Study of fatty acid content was conducted in six Indonesian fish oils taken from Surabaya, Sorong, Garut, Banyuwangi, and  fish oil standard. The acid and peroxide values were a main parameters which affecting the quality of the fish oil. These parameters were set using the method stated on the SNI No. 01-3555-1998. The oil containing omega-3 such as EPA and DHA is beneficial for health. The study of fatty acid content in six fish oils were analyzed by GCMS Shimadzu QP 2010 ULTRA with FID Detector. RTX-5 were used as a column (diphenyl dimethyl polysiloxane  as a solid buffer, size length 30 m, diameter 0,25 mm, and He as a gas mobile phase).  The results showed that acid values for oil 1, 2, 3, 4, 5, and 6 were 0.55%, 0.50%, 0.48%, 0.55%, 0.48%, and 0.58%, respectively. While the peroxide values were 5.67, 4.72, 4.45,5.01, 4.85, and 5.27 meq/kg, respectively. GCMS analysis showed that fish oil 1, 2, 3, and 4  very dominant containing squalene of  29.45%, 32.34%, 21.07%, and 43.49%, respectively. While oil 6 contained EPA of 8.97% and DHA 6.56%, and that was the highest compared with other oils. However, oil 6 also contained a trans fatty acids i.e., elaidic acid of 26.8% and trans-13-docosanoic acid of 0.9%. For comparison, natural oil 5 was rich of linoleic acid  (39.58%).  The GCMS's analysis results proved that the oil 6 made from lemuru had a big potency to be developed for an Indonesian fish oil export comodity.

The aim of the study was to assess the influence of the addition of fish raw materials (roe or fish meat) on the quality and nutritional value of pork pâtés. The control group (n = 4) consisted of pork pâtés, I experimental group (n = 6) of pâtés with 20% addition of roe (perch and pike), and II group of pâtés with 20% addition of fish (perch and pike meat) (n = 6). The pâtés’ pH, color, and profiled texture analysis were instrumentally measured and water, protein, fat, ash, and fatty acid content were determined by reference methods. To assess the oxidative stability of lipids the measurement of peroxide number, thiobarbituric acid reactive substances and content of conjugated dienes and trienes was used. The degree of fat hydrolysis was determined on the basis of acid value. Sensory analysis was carried out using the scaling method, taking into account 12 unit quality characteristics. Products with roe and meat contained less fat (accordingly 15.9% and 14.1%) and showed lower calorific value (accordingly 225.6 and 208.6 kcal/100 g) compared to pork pâtés (20.2% of lipids, 267 kcal/100 g). Moreover, the addition of fish raw materials improved the index of nutritional quality for protein (from 3.2 to 3.9) and beneficially reduced the nutritional index for fat (from 2.2 to 1.9). Fish constituents modified, to a certain extent, the color, texture, and sensory properties of pâtés, while maintaining full acceptability in consumer assessment. The addition of fish roe significantly increased the healthful quality by improving the fatty acid profile of pâtés, in which the significantly highest content of n-3 fatty acids, including eicosapentaenoic and docosahexaenoic acids (accordingly 252.21, 43.17, and 107.94 mg/100 g product), as well the highest concentration of saturated branched chain fatty acids were determined (18.75 mg/100 g product).

Western diets are typically low in ω-3 fatty acids, and high in saturated and ω-6 fatty acids. There is a need to increase dietary ω-3 fatty acid content. Chia (Salvia hispanica L.) has the highest botanical source of alpha-linolenic acid (ALA) known, and recently has been receiving more attention because of this. Feeding ALA to animals has been shown to increase the ω-3 fatty acid content of the foods they produce, and hence offers consumers an easy way to increase their intake of ω3 fatty acids without altering their diet. Broilers were fed rapeseed, flaxseed, chia seed and chia meal to assess the ability of these feed ingredients to increase the ω-3 fatty acid content of the meat, and also to determine whether any negative effects on bird production would arise. Flaxseed produced significantly (P < 0.05) lower body weights, weight gains and poorer conversion ratios than did the other feeds. Except in the case of the chia meal with the dark meat, the chia seed significantly (P < 0.05) reduced the saturated fatty acid (SFA) content of the white and dark meats compared with the control diet. Adding ALA increased the ALA, LCω-3 fatty acid and total polyunsaturated fatty acid (PUFA) ω-3 fatty acid content of both meat types, except in the case of the white meat of the birds fed rapeseed. Chia seed gave the highest total PUFA ω-3 increase, yielding 157 and 200% increases for the dark and white meat, respectively, compared with the control. The ω-6:ω-3 and SFA:ω-3 ratios dramatically improved in both types of meat when chia seed, chia meal or flaxseed was added to the diet. The study also showed that not all ALA-rich seeds are biologically equivalent sources in terms of producing ω-3 enriched broiler meat. Chia proved to be superior to the other sources examined in this trial. Key words: Chia seed, flaxseed, rapeseed, omega-3, alpha-linolenic, broiler meat, fatty acid

The effect of feeding semipurified diets enriched in linseed (rich in C18:3, omega 3 fatty acid) or fish (rich in C20:5, omega 3 and C22:6, omega 3 fatty acid) oil with and without cholesterol supplementation on the desaturation of linoleic acid (C18:2, omega 6) by rat liver microsomal fractions was investigated. Animals fed diets supplemented with beef tallow were used as equal-energy controls. Both linseed-oil and fish-oil diets, without added cholesterol, decrease conversion of C18:2, omega 6 fatty acid to gamma-linolenic acid (C18:3, omega 6). Reduction in delta 6-desaturation was significantly greater for animals fed the diet containing fish oil than with animals fed the linseed-oil diet. The major effect of cholesterol supplementation was to decrease the rate of desaturation of C18:2, omega 6, when fed in combination with the beef-tallow diet, whereas delta 6-desaturation was unaffected when cholesterol was fed along with diets high in omega 3 fatty acids (linseed oil or fish oil). The activity of the delta 6-desaturase in vitro is consistent with the fatty acid composition observed for the microsomal membranes on which this enzyme is localized. Dietary linseed oil and fish oil lowered the arachidonic (C20:4, omega 6) acid content of rat liver microsomes, with an accompanying increase in membrane eicosapentaenoic (C20:5, omega 3) and docosahexaenoic (C22:6, omega 3) acid content, in comparison with the group fed beef tallow. Inclusion of cholesterol into the beef-tallow or linseed-oil diets resulted in decreased membrane C20:4, omega 6-fatty-acid content, with concomitant increase in C18:2, omega 6-fatty-acid content. However, addition of cholesterol to the fish-oil diet did not alter the microsomal membrane content of C20:4, omega 6 fatty acid. Thus it is suggested that (1) the decrease in prostaglandin E2, thromboxane and prostacyclin levels generally observed after fish-oil consumption may be at least partly due to inhibition of C20:4, omega 6-fatty-acid synthesis from C18:2, omega 6 fatty acid; and (2) consumption of fish oil prevents the further decrease in C20:4, omega 6-fatty-acid levels by dietary cholesterol that is apparent when cholesterol is fed in combination with diets high in saturated fat or C18:3, omega 3 fatty acid.

Functional Drink

This article mainly introduces the necessity of the emergence of functional foods and the current market development. Using chia seeds as the characteristic raw material, adding apple juice and hawthorn juice, it is developed to be suitable for subhealthy people, obese people, diabetes and cardiovascular patients.Functional beverages refer to beverages that regulate human body functions to a certain extent by adjusting the composition and content ratio of nutrients in the beverage. In recent research hotspots, chia seeds are often developed and applied by nutritionists or other nutrition enthusiasts because of their rich nutritional value. Chia seeds are rich in a variety of unsaturated fatty acids, accounting for about 80% of the total fatty acid content, of which omega-3 and omega-6 unsaturated fatty acids are the most content, 68% is α-linolenic acid, which is the most abundant omega-3 fatty acid content of the food. Each 100g of chia seeds contains about 16-25g of protein and about 26-40g of dietary fiber, including all 8 amino acids needed by the human body. In addition, it is also rich in vitamins and minerals, as well as a variety of natural antioxidant ingredients, with high-quality antioxidant functions. This makes the ability of chia seeds to maintain blood sugar stability, protect the heart, cerebrovascular, and promote gastrointestinal motility and bone health cannot be underestimated.Hawthorn contains a large amount of vitamin C, carotene, organic acids and other nutrients, combined with cellulose, pectin and organic acids in apples, can further assist chia seeds to improve gastrointestinal conditions and promote gastrointestinal motility, while soluble fiber Vegetarian can regulate blood sugar.This article chooses apple and hawthorn as flavor bases, oligosaccharides (FOS) as sweeteners, resistant starch and guar gum as composite stabilizers, to produce a chia seed functional drink to reduce weight and improve heart and brain Vascular health problems. In the extremely poor analysis of the orthogonal test results of the chia seed functional drink, the best sample formula.
