Abstract

We studied suitable dough formula for yeast-raised breadmaking using frozen dough prepared by straight no-time method, centering around breadmaking quality. The most suitable dough formula based on 1,000 g of wheat flours was as follows : compressed yeast ; 30 g, sucrose ; 50 g, salt ; 20 g, shortening ; 40 g, potassium bromate ; 75mg, L-ascorbic acid ; 200mg, yeast food ; 3 g, vital wheat gluten ; 30 g, calcium phosphate, monobasic ; 400mg, sodium stearoyl-2-lactylate ; 8 g, water ; 680 g. Breadmaking test employing this formula showed that gassing power and fermentation time were suitable and higher specific loaf volume was obtainable. By using much emulsifiers and dough conditioners, frozen injury of dough was controlable in spite of the addition of more content of water(68%) than that of water (62%) obtained from the farinograph data.

Straight no-time method로 조제한 냉동(冷凍)반죽을 이용(利用)한 발효(醱酵)빵제조에 있어서 가장 적절한 반죽의 조성(組成)을 제(製)빵성적(成積)을 중심으로 검토하였다. 경질(硬質)밀가루 1,000 g에 대하여 압착효모(壓搾酵母) 30 g, 설탕 50 g, 식염(食鹽) 20 g, 쇼트닝 40 g, 브롬산칼륨 75mg, L-ascorbic acid 200mg, yeast food 3 g, vital wheat gluten 30 g, 제1인산칼슘 400mg, 스테아릴젖산나트륨 8 g, 급수량(汲水量) 680 g 으로 냉동(冷凍)반죽을 만드는 것이 제(製)빵과정(過程)에서 팽창력(膨脹力)과 발효시간(醱酵時間)이 적절하고 높은 비용적(比容積)을 얻을 수 있어서 가장 바람직하였다. Farinograph 성적상의 흡수율(吸水率)보다 높은 68%의 급수량(汲水量)으로도 유화제(乳化劑)나 품질개량제(品質改良劑)의 다량첨가(多量添加)로 반죽의 동결장해(凍結障害)를 억제할 수 있었다.
