by S. typhimurium, we stimulated HCT-116 cells with S. typhimurium and co-cultured with lactobacilli for 24 h. Lactobacilli had the most significant inhibitory effects on cell growth, and their inhibitory effects were time-dependent. Strain No. 03-03-026 caused cancer cell deoxyribonucleic acid (DNA) fragmentation, and the anti-apoptosis protein (B-cell lymphoma 2) was reduced in the HCT-116 cells as determined. IL-8 production in colon cancer cells was significantly reduced by these lactobacilli. Our results suggested that lactobacilli maybe effectively reduce the numbers of S. typhimurium, IL-8 levels and the anti-apoptotic phosphorylated-p38 mitogen-activated protein kinase and B-cell lymphoma 2 proteins. Lactobacillus can be added to the diet as a food additive to prevent colorectal cancer and used to be the prophylactic agent against S. typhimurium.

Development of High-Fiber, Low Fat Chicken Nuggets
Dietary fiber intake is significantly below the recommended daily allowances worldwide, making fortification of foods with dietary fiber a vital strategy. Simultaneously, there is a trend towards increased consumption of processed meat products containing substantial amounts of fat, making processed meat products an excellent vehicle to deliver fiber. In this study, the effects of adding four types of dietary fiber (Resistant Starch (RS), Polydextrose (POD), Fructooligosaccharides (FOS) and Galactooligosaccharides (GOS)) to chicken nuggets were investigated. Fibers were added at three levels (5, 10 and 15%) to replace 33.33, 66.66, and 100%, respectively, of the chicken skin. The difference between the removed quantity of chicken skin and added fiber was compensated with water. Chicken nuggets were evaluated by measuring color, texture, proximate composition, yield and consumers’ acceptability. Results indicated that replacement of the chicken skin entirely with dietary fiber is possible without negatively affecting the final product quality.
