Three CBD oil varieties to discern

You should know that there are three types of CBD oils that differ by their contents: full spectrum, broad spectrum and isolate. Full Spectrum means that all-natural compounds of the hemp plant are present in the extract, including THC, and work in synergy creating the entourage effect. The legal requirement for THC content is up to 0.3 percent in the US and EU. This low quantity of THC doesn’t cause a high. The purest form of CBD oil is CBD Isolate because it contains only CBD. In this case the CBD is filtered out and other chemical compounds are completely removed. In the middle ground between the full-spectrum and the isolate, there is Broad Spectrum CBD oil. It has all the cannabinoids and the other chemical compounds except THC, which is removed after the extraction process.

How to get these three different CBD oils?

Ethanol extraction

is a very good choice for those who want to produce a full-spectrum extract. All the natural occurring components of the hemp plant stay intact after the extraction process because the oil is minimally filtered. After extracting, refining, and distilling the oil, CBD isolate and broad-spectrum CBD oil are made by chromatography. This technique is used to separate THC from the rest (broad-spectrum) or to isolate cannabinoids (CBD isolate) via molecular structure. In a column, the extract is dissolved in a fluid that is passed through a filter (sand). Molecules of the different compounds travel at different speeds through this filter – small molecules travel faster than big ones; this principle can be used to separate different compounds or to capture a specific one – THC for example. To obtain a 99 percent purified CBD for CBD isolate, this process must be repeated several times. After the purification process, crystallization can take place as CBD crystals are the most popular form of CBD isolate nowadays. Click here to discover more about CBD oil.

Formulation considerations for chewable tablets

Over-the-counter vitamins for kids come in chewable form basically to be easily swallowed. Chewing exposes tablets to saliva, which breaks them down directly in the mouth where dissolution occurs. This increases the absorption rate compared to conventional tablets which are mainly absorbed after disintegration and dissolution. Different types of sweeteners and flavours are added to the formulation to make these vitamin tablets easy to chew and eat. Unfortunately, this could be a two-edged sword because adding sweeteners such as mannitol, sorbitol, lactose, or fructose means adding sugars and this can also lead to health problems. To match the flavour, artificial or natural-derived colouring agents are used to create aesthetic appeal. Of course, factors as stability, accuracy, flow, lubrification, compressibility should not be lost sight of during the tablet manufacturing process. Be careful though, looking like candy, chewable vitamins can tempt children to consume more than the recommended dose.

Producing chewable tablets on a tablet press

FDA recommends that hardness for chewable tablets be kept low, for example <12 kp, because they should be easily crushed by chewing. Manufacturing of chewable tablets can be carried out by direct compression using a tablet press. Tablet presses consist of punches (lower and upper) and dies and come in different level of speed and automation. Dies are filled with tablet formulation and the upper and lower punches are pressed together within the dies to form tablets. Dies and punches are called tablet tools because they define the size and shape of your finished tablet. Kids tablets are often shaped as animals to lure children to eat them more easily. See below video on forming tablets on a tablet press.

How does ethanol extraction work?

During ethanol extraction, plant material is soaked in ethanol for a period to separate plant’s cannabinoids and other compounds from the plant matter. Soaking time will depend on the ethanol temperature. As an alcohol, ethanol has a “polarity problemâ€. It can dissolve cannabinoids, but also unwanted compounds as fats, waxes, chlorophylls, and other water-soluble compounds. These elements should not be included in the final product and therefore must be removed through a process called winterization.

The advantages of cryogenic ethanol extraction

By bringing ethanol to a sub-zero temperature (-40°C), the solvent will not extract waxes, fats, chlorophyll. Without the unwanted compounds being extracted, winterization step can be skipped in the process. The cryogenic ethanol extraction method reduces the extraction process from several days to just a few hours. CryoEXS designed by Devex, is a cost and time efficient solution that speeds up the extraction process by using cold ethanol. It allows to skip several steps, that must be followed during other extraction methods. Cryogenic ethanol makes the extraction process easily scalable because the production capacity can be doubled. With cold ethanol, there is also no need for a pressurized system. This reduces explosion risk, making cold ethanol a safe way to extract CBD oil.

More details about desiccants

Desiccants play a major role in the pharmaceutical sector, with silica gel canisters being the most popular. In the pharmaceutical as well as nutraceutical industries, Desiccants are generally used in the packaging of herbal, diagnostic, veterinary, dental and nutritional medicines. They are defined as small High-Density Polyethylene or HDPE containers having adsorbents like 1) Clay for moisture adsorption 2) Silica Gel for moisture control 3) Molecular Sieves for water vapour and impurities adsorption 4) Activated Carbon for good odour and finally Silica Gel in combination with Carbon to control bad odour and excess humidity. The desiccant canisters are placed in the medicine bottles at a very high speed. A specialty of the Desiccant Canister available in the market nowadays is that they are all food grade.

Importance of inserting desiccants

When being packed in bottles, for the pharma industry, desiccants are usually inserted in the form of canisters or medicinal capsules into the packaging lines to ensure that the medicines are not affected by moisture, mold, rust, mildew and micro-organisms. Moisture Control is very important for pharmaceutical products as the presence of dampness can not only spoil the medicines, but in many cases bring about irreversible physical and chemical changes. Thus more and more pharmaceutical companies are turning to desiccants to protect products from excess humidity. When inserting with pouches, the inserting machine cuts desiccant packets from a roll and inserts them at a speed of up to 120 bottles per minute. The desiccant inserting machine is another machine which can fill up 150 bottles with desiccant canisters every minute.

Dispelling the myths around cbd products

Due to the uncertainties around CBD production and use, all eyes are on cannabis products and their effects. It is under heavy scrutiny and hence one bad product can easily taint public opinion and serve as misinformation about the industry at large. Thus, CBD oil manufacturers must actively work to distinguish themselves as experts in safety and quality. Most producers of CBD oil infused products such as gummies, encounter their fair share of difficulties, transferring their product to widespread application. This is because incorporating cannabis within vaping oils, lotions, food, and other products for public usage is an intricate process. Thus using a high-pressure homogenizer is essential and can alleviate many of the difficulties associated with the production of medical and commercial cannabis products. It not only creates better looking and better tasting products, but also increases the bioavailability of the CBD compound by maximizing surface area to allow increased dissolution and absorption. Thus facilitating the absorption of more active ingredient so well that manufacturers can use less of it, reducing costs and shortening production times.

Extracting CBD oil from hemp

Another myth people have is that CBD and Cannabis are the same thing. This is not true as CBD is one of many chemicals found in the resin of the cannabis or “marijuana†plant. (for instance, THC, is another.) Traditionally, the most common extraction methods used in the creation of cannabis crude oil have been CO2 extraction, light hydrocarbon extraction, and warm ethanol extraction. However, for crude CBD oil, cold-ethanol extraction process offers a highly time-efficient and effective solution. This is because it provides the benefit of bypassing several steps in the hemp processing facilities, reducing the extraction process of crude CBD oil down from several days to just a few hours. After this process the crude CBD oil is then distilled or put through various other processes depending on their application and the respective country legislations.

Skin pack. Why is it so good?

Even though skin packaging is known for a few years now, food producers were hesitant to use it. The reason is that consumers are used to seeing fresh meats, poultry, and seafood presented with a top seal over a deeper tray because that is how it has always been. With skin the outer packaging looks almost invisible — the top film is pulled onto the product tightly, eliminating nearly all package atmosphere. This is a great advantage of skin packaging as it guarantees maximum shelf-life while the product shape is well maintained without any liquid leakage.

Recent developments in skin packaging

Luckily, this situation is now changing toward greater acceptance due to newer films that can accommodate products of different shapes, high protrusions, and sharp edges. And with the ability to skin pack with paperboard, there is an expanded range of applications and options for this type of packaging. Production companies do not stop on the achieved success and keep developing more environmentally friendly options for both films and trays.

Inspection of unpeeled and peeled tomatoes

Nowadays technologies allow you to inspect several types of tomatoes on one machine. For example, unpeeled and peeled tomatoes can be inspected on one machine with the speed up to 100 tons per hour on unpeeled tomatoes. It is an important step in production as it sorts out both foreign objects (from mice and frogs to pieces of wood and stones) and tomatoes that are not good enough for processing.

The processing of tomatoes as well as seeds from the tomato will involve various steps as well as various pieces of equipment and machinery.

Inspection for processed tomatoes

If a company works with diced, crushed tomatoes or tomato pulp, it also needs an inspection machine. Rotten, yellow, or green pieces, as well as foreign objects, should not end up in the customer´s jar. This is especially important for ketchup processing as well as making tomato sauce. The speed of the equipment, in this case, will be up to 18 tons per hour. Optical inspection successfully detects and takes out everything that does not belong to the product.

Stevia plant and how it is used

Stevia comes from the leaves of the stevia rebaudiana Bertoni plant. It has been a source of high-intensity sweetness for centuries, and its leaves and crude extracts have been sold as dietary supplements. Stevia plants usually grow on farms in Asia, South America, or other tropical/sub-tropical climates. Stevia production process contains several steps. First stevia leaves are harvested and dried. That helps to extract the plant’s intense sweetness. Purified extracts of the sweet substances found in the stevia leaf are called steviol glycosides. Steviol glycosides are extracted from the leaves of the stevia plant. In the end, the extract is purified in order to remove some of the bitter attributes found in the crude extract.

How to produce something so sweet?

A manufacturer can decide to package the stevia leaf extract in any number of forms depending on who will be using it. Thanks to the fact that stevia leaf extract is very sweet (200-350 times stronger than sugar), much less is needed to produce the same level of sweetness. However it also makes it difficult to use, that’s why some manufacturers choose to combine it with other ingredients to even out the sweetness. For example, a sugar substitute may contain stevia leaf extract along with other ingredients, like inulin or erythritol to produce a stevia-based sweetener that can be used the same way as sugar.

From farm to the fryer

The availability of raw inputs combined with a high local and global demand provides food processing companies and local farmers with many growth opportunities. A regular potato chip plant makes thousands of chips every hour. The potatoes are washed and de-stoned to ensure they are clean and prevent damage to the peeling, slicing, or dicing units. In the peeling stage, batch type, abrasive peeling takes place. The potatoes then move along a belt to a slicing machine that slices them quickly using a razor-sharp blade. Ripple potato chips are cut by a serrated knife. It is then transported into a blancher to reduce the sugar content from the potato slices to prevent quick dark coloring and maintain product quality. These potato slices are then put into a vat of boiling vegetable oil with special deep fryer equipment. As the potato chips cook, the water inside them turns to steam. After this, they are collected, drained, salted, and then ready to be packaged.

Producing the perfect bite

The fried snack market around the world is constantly growing. The main factors facilitating this growth include lifestyle changes, increased urbanization levels, and simply because the population has access to many more snacks than in previous years. This makes optimal production and quality control of utmost importance. The transportation of your product through the fryer must be perfectly done. Every piece must have the same frying time and no possibility of staying behind and burning. The industrial fryers for making potato chips are a continuous and fully automated production plant that ensures gentle heat transfer to heat the frying oil so that your chips/crisps are evenly fried. It also prevents the degradation of the oil quality, allowing you the lowest possible oil turnover needed!
