Paradox, Image, and Sustainability: Using Art and Aesthetic Experiences to Explore Ethical Challenges in the Global Agriculture and Food Industry

The global food industry is a useful domain for examining ethical challenges and exploring paradoxes. The authors make the case for the use of art, design, and aesthetic experiences to provoke students to see the world differently and take action. Issues of consumer consciousness, cultural identity, environment, politics, and the growing separation from the developed and less developed countries are considered with suggested activities to bring these to life. The paper offers suggestions for future research, teaching ideas, and a set of food industry resources for the classroom.

Unexpected Events in Food Production are the New Normal? Results of an Industry Survey on Factors, Influencing Resilience in Food Production and Food Value Chains

In this paper, resilience is defined as the ability of food production entities to respond to, withstand and learn from short-term shocks and long-term stresses. Little ist known about the resilience in the food production sector. There also is a lack of information on which resilience measures companies see the greatest need for investment. Therefore, the focus of the explorative survey was to gain insight into current challenges and influences on the resilience of primary food producers and food processors, to identify topics for resilience management and related gaps. Representatives from 84 companies in food production in Germany responded on topics of resilience, including factors that influence product safety and availability of machinery, status of preparation for disruptive events and possible measures to improve resilience. The responses collected were analyzed descriptively. The results showed that most companies believe that they are not well prepared for disruptive events and that they require measures to improve their resilience. Most indicated that organizational factors such as the company’s production capacity or the availability of raw materials, among others, have a particular influence. Every second primary food producer plans to adapt or optimize machinery and equipment as a resilience improvement measure. While slightly more than half of the respondents from the food processing sector implement measures for information procurement and training, or intend to implement such measures in the future. This area is seen as the most important aspect for improving resilience by respondents from primary food production. Overall, it also became clear that there is a need for tools to assess and evaluate resilience.

Impact of Differences in Type of Primary Packaging on the Shelf Life of Javanese Grasshopper (Valanga nigricornis Burm.) Snack Bars

One of the processed products from Javanese grasshopper (Valanga nigricornis Burm.) flour that is being developed is snack bars. This product was designed to introduce processed Javanese grasshopper flour (JGF) products with high protein content to consumers. However, the shelf life of the grasshopper snack bar and the best type of packaging to store the product are not yet known. This research aimed to determine the shelf life of Javanese grasshopper snack bars packaged in three different types of packaging and to identify the most effective packaging for these products. The three types of packaging chosen were plastic packaging in the form of a standing pouch (SP), aluminium foil packaging without folds (alufo), and aluminium foil packaging with folds (alumina). This research used the accelerated shelf life testing (ASLT) method with the Arrhenius approach. The parameters measured were moisture, fat, and water activity (aw) content during eight measurement periods with three different storage temperatures (20oC, 30oC, 45oC). There were differences in estimated shelf life based on parameters for each type
of packaging. The shelf life of Javanese grasshopper snack bar products based on packaging type and estimation parameters varied from 0.68 months to 14.81 months. The best parameter to estimate shelf life was the fat content in the alufo packaging, which had the highest R2 value from the order 1 equation in the Arrhenius method with a value of R2 0.999. The shelf life of the Javanese grasshopper snack bar product estimated by measuring the fat content parameters on the alufo packaging was 14.81 months if stored at a temperature of around 30oC.

Effect of Ratios of Tilapia Trim Meat and Fermentation Periods on Quality Characteristics of Fermented Fish Sausage

Using tilapia trim meat (TTM), a by-product from industrial-scale tilapia fillet manufacturing, for production of fermented fish sausage (FFS) may increase the benefit to the tilapia filleting industry by selling this new product to consumers. Six ratios of TTM:tilapia fillet meat (100:0, 80:20, 60:40, 40:60, 20:80 and 0:100) were used for sausage production. FFS samples prepared with each ratio were collected on days 0, 2, 4 and 6, and analyzed for quality parameters including lactic acid bacteria (LAB), total plate count (TPC), yeast and mold (YM), texture profile analysis (TPA), CIE color values (L*, a* and b*), pH, titratable acidity and sensory acceptability. The ratio of TTM to tilapia fillet
meat had no effect on YM, b*, pH and titratable acidity. The 0:100 ratio produced lower LAB, TPC and L* values compared to 100:0, 80:20 and 60:40. The ratio also yielded a higher a* than 100:0 and 80:20. The 0:100 ratio generated the best TPA, followed by 20:80. However, these two ratios were not significantly different concerning sensory acceptability. The 20:80 ratio, giving similar sensory quality to 0:100, is recommended for the production of FFS. The results also reveal that FFS ripened on day 2 and ratios of TTM:tilapia fillet meat did not affect the ripeness of the product. The best quality of FFS was found on day 4.

Development and Characterisation of Fortified Yogurt with the Addition of Carrot Peel and Celery Peel as By-Products from the Vegetable Industry

Developing products that meet consumer expectations can be a challenge for researchers. Yogurt is a palpable dairy product because it is versatile and can be eaten as a dessert and snack. The present work aims to develop a yogurt with the addition of carrot peel and celery peel to satisfy the current market requirements by reintegrating some vegetable by-products in the technological process of making yogurt but also to replace protein additives, which have the role of improving the rheological characteristics and sensory properties of yogurt. In this sense, a comparative analysis was made between yogurt with addition, classic yogurt, and yogurt with powdered milk. A non-numerical multi-criteria multi-personal agreement method described by Fadhil and collaborators was used to perform the sensory analysis (Fadhil et al., 2021). Physicochemical analysis of the samples was performed during a storage period of 18 days on the first day, the ninth day and the eighteenth day. The pH, titratable acidity, syneresis, water holding capacity and lactose content of the samples were measured. The results indicate an improvement in the degree of syneresis and the water retention capacity, especially in the second part of the storage time, of the yogurt with the addition of celery and carrot peels, compared to the other two samples. The evaluated sensory characteristics obtained better scores because the carrot and celery peels brought a unique flavor to the product.
