What are the advantages of freeze drying fresh meat?

The freeze-dried meat is made because the raw materials do not need to be thawed, so the nutrients are basically not lost, which is also its better point. At present, there are relatively few freeze-dried fresh meat in China, as far as I know, there is a small fresh brick freeze-dried that is made of pure fresh meat, its animal raw materials reach 98%, and it also contains 70% high protein, and the nutrition is more balanced. Its freeze-dried products also support customization, and the production date is about 15 days, and the shorter the time, the fresher the ingredients.

The freeze-dried meat made of fresh meat is naturally fresher than the freeze-dried meat made of frozen meat, which is also one of its more prominent advantages. Now there are some domestic brands that are doing this kind of freeze-drying, such as Pat, Lonno, Xianlang, Love Cube, etc., among which Love Cube has launched a small fresh brick freeze-dried, 100% pure fresh meat production, 0 starch, 0 grains, you can smell a faint natural meat fragrance when you open the package, cats love to eat. Double-layer vacuum packaging, can also lock freshness, for cats to eat two words:

Feel relieved! ⌄

Freeze-dried with fresh meat for better freshness. In the past, many domestic brands basically used frozen meat as raw materials, but now the pressure of freeze-drying competition is very high, and some brands are rolled up to make fresh meat. As far as I know, Love Cube is very rolly, and its small fresh brick freeze-dried is made of fresh chicken, which is not only nutritious, but also highly palatable.

My cat loves to eat this, and always loves to follow me when it comes to meals, as long as it wags its tail, I know that it is thinking about the little fresh brick. ⌄

Freeze-dried food is the abbreviation of vacuum freeze-dried food, because it is made through the process of vacuum freeze-drying, so the freeze-dried food maintains the color, aroma, taste and nutrients of fresh raw materials to the greatest extent, as well as the appearance and shape of the raw materials, and has good rehydration, without preservatives can be stored at room temperature for more than 5 years, is a natural and healthy food. There are hundreds of raw materials that can be processed by freeze-drying technology, and in supermarkets, colorful freeze-dried green fruit slices, freeze-dried instant soup, freeze-dried dehydrated seafood, vegetables, etc., can be seen everywhere. And the finished product is light in weight, easy to carry and transport, and is a very convenient food for processing tourism and leisure.

Not only freeze-dried for human consumption, freeze-dried pets also have the advantages of freeze-dried food, so cat freeze-drying is popular abroad, in the past, cats were said to buy what kind of cat food for cats, and now cats have to say what brand of freeze-dried their cats eat, so what brand of freeze-dried is so sought after by everyone? That is Lon Nol freeze drying, what are the advantages of Lon Nuo freeze drying that stands out among the freeze-drying brands? The following is attached to the evaluation table of Lonno's freeze-drying to analyze the advantages of Lonno brand.

Lon No's freeze-dried chicken breast.

It can be seen from the ** of this detection structure that the quality of Lenno is good, rich in crude protein, moderate in crude fat, the total number of bacteria is not high, within the qualified range, the content of moisture is not the lowest in freeze-drying, freeze-drying is made by freeze-drying technology, so the water content is not high, but freeze-dried can be soaked in warm water to feed, cats who do not like to drink water can use this feeding method, restored into meat pieces, easy to digest, good for the stomach.

Lyophilization, as the name suggests, is freeze-drying, the full name of vacuum freeze-drying, is a popular preservation technology in recent decades, common freeze-drying applications: dried fruits, vegetable packets of instant noodles, precious medicinal materials (bird's nest, ginseng, cordyceps), penicillin and the preservation of samples in some scientific research fields. Freeze-drying has the following advantages over ordinary drying preservation:

1) The dried material retains its original chemical composition and physical properties (such as porous structure, colloidal properties, etc.);

Lyophilizers are common in laboratories.

2) Less heat consumption than other drying methods. The disadvantage is that it is more expensive and cannot be widely adopted. It is used to dry antibiotics, vegetables and fruits, etc.

3) The water-containing biological sample is frozen and fixed, and the water in the sample is directly sublimated by ice under the condition of low temperature and high vacuum to achieve the purpose of drying, and the sample is not deformed by the action of surface tension in the drying process.

Process: 1. Freezing of samples For those with ultra-low temperature freezers in the laboratory, it is recommended to store them in ultra-low temperature freezers for freezing. The pre-freezing time must be sufficient to ensure that the sample is fully frozen.

2. Vacuuming, the vacuum degree determines the degree of dryness of the sample, and the product must be sealed.

3. Drying, the water content of different samples is different, and the drying time is not the same, to speed up the drying process, you can match the separator heating system to accelerate the drying.

Freeze-drying is a physical process, which only extracts the water in the ingredients, and the nutrients, color, aroma and taste in the ingredients are well retained. The freeze-dried ingredients remain the same in volume and are loose and porous, extremely light in weight, crispy and easy to chew, and can be restored to their freshness after being soaked in water. For example, the freeze-dried salmon & chicken is made of fresh deep-sea salmon and high-quality chicken breast imported from abroad, without adding any additives such as attractants and preservatives, and is oil-free and salt-free, which is an ideal natural pet food.

It is estimated that many friends have heard of or personally bought freeze-dried fruits, such as freeze-dried lemon slices, freeze-dried durian, freeze-dried figs, etc., their color and shape are very similar to fresh fruits, the taste is crispy, and the shape of the fruit can be restored after soaking. So how are freeze-dried fruits made?

You mean the reason why things that freeze can also dry out, right?

The reason is sublimation.

If it is not icing and drying out, it is vaporization (evaporation to be specific) is not clear.

Freeze-dried food is the abbreviation of vacuum freeze-dried food, also known as FD food. It is a process of directly freeze-drying frozen meat, fruits, vegetables and other raw materials under a vacuum environment. In the freeze-drying process, the ice crystal moisture in the frozen raw materials does not melt into water, but is directly sublimated into gas and dried naturally.

The whole drying process is carried out at a low temperature, which takes about 24 hours, and only the water is drained, and the nutrients in the ingredients are well retained, which is a very meticulous and demanding procedure to ensure that the product is in a "fresh" state, and then enters the packaging process.

The freeze-drying process is currently a relatively advanced processing technology in China, which is applied in many industries, the most common is the beef package in instant noodles, as well as the freeze-dried bento rice, fruit snacks and so on placed in the supermarket, and the application in the field of pet food has also begun to heat up in recent years.

Freeze-dried pet food will generally use pure natural livestock and poultry liver meat, fish and shrimp, fruits, vegetables as raw materials, without adding any preservatives and pigments, and use vacuum freeze-drying process to completely kill the microorganisms and bacteria that may exist in the raw materials, which is very safe for hairy children.

WDJ (2014) recommends that freeze-dried pet food is the freshest, least processed, and nutritionally balanced pet food, in addition to homemade pet food.

1.Rui Meng Rymon Chicken Chicken Freeze Dried.

This chicken freeze-dried chicken is specially selected from the full-age chickens of Nonghu family, which can help enhance the cat's immunity and disease resistance, and can also enhance intestinal immunity, meet the daily nutritional needs of kittens, and make cats not easy to get sick and diarrhea.

And the freeze-dried chicken can supplement additional amino acids and proteins, the nutritional content of full-age chickens is higher, and it is not a broiler that is boosted by hormones, the fresh meat quality is more chewy, and after it is made into freeze-dried, the freeze-dried chicken tastes fragrant and crispy, which is also good for the health of cats.

2.Miao sentence pet freeze-dried.

Be loyal and conscientious to please the Lord, eat dry, soak in water, and end the meow to the unhappiness.

There are edges and corners, scientific feeding knowledge, and remember that snacks cannot replace staple foods.

3.Wess freeze-dried.

The meat source can be traced back to high-quality chicken, full of chicken aroma, based on high-quality chicken, unstoppable delicious animal protein, balanced ratio of a variety of nutrients, cat's diet is a good staple food, helping healthy growth. -35 Nutrition process, 24-hour vacuum dehydration, 1g freeze-dried = 5 times fresh meat.

Vital Essentials has always adhered to independent R&D and manufacturing, third-party foundry, with advanced freeze-drying equipment, independent R&D team, independent production and packaging workshop can be traced back to every step to ensure the safety and health of products, from organic and natural health.

5.Fleett lyophilized.

What kind of food is Flegat's "Full Price High Meat Natural Grain?" It is a high-end meat cat food with fresh meat instead of meat meal, 70% high fresh meat added, fresh meat instead of meat meal, with 15% fruits and vegetables, and 15% balanced nutrients to meet all the nutrients needed for cat growth.

<> lyophilization is made using vacuum freeze-drying technology. It is a new drying method that freezes aqueous materials into solids, and uses the sublimation properties of water under low temperature and low pressure conditions to dehydrate the materials at low temperature and achieve drying. In terms of preserving the nutrients of the food, the cooking time when cooking is greatly reduced.

The freeze dryer is also known as the freeze dryer, which is a technical method to pre-freeze the water-containing items and then sublimate the moisture in a vacuum state to obtain dry items.

Application of lyophilizer.

Application in medical field: The use of lyophilization technology can be used to preserve various organs such as blood, arteries, bones, **, corneas, etc. for a long time. When lyophilized, the cells are not destroyed, and the organism can be resurrected after tax enrichment.

For example, lyophilized bones can be stored at room temperature or in the refrigerator for up to 2 years, or even longer.

Application in the production of Western medicine: multi-feeding powder injection. Antibiotics, central nervous system drugs, vitamins and tumor drugs are the most common. For example, penicillin, percolta.

In the application of traditional Chinese medicine, in recent years, the lyophilization method has begun to process Chinese patent medicines, which are then made into powder after impregnation, extraction, filtration, concentration and freeze-drying.

Freeze dryingFreeze drying refers to the process of removing water or other solvents from frozen biological products by sublimation. Sublimation refers to the process by which a solvent, such as water, like dry ice, changes directly from a solid state to a gaseous state without going through a liquid state. The resulting product is called lyophilizer, and the process is called lyophilization.

Traditional drying causes the material to shrink and destroy the cells. When the ice sublimates, it leaves pores in the dry residue. In this way, the integrity of the biological and chemical structure of the product and its activity is preserved.

For this purpose, lyophilization is used to prepare tissue samples for structural studies (e.g. electron microscopy studies). Under natural circumstances, this process is slow and unavoidable.

Freeze Drying System: A basic freeze drying system consists of: a drying chamber or a multi-manifold.

A vacuuming system overcomes obstructions and accelerates gas flow. A heat source provides energy. A cryogenic condenser to maximize the vapor pressure differential and capture the vapor to freeze it to avoid water vapor contamination of the vacuum pump.

Steps of Freeze Drying The freeze drying process consists of three steps: Pre-freezing, which prepares the sample for the subsequent sublimation process. It needs to be packed into a suitable container and then pre-frozen before it can be sublimated and dried.

The pre-freezing process not only protects the main properties of the substance; Moreover, it is necessary to obtain a reasonable structure of the frozen product to facilitate the sublimation of moisture; It is also necessary to have the right amount of filling for future application.

There are usually two ways to divide the product: bulk and bottle. Bulk can be in metal plates, lunch boxes or glassware; Bottles come in glass bottles and ampoules.

The product is dispensed into a container with a certain ratio of surface area to thickness. The liquid evaporates rapidly under a vacuum, absorbing its own heat and freezing. The centrifugal force of the rotation prevents the gas in the product from escaping, allowing the product to freeze "calmly" into a certain shape.

Freezing can have a certain destructive effect on cells and living organisms, and the mechanism is very complex. There is no unified theory, but it is generally believed that it is mainly caused by mechanical and solute effects. This is followed by solidification of the eutectic mixture.

In general, the larger the ice crystals, the easier it is for the cell membrane to rupture, resulting in cell death; Ice crystals are small, and there is less mechanical damage to cell membranes. Such as glycerol, dimethyl sulfoxide, sugars, etc.

Astronaut freeze-drying technology can also be called minus 40 degrees freeze-drying technology, can retain the nutrients of food to the greatest extent, but also retain the freshness of food, fresh food immediately after picking quick-freezing (as low as 40), and then the ice-like ingredients through vacuum dehydration technology will be solid water directly sublimated into a gaseous state, without liquid state, so that the tissues in the food will not be damaged.

Alkaline Age has applied this technology to it, retaining the nutrients of its 70 foods.
