The aim of the study is to examine dietary habits, onset and course of the disease as well as the quality of life of patients with LPR. EXPERIMENTAL APPROACH: The results of the modified food frequency questionnaire (FFQ-m) and laryngopharyngeal reflux health-related quality of life (LPR-HRQL) questionnaires were compared between subjects with and without LPR...

RESEARCH BACKGROUND: Wine production, which is considered a major sector in food industry, often involves the use of a large amount of resources. Moreover, wine making generates a large amount of grape pomace, which is generally used for low-value applications such as fertiliser and animal feed. The aim of the present research is to explore the possibility of improving the overall sustainability of traditional winemaking. EXPERIMENTAL APPROACH: A zero-waste process was developed...

RESEARCH BACKGROUND: Heat-stabilised defatted rice bran (HSDRB) is a primary by-product of rice bran oil extraction industry and a nutritious source of protein. However, despite the unique nutritional profile of rice bran protein, the protein-rich by-product, HSDRB is underutilised as a low-value animal feed. Research on protein extraction from HSDRB by enzymatic hydrolysis has attracted the attention of numerous scientists. However, a cost-effective extraction method is required to mitigate the high costs associated with the use of enzymes...

RESEARCH BACKGROUND: The consumption of whole grain cereal flour contributes to increased intake of dietary fibre and phenolic compounds beneficial to human health. However, whole grain flour also has some disadvantages, such as poor baking properties and lower technological quality. Applying ultrasonic and hydrothermal treatments can provide new opportunities to modify and improve the baking and biofunctionality of flour as well as the quality of baked goods. EXPERIMENTAL APPROACH: The whole grain flour samples of six wheat varieties with different amylose content were studied...

RESEARCH BACKGROUND: One of the issues in the production of fish sauce is the legal constraints on the concentration of histamine produced by bacteria during fermentation because it causes allergic reactions in humans. The goal of this study is therefore to eliminate histamine from the final product after fermentation to enhance the quality of fish sauce for consumer safety, manufacturer exportability and domestic sales. EXPERIMENTAL APPROACH: The bacteria that grow in the histamine medium were isolated from the salted fish...

RESEARCH BACKGROUND: Herbs and spices used in traditional medicine are nowadays increasingly used in combinations to create functional food formulations aimed at treating specific symptoms and disorders. Among herbs originating from the Mediterranean region, extracts of myrtle ( Myrtus communis L.), bay leaf ( Laurel nobilis L.) and fennel ( Foeniculum vulgare Mill.) are traditionally used for gastrointestinal disorders. When considering how to incorporate these extracts into products, dairy-free milk alternatives provide an excellent base with almond-based drinks being among the most popular within this group...

RESEARCH BACKGROUND: A few studies have investigated Cynara scolymus enzymes as a substitute for calf rennet in cheese making. They used aqueous extracts prepared by maceration of plant material and stored by freezing. However, it was indicated that lyophilisation is a better alternative to preserve the coagulant properties of plant extracts over a longer period of time, as it is a more controllable, stable and hygienic alternative with a better shelf life that is easier to transport, store and standardise...

RESEARCH BACKGROUND: Protein A affinity chromatography is a well-established method currently used in the pharmaceutical industry. However, the high costs usually associated with chromatographic separation of protein A and the difficulties in continuous operation make the investigation of alternative purification methods very important. EXPERIMENTAL APPROACH: In this study, extraction/back-extraction and precipitation/dissolution methods were developed and optimised...

RESEARCH BACKGROUND: There is an increasing interest in foods with added nutritional value. This study presents the opportunity for the reformulation of muffins using chia seeds and lyophilized peach powder in view of the emerging societal challenges regarding unhealthy eating patterns and food intolerances. EXPERIMENTAL APPROACH: Two new formulations were developed to eliminate the use of eggs and alter the flour content and type. Physical characteristics, texture analysis, water activity, microbial load, antioxidant potential and sensory profile aided in the evaluation of the newly developed products...

RESEARCH BACKGROUND: Teff [ Eragrostis tef (Zucc.) Trotter] is an underutilised cereal crop grown mainly in Ethiopia and Eritrea. It is an excellent source of dietary fibre, vitamins, minerals and bioactive compounds. However, it also contains a high amount of phytic acid, which is an antinutrient and reduces the bioavailability of minerals and proteins. To improve the nutritional quality of teff, the phytic acid content should be reduced by an effective dephytinisation method. EXPERIMENTAL APPROACH: In this study, various dephytinisation methods (fermentation, autoclaving and phytase treatment) were used to dephytinise teff flour...
