Voltammetry is an electrochemical technique widely used in quantitative analysis to determine nickel ions in food samples due to its excellent stability. Knowing the exact applied levels of metals such as nickel in different food samples is very important to prevent high nickel consumption, especially in people with allergies and nickel excess. Electrochemical analytical methods appear to be an alternative with many advantages, including high sensitivity, low detection limits on the g/L scale, ease of use, and sim...

The benefits of using biopolymers in the food industry have motivated the scientists to develop products with better characteristics than the regular ones. Biocompatibility with the human body, edibility and ease of use have paved the way for biopolymers such as agar, sodium alginate, carrageenan, chitosan, etc. for using it in the biomedical and pharmaceutical industries. In addition to their well-known characteristics, biopolymers have the ability to incorporate various natural substances, representing an almost...

Nowadays, the food supplement industry has grown considerably, mainly due to the orientation of consumers towards more natural products. In Romania, the Institute of Food Bioresources notified over 900 food supplements in 2020 and over 1500 in 2019. Unfortunately, the use of these supplements, although healthy, is problematic due to environmental pollution. The packaging used, often disposable, is highly polluting, multilayer, difficult to sort and impossible to recycle. This paper presents a viable option for pac...

Detection of nickel ions in various foods, especially fruits, is very important for the prophylaxis of patients with allergic contact dermatitis to this heavy metal. Currently, there are a limited number of rapid methods for identifying nickel ions, so it is necessary to develop new biosensors in this area, by improving selectivity of ligands and utilization of immobilization elements suitable for nickel ions. The mentioned elements are very important because they can increase the selectivity, sensitivity and can ...

The packaging of a food product is an extremely important step in its path from development to the final consumer. The packaging has important functions: preservation and protection of packaged products, handling, storage and transport, as well as promotion. Most consumers choose a product based on its packaging, so we can say that it is the business card of a product. But because the consumer has refined his preferences and become more and more attentive to what he buys, the industry is looking for solutions to c...

In recent years, the ultrasonic field has gained the attention of several authors in the area of employing it to process and interact with fruit juices as a viable alternative to the use of conventional processing technologies. The ultrasound technique main advantage, as a non-thermal treatment, is its ability to maintain juice quality whist enhancing the juice homogenization level. The aim of this study was to subject the sea buckthorn juice to ultrasonic field treatment in order to improve the its pulp stability...

Wet ageing is the most commonly used ageing sistem by the meat industry to improve tenderness, which results in a more homogeneous product with high consumer acceptability. The aim of this study is to determine the influence of wet ageing duration on beef quality characteristics, at refrigeration temperatures (0 - 5пїЅC). The meat samples were kept under refrigeration conditions for 2, 7, 12, 17, 21 days. After each period, there were monitored: the textural parameters (hardness, adhesiveness, springiness, cohesiv...

Sea buckthorn (Hippophae rhamnoides L.) has gained worldwide researchers attention as a unique and valuable plant, primarily for its medicinal and nutritional potential. The berries can be capitalized by their processing in order to obtain derived alimentary products such as, e.g. juice and jam, as well as used for flavoring of dairy products. The dried sea buckthorn berries and leaves are used for tea. Lately, due to the fact that consumers are more open to information, so their level of awareness is higher, ther...

Yogurt is widely consumed as functional food because of the good taste and nutritional properties (rich in potassium, calcium, protein and vitamins), being an excellent vehicle to deliver probiotics to consumers. However, its enrichment with various physiologically active ingredients could provide specific health benefits beyond basic nutrition. The reason for incorporating the sea buckthorn powder (SBP) in yogurt was to enhance its functionality, considering the sea buckthorn content in non-digestible oligosaccha...
