Effect of different storage conditions on physicochemical and bioactive characteristics of thermally processed stingless bee honeys

Impact of prolonged storage on quality assessment properties and constituents of honey: A systematic review

This systematic review paper aims to discuss the trend in quality assessment properties and constituents of honey at different storage conditions and confer the possible whys and wherefores associated with the significant changes. Initially, a literature search was conducted through Google Scholar, ScienceDirect, PubMed, and Scopus databases. In total, 43 manuscripts published between 2001 and 2023 that met the inclusion and exclusion criteria were chosen for the review. As an outcome of this review, prolonged honey storage could deteriorate sensory, nutritional, and antioxidant properties and promote fermentation, granulation, microbial growth, carcinogenicity, organotoxicity, and nephrotoxicity. This systematic review also recognized that diastase activity, invertase activity, 5-hydroxymethylfurfural content, proline content, sugar content, amino acids, and vitamins could be used as indicators to distinguish fresh and stored honey based on the significant test (p-value) in the reported studies. However, all the reported studies used the simplest approach (one-way ANOVA) to identify the significant differences in the analyzed parameter during the storage period and none of them reported an approach to identify the most influential parameter at different storage conditions. In conclusion, orthogonal partial least squares discriminant analysis (supervised multivariate statistical tool) has to be employed in future studies to find the most influential parameter and could be used to potent chemical markers to distinguish fresh and stored honey because this analysis is incorporated with S-plot, variable importance of projection, and one-way ANOVA, which can produce the most accurate and precise results rather solely depending on one-way ANOVA.

The Importance of Testing the Quality and Authenticity of Food Products: The Example of Honey

The aim of this study was to review methods of honey testing in the assessment of its quality and authenticity. The quality of honey, like other food products, is multidimensional. This quality can be assessed not only on the basis of the characteristics evaluated by the consumer during purchase and consumption, but also on the basis of various physicochemical parameters. A number of research methods are used to verify the quality of honeys and to confirm their authenticity. Obligatory methods of assessing the quality of honey are usually described in legal acts. On the other hand, other, non-normative methods of honey quality assessment are used worldwide; they can be used to determine not only the elementary chemical composition of individual types of honey, but also the biological activity of honey and its components. However, so far, there has been no systematization of these methods together with a discussion of problems encountered when determining the authenticity of honeys. Therefore, the aim of our study was to collect information on the methods of assessing the quality and authenticity of honeys, and to identify the problems that occur during this assessment. As a result, a tabular summary of various research methods was created.

Potential of Natural Honey in Controlling Obesity and its Related Complications

Honey has a long history of therapeutic properties for multiple diseases, including inflammation and oxidative stress. This review aimed to provide a better understanding and renewed interest in the potential role of honey in obesity control, obesity-related diseases treatment and weight management, with specific reference to its components and the effect of honey overall. There is compelling evidence that honey possesses the desired properties for this purpose, as seen in the in vitro, in silico, in vivo and clinical analyses discussed in this review. This review also highlights the components potentially responsible for the health benefits of honey. Honey and its components reduce blood sugar levels, improve insulin sensitivity and lipid metabolism by reducing triglycerides, and reduce total cholesterol and LDL levels while increasing HDL levels that prevent excessive weight gain and reduce the risk of obesity and its complications. Further controlled studies are necessary to validate the role of honey in the management of obesity, both as a preventive and as a therapeutic agent.

Stingless bee honey: An overview of health benefits and main market challenges

This review aimed to evaluate the nutraceutical and medicinal effects of stingless bee honey (SBH) by bringing a discussion focused on the main known in vitro/in vivo health-promoting effects. SBH has a high-water content, slight sweetness, acidic flavor, fluid texture, and slow crystallization. The type and concentration of phenolic compounds and consequent antioxidant activity were mainly associated with the floral sources, geographical location, bee species, and processing steps. SBH has anti-inflammatory, antimicrobial (against spoilage and pathogenic microorganisms), anti-diabetic, and skin aging delay activities in in vitro tests. It has also shown antioxidant and hypolipidemic effects, can protect from injuries caused by dyslipidemia, possess anti-inflammatory activity against chronic subclinical systemic inflammation and anti-diabetic properties, and can control and prevent Staphylococcus aureus infection on infected wound healings in in vivo tests (rats). However, clinical trials are crucial for the probation of the medicinal and nutraceutical properties of SBH. Despite this, there are still no general norms and/or quality standards for this type of honey. The information summarized in this review is important to add value to this little-consumed food, providing helpful information to spread knowledge about its benefits, assisting future studies, and raising perspectives for its recognition as a functional food. Furthermore, it may encourage the creation of standard quality for the production and marketing of SBH. PRACTICAL APPLICATIONS: Previous studies have already summarized the chemical profile and physicochemical properties of stingless bee honey (SBH) and its potential health properties. However, no study has performed an overview of the potential nutraceutical and medicinal effects of SBH, presenting results from in vitro and in vivo investigations. Therefore, this review is the first study to overview the potential nutraceutical and medicinal effects of SBH, showing results of in vitro/in vivo health-promoting effects. The bioactivity of SBH is related to bee species and floral sources. The SBH has anti-inflammatory, antimicrobial, anti-diabetic, and antioxidant in vitro activity. It has also shown hypolipidemic effects and protection from injuries caused by dyslipidemia in rats.
