Instant Fish Cream Soup:
A Functional Food Formulation
IPRO Utility Model Reg. No. 2-2011-000430
2. Rationale
CVD is the number one killer disease today especially among
the elderly.
Several Several children and other vulnerable groups are
suffering from nutrient deficiency diseases due to wrong food
choices.
Most of the popular or favorite snack items of the youngsters
today as well as meal adjuncts are empty-calorie foods
These contribute to the so-called lifestyle diseases.
3. Functional Foods
“Let Food be thy Medicine and Medicine thy food”
- Hippocrates: the father of Western
medicine
Functional foods - have health benefits: can cure,
alleviate or prevent the occurrence of food-related
illnesses
4. Theoretical Underpinnings
Food, no matter how therapeutic/functional, if not
consumed is of no value.
Incorporating therapeutic foods in an appetizing
and convenient recipe is an attractive option.
Instant cream soup has a positive valuation, easy
to introduce, thus, a good vehicle for functional
foods
5. Objectives
General Objectives: To develop a functional fish-based soup
formulation that could alleviate lifestyle diseases and nutrient
deficiency-related illnesses. Specifically, it aimed to
Develop a fish-based soup formulation that incorporate foods
found to have therapeutic properties like rice bran, soy beans,
milk casein;
Make the formulation easy to prepare and consume (instant),
shelf stable and of optimum sensory quality;
Develop a zero-waste process in the preparation of the fish
components to increase ROI and make the product affordable
6. Functional Foods & Their Nutritional
Contribution
FISH
Findings of Health Professionals (Hasler, 1998)
Fish (omega-3) -eating at least 35 g daily
reduces the risk of non-sudden myocardial
infarction, CVD, cancer and other
7. Functional Foods & their Nutritional
Contribution (James 1989)
Soy Beans/Protein
a hormone (progesterone) analogue – alleviates
post-menopausal syndrome and other related
symptoms
Rich in protein and essential nutrients with no
cholesterol
Alleviates degenerative and life-style-related
diseases
8. Rice Bran
one of the most nutritious foods on earth
contains tocotrienol and oryzanol – 70 times more
potent than vit. E as anti-oxidant
has significant amounts of vit. B species - prevents
beriberi and other vit. B-related deficiency
diseases
its soft fiber is a strong laxative – prevents colon
cancer

18. Levels of use
Level of use and corresponding nutritional
contribution of the ingredients was estimated using
the Philippine Food Composition Table of the FNRI
(1997).
Dried fish components – level must supply at least
one fish serving based on RENI.
Functional ingredients - in significant amount
(≥20% of RENI) to accomplish the intended
therapeutic/physiological benefits (Hasler, 1998)

21. Recommendations
1. Use of the product may be maximized/
prescribed by health professionals as a safer and
cheaper option in solving malnutrition among
children.
2. Other at-risk groups like CVD patients and
related lifestyle disease can benefit much from
continued use of the product.
3. The product may be made as an essential
component of the DSWDs food pack in place of
the empty-calorie foods.
22. 5. A study may be conducted to verify and
strengthen the claims on its therapeutic benefits
particularly on degenerative ailments as well as
nutrient-related chronic diseases.
4. Commercialization of this zero-waste process could
increase ROI and help stabilize the market for fish
especially during a market glut.
6. The product can be made to adhere or comply with
halal and kosher standards to benefit our Moslem
brothers.
The nutrition fact label of the commercial cream soup of the same weight indicated that it contains only 4 grams protein (3% of the RDA), and 2 percent each of the RDA for calcium, iron, total fat and dietary fiber. This clearly indicates that the nutritional contribution of this leading brand is insignificant.
Dried Fish Flakes. The protocept process of deboning the raw fish was difficult as the flesh sticks firmly to the bones. The process was then modified to facilitate deboning and increase recovery of the flesh.
The edible portion (E.P.) or flesh obtained was 50% of the as-purchased (A.P.) weight, which was higher than the food composition table (FCT) value of 46%.
Fish Bone Powder. Oven-dried fish bones produced by the Bench process was hard to grind and darkened during oven drying due to Maillard reaction or non-enzymatic browning of the remaining flesh. To improve the process the bones were repeatedly washed with a small amount of hot water. Flesh in the wash water was recovered by straining. For each kilo of fish, 400 grams of washed bones were obtained. The dried weight was 100 grams (10% of A.P.).
Fish Oil. The initial process resulted to an odoriferous oil. Apparently, the water-soluble odoriferous components of the fish entrails dissolved in the oil leaving an undesirable fishy odor. This was addressed by separating the fatty tissues from the dark-colored intestines. These were boiled to dissolve the fat, cooled, and chilled then the fat was skimmed off. The remaining moisture was evaporated by heating the oil. Since fish oil is rich in omega-3 fatty acids, which is prone to oxidation, it was protected with alpha-tocopherol. The amount of oil obtained from a kilo of fish was 20g.
