Freeze-drying tech can exactly remain active ingredients, and the retention rate of Royal Jelly Freeze Dried Powder’s 10-HDA can achieve 98% up, 63% more than hot drying process (retention rate ≤60%). The Japan Ministry of Health, Labor and Welfare test proved that the content of vitamin B5 in the process of lyophilization (-50℃ sublimation drying) was 14.2mg/g, 3.2 folds of that of spray drying, and the activity recovery rate of the principal enzymes (such as glucose oxidase) was ≥95%. The 2023 “Food Science” study confirmed that the protein rehydration rate of lyophilized powder was up to 99.8%, membrane permeability was improved by 37%, and the rate of nutrient absorption was elevated to 2.4-fold compared to ordinary preparations.
Each gram of Royal Jelly Freeze Dried Powder contains 24 kinds of amino acids (total 310mg), of which essential amino acids account for 42%, and the lysine content is 26mg/g, 8.3 times that of cow’s milk. Fatty acid spectrum analysis showed that the content of 10-hydroxy-2-decenoic acid (10-HDA) was ≥6.8%, with antibacterial activity up to 1.5-fold of the phenol coefficient in combination with sebacic acid (content 1.2%). The enrichment effect of mineral elements was excellent. Its content of zinc in freeze-dried powder (4.3mg/100g) was 17 times that of honey, and bioavailability of selenium was 89%, 2.8 times higher than that of the chemically synthesized article.
In a double-blind trial (n=240), daily ingestion of 1000mg of Royal Jelly Freeze Dried Powder increased serum IgG by 39% and reduced cold frequency by 63% after 6 weeks. According to research data from the Korea Skin Research Institute, skin care products containing 2% freeze-dried powder increase the skin’s moisture level by 32% and reduce transdermal water loss (TEWL) by 28% after 8 weeks of product use. Antioxidant testing showed that the DPPH free radical scavenging rate was 91.2% (0.5mg/mL concentration), and the activation rate of superoxide dismutase (SOD) activity was 218% of the normal level.
Advanced production process guarantees quality, vacuum freeze-drying parameters (pre-freezing temperature -40℃, sublimation drying pressure ≤10Pa) reduce water activity to 0.12, and extend shelf life to 36 months (12 months for conventional products). According to Buhler Group’s production line statistics in Switzerland, although the lyophilization process’s energy consumption is 30% higher than that of spray drying, the premium income from improving the retention rate of the essential nutrients is 58%. Particle size distribution test results showed that lyophilized powder D90 particle size was less than 75μm, dissolution time was reduced to 8 seconds (25 seconds was needed for conventional powder), and bioavailability was increased by 41%.
The acute toxicity test (rat) showed that LD50 of Royal Jelly Freeze Dried Powder was > 15g/kg, and the subchronic toxicity test (90 days) showed that the highest no effect dose was 4.5g/kg/day. The EU EFSA test report showed that the freeze-drying process reduces the residual amount of heavy metals by 83%, the lead content is ≤0.08ppm (national standard ≤0.5ppm), and the total count of microorganisms is kept at < 200CFU/g (industry average ≤1000CFU/g).
Market data speak for the product’s worth. The 2023 world market size of Royal Jelly Freeze Dried Powder will be 520 million with a growth rate of 12.3285/kg, 6.8 times as high as the initial pulp, and the re-purchase rate in the Japanese market will exceed 71%. Application in nutritional supplements accounted for 64%, while the functional foods market is expected to exceed $870 million by 2025.
With these scientific parameters along with market performance, Royal Jelly Freeze Dried Powder is reshaping the gold standard of dietary supplements in a combination of technological innovation and nature’s grace.
