Description:

We conducted experiments on winter wheat grown in copper-deficient soil, where soil tests revealed a more pronounced deficiency in the deeper layers. As climate change reduces precipitation, plants increasingly rely on nutrients from these deeper layers. A copper–sucrose complex—previously unused in agriculture—was applied as a foliar spray during the tillering and flowering stages. Across the three-year average, significant increases were observed starting from the 1 kg ha−1 copper dose in yield, from 0.3 kg ha−1 in crude protein content, and from 0.5 kg ha−1 in wet gluten content compared to the untreated control. For all three parameters, the highest values were achieved with the 2 kg ha−1 dose. Yield increased by 1.03 t ha−1, crude protein by 0.9%, and wet gluten by 2.3% relative to the control. In 2019, high humidity and favorable temperatures during flowering led to fungal infections in control plots, with DON toxin concentrations exceeding the regulatory safety threshold. Following copper–sucrose complex application, DON levels dropped below this threshold, demonstrating a measurable protective effect.

Description:

The growth of the world's population is an increasing challenge for agricultural production. Improving soil productivity is the key to ensuring the quantity, quality and safety of food for a growing population. In addition to macroelements, microelements also play an important role in the biochemical processes. A large percentage of soils in Hungary show a deficiency in copper. For three years, we treated the leaves of winter wheat with a copper-tetramine-sulphate complex derived from microelectronic waste. Aim to provide an alkaline pH range of 9.3 for effective foliar treatment. Treatments were applied on 10 m2 small plots at 0; 0.1; 0.3; 0.5; 1.0; and 2.0 kg×ha-1 copper dose in the budding and flowering phenological stages with copper-tetramine-sulphate produced from microelectronic waste. After harvesting the crop from the plots, the yield, raw protein, and gluten content were measured. In the copper-deficient soil, a significant increase in yield and protein and gluten levels was observed after treatment with copper foliar fertiliser. The most significant increase in yield was obtained in the treatment at flowering (0.40 t/ha), with a 0.37 % increase in crude protein content and a 1.95 % increase in wet gluten content.

Description:

Background: Fermentation is a sort of biotechnology that uses microorganisms to produce animal food through chemical process. In ancient times, wastes were treated with chemicals, but now companies convert wastes to valuable food, food ingredients or feed products such as single cell oils or single cell protein. The most used substrate is molasses and corn steep liquor which is a part of the fermentation process. Aim: The aims of the manuscript is to provide an overview of the yeast strains and food by-products used in production of single cell proteins by fermentation process. Furthermore, the manuscript summarizes the role of single cell protein in animal feed. Methods: Electronic searches were conducted on Google Scholar database Medline and PubMed. A further search was conducted on the Food and agricultural organization FAO research article database. Results: Single cell protein produced by these substrates and different microorganisms (algae, yeast, bacteria) play an important role in animal feeding. Furthermore, SCP is a high-quality protein, unsaturated fatty acids, vitamins and minerals sources for animals. Conclusion: Production of single cell of protein through the fermentation has several significant benefits including sustainability, health and production efficacy.

Publication Name: Pharmanutrition

Publication Date: 2022-03-01

Volume: 19

Issue: Unknown

Page Range: Unknown

Description:

Background: Malnutrition is a serious condition that develops when the human body is deprived of or does not obtain the right amount of vital nutrients like vitamins, minerals, proteins, carbohydrates, lipids and some other essential substances that the body needs to function. It can have a significant impact on people's health including stunted growth, low body weight and muscle wasting. Purpose: This study is aimed to determine the factors that could cause malnutrition in humans, something that is considered as a major global issue nowadays and is associated with negative aspects on patient's activities. Methods: Electronic searches were conducted on the Google Scholar database, Medline and PubMed up to the 11of December 2021. All studies reporting an association between foods and malnutrition were included. Results: The search yielded 637 references, included 52 clinical trials, 11 meta-analysis, 45 randomised clinical trials (RCT) and 201 reviews. Among the manuscripts, 25 studies provided evidence for the association between malnutrition and micronutrients. The results showed that in addition to insufficient intake of the essential nutrient, several chronic diseases including gastrointestinal tract diseases, cancer and sometimes post-surgery complications are also associated with malnutrition. Conclusion: Only a limited number of studies reported a direct link between functional foods and malnutrition, which all agree that there is clear evidence in favour of functional foods being effective in preventing and reducing the impact of malnutrition. Other studies looked at for this review would suggest that they may even be effective in improving the quality of life.

Description:

Worldwide, and also in Hungary, more and more patients are diagnosed with inflammatory bowel disease (IBD) each year. In the case of IBD patients, to supplement a normal diet, alternative solutions, such as, for example, the dietary use of single cell proteins intended to be examined by us are required. Ensuring the proper nutrition and liquid supply of the human body is one of the major tasks of modern food science. By using state-of-the-art scientific knowledge and diagnostic methods, the energy requirement of people with increased energy and protein needs can be determined as a function of their body weight, and the production processes of foods should be realized with this information in mind. In our research, single cell proteins (SCP) have been produced in a yeast culture grown on high sugar content culture media, including their nutritional evaluation. Possibilities for incorporating SCP in the diet of IBD patients have also been investigated. With our research results, we would like to provide assistance to specialists in food science and those in nutrition science contributing to food production.
