The invention discloses a preparation method of salty sour horn juice, which relates to the technical field of food processing. The method comprises the steps of selecting beans, drying, shelling, dry heat treatment, natural fermentation, extracting sour horn juice, filtering, removing impurities, dispensing and filling, as well as the steps of acid removal and astringency removal. The deacidification is as follows: adding 0.5 1.5% modified chitosan into filtered sour horn juice after impurities removal, stirring evenly in constant temperature water bath, stationary, centrifuging, filtering and collecting when the acidity is reduced to 0.8 1.2%. De-acid horn juice is obtained by collecting filtrate and adding 1 2% okra extract to the de-acid horn juice to mix, and then standing at 0 5 C until precipitation, filtering and collecting filtrate to obtain the De-astringent acid horn juice. By optimizing the preparation method, the acidity and astringency are reduced, the acidity of the sour horn juice is moderate, slightly salty, the taste is soft, the taste and quality are improved, and there is no need to add sugar to mix, so the sour horn juice is suitable for the use of diabetic patients.

一种咸味酸角汁的制作方法
本专利技术涉及食品加工
,具体涉及一种咸味酸角汁的制作方法。
技术介绍
酸角又称酸豆、罗望子、酸果,属豆科酸角属,热带、亚热带常绿大乔木。酸角果肉中富含糖、有机酸、蛋白质、氨基酸、维生素、矿物质(以钙、钾和磷为主,较少为镁和锌)、多酚等营养物质,其中,还原糖、总酸、多糖含量分别高达36.8%、14.2%和12.4%,粗蛋白质含量高达6.79%,氨基酸含量高达5.79%,适合加工成系列保健饮品。酸角果肉中的酸主要为酒石酸、枸橼酸、琥珀酸、柠檬酸、醋酸和蚁酸,直接制成饮品酸性较强,需添加大量的糖来弱化酸度,以提高适口性,但高糖饮料不健康,也不适合一些特殊的人群饮用,如糖尿病患者。专利CN201510111987一种酸角汁的加工方法公开了向酸角汁中加入蔗糖调节酸度,使糖酸比例为38:1。可见酸角汁酸度很高,需添加38倍的糖进行调节,使饮品中含糖量极高,不适合糖尿病患者大量饮用。非专利文献“罗汉成品的壳聚糖脱酸工艺研究”(唐峰等,《广西轻工业》1999年03期)公开了壳聚糖可将果肉中的柠檬酸、酒石酸等有机酸去除,使罗汉成品的pH值由 ...
