چکیده

در این پژوهش اثر متغیرهای مؤثر محتوای رطوبتی، اندازه ذرات، نوع ماده چسبان و شکل قرص بر خواص کیفی (اختلاف شاخص‌های رنگی∆L*،∆a* و ∆b*) ، فیزیکی (چگالی واحد و چروکیدگی) و مکانیکی (نیروی نفوذ) قرص فشرده تولید شده از پودر گوجه‌فرنگی مورد مطالعه قرار گرفتند. متغیرهای مستقل شامل سه سطح اندازه ذرات پودر گوجه‌فرنگی (ذرات کوچک‌تر از mm 3/0، ذرات بین3/0 تا mm 75/0 و ذرات بزرگتر از mm 75/0)، سه سطح محتوای رطوبتی (18، 36 و d.b.54%)، سه شکل قرص فشرده (کروی، استوانه‌ای و مکعبی) و سه نوع ماده چسبان (شربت فروکتوز 55 درصد، آب و شکر) بودند. برای بهینه‌سازی از روش سطح پاسخ و طرح دی- اپتیمال استفاده شد. نتایج نشان داد که نقطه بهینه برای قرص­های فشرده شده متشکل از پودر گوجه‌فرنگی با محتوای رطوبتی % d.b. 4/33، اندازه ذرات mm 3/0، نوع ماده چسبان فروکتوز و شکل قرص استوانه‌ای که در آون در دمای °C60 خشک‌شده بودند به دست آمد. تحت این شرایط، شاخص مطلوبیت 826/0 محاسبه شد و مقدار بهینه متغیر­های مستقل∆L*، ∆a*و ∆b*، نیروی نفوذ، چگالی واحد و چروکیدگی به ترتیب برابر با 89/35، 6/51، 23/23، N 2/267 ، kg/m3 2299 و 12/2 درصد به دست آمدند.

چکیده [English]

In this study, the effect of effective variables of moisture content, particle size, type of adhesive and tablet shape on the qualitative properties (difference of color indices ΔL*, Δa* and Δb*), physical (unit density and shrinkage) and mechanical (diffusion force) indices of compressed tablets made from tomato powder were studied. Independent variables were including three levels of particle size of tomato powder (particles smaller than 0.3 mm, particles ranging from 0.3 to 0.75 mm and particles larger than 0.75 mm), three levels of moisture content (18, 36 and d.b. 54%), three forms of compressed pills (spherical, cylindrical and cubic), three types of adhesive (55% fructose syrup, water and sugar). For optimization, the surface response and Di-optimal method were used. The results showed that optimum spot was obtained for compressed pills consisting of tomato powder with a moisture content of %33.4 db, particle size of fructose 0.3 mm, and cylindrical tablet form, dried in oven at 60 ° C. Under these conditions, the desirability index was 0.826, and the optimal value of the independent variables ΔL*, Δa* and Δb* (the difference of color indices with fresh tomatoes), penetration force, unit density and shrinkage were 35.89, 15.6, 23.23, 267.2 N, 2299 kg/m3 and %12.2, respectively.
