การศึกษาการใช้ Lactobacillus caseiในการผลิตนมเปรี้ยวโพรไบโอติก มีวัตถุประสงค์เพื่อศึกษาปริมาณ Lactobacillus caseiที่เหมาะสมในการผลิตนมเปรี้ยวโพรไบโอติก ศึกษาลักษณะทางด้านกายภาพ เคมี จุลินทรีย์ อายุการเก็บรักษา และศึกษาการยอมรับของผู้บริโภคโดยการทดสอบทางประสาทสัมผัส โดยมาทาการวางแผนการทดลองแบบสุ่มสมบูรณ์ในบล็อก (Randomized Completely Block Design ; RCBD) และทางกายภาพ ทางเคมี ทางจุลินทรีย์ของนมเปรี้ยวโพรไบโอติกโดยใช้ Lactobacillus caseiทาการทดลองในอัตราส่วน หางนมผง : น้า เท่ากับ 1.3 : 8.7 นาไปให้ความร้อนที่อุณหภูมิ 90 - 95 oC เป็นเวลา 1.30 ชั่วโมง จากนั้นนานมมา cooling ให้นมมีอุณหภูมิที่ 37 oC ใส่ standard culture 20 มิลลิลิตร นาไปบ่มที่อุณหภูมิ 37 oC เป็นเวลา 3-5 วันทาการศึกษาปริมาณน้าเชื่อมแตกต่างกัน 3 ระดับ คือ 10 15 และ20 กรัม ทดสอบการยอมรับจากผู้บริโภคด้วยวิธีการให้คะแนนความชอบ 9 ระดับ (9-point hedonic scale) นานมเปรี้ยวโพรไบโอติกที่ผู้บริโภคยอมรับมากที่สุด คือ 15 กรัม มาวัดค่าทางกายภาพ ทางเคมี และทางจุลินทรีย์ ผลการศึกษาพบว่า นมเปรี้ยวโพรไบโอติกมีสีครีมออกเหลือง มีปริมาณของแข็งที่ละลายได้ในน้า 12.63 ± 0.01oBrix มีไขมันน้อยกว่า1เปอร์เซ็น มีความเป็นกรด–ด่าง 3.76 ± 0.02 มีกรดแลกติก1.07 ± 0.01 เปอร์เซ็นต์มีปริมาณ Lactobacillus casei CFU/cm3เท่ากับ 1.8×107 และมีอายุการเก็บรักษา นาน 7 วัน ที่อุณหภูมิ 4-8 oC

Khao’ Niao Dam is a grain which has anthocyanins pigment. Rice flours contained high protein content more than white grain and have higher water absorption. The white rice flour had higher swelling power and lower solubility than 6 rices flours. Amylose which content in the white rice flour is peak viscosity final viscosity setback and pasting temperature than the waxy rice flours. The objectives of this research were to formulate and determine the appropriate condition for sensory test on the rices powdered beverage products to consumers in terms of color flavor sweet taste viscosity and preference overall. Starting from the basic formula 3 formula is a formula that consists of Germinated brown rice drying were 23.33 % millet drying were 3.33% soybean powder were 6.67% powdered milk were 13.33% sugar were 33.33 % and cream powder were 20.00%. Acceptance scores of 7.60 and then to research the use of Germinated brown rice drying a substitute for cream powder in the manufacture of rice powder beverages into 3 levels such as 50 75 and 100% the amount of Germinated brown rice drying a substitute for cream powder 100 % has been the most acceptance. Then the ratio of rice flour 7 the appropriate type of beverage rice powdodor and viscosity of the beverage rice powder for 3 formulas were formulated with Black Glutinous flour were 10.00% the most acceptance. The study of soybean powder substitute millet powder in the manufacture of rice powder beverages to reduce the viscosity into 3 levels: 50 75 and 100%. The result showed that the suitable of soybean powder substitute millet powder were 100% and the most acceptance. This study used amount of soybean powder and milk powder substitutes sugar in the production of powdered rice beverage can be divided into 3 levels in the formula is 5 10 and 15% the result showed that the 10% of the soybean powder and 15% of milk powder substitutes sugar the most acceptance. Then study the temperature of water for rice powder beverages and the ratio of water to the rice powder beverages in the rice powder is 1:5. Nutritional value analysis of rice beverage product showed were 6.46% moisture 11.63% protein 7.34% fat 5.65% dietary fiber 1.47% ash and 67.45% carbohydrate and the shelf-life of rices powdered beverages which pack in aluminum foil bags was preserve products and store at 30 °C more than 6 weeks.

The study of utilizing core pineapple and phufa tea in drinking jelly. The purpose of this study and processing in add fiber from core pineapple wasted and Phufa tea in drinking jelly. The resulfs showed that formulation of carageenan was 10 gram because texture had elastic and softness appropriate. Ratio core pineapple juice : Phufa tea was 60 : 40 percentage had sensibility in color order and flavor for Phufa tea and add fiber from core pineapple was 10 gram because texture had elastic softness and easily suck. The consumer acceptability indicated of target consumer accepted the product. Consumer accepted like very much 41% and interested to buy product 83%. The physical attributes were as follows : L* a* b* value 75.20±0.01 1.31±0.01 28.43±0.02 and respectively Aw = 0.973±0.00 and hardness 5.42±0.45 (N). The chemical analysis of product contained pH = 3.52±0.02 Total soluble solid (TSS) = 15±0.00 (°Brix) and crud fiber content 0.602%. The microorganism (TPC) < 10 cfu/g. and yeast and mold < 10 cfu/g.

The objective of this study is to survey consumer behavior’s want in using mushroom replace of fat in the vietnamese sausage. The result of this survey is the choosing Phutan oyster mushroom to use replace of fat. Studying the basic method in producing the vietnamese sausage by studying the amount of fat at 40 60 and 80 grams The result of this the vietnamese sausage that has 80 grams fat because emulsion in the fat makes the vietnamese sausage soft and delicious. And study about the amount of mushroom at 80100 and 120 grams replace of fat The result of this the vietnamese sausage that has the mushroom 100 grams because the vietnamese sausage is the softest and springiness has the weakest smell of mushroom. This compare the original vietnamese sausage with the study on fat replacement by mushroom in vietnamese sausage found that the mushroom vietnamese sausage has the fat lower than the vietnamese sausage 12.78 fold and the most fiber 5.33 fold. Studying self life of the mushroom vietnamese sausage at 5-8.C found that Aw color and the moisture content increase and test about microbe TPC in this product is less than 10 cfu/g and lower than the benchmark (it must be lower that 1x103 for 1 gram). Acceptant the most consumers moderately.

The purposes of this study were to study amount modified starch substitution by rice canned mackerel in tomato sauce seasoned with black pepper ratio at 15:85 20:80 and 25:75 percentage. The results showed that the best formulation of product was rice flour (percentage) 20:80 because sauce in can were red orange pH of sauce was = 6. The result of the study showed that the physical and chemical attributes of product canned mackerel in tomato sauce seasoned with black pepper compared with control. Found that canned mackerel in tomato sauce seasoned with black pepper of dark orange more than control. pH = 6.05 – 6.15 were similar moisture protein fat and carbohydrate content but the differences in ash content. The consumer acceptability indicated of target consumer accepted the product consumer need to buy this product 79% like moderately this product 72% and suitable price about 15 bath/can. The product of storage 6 mouths and not detects mesophilic aerobic bacteria and thermophilic aerobic bacteria.
