Summary: | Consumers are well-informed about food additives and it is likely that they prefer natural additives over their synthetic analogues. Antioxidants represent a major class of food preservatives, among which tocopherols stand out as one of the most important examples. Interestingly, these compounds are present in relevant amounts in the mycelia of
in vitro
cultured mushrooms. Accordingly, the mycelia from
Ganoderma lucidum
,
Pleurotus ostreatus
and
Pleurotus eryngii
were used as alternative sources of tocopherols. These extracts were incorporated into different yogurt formulations, which were further compared among each other and with yogurts containing commercial α-tocopherol (E307), regarding their nutritional parameters, fatty acid profile and antioxidant activity. The proposed approach was validated as an effective functionalization strategy, particularly in the case of the
G. lucidum
mycelium, which showed the highest antioxidant potential, most likely as a result of its tocopherol profile. Furthermore, yogurts prepared with each mycelium extract allowed maintaining the nutritional properties observed in the "blank" yogurt formulation.
The tocopherol extract from
Ganoderma lucidum
proved to be the most suitable choice as a new functionalizing agent to be incorporated in yogurt. |
