1. THE INFLUENCE OF STORAGE TEMPERATURE ON THE WEIGHT OF GOLDEN DELICIOUS APPLES

Author(s):

S. Kassebi, P. Korzenszky

Abstract: The great majority of customers choose nutritious, fresh fruit with a distinct color for human ingestion. The Golden Delicious apple is a popular yellow-colored, delicate, sweetish, somewhat acidic, crisp-fleshed, juicy, fragrant, and aromatic apple. Apples, like other fruits, are stressed throughout their development and growth in the field, as well as during harvest and the postharvest environment (processing, storage, transportation). The refrigerated system enables bulk processing of food goods from harvest to market, guaranteeing that freshness and integrity are preserved for a prolonged time through precise temperature and humidity regulation. This study looked at the effects of three months of storage on the weight loss of Golden Delicious apples, both under refrigerated settings at 5±0.5°C and 82% relative humidity and in controlled ambient conditions at 25±0.5°C relative humidity and 60% relative humidity. The results showed that the weight loss in the two groups of apples was different. Apples held in cold storage lost 3.31g to 4.59g of weight; meanwhile, apples stored at room temperature lost 23.29g to 31.76g of weight.

Keywords: Golden Delicious apples, storage, weight loss, shelf life, temperature


2. CIRCULAR CHARACTERISTICS OF ORGANIC FOOD CONSUMPTION, NEW CONSUMPTION TRENDS IN HUNGARY

Author(s):

Cs. Fogarassy, E. Berecz

Abstract: Consumers have an important role to play in the transition to a circular economy by making more sustainable decisions and further supporting the functioning of value groups through their consumer choices. To this end, it is necessary to promote circular and sustainable policies and practices that can lead to the emergence of demonstration initiatives. From the theory of the circular economy and the sustainability literature, 10 groups of factors can be identified that can influence the acceptance of circular products and services for consumers. None of the aspects were specifically related to the consumption and recycling of organic food. Food supply systems are identified as a potential area for the implementation of circular concepts; however, these concepts focus mainly on food production and the recycling of surplus food. Current circular solutions place less emphasis on food-related consumption, separating it from production or waste streams. In the next study, we would like to demonstrate that consumption trends have surprisingly overlapped in recent years (during Covid), resulting in a generational change in the consumption of organic food. And the clear driving force of this change is circular thinking and gaining preferences.

3. MODELING THE EFFECT OF WHEEL TRAVELING ON THE SOIL SURFACE ON THE LOAD OF BURIED STRUCTURE

Author(s):

I. Keppler

Abstract: As a result of the technical development of agriculture, machines with very high axle loads appeared in the fields and on farm roads. As a result, subsurface soil pressure values will also increase, which will ultimately put increased stress on underground pipelines and other structures. In our paper, we show the possibility of modelling the problem using explicit dynamical methods by means of a simple example.
