Protein, High Fiber Biscuit or Sweet (1999)

Jordan imports big quantities of sesame in order to use it in food industries, such
as halva, sesame pulp (Tahina), bakery products and sesame oil. The presscake of oil
extraction contains a high percentage of protein (30%) and fat (27%). It has also a high
moisture content (30%), which leads to fast deterioration.
The aim of this study was to find out methods to extend the shelf life of Kosba to
test its use in the production of high protein, high fiber biscuits or sweets, as a low-cost
source of protein.
Two methods for preservation were found suitable:
1. Mixing of fresh kosba with wheat bran in different ratios that were
extruded through a meat mincer to get a homogenous pelleted, semi dried mixture,
which could be easily air dried.
2. Drying fresh kosba in the sesame roaster, which is available in every oil
mill, at 100°C for one hour.
Different recipes were tested and modified for the utilization of the dried and
finely milled kosba in the production of high protein, high fiber biscuits.
The best developed biscuit formula that gave the highest sensory quality was
obtained when using (23%) sesame bran mix of 2 kosba: 1bran, (18.5%) wheat flour,
(9%) palm oil, (20%) sugar, (6%) water, (4.5%) whole eggs, (18.5%) whole milk
powder, (1.3%) baking powder and 1.3% vanilla sugar preparation.
The developed biscuits contained (16.6%) protein, (19.5%) fat, (2.7%) crude
fiber, and (53%) carbohydrate; the dietary fiber was estimated (10%), thus the
produced biscuits are considered a high protein high fiber product.
The developed biscuits were stored in paperboard boxes for more than six
months, without recognizable drop of the sensory quality, although the acidity of the
extracted oil increased from (1.1%) to (2.8%). This indicates a long shelf life if the
product is packaged in proper hermetic containers.
