infausta our results are somewhat CHIR99021 FDA higher than reported in fruits from Malawi [5], Botswana [8], and Tanzania [17]. For L. kirkii, the dry matter content was comparable with the literature data [1]. The average dry matter content of A. digitata kernels was 92.0%, which is in agreement with other results, ranging from 85% to 97% [1, 7, 9, 14, 15, 18�C21]. The average dry matter content of S. birrea kernels was 94.3%, which is at the same level as the results from other reports [1, 11, 15, 22, 23].Table 1Dry matter content, protein, fat, and ash expressed in g/100g dry matter (n = 3). The protein content of the pulp was low in general (below 5%) for all the fruits. This is in agreement with results of other reports, [1, 5, 7, 15�C18]. For A. digitata, however, there is a report showing a much higher protein content, 15.

3% [24]. The protein content in the pulp was significantly lower than in the corresponding kernels (P < 0.05). A. digitata kernels contained on average 39.3% protein and S. birrea kernels 32.6%. For A. digitata, our results are in accordance with other results [7, 18], but there are also reports showing lower protein content, 13�C27% [14, 15, 19, 21], and one report showing higher protein content, 48.3% [20]. The protein content in the kernels of S. birrea was at the same level as found in another report [23]. The high protein content in the kernels is at the same levels as reported for soya beans, around 33% [11], which means that the kernels may be a potential source of protein and can be used to improve the diet in rural communities.

For example, a daily intake of 100g of fresh pulp from the wild fruits studied here would provide around 2�C11% of the recommended daily intake (RDI) for children from 4 to 8 years old, while 20g of A. digitata or S. birrea kernels would provide 32�C39% of the RDI for children of the same age [25]. The protein quality of the kernels seems to be good since high amounts of the essential amino acid lysine as well as of arginine, glutamic acid, and aspartic acid have been reported for A. digitata kernels [15]. S. birrea kernels have been shown to contain high amounts of the essential amino acids phenylalanine, lysine, and threonine [3, 6].The fat content in the pulp was below 2% for all the fruits. The literature data on A. digitata and S. birrea pulp generally show fat contents below 1% [1, 7, 14�C16, 18], while some reports show a higher fat content in A.

digitata, 4% [5, 17, 24]. The pulp of wild fruits is typically low in fat and protein [5], while the kernels are good sources of fat and protein [10]. In the present study, the average fat content was 38.0% in kernels of A. digitata and 60.7% in kernels of S. birrea, and the fat content in the kernels was significantly higher than that in the pulp (P < 0.05). Cilengitide Our data on kernels are in agreement with results from other studies [1, 3, 22, 23], while the fat content was lower in two reports [20, 21] and higher in one [18].
