What are Tamakona and Milkona

Tamakona and Milkona are innovative products designed to streamline your oral food challenge tests and support patients and their families by simplifying daily intake at home. 

Tamakona is a cooked whole egg powder, and Milkona is a skimmed cow’s milk powder. Both products are foods that are precisely quantified for protein denaturation and protein content.

How Tamakona and Milkona Can Help You


1. Simplifying Oral Food Challenge Tests in Medical Facilities:

Tamakona revolutionizes the process of conducting food challenge tests in medical settings. With no need for complex measurements, Tamakona can be quickly and easily dissolved in a small amount of water, making the preparation of food challenge tests straightforward and efficient.


2. Making Home Consumption Easy and Safe:

3. Facilitating Early Introduction of Allergenic Foods in Infants:

Evidence 2 : Timing of onset of allergic symptoms following low-dose milk and egg challenges. Yanagida et al. Pediatr Allergy Immunol 2021; 32: 612-5

We conducted an observational study of OFC with Tamakona 250 and Milkona 100 on children with a history of reaction or sensitization proven by elevated IgE level. Out of 563 children, 53 (9.4%) passed the OFC using Tamakona 250, while 20 out of 103 (19%) passed the OFC using Milkona 100. The symptoms appeared after 60 minutes (median) and 30 minutes (median) after loading Tamakona 250 and Milkona 100, respectively. In conclusion, during OFC, allergic reactions to milk appear and resolve sooner than reactions to hen’s egg, regardless of the total amount of food protein ingested and its form (unbaked vs. baked in a grain matrix). Our findings can help improve the safety of OFCs. We also confirmed that the test can be safely administered to children with or suspected of having hen’s egg or cow’s milk allergy.

Evidence 3 : Threshold and safe ingestion dose among infants sensitized to hen’s egg. Mitomori et al. Pediatr Allergy Immunol 2022; 33: e13830

The study analyzed the outcome of a stepwise OFC in infants who had not eaten hen’s eggs but who were sensitized to egg white-specific IgE. The enrolled infants had a median age of 9.9 months, with a total IgE level of 101 IU/mL, egg white-specific IgE level of 18.0 kUA/L, and obomucoid-specific IgE level of 0.99 kUA/L. A low dose OFC as part of the stepwise OFC was performed using with Tamakona 250. Out of the 87 patients, 12 (14%) failed the low dose OFC, and one patient (1.1%) required an adrenaline intramuscular injection. Subsequently, a moderate dose OFC with Tamakona 750 was performed on 75 patients, and 9 (12%) failed. The study showed that a stepwise OFC performed on infants who were not fed and had IgE sensitization was relatively safe, with many children avoiding complete elimination.

Evidence 4 : Safe egg yolk consumption after a negative result for low-dose egg oral food challenge. Yanagida et al. Pediatr Allergy Immunol 2021; 32: 170-6

A clinical study was conducted with 276 subjects, who had a median age of 1.2 years, a total IgE of 104 IU/mL, egg white-specific IgE of 14.7 kUA/L, and obomucoid-specific IgE 5.3 kUA/L. he subjects were instructed to consume egg yolk splice at home after a low dose OFC with Tamakona 250 was negative. Out of the 276 subjects, only 6 (2.1%) experienced minor symptoms at home. Among these, 5 were able to continue consuming the egg yolk binder without any issues, while 1 patient experienced mild respiratory symptoms, resulting in the complete elimination of the egg yolk binder. Based on the above findings, it is considered that egg yolk bridges can be safely consumed if the Tamakona 250 OFC is negative.

Note

These products can be used in OFC as well as other egg- and milk-containing foods. Allergic symptoms may be induced if they are ingested by a person suffering from an allergy. OFC is a medical procedure conducted by physician experts at a medical institution under the clinical guidelines and should not be conducted by parents or guardians at home. If parents or guardians have any concerns about food allergies, please consult your home doctor or a specialist nearby.
