“…HC processes found convenient application also with unconventional, land-neutral plant materials, such as microalgae. High HC-driven extraction yield of lipids (25.9-99%) from microalgae (Nannochloropsis salina) was obtained, due to the effective cell disruption, showing decreased energy consumption and straightforward scalability (Lee & Han, 2015), as well as it emerged as the fastest process of lipid extraction in comparison to conventional methods (Setyawan, Mulyono, & Budiman, 2018). HC-based edible oil (including algae's oil) extraction and refining technologies have already reached the industrial level (-Degumming | Arisdyne,‖ 2019; -Edible oil refining | Cavitation Technologies, Inc.,‖ 2019).…”

Improving the food system sustainability and security is becoming an urgent global challenge. In this regard, one of the most effective routes is the shift of the human diet toward healthier and more sustainable consumption, involving in particular the prevalence of plant-based raw food materials. Controlled hydrodynamic cavitation (HC) technologies could help considerably in this transition. HC techniques are gaining increased scientific interest, and are quickly spreading across a wide range of technical fields, recently showing surprising performances with biological raw materials related to the food, agricultural and forestry sectors and resources. HC processes enjoy recognized advantages in the acceleration of the processing steps of plant-based food, the extraction of valuable bioactive compounds, the reduction and the valorization of waste streams, as well as the superior efficiency in resource use, energy consumption, process yield, and exergy balance than competing processes. Thus, HC is very promising candidate to help addressing the water-energy-food nexus, and, ultimately, sustainability. Findings obtained from direct experimental trials and recent literature concerning the applications of HC to food processing, provide a strong basis for novel investigation aimed at standardization, starting from the identification of the most suitable devices and the optimal processing parameters, eventually oriented to further spreading of HC applications.

“…The volumetric mass transfer coefficients of HCE was 7.373/s, while those of agitation were 0.534 and 0.121/s at 1000 rpm and 260 rpm stirring speeds, respectively. According to the thermodynamic parameters, ∆H • (20.72 kJ/mol), ∆S • (58.05 J/mol/K) and ∆G (1.969-3.013 kJ/mol at 34-50 • C), the process of lipid extraction was considered to be endothermic, non-spontaneous and irreversible, indicating that more energy was consumed compared to the extraction from other oil plant sources [8]. In a similar study, a closed-type 0.9 L HCR with an orifice plate (0.5 mm × 13 holes in radial pattern) was fabricated for the lipid extraction from wet microalgae Nannochloropsis salina with hexane (1:0.8 v/v).…”

Hydrodynamic cavitation (HC) is a green technology that has been successfully used to intensify a number of process. The cavitation phenomenon is responsible for many effects, including improvements in mass transfer rates and effective cell-wall rupture, leading to matrix disintegration. HC is a promising strategy for extraction processes and provides the fast and efficient recovery of valuable compounds from plants and biomass with high quality. It is a simple method with high energy efficiency that shows great potential for large-scale operations. This review presents a general discussion of the mechanisms of HC, its advantages, different reactor configurations, its applications in the extraction of bioactive compounds from plants, lipids from algal biomass and delignification of lignocellulosic biomass, and a case study in which the HC extraction of basil leftovers is compared with that of other extraction methods.

“…Microalgae are single-cell organisms, which are active in photosynthesis producing carbohydrates, lipids, and proteins [19]. They have considerable advantages compared to oil crops as follows: (i) higher growth rate [20], (ii) less cultivation area requirement [21], (iii) higher lipid content [22], (iv) higher ability of carbon capture and storage [23], and (v) more adaptive to low-quality medium (even waste water) [23]. In addition, biodiesel resulting from microalgae has similar properties to diesel fuel [24].…”

Microalgae have been considered as a potential candidate for biodiesel feedstock. Single-stage simultaneous extraction–transesterification process is proposed for simpler and more effective biodiesel conversion. In this study, the experiment of biodiesel production from microalgae Spirulina sp. was performed in a batch-stirred reactor using palm oil as a co-solvent of methanol and catalyzed by potassium hydroxide at a percentage of 1 wt% (w/w of palm oil). The effects of methanol–palm oil molar ratio, palm oil–microalgae weight ratio, and temperature on biodiesel yield were investigated. The results showed that the best biodiesel yield was 85.28% (99.01% of partial biodiesel yield from palm oil and 16.69% of partial biodiesel yield from dry microalgae), obtained at a methanol–palm oil molar ratio of 10:1, a palm oil–microalgae weight ratio of 5:1, and at a temperature of 60°C. Upon comparison, the overall yield increased by 34.59% (37.73% of partial biodiesel yield from palm oil and 13.00% of partial biodiesel yield from dry microalgae) than that of the two-stage (conventional) method. Single-stage simultaneous extraction–transesterification process also reduced the number of unsaturated fatty acid components in biodiesel that will lower the biodiesel quality.
