ABSTRACT This work presents findings on hot water and alcohol methods of extraction of Tetrapleura tetraptera (Oshorisho) extracts used to flavor pineapple and pawpaw fruit juice samples separately. The acceptability of the extracts on pineapple and pawpaw juices were evaluated. The work addresses the concern on the toxic effects of artificial sweetness used to flavor fruit juice and the need to replace them with natural alternatives. The extraction was done on freshly harvested fruits of Tetrapleura tetraptera (Oshorisho). The major compounds identified in the fruit of Tetrapleura tetraptera (Oshorisho) were tartaric acid, glucose, sucrose and fructose. Tetrapleura tetraptera (Oshorisho) had a titratable acidity of 0.035 %.The microbial analysis on the spice extract showed that there was 8.0x104cfu/ml and 2.0x102cfu/ml of total bacterial and total fungal count respectively. This is a microbial contaminant but the result is within the limit for human consumption. Tetrapleura tetraptera (Oshorisho) extract in fruit juice samples increased the sugar level from 19.5 % - 20 % in pineapple juice containing hot water extract, and from 19.5 % - 21.5 % with ethanol extract. Sugar level in pawpaw increased from 15.0 % - 16.0 % in juice containing hot water extract, and 15.0 % - 16.05 % in juice containing ethanol extract. Sensory evaluation of these extracts showed that the hot water extract was preferred in pineapple juice to that of pawpaw juice and there was no significant difference at (p≥0.05) with 100 % pineapple fruit juice.

This Minnesota animal health vision document is the culmination of more than a year of research and disciplined examination of the world that is evolving to determine how Minnesota’s industry will be impacted by these changes. It is the first paper of its kind that examines six primary bioscience-based industries individually and simultaneously, so that overlapping opportunities can be identified and leveraged. It is intended to help Minnesota decision makers in all sectors involved in the bioscience-based economy. Through the detailed Strategic Flexibility process that has been adopted, information will be made available to leadership so more clear, confident and coordinated decisions about elements of our state’s economic strategy can be made, and our communities’ participation in these industries enhanced. The process is not intended to pick "winners" or "losers" but to make investments that provide Minnesota with the strongest possible infrastructure to help our companies compete now, and in the future, in the industries of their choosing. The goal of this process is to focus on ensuring that Minnesota remains a strong global leader in the animal health industry and helps to shape the industry’s future.
