Since pH has a profound effect on anthocyanin stability and color expression and Ca plays a major role in maintaining the texture of strawberries. For achieving high quality frozen strawberries, a combination of 0.4% citric acid with different levels of Ca lactate dips was used for pre freezing treatments. The experimental results are presented in Table 3. Generally, slight differences are observed between citric acid – Ca lactate combination treatments frozen directly and after cooling for overnight. Adhering 0.4% citric acid in Ca lactate dips pre freezing treatments lead to relative improvement in quality indices, where drip loss reduced by 61–132% relative to untreated and by around 12–19% compared to Ca lactate treatments and by around 44–105% for 0.4% citric acid treatment while firmness raised by around 34–69%, 14–18% and 39–64% for untreated, Ca lactate and 0.4% citric acid treatments, respectively. A considerable reduction in browning index was also observed. The retention of both ascorbic acid and anthocyanin content was noticeably increased by 46– 57% and 34–37% compared to untreated and by around 25– 27% and 21–31% relative to Ca lactate treatments and by around 21–37% and 3–8% for 0.04% citric acid treatment, respectively. In a study on improving quality of home frozen strawberries, added calcium lactate, ascorbic acid, citric acid and tartaric acid alone or in combination to a 60 (w/V) sugar syrup held in storage for up to 3 months. Citric acid gave the best color and overall rating whereas calcium lactate and ascorbic acid improved firmness, suggesting that combinations might be best (see Fig. 2).
