Quality perception throughout the apple fruit chain

Quality is considered as the main attribute for differentiating food products and/or food services. The objective of this study was to examine how different actors in the apple fruit chain perceive quality. This research included perception of quality evaluated by 38 orchards, cold storages, and retailers and 287 consumers, using two methods. Direction from the orchard to the consumer covered 'customer-supplier' method analyzing their viewpoints in different stages of the fruit chain. Backwards, from the consumers to the orchards, method employed was quality function deployment. Orchard-cold storage comparison highlighted that orchards recognize apple cultivar and yield as the most important quality attributes while cold storages focus on handling of fruit and share of first-class apples. Quality aspects important in the cold storages-retailers evaluation emphasize type of cold storage and presence of fruit defects compared to apple cultivar and ratio between quality and price. Retailer-consumer comparison showed that retailers focus on packaging and ratio between quality and price while consumers beside fruit price focus on assortment and product placement at point of sale. Quality function deployment displayed transformation of quality attributes from juiciness (consumer), advising at point of sale (retailer), apple cultivar (cold storage), to production systems at apple orchards. The results suggest that there are different views on quality by all actors in the apple fruit chain from internal quality parameter such as juiciness to production systems employed at orchards

Nanotechnology and Plant Extracts as a Future Control Strategy for Meat and Milk Products

Plant extracts, well known for their antibacterial and antioxidant activity, have potential to be widely used preservatives in the food industry as natural alternatives to numerous synthetic additives which have adverse impacts on health and the environment. Most plant compounds and extracts are generally recognized as safe (GRAS). The use of preservatives is of great importance for perishable foods such as meat and milk, which, along with their products, are commonly consumed food items globally. However, the bioavailability of plant compounds could be diminished by their interaction with food components, processing, and storage. Nanoencapsulation of plant extracts, especially essential oils, is an effective method for their application in food model systems. This technique increases the bioactivity of plant compounds by increasing their physical stability and reducing their size, without negative effects on organoleptic properties. Furthermore, a recent study showed that plant extracts act as good bioreductants for biosynthesis of nanoparticles. This so-called green synthesis method using plant extracts is a rapid, relatively inexpensive, safe, and efficient method for synthesis of nanoparticles including silver, gold, iron, lead, copper, cobalt, palladium, platinum, zinc, zinc oxide, titanium oxide, magnetite, and nickel. Some of these nanoparticles have antimicrobial potential which is why they are of great interest to the food industry. In this chapter, the nanoencapsulation of plant extracts and plant extract-mediated synthesis of nanoparticles and their potential application in order to improve the safety and quality and prolong the shelf life of meat and milk products are reviewed and discussed
