Optimization of the Spray-Drying Process for Developing Stingless Bee Honey Powder

Abstract

Response surface methodology was used to optimize the spray-drying process for the development of stingless bee honey powder. The independent variables were: inlet air temperature (110–150 oC) and maltodextrin 10DE content (50–70 % wb). The responses were powder yield, moisture, volatiles retention, solubility time, hygroscopicity, bulk loose, and hydroxymethylfurfural content. Powder moisture content, solubility time, hygroscopicity and loose bulk density were negatively affected by inlet air temperature, while powder yield, volatiles retention and hydroxymethylfurfural content were directly related. Powder yield, volatiles retention and solubility time increased with the rise in maltodextrin content, while moisture content, hygroscopicity, loose bulk density and hydroxymethylfurfural content were negatively affected by maltodextrin content. Multiple response optimization indicated that an inlet air temperature of 150 oC and maltodextrin content of 61 % wb were predicted to provide 40 % powder yield, 4.9 % wb moisture content, 71 % volatiles retention, 242 s solubility time and 232 mg/kg hydroxymethylfurfural content.

Reformulation of spray‐dried apple concentrate and honey for the enhancement of drying process performance and the physicochemical properties of powders

“…The main problem observed during drying is ‘stickiness’ that is related to the low glass transition temperature T g of sugars such as glucose (31 °C in the anhydrous state) or fructose (5 °C in the anhydrous state) that are present in the honey and fruit juices . Stickiness leads to a yield decrease, general problems with managing the process, and a low quality of finished product . To prevent undesirable changes during processing, carriers of high T g are usually applied.…”

“…13,14 Stickiness leads to a yield decrease, general problems with managing the process, and a low quality of finished product. 15 To prevent undesirable changes during processing, carriers of high T g are usually applied. In most cases, maltodextrin and gum arabic are used as carriers owing to their high solubility and non-sweet, neutral taste.…”

Multi-Criteria Optimization of a Biomass-Based Hydrogen Production System Integrated With Organic Rankine Cycle

“…The terms of "A, B, and C" refer to gasification temperature, equivalence ratio, and steam-to-biomass ratio, respectively. Generally speaking, a p-value of less than 0.05 indicates a significant term in the regression model (Cuevasglory et al, 2017). Both the gasification temperature (A) and ER (B) were highly correlated with the production yield of hydrogen and the system output power.…”

Kinetic modeling on quality parameters of raw Kelulut honey during dehydration process

“…It is a conventional approach of food preservation method by reducing moisture in foods up to a threshold that retards growth of spoilage microbes (Krokida, Karathanos, Maroulis, & Marinos‐Kouris, ). Recently, many drying methods were developed and applied on honey which includes low‐temperature vacuum drying with induced nucleation (Ramli et al, ), microwave and infrared heat drying (Hebbar, Nandini, & Lakshmi, ), spray‐drying (Cuevas‐Glory, Pino, Sosa‐Moguel, Sauri‐Duch, & Bringas‐Lantigua, ), and freeze‐drying (Jedlińska, Samborska, & Witrowa, ). However, these approaches require use of high‐cost equipment which might not be feasible for small‐scale meliponiculture farmers.…”
