Description

Technical Field

[0001] The invention belongs to the technical field of compressed food, and in particular relates to a field portable highland barley compressed food and a preparation method thereof. Background Art

[0002] In today's society, with the improvement of people's living standards and their love for outdoor sports and adventure activities, outdoor activities such as hiking, mountaineering, camping, and outdoor exploration are becoming more and more popular. However, the outdoor environment is complex and changeable, and participants face many challenges, among which the supply and preservation of food is a crucial issue.

[0003] Traditional outdoor food has many limitations. Common dry food such as compressed biscuits is easy to carry, but its nutritional content is relatively simple, mainly carbohydrates, lacking high-quality protein, vitamins, minerals and other functional nutrients. Eating this kind of food for a long time cannot meet the needs of outdoor participants for comprehensive nutrition in high-intensity exercise and harsh environments, and can easily lead to physical fatigue, decreased immunity and other problems, affecting the smooth progress of activities and physical health.

[0004] In addition, some common wild foods are not fresh enough. The wild environment often lacks suitable storage conditions, and the temperature and humidity fluctuate greatly, which can easily cause food to spoil and mold. In order to extend the shelf life, some foods will add a large amount of chemical preservatives, which may pose a potential hazard to human health.

[0005] Therefore, the market urgently needs a food product that can provide comprehensive nutrition, can be preserved for a long time in the wild environment, and is easy to carry. Summary of the invention

Control the distance between the spray gun and the compressed food to 18cm, the spray gun pressure to 0.25MPa, and control the film liquid coating thickness to 0.22mm. The coated compressed food is placed in a FG-120 ventilated drying cabinet, set the temperature to 35℃, the relative humidity to 30%, and dry for 2 hours to dry and solidify the film liquid to form a protective film.

[0082] (V) Packaging

[0083] The dried compressed food is vacuum packed, and a food-grade aluminum foil bag with a thickness of 0.1 mm (model: LB-01, manufacturer: Zhejiang Ouren New Materials Co., Ltd.) is used as the packaging material.

The product name "Field Portable Highland Barley Compressed Food", ingredients (pre-ripened highland barley powder, Antarctic krill powder, sea buckthorn fruit powder, oligoxylose, highland barley sprout freeze-dried powder, yak collagen peptide, Medog Dendrobium polysaccharide, quinoa crisps, nano-calcium carbonate, highland barley β-glucan film liquid), weight (marked according to the actual single piece weight), production date, shelf life (12 months) and other information are clearly marked on the packaging for consumers to identify and use.

[0084] In summary, the highland barley in the present invention is rich in carbohydrates. After pre-ripening, it is easier for the human body to digest and absorb, and can quickly replenish energy for outdoor activities. Moreover, the β-glucan and resistant starch in highland barley can increase the residence time of food in the intestines, so that people can have a lasting sense of fullness, reduce hunger, and meet the energy needs of long-term outdoor activities. After quinoa is made into crispy chips, it not only tastes crispy, but also can provide further energy. At the same time, its rich dietary fiber helps to promote intestinal peristalsis, maintain intestinal health, and ensure the normal operation of digestive function in the wild environment. Antarctic krill is a high-quality protein source with a high protein content and contains 8 essential amino acids for the human body. The ratio is reasonable and easy to be absorbed and utilized by the human body. For outdoor activities, high-intensity exercise requires sufficient protein to repair and grow muscles and maintain normal physiological functions of the body. In addition, Antarctic krill powder is also rich in ω-3 fatty acids, such as EPA and DHA, which have anti-inflammatory and cardiovascular protection effects, and help to reduce physical fatigue and damage caused by outdoor activities;

[0085] Yak collagen peptide helps maintain joint flexibility and toughness, reducing the risk of joint pain and injury. At the same time, it can also promote skin elasticity and luster, protecting skin health in dry and harsh environments outdoors; antioxidants can remove free radicals in the body, reduce oxidative stress damage to the body, and enhance immunity. Seabuckthorn fruit powder helps outdoor participants resist the damage of the external environment. In addition, the organic acids in seabuckthorn fruit powder also have a certain natural preservative effect, which helps to extend the shelf life of the product.

[0086] Freeze-dried powder of highland barley sprouts, highland barley sprouts are rich in various vitamins, minerals and bioactive ingredients, such as SOD enzyme, γ-aminobutyric acid, etc. SOD enzyme has a strong antioxidant capacity, which can protect cells from free radical damage and delay cell aging; γ-aminobutyric acid has the effects of calming the nerves, lowering blood pressure, improving sleep, etc., which helps outdoor participants to restore physical strength and mental state when they are tired.

[0087] Oligosaccharides can selectively stimulate the growth and activity of beneficial bacteria in the intestine, regulate the balance of intestinal flora, and improve intestinal function. In the wild environment, irregular diet and limited sanitary conditions may lead to intestinal flora imbalance, and nano-calcium carbonate can be better absorbed and utilized by the human body. In outdoor activities, the body needs enough calcium to maintain bone health and normal physiological functions, especially for people who walk with weight for a long time or perform high-intensity exercise, calcium supplementation is particularly important; Medog Dendrobium polysaccharide: has a variety of health functions, such as enhancing immunity, anti-fatigue, and lowering blood sugar. Highland barley β-glucan film liquid: on the one hand, it can act as a natural adhesive to tightly combine various raw materials together, so that the product is well-formed and easy to carry and eat. On the other hand, highland barley β-glucan forms a protective film on the surface of the product, which can block the invasion of oxygen, moisture and microorganisms, extend the shelf life of the product, and ensure the stable quality of the product in the wild environment.

[0088] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0089] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
