Advances in spray drying of sugar-rich products

Abstract

Recent developments in the spray drying of sugar-rich products such as fruit juices, pulp and honey with and without the application of carriers, e.g., carbohydrate carriers (maltodextrin, gum arabic), prebiotic dietary fibers, proteins and natural carriers have been presented in this paper. The effect of the carrier type, carrier concentration and the spray drying process parameters on the product yield and selected final product properties are analyzed and discussed. Recent studies have proved that prebiotic dietary fibers and proteins may substitute conventional carriers, i.e., refined carbohydrates, providing high product yield and additional nutritional value at lower carrier concentration in the final product.

Dehumidified Air-Assisted Spray-Drying of Cloudy Beetroot Juice at Low Temperature

“…The differences could have been caused by other parameters involved the drying process and the chemical composition of skimmed milk powder. The addition of nutriose (T g : 15 • C) and kleptose to beetroot powder as a carrier resulted in an increase of the T g of beetroot powder to 68.52 • C and 69.22 • C, respectively [20]. Higher values for T g were found in for powders with the addition of carriers.…”

“…The powder produced with maltodextrin (JMD 130) showed a higher T g of 70.06 • C. The T g of maltodextrin is depended on the dextrose equivalent (DE), which is related to the decrease in the molecular weight that decreases the T g [19]. According to Sobulska and Zbiciński (2020), maltodextrin with a DE from 36 to 5 is characterized by a T g in a range from 100 to 188 • C [20]. The T g of skimmed milk powder at 58 • C (water activity: 0.1) and 34 • C (water activity: 0.2) was obtained by Jouppila and Roos (1994) [21].…”

“…Research on various carriers used in spraydrying has been undertaken, including maltodextrin, gum arabic, and inulin. Sobulska and Zbiciński (2020) investigated honey and fruit juice powders, Flores-Mancha (2020) studied beetroot powder, and Goula and Adamopoulos (2008) examined tomato pulp [18,20,27]. The T g of beetroot powder produced with different carriers explains the good quality of the powders obtained at 55 and 80 • C outlet temperatures.…”

How Do the Different Types of Carrier and Drying Techniques Affect the Changes in Physico-Chemical Properties of Powders from Chokeberry Pomace Extracts?

“…One technique that enables the use of high drying temperatures while excluding the effects of oxygen on the dried matrix is vacuum drying [14]. However, the thermolability of polyphenols, especially anthocyanins, to thermal processes, as well as the different yields for obtaining powders depending on the raw material composition, induce the necessity of using a carrier additive in the drying process [15]. Substances of carbohydrate origin, such as maltodextrin, are widely used for this purpose and have proven protective properties, allowing for an increased retention of anthocyanins at high drying temperatures compared with other carriers [14].…”

Influence of phospholipid saturation on the physicochemical characteristics of curcumin/vitamin D 3 co‐loaded proliposomes obtained by the micronized sucrose coating process

“…Although the hygroscopicity of the PLs tended to increase with higher LS40 incorporation, the results obtained for the samples did not differ significantly considering the standard deviations, and all of them exhibited low values for this parameter. Highly hygroscopic ingredients may be considerably harmful to the final product, as they directly affect some manufacturing steps, such as collection, transportation and handling (Sobulska & Zbicinski, 2021). The similarity of the values found for the samples is probably due to the similar number of hydrophilic groups appearing in each structure.…”
