Silk Degumming with Dried Latex of Carica Papaya Linn
Silk Degumming with Dried Latex of Carica Papaya Linn

Degumming process is a fundamental finishing process for silk yarn and silk fabric. The main objective is scouring the substrate such as silk gum (sericin) wax and some impurities from silk fiber. The principle of degumming process is breaking the peptide linkage of amino acid in sericin structure into a small molecule which is soluble in water. The hydrolysis reaction performed by acid and alkaline but they have a big problem on the surface area of silk. Proteolytic enzyme be used to solve this problem but it has some disvantages such as it was using a specific condition and expensive. For this reason this research chooses papain enzyme form dried latex of Carica payapa Linn. to degum the raw silk. The efficiency of degumming process was evaluated by determination of tensile strength and staining test with direct dyes (C.I. Direct Red 80). The result was revealed; the appropriate conditions for silk degumming with dried Carica payapa Linn.’s latex be recommended as follows: the amount of dried latex solution of 4 % owf at 75 degree Celsius for 30 minutes in this condition was not harm to strength and fiber surface. The degummed fibers still had lustrous soft and smooth surface.

In this study 14 bacterial strains isolated from gastrointestinal tract of black tiger shrimp (Penaeus monodon) was investigated for their probiotic potential. The results showed that 6 strains namely S1 S3 S6 S7 T4 and T5 were able to degrade 3 nutrient substances including protein starch and lipid among which S3 S7 and S2 were the best tested nutrient-degrading bacteria respectively. Six bacterial strains were unable to lyse red blood cells including S2 S3 T0 T1 T2 and T3. S2 strain showed the strongest antibacterial activity against shrimp pathogenic Vibrio harveyi following an agar overlay technique. Based on environmental tolerance tests S2 and T0 strains grew well under wide ranges of environmental conditions e.g. sodium chloride concentration (0-8%) pH (6-10) and temperature (25-37C). As a consequence S2 strain had the most probiotic potential for shrimp culture owing to no hemolysis of red blood cells inhibition of V. harveyi growth protein and lipid degrading ability and high environmental tolerance for shrimp cultivation. The strain was identified as Micrococcus sp. S2. However additional study focused on immune response nutrient digestibility and growth promotion of the strain should be further performed in marine shrimp.

Foods rich in dietary fiber and antioxidants have attracted great attention to both of consumers and food manufacturers because of their significant health benefits. Increased consumption of dietary fiber improves lowering blood pressure and cholesterol levels. Furthermore it prevent a number of gastrointestinal disorders such as constipation and hemorrhoids. Antioxidants are bioactive compounds that can delay or inhibit the oxidation by inhibiting the initiation or propagation of oxidative chain reactions. These free radical reactions cause human diseases such as cardiovascular disease and cancer. Legumes are an excellent source of compounds having antioxidant. Hence recent research has been focused on the potential utilization of bean coat which was by-products from processing industry to the development of new functional ingredients for food nutrition enrichment. The extraction of bioactive compounds from seed coats are used as a food ingredient for various foods processing such as tofu with soybean hull fiber black bean seed coat in maize flours for the production of cookies and whole wheat bread. Therefore research and development of new functional foods from bean seed coat used as ingredient for the preparation of food products to improve food nutrition will be necessary to provide for Industrial manufacturing according to demand and sufficient for healthy food consumption in the future.

The objectives of this research were to study the optimal formulation of imitated peanut butter spreads on bread productsfor (1) Study the right recipe of bread from rice riceberry (2) Study the increasing stability of the product Development of Imitation bread spreads from broken riceberryrice (3) Study the nutritional value of the product Development of Imitation bread spreads from broken riceberry rice (4) Study microbial transformation and during storage of candy paint problems of the product Development of Imitation bread spreads from broken riceberry rice (5) Study the adoption of consumer products for the product Development of Imitation bread spreads from broken riceberry rice. The study indicated that the stabilization of spreads on bread products from broken-rice rice berry and the nutritional value of the product. Take the broken-rice to the appropriate amount for the basic formula bread. Perform quality testing by measuring color viscosity and sensory evaluation (9-point hedonic scale). From the results found that the mixture of developed butter spreads on bread products made from broken-rice gained the highest score in terms of overall liking at 7.94 points. The formula consists of riceberry 30.7% water 27.7% condensed milk 29.5% butter 5.9 % cocoa powder 1.9% milk powder 1.9% vanilla 1.1 % sugar 0.9% salt 0.4% and SP 1.2% additives. For the physical properties of the developed product showed that this lightness (L*) redness (a*) and yellowness (b*) were 24.62 11.89 and 11.85 respectively while a viscosity of 26727 cp. The nutritional value of 100 g of this product contained protein fiber carbohydrate and carbohydrate at 2.56 0.96 2.77 and 47.38 g respectively Moreover its contained 0.81 mg vitamin E and 95.80 mg Antioxidant. After storage at 4.1 ๐C for 6 weeks this product was shown to be safe for consumption. It passed quality criteria of Thai community product standard (TCPS 1012/2548). Regarding the acceptance of consumers which were a general consumer groupof 100 food tasters the majority were female with a percentage of 77%. The highest age range was 30-39 years and 40-49 years with a percentage of 25%. Most consumers had an educational level a bachelor’s degree with a percentage of 59% These consumers are state enterprise officer with a percentage of 52% and incomes were higher than 25000 baht per month with a percentage of 36%. Respondents mostly expressed opinions about The Development of Imitated Spreads on Bread from Riceberry in terms of innovative 100% of them accepted the product and 97% decided to buy The Development of Imitated Spreads on Bread from Riceberry.
