Quantitative losses in various biochemical constituents like capsaicin, carotenes, ascorbic acid, polyphenols, mineral matter, sugars (soluble and insoluble), protein and fat were estimated after the successful growth of Aspergillus flavus for 30 days on powdered red pepper. The fungal biomass was measured by ergosterol content and Aflatoxin B1 by HPLC. Amongst the various nutritional constituents evaluated for nutritional losses and changes the highest nutritional loss was reported in total carotenoids (88.55%) followed by total sugars (85.5%). The protein content of the infected sample increased from 18.01% to 23%. The nutritional profile of chilli powder (Capsicum annum var. sannam L.) shows highest share of total soluble sugars (32.89%) and fiber content (21.05%), followed by protein (18.01%) and fat (13.32%) making it an ideal solidsubstrate for mould growth. At the end of incubation the fungal biomass was 192. 25 mg / 100 gram powder, total plate count 17.5 X 10 4 CFU/g and Aflatoxin B1 content was 30.06 µg / kg.

Dried red chilli samples kept in cold stores for varying periods (6–30 months) were collected at monthly intervals for 1 year and observed for mycoflora. Surface‐sterilized and unsterilized chilli pods were placed on Czapek‐Dox agar medium to study the incidence of fungi. In all the samples, incidence of Aspergillus flavus and Aspergillus niger was very high followed by Mucor spp., Fusarium spp. and Alternaria alternata. Attempts to estimate the biochemical constituents, such as total protein, carbohydrates, reducing sugars, ascorbic acid and total phenols in cold‐stored red chillies, revealed a gradual decrease in the levels of these components with extending storage period. Screening of chilli pods for the natural occurrence of mycotoxins indicated the presence of aflatoxin B1 in cold‐stored chillies. PRACTICAL APPLICATIONS Chillies are an important condiment in the Indian household. Chillies have great international market value and are used as natural colorant instead of artificial colorants in cosmetics, pharmaceutical applications and processed foods. The use of commercial cold stores for chilli storage has now become a general practice among farmers in order to fetch premium price due to excellent retention of color. Chillies could be contaminated with toxigenic molds under processing factors like improper drying of pods before storage. Temperature, relative humidity and storage period in cold storage are important factors that influence frequency of molds and their toxin production. Quality of chilli fruits are also greatly affected by high frequency of molds. Incidence of Aspergillus flavus and their aflatoxin B1 is increased when storage period extends. This study provides very important information that is useful for the chilli farmers and exporters in maintaining proper processing and storage conditions. Chilli traders can utilize the methods presented in this article to assess the quality of fruits such as toxin content and biochemical constituents.

“…This is in contrast to the invasion of Indian red pepper seeds by Aspergillus halophilicus, where appressoria and infection pegs were observed (Seenappa et al 1980). It is not known whether this difference is due to structural characteristics of the seed epidermal layers or to the infective capabilities of the two fungal species.…”

“…on clover (Kellock et al 1980), and corn (Lawrence et al 1981); and Verticillium on lupin (Parnis & Sackston 1979). Studies of postharvest fungi invading mature seeds have included Aspergiilus flavus, Aspergiilus halophilicus, and Aspergiilus glaucus group species on wheat, tomato, pea, squash, and Indian red pepper (Anderson et al 1970, Harman & Granett 1972, Harman & Pfleger 1974, Seenappa et al 1980. Of these studies, only those by Anderson et al (1970) and Harman and Granett (1972) involved ultrastructural methods.…”
