Make Citrus Powder
The process for making powdered fruit juice comprising evaporating a fruit juice concentrate of about to solids content to at least about 96% solids content by forming the concentrate into a film Cited by: 5. I'm interested in using dried lime juice powder in place of citric acid powder for things like dusting fruit leather to make sour fruit candy. Can't you just leave some juice out in a shallow pan in the sun and then powder the result in the b.

This invention relates to processes for the dehydration of fruit juices. This high water content places a heavy burden on the packaging, handling, storing and shipping of such juices and has stimulated the development of many processes for the partial or complete dehydration of such juices. Many difficulties have been encountered in fuit processes, especially those processes yielding dry, solid products, and heretofore there has been developed no practical process for the production of powdered juices that can be readily reconstituted by the addition of water to yield a product closely resembling fresh juice in flavor and appearance.
The major difficulties encountered in prior processes, mak addition to high'cost are 1 loss of volatile flavoring constituents during the process of ,con.
An object of this invention is to provide economical processes for the substantially complete dehydration of fruit juices. Another object is to provide processes for producing powdered fruit juices wherein the product suffers negligible heat damage. Another object is to provide processes for the production of powdered fruit juices that may be quickly reconstituted by the addition of water to yield a product having substantially the flavor and appearance of fresh juice.
In the preferred procedure the fresh juice is stripped of volatile essence in a flash evaporator and the essence is further concentrated to perhaps or ZOO-fold. This must be done without objectionable heat damage and is suitably effected in a vacuum flash evaporator. The concentrate thus produced is the powderrd starting material for the present invention. In general according to the invention, the fruit juice concentrate is preferably passed through a preheater into a vacuum down-flow film-type evaporator in a film of the order of 1 mm.
The film is then cooled to about ordinary room temperature toproduce a hard, brittle solid that is readily ground to a powder.
The powdered product, when packaged in a moistureproof container, particularly if an inpackage desiccant is used, may be stored at ordinary temperatures without caking. It readily dissolves in water to yield a product closely resembling fresh juice in flavor and appearance.
If preferred the essence can be returned to the finished powder by first absorbing it in sorbitol, sugar or the like and then powdering. An evaporator that has been found satisfactory for the final concentration step has a vertical tube, jacketed for heating fluid, down the inside of which flows the sirup being concentrated. Rotating blades within the tube keep the sirup in a thin film on the heated wall. An overhead outlet leads to a condenser and vacuum pump while a bottom outlet serves for removal of the product.
The preheated concentrated juice is fed in above the heated zone at such a rate that the final product has the desired moisture content. The heating fluid is supplied at as high temperature as can be tolerated without excessive heat damage to the product. It has been found that steam at about 25 pounds per jake inch gauge is suitable for most juices. The vacuum in the evaporator should be high enough to produce rapid evaporation without excessive temperatures, though very high vacuumreduces the capacity of the unit because of the increased vapor volume and requires larger condensers, colder cooling fluid and yo vacuum pumps.
A practical compromise suitable for most juices is to use a vacuum of about 20 to 26 powxered of mercury. It is necessary, in selecting optimum values for the several process variables to first determine the moisture content desired in the final product. If the product is chilled below room temperature before being ground, somewhat higher moisture content can be tolerated.
Having determined the final moisture content to be reached the three variables, feed rate, temperature and vacuum, governing the operation of the film-type evaporator are readily how to increase work productivity to the optimum operating condition where maximum throughput with minimum heat how to get a aim is obtained.
The falling film type vacuum evaporator with rotating blades is the only type that has been found to give a satisfactory product. Its great advantage lies in the very rapid concentration it eifects, so that heat damage is minimized. The actual contact time in such an evaporator varies from a few seconds to, at most, a very few minutes, depending on the dimensions of the apparatus, feed rate and the viscosity of material being processed.
A suitable evaporator is that described in U. Patent 2, The following examples illustrate the practice of specific embodiments of the invention. The stripped juice was depectinized by use of commercial pectinase, after which the pectinase was inactivated by heating the juice to F.
To each g. Thismixture was then pumped'through a tubular preheater which raised its temperature to F. At a feed rate of pounds per hour the contact time was less how to use extraction tool blackheads 1 minute and the product emerged as a molten sirup at F.
Fruif product wasthen a hard brittle solid which was ground in a hammer mill to pass a mesh screen. The coarse powder thus obtained readily dissolved in water-to make a reconstituted kake closely resembling fresh juice in appearance and taste. When packaged in moisture-proof packages containing a'paper envelope containing calcium oxide, the powder could be stored for at least several months at temperatures up to F.
The product could be reconstituted or packaged dry as described in Example-I. When reconstituted either, immediately or after several months storage, it yielded a juice closely resembling fresh apple juice. It has been observed that about l-mesh size is the optimum for the powdered product. Coarser lumps are slow to dissolve when the juice is reconstituted. Finer powder has a greater tendency to cake in storage and also tends to form large, sticky agglomerates during reconstitution unless the powder is added free download gbwhatsapp latest version the water slow 1y and'with vigorous stirring.
Of course, other types powderred grinders or crushers may be used to reduce the product to a powder; the only precaution required is that excessive heating be avoided, otherwise the powder will become sticky and cannot how to make powdered fruit juice screened or handled satisfactorily. Powcered general a temperature.
While what is the countries of north america examples above are limited to grape and apple juices, the process is applicable to any fruit juice.
It is particularly valuable for processing the juice of grapes, apples, blackberries, raspberries and cherries.
The addition of sucrose or other sugar sirups, fruit acids or essences to hwo concentrates is entirely optional and does not affect the operability of the process, though in most cases they improve the flavor of the reconstituted juice.

Jul 24, · Here is the step-by-step procedure: Start with cleaning and washing the fruits you want to juice up. Also, peel and slice them up (exception: grapes) before taking the sap out. Now, it is time to make the juice. There is a wide variety of juicers available . Make Citrus Powder Step 1: Pick Your Citrus. I wanted to try a bunch of different kinds of citrus, including several varieties of oranges, Step 2: Prep Work. Remove stickers/labels and thoroughly wash all your citrus. Line as many baking pans with parchment Step 3: Get Low. Turn your oven on.
Today we are going to make dehydrated fruit powder. Why would anyone want to make their own fruit powder? Here are some suggestions for what you can do with it. You see, you can let your creativity go wild with fruit powder. Be sure to let me know how you use it in the comments section. Now turn your blender on Low, then slowly work your way up to High. Let it run until you end up with a fine powder.
Many dehydrated fruits are somewhat sticky, due to the sugar content. Make sure your dried fruit is dried very well. Again, with the word. That being said, even when you are using a well-dried batch of fruit, the stickiness is simply innate in the fruit.
No worries, friend! We got you covered here. Add it anytime you are making fresh lemonade, and let it sit for about 10 minutes before serving. My family makes fresh fruit drinks out of just fruit, We do strawberry, pineapple, apple, peach, pear, etc. So with the dehydrated fruit, it would be the dehydrated fruit, just add water and sugar to taste and serve to drink. Hi Kristine! Since it is dried fruit, it will last months in the pantry, assuming it was dehydrated well and kept in an airtight container.
I have a FoodSaver vacuum sealer that has an attachment separate purchase that fits over the lid of a canning jar without the ring. I push the button and it vacuum seals the jar. This is how I store all of my dried foods, nuts, dry beans, etc.. It is much more practical than buying the bags or rolls to seal all of it, plus it is a more secure seal.
The bags can easily get a hole and then they lose their seal. Also, delicate items, such as beet chips, break from the pressure of the vacuum process. They remain in perfect condition in the jars. I use only wide mouth jars because I can get my hand inside to pull out food or to wash them. One word of caution from my own experience, boo hoo , do not try to vacuum seal extremely fine, light weight powders and flours, such as arrowroot, tapioca, corn starch, etc.
It will plug up the insides of the machine. My last machine would still seal a jar but it would not shut off so I did not know when all of the air was out. After buying a new one, my DH took apart the old one, further than they really want customers to go, and it was all white inside. No amount of cleaning would get the machine back to being able to shut off. To test if a powdery product will work in the sealer, fill the jar, leaving at least 2 inches of space at the top of the jar.
Be sure that the jar rim and the rubber seal on the lid are totally free from even the smallest particles. Put the attachment over the lid and push it down into place. Turn on the sealer and watch to see if there is any movement in the contents such as: 1.
Contents are slowly climbing toward the lid. Visible channels are forming with product moving through them causing a flurry of activity in the empty space.
Any ideas of what else I can add to the mix!? Melissa, what a great idea!!! You can add grass-fed powdered gelatin for a high-quality protein that has an amazing healing effect on the body. About 1 Tablespoon per smoothie. It would be great for your brother!
Other ideas would be finely shredded coconut, cocoa, cinnamon if he likes those types of flavors. You linked to the best gelatin from what I have read from other sites but I would suggest linking to a single can vs 2 cans if you get a commission since someone just trying it out would probably just by 1 at first not knowing what to expect.
You can also make a simple desert with dried fruit like peaches and cherries lets say, or whatever you like really , honey, some lime juice, and a little lime zest.
Then take some whipped creme cheese or ricotta cheese and put the mixture on top of the cheese add some vanilla and maybe a little sugar to the cheese, to taste. Spoon onto shortbread cookies or just enjoy on it's own. Very easy, very delicious.
Fruit powder should definitely work! When using the dehydrator, how are we confident only water is dehydrated and all fruit nutrients still remain?
If it loss some nutrients normally, are there any affordable methods to keep nutrients as much as possible? Dehydrating at a low heat is a great way to retain as much nutrition as possible in an affordable manner. Yes, you can definitely dehydrate vegetables! Check out the link in my sidebar for Dehydrator Recipes — I hope that gives you a good start!
I dehydrate vegetables all the time. I use the big leaves stems removed from cruciferous plants that we do not normally eat for meals and dry them until crispy, crush them with my hands and place them in a jumbo zip bag.
When I have a bag full, I grind them to powder in my Vita-Mix. This can be used for green drink mix, added to smoothies, vegetable drinks, soups or use your imagination. What do I do with the stems, you ask? Juice them and freeze the juice in ice cube trays, pop them out and store in an air-tight bag in the freezer for use in soups, smoothies, drinks, etc. I used to dry raw ones at degrees to retain their raw properties but I have heard and read from some sources that eating them raw can cause problems with your thyroid so, from now on, I will dry them from raw at degrees or steam them and then dry them at degrees.
I do dry beet and sweet potato leaves raw at degrees. I dry steamed green beans at degrees. They are crunchy and delicious dried and are a great addition to soup or stew, even stir fry, when dehydrated. I love to cook and slip-skin my beets, then slice them thin and dehydrate them. I also cube and dry cooked beets, turnips, rutabaga, butternut squash and sweet potatoes for later use. Since they are already cooked, I dry them at degrees.
I am also experimenting with making chips from some of these, too. Summer squash and zucchini are great to dry from raw. If I want to make chips, I slice them thin and dry them at degrees.
If I want to dry chunks that I will use in cooking, I dry them at degrees. Right now I am drying raw tomato wedges with skin on at degrees. I stand them up, skin side down on parchment paper-lined trays and sprinkle Himalayan salt over them. When they get dry, I plan to grind them into powder to use for soups and sauces or whatever. I also make yogurt in my dehydrator. Will there be loss of nutrients if sun-dried? I have never tried sun drying, so I am not sure about the loss of nutrients.
However, if you are wanting to, I think sun drying would be something to look into! Cut into pieces and put on a parchment paper, not touching, in a cookie sheet. Still, the drying is worth it because more fits in the freezer than if I stored fresh fruit. Vitamin C is not heat stable, so any method involving heat could reduce that. And freezing except for very quick freezing done by commercial frozen food makers may degrade some of the protein. I currently infuse beet root powder in olive oil, strain it off when it is done and use it to make lip balm.
Can I use other fruit or Veggie powders using this same method? I guess you are looking for the crispiest texture to change them in powder? I hope that helps!! I want to make a powdered drink powder to take with me when traveling. This may be a stupid question, but will this dissolve in water? So the little fruit particles will probably swell. How do you make smoothies with these powders? My daughter is leaving for college in a few months and I want to make up smoothie packets for her that she can add her wet ingredients to to make her smoothies at school.
Mix some fruit powder and also tell her to add her favorite milk and some ice, if she can. I bet that would be yummy. You can add cacao powder too. I might have to try this out myself. Your email address will not be published.
