Helbat (hl'bət), a fasting semi-liquid condiment, is a popular indigenous traditional fermented product in Tigrai (a.k.a. Tigray), Ethiopia. It is formulated using flour prepared from mildly roasted dry beans. Despite its dietary, nutritional, religious, and cultural significance, the condiment is yet not exposed to scientific study. Hence, this research was carried out to: (a) ascertain the best faba bean variety for preparing high quality , (b) develop the formulation and preparation protocol of high quality , (c) determine the effects of fermentation and storage temperature and time on the physicochemical characteristics, proximate and mineral compositions, microbiological properties, and sensory qualities of , and (d) determine the shelf life of as the function of storage time and temperature. To this end, three faba bean varieties used in preparing as well as fermenting and stored products were studied using standard physicochemical, microbiological, and sensory evaluation procedures. Quantitative data were processed using inferential statistical methods and mean (±SD) values were compared at set -value of ≤0.05. The study showed that: (a) the best faba bean variety for making high quality was ; (b) the best formulation constituted 400 wt units of bean flour, 7 wt units of garlic, 6 wt units of ginger, 5 wt units fenugreek, 5 wt units of corrorima, 8 wt units of red pepper, and 3 wt units of black mustard; (c) the best formulation was nutritionally rich to supplement fasting consumers with proteins, fats, and minerals; (d) the formulation remained safe for up to eight weeks while maintaining its attractive sensory qualities when stored at 11-15 °C, and (e) increasing the fermentation and storage times led to changes in its physicochemical properties (i.e., temperature, pH, total titratable acidity, and total soluble solute) and depletion of many nutritionally vital components such as fats, proteins, and minerals. Thus, unless production and storage conditions are somehow modified, needs to be consumed fresh after three to seven days of fermentation. But further research may be required to make this recommendation conclusively. Exploring into its antioxidant properties and lactic acid bacteria (LAB) may highlight its qualities further.
海尔巴特(hl'bət)是一种禁食的半流质调味品,是埃塞俄比亚提格雷(又称提格雷)一种受欢迎的本土传统发酵产品。它是用轻度烘焙的干豆制成的面粉配制而成。尽管这种调味品在饮食、营养、宗教和文化方面具有重要意义,但尚未进行科学研究。因此,开展本研究的目的是:(a)确定制备高品质海尔巴特的最佳蚕豆品种;(b)制定高品质海尔巴特的配方和制备方案;(c)确定发酵和储存温度及时间对海尔巴特的理化特性、近似成分和矿物质组成、微生物特性及感官品质的影响;(d)确定海尔巴特作为储存时间和温度函数的保质期。为此,使用标准的理化、微生物和感官评价程序,对用于制备海尔巴特以及发酵和储存海尔巴特产品的三个蚕豆品种进行了研究。定量数据采用推断统计方法进行处理,并在设定的≤0.05的P值下比较均值(±标准差)。研究表明:(a)制作高品质海尔巴特的最佳蚕豆品种是[具体品种未给出];(b)最佳海尔巴特配方由400重量单位的豆粉、7重量单位的大蒜、6重量单位的生姜、5重量单位的胡芦巴、5重量单位的科罗里马、8重量单位的红辣椒和3重量单位的黑芥子组成;(c)最佳海尔巴特配方营养丰富,可为禁食的消费者补充蛋白质、脂肪和矿物质;(d)当在11 - 15°C下储存时,海尔巴特配方在长达八周的时间内仍保持安全,同时保持其诱人的感官品质;(e)增加发酵和储存时间会导致其理化性质(即温度、pH值、总可滴定酸度和总可溶性溶质)发生变化,并使许多营养重要成分如脂肪、蛋白质和矿物质减少。因此,除非以某种方式改变生产和储存条件,否则海尔巴特在发酵三到七天后需要新鲜食用。但可能需要进一步研究才能最终得出这一建议。对其抗氧化特性和乳酸菌(LAB)的探索可能会进一步突出其品质。
