Problems solved by technology

Blueberry pulp is delicate, sweet and sour, and unique in flavor, which is very suitable for the processing of blueberry jam. At present, the traditional processing method is adopted for the jam circulating in the market in my country, that is, the total sugar content is as high as 65% to 70%. Preservability, but it consumes a lot of sugar, high sweetness, and high calories, which can no longer adapt to the development trend of low calorie and low sweetness in the food industry.

Abstract

The invention discloses a making technology for blueberry jam. The technology comprises the steps of cleaning, crushing, burdening, vacuum concentration, tinning, sealing, sterilization, cooling and the like. White granulated sugar is added with water for boiling for 10 min, the mixture is filtered through a filter cloth in a syrup filter, the filter cloth is of the 100-mesh size, impurities in sugar solution are removed, and the sugar solution with the mass concentration being 40-50% is obtained for use; citric acid is made into a solution with the mass concentration being 40% for use; modified starch, xanthan gum and sodium carboxymethylcellulose are selected as a jam thickening agent, the xanthan gum and the sodium carboxymethylcellulose are sufficiently mixed with a part of white granulated sugar to be slowly added into continuously-blended hot water at the temperature of 50 DEG C, and then a complexation masking agent is added till sufficient dissolution to be added into a pill tank; the modified starch is directly dissolved while being blended in warm water and slowly added into the pill tank; acetic acid is adopted for adjusting the pH to be 3, and a gel complexing agent and abrowning inhibitor are added into the pill tank. The blueberry jam has the advantages of being low in sugar, nutritive and safe.

Description

【Technical field】 [0001] The invention relates to the technical field of jam preparation technology. 【Background technique】 [0002] Blueberry belongs to Rhododendronaceae Vaccinium plant, scientific name Vaccinium. Its fruit is a berry, dark blue, covered with hoarfrost, nearly round, with thin skin and small seeds, and has extremely high nutritional value. In addition to being rich in carbohydrates, proteins, vitamins, and minerals, blueberries also contain a lot of vitamins, superoxide dismutase, anthocyanins, tannic acid, folic acid, and flavonoids, which make blueberries prevent neural aging and strengthen the heart. Function, eyesight and unique anti-cancer effects [2-5]. Therefore, the Food and Agriculture Organization of the United Nations lists it as one of the five health foods for human beings. In recent years, blueberries have developed rapidly in my country. With the rapid development of the industry, deep processing has become the only way to solve the probl...
