Description

Composition for mulberry beverage which can be eaten in space environment and method for preparing the same {Composition for mulberry beverage consumable in aerospace environment and method for preparing the same}

The present invention relates to a composition for Audi beverages that can be eaten in a space environment, and more particularly, to a composition for preparing an Audi beverage that can be safely and easily eaten in a non-gravity space environment by using radiation. It relates to a manufacturing method.

In general, space food refers to food suitable for the space environment, and since there is no refrigerator in the spaceship, it must be able to be stored for a long time in a temperature-changing environment. Consists of food products that can be stored for up to 5 years and must comply with stringent microbial standards for long-term storage. It is also recommended that it be strictly hygienically controlled and manufactured completely aseptically to protect astronauts from food poisoning by pathogenic microorganisms that may exist in space foods.

In the US, on February 26, 1995, the U.S. Food and Drug Administration (FDA) decided that frozen, packaged meat for NASA's space flight program would be used. Radiation was approved, and NASA, in collaboration with the US Army Natick Institute of Technology, developed a space steak and BBQ by irradiating radiation for sterilization of meat.

On the other hand, the radiation food irradiation technology for controlling microorganisms irradiates 0.01kGy to 50kGy of energy from radioactive materials such as gamma rays (Co-60 or Se-137), X-rays or electron beams, that is, ionized radiation energy. Irradiation to foods in dose is used for suppressing germination of foods, delaying maturity, controlling parasites and pests, sterilization of rot and pathogenic microorganisms.

Conventionally, chemical fumigants such as ethylene oxide have been used for sterilization of household goods and foods, but ethylene oxide fumigants are known to harm humans and destroy the environment, and in most developed countries, they are economically efficient and harmless to humans. Radiation food irradiation methods are actively used.

Taking advantage of the above-mentioned radiation technology, NASA has been conducting various researches with radiation technology as a core technology in space food development since the 1960s in collaboration with the Natick Research Institute. In addition, because food-borne diseases that may exist in space may threaten the safety of astronauts, irradiation technology is being researched as a processing method to secure microbiological safety. Proven.

Example 2 Raw Material Mixing

5.52 g of the Audi powder, 20 g of white sugar, 0.45 g of citric acid, and 0.03 g of pectin were added to a blender to uniformly mix for 5 minutes to prepare an Audi beverage powder.

Example 3 Vacuum Packaging

26g of the Audi beverage powder was filled in a package for easy eating in a space environment, and vacuum packed using a vacuum packaging machine. 2 shows an example in which vacuum packaging is completed.

Example 4 Irradiation

Irradiation was performed at room temperature (12 ± 1 ° C) using gamma-ray irradiation facilities (source 300,000 Ci, Co-60) of the Korea Atomic Energy Research Institute Jeongeup Institute of Radiology, 1kGy, 2kGy, 3kGy, 4kGy and The total absorbed dose of 5 kGy was carried out, and the absorbed dose was checked using a ceric-cerous dosimeter, and the error of the total absorbed dose was ± 0.1 kGy.

Test Example 1 Microbial Evaluation of Irradiated Audi Beverage Composition

The degree of microbial contamination according to the irradiation dose of the Audi beverage powder according to the present invention was evaluated.

First, the peptone water (0.9) prepared by sterilizing and pre-sterilizing 10 g of the composition for preparing an Audi beverage prepared by performing irradiation in Example 1 so as to have a total absorbed dose of 1 kGy, 2 kGy, 3 kGy, 4 kGy and 5 kGy, respectively, was placed in a sterile bag for sample homogenization. % Peptone) 90mL was added and then homogenized for 3 minutes in a sample homogenizer for analyzing microorganisms (Stomacher) to use as a sample. After diluting the solution stepwise 10 times with sterile peptone water, general aerobic microorganisms were plate counted Agar (PCA, Difco Co., USA), yeast and mold smeared on Potato Dextrose Agar (PDA, Difco Co., USA). It was. Spore-forming bacteria were killed by heating the sample at 80 ° C. for 20 minutes, and then plated on PCA to confirm the generated spores by gram staining.

Culture conditions were 48 hours at 30 ℃ and spore-forming bacteria for general aerobic microorganisms and mold and yeast were cultured at 25 ℃ for 72 hours, colony forming unit (1g per sample) by counting only the medium with 30-300 colonies CFU / g).

Evaluation results of microbial contamination according to the irradiation dose of the above-mentioned Audi beverage powder are shown in Table 1 below.

* ND in Table 1 means a sample in which microbial growth was not detected.

As shown in Table 1, 1.35 log CFU / g general aerobic microorganisms survived in the non-irradiated Audi beverage powder was not detected when irradiated with more than 2kGy gamma. Fungi, yeast and spore-forming bacteria were not detected in both the unirradiated and irradiated groups. As a result, it was judged that the composition for Audi beverage could be sanitized by radiation treatment of 2 kGy or more.

Test Example 2 Evaluation of Sensory Quality of Irradiated Audi Beverage

Audi beverage powder prepared by performing irradiation in Example 4 to have a total absorbed dose of 1kGy, 2kGy, 3kGy, 4kGy, and 5kGy, respectively, and a non-irradiated beverage beverage (irradiated to a total absorbed dose of 0kGy) , Gamma-irradiated non-irradiated sphere) was dissolved in 100ml of water (see FIG. 3), and then sensory evaluation was performed on each of the Audi beverages to evaluate the sensory quality change of the Audi beverage according to the irradiation dose.

The panel for sensory characteristics was selected from 10 sensory testers with 3 years of experience in sensory testing. Each sample provided water cup, spit cup, and mouth rinse water. (Color), Flavor, Sweetness, Sourness, Overall acceptability, Off-flavor were evaluated on a 7-point scale.

Sensuality is very good at this point: 7 points, not good or hate: 4 points, very bad sensory: 1 point.

In Table 2, the non-irradiated group was found to have almost no off-flavor 1.33, and all of the items except the off-flavor showed a score above the average (4.0). The sensory quality of the irradiated groups up to 4kGy showed little change, but the 5kGy group showed lower scores than other groups in the evaluation of color and odor, especially the smell of 1.83 Highest. However, the 5kGy irradiated group also showed no difference between the non-irradiated and irradiated groups in the overall preference, so that the radiation treatment up to 5kGy had little effect on the sensory quality of the Audi beverage powder.
