Thai Local Herbs Snack Product (TLHSP) is very popular and has increase tendency the target group in worldwide such as children teenager and adult which live in metropolis. The aim was 1.) to study the formular and condition to produce TLHSP by extruder machine 2.) to study the type and quantity of Thai Local Herbs which was added 3.) to study the shelf-life and type of package to keep TLHSP. The study used CRD to design the method and has a stable variable is 1% CaCo3and varies 2 variables are the ratio between a speed of single screw at 3 levels such as 250 300 and 350 rpm and moisture content of raw material at 3 levels such as 15 17.5 and 20. And this research study about the level of grinded sugar (GS) at 3 levels such as 0 3 and 6 g. which at 3 g. the TLHSP had well scores of 7 to 8 (like moderately to like very much; used 9 Points Hedonic Scale method for the sensory test) the characteristic for color was 7.37+ 0.01 texture in crisp was 7.33+ 0.01 and overall acceptance was 7.70+ 0.01. Especially odor was 7.63+ 0.01 and taste was 7.38+ 0.03 there were significant differences (p<0.05) with 0 and 6% grinded sugar. TLHSP was well accepted by consumers with 88.00% (By the Central Location Test for questionnaire paper survey). Almost 70% were female 88% had 18-27 years-old 81% were student and 56% hadincome cash < 5001 baht/ months. This study used the extrusion technology to produceTLHSP which the fixed specification fallow as; a speed of single screw was 300 rpm Barrel temperature was 134-165 ˚C 380 Volt 85 amp a diameter in front of machine was 2 mm. a speed of blade 95 rpm and had 2 pieces. And the capacity was 14.4 kg/hr. Therefore aw0.34±0.02 Lightness 60.41 ± 0.16 %extended ratio1.69±0.01 %bulk density 0.15± 0.001. Chemical Properties for %moisture6.60±0.16 %protein 7.88±0.16

The research regarding effect of nanotechnology use in making chef apparel on safety of food had the objectives to study about the result of using nano materials coating on yarn and fabric; to study about the use of nano materials which are suitable for fabric to be sewn for being chef apparel and to study the effect of using of nanotechnology for chef apparel on smell and the inhibition of pathogenic bacteria growth using three types of nano materials including Zinc oxide nano Silver nano and Titanium dioxide nano to be coated on four samples including cotton thread T/R thread cotton fabric and T/R fabric. The researcher tested the fabric sample for inhibiting growth of pathogenic bacteria and found that Zinc oxide nano and Silver nano were not different in inhibiting growth of pathogenic bacteria. But the coating on the fabric is more convenient and cheaper. And effective against Gram-positive bacteria. A bacterium that is often found in personal hygiene unclean conditions better than or equal to SS.S3%. Then Four kinds of fabric were sewn to be chef apparel. Actual chef tried wearing to test effectiveness in resisting bacteria. When the apparel was used for two times it was found that T/R fabric which was coated with Zinc oxide nano and Silver nano had different ability to resist gram-positive bacteria and gram-negative bacteria. Fabric T/R Silver nano coating remains effective against bacteria as well and proper to be sewn as chef apparel.
