Sok i Smoothie Homogenization koristeći Power Ultrasonics

Juices, smoothies and beverages require reliable and efficient homogenization to provide a desirable flavour and texture as well as long-term stability. Ultrasonic high-shear homogenizers are widely used in the food and beverage industry to produce juices, drinks, purees and sauces of superior quality. As a non-thermal treatment, ultrasonic high-shear homogenization prevents vitamins and bioactive compounds from thermal degradation, whilst delivering outstanding stability and smoothness.

Ultrasonic High-Shear Homogenization of Juices, Smoothies and Beverages

Ultrasonic high-shear homogenization improves flavour, texture, nutritional profile, and smoothness.Ultrasonically improved stabilityavoiding phase separation and sedimentation: Fruit and vegetable pulp is broken down into small particles achieving high stability, avoiding sedimentation and giving a smooth texture.
Ultrasonic modification of juice viscosity and texture: Fruits and vegetables such as apples, carrots, oranges, grapefruits, lemons, and tomatoes are rich in pectins. Pectins are polysaccharides that function as natural stabilizer. Ultrasonic homogenizers extract the pectins from the cell matrix and release it into the juice, thereby increasing viscosity and stability. Ultrasonic homogenizers are therefore great in making use of natural stabilizers such as pectins.
Improved phytonutrient profile by ultrasonic extraction: Ultrasonic homogenizers break cell matrices and promote the release of entrapped molecules such as vitamins, antioxidants, polyphenols and flavonoids into the juice product. The phytonutrients become thereby more bioavailable and bioaccessible when consumed.
Intensified flavour profile due to sonication: Ultrasonic high-shear homogenizers not only release pectins, but also flavour molecules, essential oils, natural sugars and phyto-nutrients. (For ultrasonically improved nutrient profile, see case study below). Ultrasonic extraction releases bioactive molecules such as flavour compounds and vitamins from the cell matrix and makes them thereby available for the consumer’s taste buds.
Intensified Colour Profile due to Sonication: Plant pigments are also contained in the plant’s cell matrix. Ultrasonic homogenizers release plant pigments such as carotenoids, chlorophyll, betalanins and anthocyanins and reduce them in particle size. The reduced pigment size scatter light better than larger particles and obtain thereby an intensified color of juice, puree or sauce.

Ultrasonic Juice HomogenizationManifold Benefits

Ultrasonic high-shear homogenizers are reliable and efficient for mixing beverages such as fruit juices, nectars, vegetable juices, smoothies, fruit-infused lemonades, flavoured milk drinks, protein shakes, infused drinks and more.
In juice extraction and pressing, ultrasonication can increase the yield of juice. For instance, ultrasonic treatment increased grape juice yield by up to 3.4 %, while shortening the treatment time threefold. Ultrasonication combines with enzymatic treatment also increased juice yield up to 2 % and shortened treatment time over fourfold when compared with traditional enzymatic treatment. The successive application of ultrasound and enzymatic treatment increased juice yield up to 7.3 %. Similarly, in pineapple juice ultrasonication alone increased the extraction yield by 10.8 % for juice from pineapple mash. The ultrasonic treatment also enhanced the content of sugars, total acids, phenolics, and vitamin C. (cf. Baslar et al. 2015)
Manufacturing beverages such as juices, juice-infuced lemonades and other drinks requires reliable homogenization and emulsification for stability, enhanced flavour and texture, appealing optical apprearance, and improved functionalities. For instance, ultrasonic homogenization provides exceptional stability, prevents phase separation and improves flavour and texture of juices, smoothies, as well as milk- and protein-based drinks. Furthermore ultrasonic high-shear homogenizers easily emulsify various ingredients to produce clear emulsions. A common application of ultrasonic emulsification is the preparation of cannabis-infused waters and beverages. Clear water beverages and other drinks can be ultrasonically infused with stable cannabinoids (e.g., CBD, CBG, THC). In order to obtain clear emulsions with a high bioavailability of the active compounds, the bioactive compounds must be emulsified at nano-size. Ultrasonic emulsification is the superior technique for producing nano-emulsions with clear appearance, exceptional stability, bioavailability, and functionalities. Therefore, ultrasonic nano-emulsification is widely applied in the manufacturing of pharmaceuticals and supplements (e.g. CBD tinctures etc.)
At the same time, ultrasonic homogenizers extract flavour molecules, bioactive compounds and phyto-nutrients making them more bioavaialable and bioaccessible. But ultrasonic homogenizers also dissolve sugars, syrups or sweeteners and disperse and hydrate gums, starches and other additives into long-term stable suspensions. A single Hielscher ultrasonic unit provides your juice and beverage manufacturing with the fulfilment of the various tasks of homogenization, nano-emulsification, extraction, dispersing, dissolving, hydration and blending.

Ultrasonication improves the particle size, structure and smoothness of fruit juices and nectars such as apple juice and orange juice.

Case Study: Improved Nutrient Profile in Sonicated Orange Juice

Ultrasonic high-shear homogenization is a non-thermal method of food preservation and processing that has the advantage of improving stabilization and inactivating microorganisms in fruit juices without causing the common undesired side-effects associated with conventional heat treatments. Guerrouj et al. (2016) investigated the effects of ultrasonication on total phenolic and flavonoid content as well as on carotenoids and ascorbic acid (vitamin C) in orange juice using a Hielscher Ultrasonics UP200S homogenizer. They found a significant increase in the total phenolic content in the sonicated orange juice samples when compared to a control (see table below). This increase was from 42.74 up to 69.45mg GAE/100 ml for an ultrasonic treatment of 30 min. These results show a significant enhancement on phenolic compounds within sonication treatment.
The results on DPPH free radical scavenging activity of orange juice are also represented in the table below. Sonicated samples showed significant increase in the percent DPPH inhibition compared to control indicating a higher level of antioxidants. The per- cent inhibition of DPPH was 37.48%, 35.70%, 34.70% and 35.21% in 1, 10, 20 and 30 min sonicated samples, respectively compared to control samples (21.67%). These findings are congruent with the results found in sonicated kasturi lime juice (Bhat et al., 2011). These results indicate that sonication treatment enhance the extractability of antioxidant compounds.
The researchers conclude that ultrasonic treatment of orange juice resulted in a general enhancement in bioactive compounds such as total phenolics, flavonoids, carotenoids, anthocyanins and ascorbic acid with significant reductions in the microbial counts.

Juice, Juice from Concentrate, and Nectar

Juice is a drink made from the extraction or pressing of the natural liquid contained in fruit and vegetables. It can also refer to liquids that are flavoured with concentrate. Juice is commonly consumed as a beverage, but can be also used as an ingredient or flavouring component in foods or other beverages, as for smoothies.
Juice is differentiated into 100% juice, juice from concentrate, and nectar. 100% juice is fruit juice made from 100% from natural fruits and vegetables without added colourings, preservatives or sugars. However, fruit juice can be prepared in different ways, ie. from fresh unconcentrated juice or made from juice concentrate. For the former one, the fruits are pressed and stored or bottled direct after fruit harvest. For the latter juice variant “made from concentrate”, the pressed juice is concentrated by removing water from the freshly pressed juice under a vacuum treatment. Thereby, a syrup-like concentrate is obtained, that has reduced volume, which is favourable for transporting the juice product. After shipping the juice concentrate to its final destination, it is turned into fruit juice by adding water.
The term nectar refers to the juice from fruits that contain too much fruit acidity or fruit pulp to be consumed as 100% juice. Common examples for nectar-producing fruits are bananas, mangos, apricots, peaches or pears. The juice or, which is technically a purée, is diluted with water and might have sugar added give it a drinkable consistence and pleasant flavour. The fruit juice content in nectar varies between 25 and 99 % depending on the fruit content and manufacturer’s recipe. Whilst nectar might contain added sugars, it does not contain any colourings or preservatives.
Other beverage forms that containing juices are juice-flavoured lemonades and milks, smoothies and fortified juice products. Juices can consist in the extract from a single fruit or vegetable or be combined from two or more fruit and vegetable sources. Most popular fruit juices are made from oranges, apples, cranberries or grapes. Other popular fruit-based beverages are made from pineapple, passion fruit, grapefruit, mango, banana, cherry and kiwi.
Commercial vegetable juices are commonly made from varying combinations of carrots, beets, celery, pumpkin, and tomatoes. The latter two, although not technically vegetables, are commonly used to increase palatability. Other popular items in vegetable juices are parsley, dandelion greens, kale, celery, fennel, broccoli, and cucumbers. Lemon, garlic, ginger, tumeric and other spices are added for health benefits and to create interesting flavour profiles.
Another application of ultrasonication in beverage production is the intensified and improved fermentation of kombuchas and kombucha-like juices. Click here to read more about ultrasonically improved kombucha fermentation!
