A method to eliminate pathogenic (致病的) bacteria and inhibit their growth during storage of weaning preparations can benefit nutrition and health in young children considerably. Use of fermented foods for feeding children of weaning age appears to be an effective solution. Fermented foods have lower levels of diarrhoeal germ contamination, they are suitable for child feeding, and can be safely stored for much longer periods of time than fresh foods. The practice has been a traditional way of food preservation in many parts of the world. The anti-microbial properties of fermented foods and their relative higher safety—documented since the early 1900’s—have been indicated in a number of studies.

In Ghana, it is common to ferment maize dough before cooking it as porridge. In Kenya, cereal-based porridge and milk are traditionally fermented. Preserving milk in the form of yogurt has been known to many households living in hot climate.

What are the underlying mechanisms by which fermentation processes help to prevent or reduce contamination A possible answer suggests that during the fermentation process foods become more acid. This explains why diarrhea-causing bacteria are not able to grow in fermented foods as rapidly as in unfermented ones. It is also hypothesized that some of the germs present in the foods are killed or inhibited from growing through the action of antimicrobial substances produced during fermentation. The fermented foods can, therefore, be kept for a longer time compared to fresh ones. It has been shown that while contamination levels in cooked unfermented foods increase with storage time, fermented foods remain less contaminated.

Whatever the underlying mechanisms, the fact is that the exercise reduces contamination without adding to the household cost both in terms of time and money. Its preparation is easy. The cereal flour is mixed with water to form a dough which is left to be fermented; addition of yeast (酵母), or mixing with a small portion of previously fermented dough is sometimes needed. The dough can then be cooked into porridge for feeding to the child.Although beneficial, unfortunately the practice is going out of fashion, partly because of current emphasis on the use of fresh foods, particularly for children. For example, a study on the use of fermented foods for young children in Kenya, demonstrated that while foods are still frequently fermented at home for child feeding, their use is becoming less popular, particularly in urban area where commercial products are more available. Clearly they now need to be promoted.
