Ingredient information
Sossi contains 80% textured soya protein and 20% Sossi Classic flavour seasoning powder.
Each SOSSI 90 gram packet contains 72 grams textured soya protein and 18 grams seasoning powder.
Sossi’s textured soya protein is manufactured with natural soya beans.
Sossi Classic flavour seasoning powder does not contain any meat products.
Sossi is vegan friendly which means that it can be eaten by anyone including vegetarians.
How to prepare SOSSI
For your family to get the most enjoyment out of SOSSI , it is best
prepared in their favourite stew or relish. Prepare their favourite meal exactly as you normally would, but
simply replace the meat or beans that you would usually add to the
meal with SOSSI Tasty Soya Pieces.
SOSSI is a dry product that will absorb a lot of liquid as soon as it is added to your family’s favourite sauce. The best way to prepare it is to add the SOSSI straight from the packet to the sauce whilst it is still dry so that it absorbs as much liquid and flavour as it can for 2 minutes. After these 2 minutes the Sossi will have soaked up the liquid from the mchuzi sauce and you will need to add at least one cup of water (350ml) or more to bring it back to life, depending on how liquid you would like your Mchuzi sauce. Allow the Mchuzi sauce and Sossi to simmer until it has regained its desired consistency before serving.
Never soften Sossi tasty soya pieces in plain water before adding them to your Mchuzi sauce. Plain water is tasteless, and you want the dry tasty soya pieces to absorb a liquid with a flavour. Hence we always recommend that you soften the dry tasty soya pieces in the mchuzi sauce before adding any water to them.
The instructions on the SOSSI pack are just one example of how
best to prepare Sossi Tasty Soya Pieces. We have chosen
a recipe for onion and tomato stew, which
is a favourite amongst many East African
families, but you can choose any of your
other favourite recipes.
Cooking Tips
Never soak textured soya pieces in plain tasteless water. One of the secrets with dry textured soya pieces is to realize that in its dry form you have an ingredient that will naturally absorb any liquid that is added to it and so you have the opportunity to fill your textured soya pieces with whatever flavour you like.
Another important secret to preparing textured soya protein is to know how to alter the mouth feel. If you like the pieces to be firmer, you can achieve this by frying the soya pieces in vegetable oil. We suggest that when you fry your onions that you add the Sossi tasty soya pieces to the onions just as you are about to finish frying the onions. You will notice how the dry Sossi pieces soak up all the excess vegetable oil. Allow the Sossi pieces to fry for between 30 seconds and 3 minutes with the onions. You will notice that the longer the pieces are left to fry in the vegetable oil, the crispier the mouth feel of the pieces will be after they have been added to the Mchuzi Mix. Sometimes you will want to fry them for only 30 seconds and other times, when you want the pieces to be crispier, you will fry them for up to 3 minutes.
Using SOSSI results in less time required to cook your meal and lower cooking costs. A big advantage to every household is that SOSSI has already been cooked. Sossi only needs to be rehydrated (softened by adding Mchuzi sauce, vegetable oil and flavoured water) as it has already been pre-cooked. It therefore requires no additional cooking and can be added during the cooking process without requiring any additional time to cook.
Other forms of protein such as meat (beef, chicken and pork)
need to be cooked and are usually boiled for
approximately 30 minutes. Beans, lentils
and peas are usually soaked for
8 hours and then boiled for
approximately 30 minutes.
So SOSSI saves at least
30 minutes cooking time
and cooking fuel with
every meal!
Protein comparison with other Legumes (beans)
There are over 800 varieties of soya beans in the world. The protein per 100 grams varies for each variety and there will be small changes from one season to the other depending on factors such as numbers of light hours, rainfall and the quality of the soil in which the crop is grown. Our factory that supplies East Africa sources soya beans with an average protein content of 40 grams per 100 grams.

Amino Acids as building blocks of proteins.
The list and the graph below provide a comparison of the level of the Amino acids in Soy compared with whey and casein, which are two other excellent sources of protein for humans. Soy, casein and whey are considered as “Complete Protein Sources” as they contain significant amounts of all 10 of the essential amino acids our bodies cannot produce.


Casein is the predominant phosphoprotein (αS1, αS2, β, κ) that accounts for nearly 80% of proteins in cow milk and cheese.
Whey or milk plasma is the liquid remaining after milk has been
curdled and strained; it is a by-product of the manufacture of cheese
or casein and has several commercial uses.
Did you know?
Soya Beans are recognised as an ideal rotational crop to be grown with maize and wheat. This is because the root system of the Soya bean is extremely efficient in replenishing nitrogen in the soil. The nitrogen is found in the roots of the soya bean, so it is important that, after the soya bean crop has been reaped, the roots must not be removed from the ground. They should be ploughed back into the soil to achieve maximum regeneration.
Did you know that Soya Beans typically produce 150 times more protein per hectare of arable land compared to cattle production of beef protein per hectare?
Raw Soya beans contain trypsin inhibitors which stop the enzymes in the digestive system
operating so you do not digest your food. Soya beans also contain lipoxygeneases which are
classified as growth inhibitors which cause oxidation of the soy oil which change the taste.
Soya beans must be cooked to remove these trypsin inhibitors and lipoxygenases thereby
making them digestible. The best method is to soak the Soya Beans for 8 hours and then boil
them for 25 minutes. If you don’t soak the dry soya beans first, they require 3 hours of boiling
due to the slow rate of hydration which is an inefficient use of energy. Sossi textured soya
protein has been precooked and does not require further cooking to be eaten.
